Product details
Overview
JAN1N5554 from Semtech is a transient diverting suppressor (TDS) designed for high-energy EOS protection on 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, and 20mΩ dynamic resistance - deployed in USB Type-C PD input protection and industrial load switch front-end circuits.
For engineers reviewing the JAN1N5554 datasheet, pinout, applications, or equivalent options, this page delivers verified electrical parameters, DFN-6 package layout guidance, real-world clamping stability data across temperature and current, and direct alternative options for 22V bus protection with constant-voltage suppression behavior.
Technical Context
The JAN1N5554 uses a surge-rated FET as its primary protection element, activated by a precision trigger circuit that turns on the shunt path when transient voltage exceeds breakdown. Unlike conventional TVS diodes, its clamping voltage remains nearly constant (27.5–28V) from 24A to 40A due to decreasing RDS(on) under surge conditions.
It operates over –40°C to +125°C with stable junction capacitance (175pF @ 22V, 1MHz) and reverse leakage (<600nA @ 22V), and is rated for 1120W peak pulse power. Its functional architecture eliminates voltage-dependent clamping rise and thermal derating limitations typical of pn-junction TVS devices.
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 conduction. |
| Clamping Voltage | 27.5–28V @ 40A (8/20μs + 1.2/50μs combo wave, RS = 2Ω) - ensures downstream 24V-rated ICs (e.g., USB PD controllers) remain below damage threshold during surge. |
| 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 Level 4 ESD immunity for handheld and interface connectors. |
| Dynamic Resistance | 20mΩ - enables low-voltage overshoot and minimal IR drop during high-current transients, critical for tight voltage-margin designs. |
| Junction Capacitance | 175pF @ 22V, 1MHz - compatible with medium-speed bus protection (e.g., USB 2.0, SMBus, industrial I/O) without signal integrity degradation. |
Pinout & Package
Package: DFN 1.6mm × 1.6mm × 0.55mm, 6-lead, Pb-free, RoHS/WEEE compliant, UL 94V-0 molding compound. Exposed thermal pad not required - energy dissipated via FET channel, not junction heating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | GND | Common ground return for surge current; all three pins must be connected to maximize current sharing and minimize parasitic inductance. |
| 4, 5, 6 | IN | Protected line input (e.g., VBUS, load switch input); all three pins are internally tied and must be shorted externally for full 40A rating. |
Key Features
| Feature | Design Value |
|---|---|
| Constant-clamp architecture | Clamping voltage varies ≤0.5V across 24–40A surge range - eliminates design margin inflation needed with traditional TVS diodes. |
| Temperature-stable clamping | Clamps at ~27.5V from –40°C to +125°C - removes thermal derating calculations for industrial ambient conditions. |
| Low dynamic resistance | 20mΩ enables <0.8V additional overshoot at 40A - preserves voltage headroom for 24V logic and analog interfaces. |
| High-energy capability | 1120W peak pulse power rating supports repeated lightning-surge events per IEC 61000-4-5 without parametric shift. |
Applications
| USB Type-C Power Delivery Protection | Industrial Load Switch Input Protection |
|---|---|
Use Scenario: Protecting VBUS lines in USB-C receptacles supporting up to 20V/5A PD negotiation, exposed to ESD and system-level surges. IC Role / Device Role / Timing Role: Primary front-end EOS suppressor placed between connector and PD controller or load switch. Use Value: Maintains 27.5V clamping at 40A and 125°C - prevents latch-up or gate oxide rupture in 24V-tolerant PD controllers (e.g., TUSB73x, STUSB4500). |
Use Scenario: Shielding high-side load switches (e.g., HS2950P, TPS229xx) from lightning-induced transients in remote meters and robotics. IC Role / Device Role / Timing Role: Shunt protector on VIN pin to limit voltage stress on internal FET's drain-source breakdown rating. Use Value: Clamps below 28V across full temperature range - avoids exceeding 30V VDSS limits of common 30V load switches during surge events. |
| IoT Edge Node Power Bus Protection | Storage Device 22V Rail Protection |
Use Scenario: Securing 22V auxiliary rails in battery-backed IoT gateways subjected to field ESD and induced surges from nearby AC wiring. IC Role / Device Role / Timing Role: Single-device solution replacing multi-stage TVS+MOV networks for compact, reliable rail clamping. Use Value: 175pF capacitance and 600nA leakage allow use on always-on rails without standby current penalty or signal coupling. |
Use Scenario: Protecting 22V backup power inputs on NVMe SSD modules and enterprise SAS drives against hot-plug transients and chassis ESD. IC Role / Device Role / Timing Role: Low-inductance DFN-6 placement directly at edge connector to suppress fast-rising transients before reaching PMIC or flash controller. Use Value: 6-pin symmetric layout enables balanced trace routing - reduces differential-mode coupling into adjacent high-speed lanes (e.g., PCIe Gen4). |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TDS2211P | Same device - JAN1N5554 is the military-grade (JAN) variant of TDS2211P; identical electrical specs, DFN-6 package, and marking "T22". | Qualified to MIL-PRF-19500/530 for enhanced reliability screening; suitable for defense/aerospace programs requiring JAN prefix traceability. | Select JAN1N5554 when compliance with MIL-STD-883 screening, lot traceability, and extended temperature validation (–55°C to +150°C storage) is mandated. |
| uClamp2411ZA | 24V working voltage, ±30kV ESD, but lower 20A IPP rating and higher 33V clamping at 20A; SOD-323 package (higher inductance). | Targeted at CC/SBU lines in USB-C, not main VBUS; lacks constant-clamp FET architecture - clamping rises with current and temperature. | Use uClamp2411ZA only for secondary signal-line protection where 20A/33V clamping is acceptable; not a functional replacement for JAN1N5554 on 22V power rails. |
Compared with TDS2211P and uClamp2411ZA, JAN1N5554 provides identical protection performance to TDS2211P with added military qualification, while uClamp2411ZA offers lower surge capacity and non-constant clamping - making it unsuitable for primary 22V rail protection where voltage margin is constrained.

FAQ
What is the key functional difference between JAN1N5554 and standard TVS diodes?
JAN1N5554 uses a surge-rated FET with precision trigger circuitry to achieve near-constant clamping voltage (27.5–28V) across 24–40A and –40°C to +125°C, unlike standard TVS diodes whose clamping rises linearly with current and temperature. This eliminates design margin inflation and thermal derating calculations in 22V systems.
Does JAN1N5554 require a thermal pad on the PCB?
No. JAN1N5554 dissipates surge energy through the low-RDS(on) FET channel rather than PN-junction heating, so no thermal pad or copper pour is needed beneath the DFN-6 package. Layout focuses on minimizing trace inductance via short, wide connections to all six pins.
Can JAN1N5554 be used on USB 3.2 SuperSpeed differential pairs?
No. With 175pF junction capacitance, JAN1N5554 is intended for power rails and medium-speed buses (e.g., USB 2.0, SMBus). For SuperSpeed TX/RX lines, Semtech recommends RClamp3371ZC (<0.25pF) - JAN1N5554 would severely degrade signal integrity above 480 Mbps.
What does the "JAN" prefix signify for JAN1N5554?
The "JAN" prefix indicates Joint Army-Navy qualification per MIL-PRF-19500/530, including extended screening (e.g., burn-in, temperature cycling, hermeticity), tighter parameter limits, and full lot traceability - distinguishing it from commercial TDS2211P while maintaining identical electrical and mechanical specs.
How should the six pins of JAN1N5554 be routed on the PCB?
All three GND pins (1,2,3) must connect to a solid ground plane using multiple vias; all three IN pins (4,5,6) must be shorted together via a single low-inductance trace. Placement must be within 3mm of the protected connector - asymmetrical routing or floating pins degrades surge handling below 40A.
