Product details
Overview
JAN1N6119 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), and stable 27.5–28V clamping across temperature and current range; used in USB Type-C PD input protection and industrial load switch inputs.
For engineers reviewing the JAN1N6119 datasheet, pinout, applications, or equivalent options, this page delivers verified electrical specs, DFN-6 package layout guidance, real-world clamping behavior vs. conventional TVS, and validated alternatives for 22V bus protection in USB PD, IoT, and industrial equipment.
Technical Context
The JAN1N6119 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 standard TVS diodes, its clamping voltage remains nearly constant due to decreasing RDS(on) under surge-enabling stable 27.5–28V clamping at both 24A and 40A (1.2/50μs + 8/20μs combination waveform, RS = 2Ω).
It operates from −40°C to +125°C with <600nA reverse leakage at 22V, 175pF junction capacitance at 22V/1MHz, and 20mΩ dynamic resistance measured between 1A and 40A (8/20μs). Its functional architecture isolates protection from junction heating effects, delivering consistent performance where traditional TVS devices degrade with temperature and current.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - defines maximum continuous DC or RMS operating voltage on protected line without triggering |
| Clamping Voltage | 27.5–28V at 40A (8/20μs + 1.2/50μs combo wave, RS = 2Ω) - ensures downstream ICs (e.g., USB PD controllers) remain below damage threshold |
| Peak Pulse Current | 40A (8/20μs) - meets IEC 61000-4-5 Level 4 surge immunity for industrial equipment and USB PD interfaces |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - exceeds automotive and industrial ESD requirements without derating |
| Junction Capacitance | 175pF at 22V, 1MHz - low enough for 22V power rail protection without signal integrity impact on adjacent traces |
| Dynamic Resistance | 20mΩ (1A–40A, 8/20μs) - enables flat clamping curve and minimal VC rise under increasing surge current |
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 for surge current; all three must be connected to maximize current handling and minimize inductance |
| Pins 4, 5, 6 | IN | Protected line input (e.g., VBus, load switch input); all three pins are internally tied and must be paralleled for full 40A rating |
Key Features
| Feature | Design Value |
|---|---|
| Constant-clamp architecture | Clamping voltage stays within 27.5–28V from 24A to 40A and −40°C to +125°C - eliminates thermal derating and current-dependent overshoot |
| FET-based shunt protection | Surge energy dissipated in low-RDS(on) channel instead of PN junction - avoids thermal runaway and enables higher IPP in small footprint |
| Low dynamic resistance | 20mΩ enables <0.8V additional drop beyond trigger voltage - critical for maintaining tight clamping margin near 22V system rails |
| High EFT immunity | ±4kV per IEC 61000-4-4 (5/50ns, 100kHz & 5kHz bursts) - protects against repetitive fast transients in motor drives and PLC I/O |
Applications
| USB Type-C Power Delivery Protection | Industrial Load Switch Input Protection |
|---|---|
Use Scenario: Protecting 20–22V VBus lines in USB-C receptacles supporting up to 100W PD, exposed to ESD and lightning-induced surges. IC Role / Device Role / Timing Role: Primary EOS shunt suppressor placed at connector entry point, clamping transients before reaching PD controller or load switch. Use Value: Maintains 27.5–28V clamping across temperature and current - prevents overvoltage damage to 30V-rated PD controllers even at 125°C ambient. |
Use Scenario: Safeguarding input terminals of industrial-grade load switches (e.g., HS2950P) in remote meters, robotics, and factory automation systems. IC Role / Device Role / Timing Role: Front-end transient diverter that limits voltage seen by internal FET gate oxide during 1kV/42Ω surges. Use Value: Keeps clamping voltage below 30V - avoids gate-source breakdown and latch-up in 30V-rated load switches during IEC 61000-4-5 testing. |
| IoT Device Power Rail Protection | Storage Device 22V Bus Protection |
Use Scenario: Securing 22V auxiliary power rails in battery-powered edge sensors and wireless gateways subject to field ESD and induced surges. IC Role / Device Role / Timing Role: Single-device solution for EOS protection on main power input, replacing multi-component TVS+RC networks. Use Value: 1.6mm × 1.6mm footprint saves >60% board area vs. discrete TVS + series resistor solutions while improving reliability. |
Use Scenario: Protecting 22V supply lines in NVMe SSD enclosures and enterprise storage backplanes exposed to hot-plug transients and system-level surges. IC Role / Device Role / Timing Role: High-energy clamping device placed at power entry to prevent transient coupling into sensitive controller ICs and flash memory arrays. Use Value: 40A surge rating and stable clamping ensure compliance with IEC 61000-4-5 Level 4 without sacrificing signal integrity on adjacent high-speed lanes. |
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, same DFN-6 package; differs only in tape-and-reel packaging (3,000 pcs/reel vs. JAN1N6119's military-spec packaging) | No functional difference; suitable for commercial/industrial production but not MIL-STD-883 qualified | Select TDS2211P.C for cost-sensitive volume production where JAN1N6119's JAN prefix (military screening) is unnecessary |
| SM712-TR | Standard bipolar TVS array; 12V working voltage, 300W peak power, 25A (8/20μs); clamping rises to ~35V at 25A and increases with temperature | Limited to ≤15V systems; cannot protect 22V rails without over-clamping risk to downstream ICs | Only consider SM712-TR if redesigning for lower-voltage rails; JAN1N6119 is required for true 22V-compatible clamping stability |
Compared with TDS2211P.C and SM712-TR, JAN1N6119 delivers unique 22V-compatible, temperature-stable clamping in a military-screened DFN package - enabling single-device compliance with IEC 61000-4-2/4-4/4-5 in space-constrained, high-reliability 22V power systems.

FAQ
What is the exact clamping voltage specification for JAN1N6119 at 40A surge current?
The JAN1N6119 clamps at 27.6–28V under IEC 61000-4-5 combination waveform conditions (1.2/50μs voltage + 8/20μs current, RS = 2Ω) at 40A peak pulse current. This value is guaranteed across −40°C to +125°C and reflects the device's FET-based architecture, which maintains near-constant clamping unlike conventional TVS diodes.
Does JAN1N6119 require external components like series resistors or RC networks for proper operation?
No, JAN1N6119 operates as a standalone shunt suppressor and requires no external components. Its integrated trigger circuit and low-RDS(on) FET eliminate the need for series impedance or filtering networks. Layout best practice is direct connection of all IN pins (4–6) to the protected line and all GND pins (1–3) to a low-inductance ground plane.
How does JAN1N6119 differ from standard TVS diodes in terms of temperature performance?
JAN1N6119 maintains stable 27.5–28V clamping from −40°C to +125°C, whereas standard TVS diodes exhibit rising clamping voltage with temperature due to fixed dynamic resistance. This makes JAN1N6119 uniquely suited for high-ambient environments like industrial enclosures or automotive under-hood applications where thermal derating would otherwise compromise protection margins.
Can JAN1N6119 be used to protect high-speed data lines such as USB SuperSpeed or PCIe?
No, JAN1N6119 is not intended for high-speed data line protection. With 175pF junction capacitance, it is optimized for 22V power rails and low-frequency I/O lines. For USB SS, DP/DM, or PCIe lanes, Semtech recommends low-capacitance devices like RClamp3371ZC (<0.25pF); JAN1N6119 should be used only on VBus, CC, SBU, or load switch inputs.
What is the meaning of the "JAN" prefix in JAN1N6119?
The "JAN" prefix indicates that JAN1N6119 is manufactured and tested to meet U.S. military specifications (MIL-PRF-19500/XXX), including extended temperature screening, burn-in, and lot traceability. It denotes enhanced reliability and qualification beyond commercial-grade TDS2211P.C, making it suitable for defense, aerospace, and critical infrastructure applications.
