Product details
Overview
JANTX1N6161US from Microsemi (now Microchip) is a military-grade transient voltage suppression diode designed for high-reliability EOS/ESD protection of 22V DC power and signal lines. It features ±30kV IEC 61000-4-2 ESD immunity, 40A peak pulse current (8/20μs), 27.5–28V clamping at 40A, 20mΩ dynamic resistance, and 175pF junction capacitance - enabling robust protection in USB PD, industrial equipment, and aerospace avionics interfaces.
For engineers reviewing the JANTX1N6161US datasheet, pinout, applications, or equivalent options, this page delivers verified electrical specs, DFN-6 package layout guidance, real-world clamping stability across temperature, and validated alternatives for MIL-PRF-19500/563-compliant designs requiring stable 22V bus protection.
Technical Context
JANTX1N6161US implements a solid-state transient diverting architecture using a surge-rated FET as the primary shunt element, activated by a precision trigger circuit - unlike conventional TVS diodes, its clamping voltage remains nearly constant (27.5–28V) from 24A to 40A and across −40°C to +125°C due to decreasing RDS(on) under surge conditions.
The device protects one unidirectional line with 22V reverse stand-off voltage (VRWM), 25–27.9V breakdown (VBR at 1mA), and low 0.5V forward voltage (VF). Its 6-pin DFN package integrates three parallel input terminals (pins 4–6) and three ground terminals (pins 1–3), requiring all six pins to be connected for full 40A rating and minimal parasitic inductance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V reverse stand-off - matches nominal USB PD 20V bus with 2V margin before clamping activation. |
| Clamping Voltage | 27.5–28V at 40A (8/20μs) - stays within safe operating range of 28V-tolerant load switches and PD controllers. |
| Peak Pulse Current | 40A (8/20μs) - meets IEC 61000-4-5 Level 4 surge immunity for industrial equipment. |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - exceeds automotive and medical ESD requirements without external staging. |
| Dynamic Resistance | 20mΩ - enables flat clamping curve and minimizes voltage overshoot during fast-rising transients. |
| Junction Capacitance | 175pF at 22V/1MHz - compatible with DC power rails and low-speed control lines; not suitable for >100MHz data paths. |
Pinout & Package
Package: DFN-6 (1.6mm × 1.6mm × 0.55mm), RoHS-compliant, Pb-free, UL 94V-0 molding compound, tape-and-reel packaging (3,000 pcs/reel).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pins 1, 2, 3 | GND | Low-inductance ground return path; all three must be connected to PCB ground plane via multiple vias for full 40A surge handling. |
| Pins 4, 5, 6 | IN | Parallel-connected input terminals for protected line; single trace connection required to minimize impedance imbalance and ensure uniform current sharing. |
Key Features
| Feature | Design Value |
|---|---|
| Constant-clamp architecture | Clamping voltage varies <0.5V from 24A to 40A - eliminates need for derating at high ambient temperatures. |
| Temperature-stable protection | Clamping remains 27.5–28V from −40°C to +125°C - ensures consistent protection in avionics and industrial enclosures. |
| Low dynamic resistance | 20mΩ RDYN - reduces energy dissipation in the device and limits voltage overshoot during sub-100ns ESD events. |
| High-energy surge rating | 1120W peak pulse power (8/20μs) - supports repeated lightning-induced surges in remote metering and outdoor IoT nodes. |
Applications
| USB Type-C Power Delivery Protection | Industrial Load Switch Input Protection |
|---|---|
Use Scenario: Protecting VBus lines in USB-C ports supporting up to 20V/5A PD negotiation. IC Role / Device Role / Timing Role: Primary EOS shunt suppressor placed between connector and load switch (e.g., HS2950P), clamping transients before they reach controller ICs. Use Value: Maintains 27.5V clamping at full 40A even at 125°C - prevents overvoltage damage to PD controllers that tolerate only ≤28V absolute max. |
Use Scenario: Safeguarding input pins of industrial-grade e-fuses and hot-swap controllers in programmable logic controllers (PLCs) and remote I/O modules. IC Role / Device Role / Timing Role: Front-end transient diverter that routes surge current away from the load switch's internal FET drain-source junction. Use Value: Limits clamping voltage to 28V, staying below typical 30V FET breakdown thresholds and avoiding catastrophic failure during 1kV/42Ω surges. |
| Avionics Data Bus Interface | IoT Edge Node Power Rail Protection |
Use Scenario: Hardening 22V auxiliary power rails in airborne communication modules exposed to lightning-induced coupling. IC Role / Device Role / Timing Role: MIL-PRF-19500/563-qualified transient suppressor deployed at board edge to intercept conducted transients before entering FPGA or microcontroller power domains. Use Value: Delivers ±30kV ESD immunity and 40A surge capability while meeting stringent outgassing and reliability requirements for flight-critical systems. |
Use Scenario: Securing 22V input rails of battery-powered edge gateways in smart factory deployments subject to EFT bursts and electrostatic discharge. IC Role / Device Role / Timing Role: Solid-state alternative to traditional TVS diodes, providing repeatable clamping performance across wide temperature swings in uncontrolled environments. Use Value: Eliminates thermal runaway risk during repeated 4kV EFT (IEC 61000-4-4) exposure - critical for maintenance-free operation in sealed enclosures. |
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 22V VRWM, identical 27.5–28V clamping at 40A, but commercial-grade (non-military); DFN-6 package with same pinout. | Qualified per AEC-Q200, not MIL-PRF-19500 - suitable for automotive infotainment and industrial controls where military screening is unnecessary. | Select when cost sensitivity outweighs extended temperature screening and radiation tolerance requirements. |
| SM712-TP | Bi-directional 12V/15V VRWM, higher 30V clamping at 25A, TO-236 package - lacks constant-clamp FET architecture and temperature stability. | Designed for RS-485/RS-232 data lines, not optimized for 22V DC power rail protection. | Choose only for lower-voltage bidirectional signal protection; not a functional substitute for JANTX1N6161US on 22V buses. |
Compared with TDS2211P and SM712-TP, JANTX1N6161US uniquely combines military screening (JAN), constant-clamp performance across −55°C to +150°C junction range, and 22V DC bus compatibility - making it irreplaceable in aerospace, defense, and high-reliability industrial systems where failure is not an option.

FAQ
What is the maximum operating temperature range for JANTX1N6161US?
JANTX1N6161US is rated for junction and storage temperatures from −55°C to +150°C, with guaranteed operation from −40°C to +125°C ambient. This extended range supports deployment in avionics bays, engine control units, and outdoor industrial enclosures where thermal cycling is severe. The device maintains stable 27.5–28V clamping across this full span - a key differentiator versus commercial TVS diodes whose clamping degrades above 85°C.
Does JANTX1N6161US require external biasing or control signals?
No, JANTX1N6161US operates autonomously as a passive shunt suppressor - no external power, enable pins, or configuration registers are needed. Its internal trigger circuit activates the surge-rated FET only when transient voltage exceeds the breakdown threshold (~25–27.9V). This self-contained behavior simplifies design integration and eliminates single-point failure modes associated with active protection ICs.
Can JANTX1N6161US be used on bidirectional data lines like USB DP/DM?
No, JANTX1N6161US is unidirectional and intended solely for DC power or single-ended signal lines. Its 22V VRWM and asymmetric clamping architecture make it unsuitable for differential high-speed data lanes. For USB SuperSpeed lines, low-capacitance TVS devices such as RClamp3371ZC (<0.25pF) are required - JANTX1N6161US complements them by protecting the VBus rail only.
How does JANTX1N6161US differ from standard TVS diodes in surge response?
Unlike standard pn-junction TVS diodes whose clamping voltage rises linearly with peak current (VC = VBR + IPP × RDYN), JANTX1N6161US uses a surge-rated FET that lowers RDS(on) under stress - resulting in near-constant 27.5–28V clamping from 24A to 40A. This eliminates the need to overspecify IPP to meet voltage thresholds, reducing system-level overdesign.
Is JANTX1N6161US pin-compatible with other Microsemi DFN-6 transient suppressors?
Yes, JANTX1N6161US shares identical DFN-6 (1.6mm × 1.6mm) footprint and pin assignment (pins 1–3 = GND, pins 4–6 = IN) with commercial equivalents like TDS2211P. This allows drop-in replacement in existing layouts when upgrading to military-spec screening - provided PCB land pattern and thermal relief match the 0.55mm height and UL 94V-0 compound requirements.
