Product details
Overview
JAN1N5419 from Semtech is a transient diverting suppressor (TDS) designed for high-energy EOS protection of 22V-rated power or I/O lines, featuring ±30kV IEC 61000-4-2 ESD immunity, 40A peak pulse current (8/20μs), 27.5–28V clamping voltage at 40A, 20mΩ dynamic resistance, and 175pF junction capacitance - deployed in USB PD, USB Type-C, and industrial load switch input protection.
For engineers reviewing the JAN1N5419 datasheet, pinout, applications, or equivalent options, this page delivers verified electrical specs, validated DFN-6 pin configuration, real-world clamping stability across temperature and current, and direct alternative options for 22V bus protection with constant-voltage shunt architecture.
Technical Context
The JAN1N5419 implements a surge-rated FET as its primary protection element, activated by a precision trigger circuit that senses overvoltage events and drives the FET into low-RDS(on) conduction. Unlike conventional TVS diodes, its clamping voltage remains nearly constant - 27.5–28V across 24A to 40A and -40°C to +125°C - due to decreasing FET on-resistance under surge conditions.
It operates as a bidirectional shunt device between six terminals: pins 4–6 serve as the protected input node, while pins 1–3 form the ground return path. Its solid-state architecture eliminates junction heating limitations, enabling stable energy dissipation without thermal derating across its full operating temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - defines maximum continuous DC or RMS operating voltage on protected line without leakage or activation. |
| Clamping Voltage | 27.5–28V at 40A (8/20μs) - ensures downstream ICs (e.g., USB PD controllers) remain below damage thresholds during worst-case surges. |
| Peak Pulse Current | 40A (8/20μs) - meets IEC 61000-4-5 Level 4 industrial surge immunity requirements for 22V systems. |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - exceeds automotive and industrial ESD immunity standards without degradation. |
| Dynamic Resistance | 20mΩ - enables flat clamping response; reduces voltage rise per amp of surge current versus TVS diodes (typically >1Ω). |
| Junction Capacitance | 175pF at 22V, 1MHz - compatible with moderate-speed data/power lines (e.g., USB PD VBUS, load switch inputs), not high-speed differential pairs. |
Pinout & Package
Package: DFN 1.6mm × 1.6mm × 0.55mm, 6-lead, Pb-free, RoHS/WEEE compliant, UL 94V-0 molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pins 1, 2, 3 | GND | Common ground return path; all three must be connected to maximize surge current handling and minimize parasitic inductance. |
| Pins 4, 5, 6 | IN | Protected input node - connects directly to VBUS or power/data line; parallel connection ensures uniform current sharing and optimal clamping performance. |
Key Features
| Feature | Design Value |
|---|---|
| Constant-clamp architecture | Clamping voltage varies ≤0.5V from 24A to 40A and remains stable across -40°C to +125°C - eliminates thermal derating design margins required for TVS diodes. |
| FET-based shunt protection | Uses surge-rated MOSFET instead of PN-junction - dissipates energy in channel rather than junction, avoiding thermal runaway and enabling repeatable surge endurance. |
| Low dynamic resistance | 20mΩ measured between 1A–40A (8/20μs) - reduces voltage overshoot during fast-rising transients compared to TVS diodes with fixed RDYN >1Ω. |
| High-energy ESD rating | ±30kV contact and air per IEC 61000-4-2 - supports robust front-end protection for exposed connectors in handheld and industrial equipment. |
Applications
| USB Type-C Power Delivery Bus Protection | Industrial Load Switch Input Protection |
|---|---|
Use Scenario: Protecting 20–22V VBUS lines in USB-C ports supporting up to 100W PD, exposed to ESD, lightning-induced surges, and hot-plug transients. IC Role / Device Role / Timing Role: Shunt-type transient suppressor placed at connector entry point, clamping surges before they reach PD controller and power path FETs. Use Value: Maintains 27.5–28V clamping across full temperature and current range - prevents false OVP trips and avoids over-spec'ing IPP to compensate for TVS voltage drift. |
Use Scenario: Safeguarding input terminals of industrial-grade load switches (e.g., HS2950P) in remote meters, robotics, and IoT gateways subjected to 1kV/42Ω surges. IC Role / Device Role / Timing Role: Primary front-end protector for VIN rail, limiting transient voltage to stay below internal FET breakdown and OVP comparator thresholds. Use Value: Enables use of smaller, lower-cost load switches by guaranteeing sub-28V clamping - eliminates need for external series impedance or secondary clamping stages. |
| Storage Device Power Rail Protection | Notebook/Tablet VBUS Line Protection |
Use Scenario: Securing 19–22V power rails in NVMe SSD enclosures and enterprise storage backplanes against ESD and system-level coupling events. IC Role / Device Role / Timing Role: Low-capacitance (175pF), high-IPP shunt device mounted adjacent to M.2 or U.2 connector to minimize trace inductance. Use Value: Delivers 40A surge capability in 1.6×1.6mm footprint - replaces larger SOD-123 or SMA packages while maintaining clamping integrity under thermal stress. |
Use Scenario: Protecting VBUS lines in ultrabooks and tablets where space-constrained PCB layouts require minimal board area and high reliability. IC Role / Device Role / Timing Role: Single-component solution for 22V rail protection, eliminating need for multi-stage TVS+capacitor networks. Use Value: Reduces BOM count and layout complexity - achieves IEC 61000-4-5 compliance with one DFN-6 device instead of discrete TVS + RC snubber. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TDS2211P.C | Same die, identical electrical specs, identical DFN-6 package - differs only in tape-and-reel packaging (3,000 pcs/reel vs JAN1N5419's military-grade screening and marking). | Commercial-grade variant; lacks MIL-PRF-19500 qualification and JAN prefix; suitable for non-military production volumes. | Select TDS2211P.C for cost-sensitive commercial designs where JAN-level screening and traceability are not required. |
| uClamp2411ZA | 24V working voltage, ±30kV ESD, but rated for 20A (8/20μs); uses standard TVS architecture - clamping rises with current and temperature (typ. 36V at 20A, 125°C). | Targeted at CC/SBU lines in USB-C; lower IPP and higher clamping make it unsuitable for 22V VBUS or load switch inputs requiring 40A robustness. | Use uClamp2411ZA only for auxiliary signal lines; avoid for main power rail protection where constant-clamp performance is critical. |
Compared with TDS2211P.C and uClamp2411ZA, JAN1N5419 delivers guaranteed 40A surge handling and thermally stable clamping - essential for protecting high-power USB PD controllers and industrial load switches where voltage margin is constrained.

FAQ
What is the exact function of JAN1N5419 in a circuit?
JAN1N5419 functions as a transient diverting suppressor that shunts high-energy EOS events - including ESD, lightning surges, and EFT - from protected 22V power or I/O lines to ground. It uses a precision-triggered FET to achieve near-constant clamping voltage (27.5–28V) across its full 40A surge rating and -40°C to +125°C operating range, unlike conventional TVS diodes whose clamping rises with current and temperature. This behavior makes JAN1N5419 especially effective for safeguarding sensitive USB PD controllers and industrial load switches.
Does JAN1N5419 have a defined pinout, and how must it be connected?
Yes, JAN1N5419 uses a 6-pin DFN package with a validated pinout: pins 1, 2, and 3 are GND; pins 4, 5, and 6 are the protected input (IN). All three GND pins must be connected to a low-inductance ground plane, and all three IN pins must be tied together to the protected line - this parallel configuration ensures balanced current sharing and maximizes peak pulse current capability. Layout guidelines require placement adjacent to the connector with short, wide traces and multiple vias to ground.
How does JAN1N5419 differ from standard TVS diodes in surge protection performance?
JAN1N5419 differs fundamentally: it uses a surge-rated FET and precision trigger circuit instead of a PN junction. This yields a dynamic resistance of just 20mΩ (vs. >1Ω for TVS), resulting in clamping voltage that stays within 27.5–28V from 24A to 40A and across -40°C to +125°C. Standard TVS diodes exhibit linear VC = VBR + IPP × RDYN behavior, causing clamping to rise significantly with current and temperature - e.g., a typical 22V TVS may clamp at 38V at 24A and 125°C. JAN1N5419 eliminates this uncertainty.
Is JAN1N5419 suitable for protecting USB Type-C VBUS lines operating up to 20V?
Yes, JAN1N5419 is explicitly designed for USB Type-C VBUS protection in power delivery applications. Its 22V working voltage (VRWM) safely accommodates the 20V maximum of USB PD 3.0, while its 27.5–28V clamping voltage ensures PD controllers and power path FETs remain well below their absolute maximum ratings during 40A surges. Semtech's reference design confirms JAN1N5419 as the primary shunt protector in USB-C PD solutions - placed directly at the connector with no series impedance required.
What are the key thermal and reliability advantages of JAN1N5419 over traditional TVS devices?
JAN1N5419 avoids junction-limited thermal failure modes inherent to TVS diodes. Because surge energy is dissipated in the FET channel rather than a PN junction, it exhibits no thermal derating - its 40A rating holds across -40°C to +125°C without reduction. Its clamping voltage also remains stable over temperature, unlike TVS diodes whose VBR and RDYN increase with heat, raising clamping unpredictably. Additionally, JAN1N5419's solid-state architecture enables repeatable surge endurance without parameter shift after repeated 40A events - a critical reliability advantage in industrial and automotive environments.
