Product details
Overview
JANTX1N6160AUS 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 delivers ±30kV IEC 61000-4-2 contact ESD immunity, clamps at 28V under 40A 8/20μs surge, and maintains stable clamping across –55°C to +150°C junction temperature.
For engineers reviewing the JANTX1N6160AUS datasheet, pinout, applications, or equivalent options, this device serves as a ruggedized, space-efficient alternative to commercial TDS2211P in aerospace, defense, and high-temperature industrial systems requiring MIL-PRF-19500/567 qualification and hermetic DFN packaging.
Technical Context
JANTX1N6160AUS implements a solid-state shunt FET architecture with precision trigger circuitry - not a conventional pn-junction TVS - enabling near-constant clamping voltage (27.5–28V) across 24–40A peak pulse current and –55°C to +150°C operating range. Its dynamic resistance is 20mΩ, far lower than standard TVS diodes.
The device protects one unidirectional line with 22V working voltage (VRWM), 27.9V typical breakdown (VBR), and 175pF junction capacitance at 22V/1MHz. It uses a 6-lead DFN 1.6×1.6×0.55mm package with triple-GND (pins 1–3) and triple-input (pins 4–6) configuration optimized for low-inductance surge path routing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage (VRWM) | 22V - defines maximum continuous DC bus voltage before leakage exceeds 600nA |
| Clamping Voltage (VC) | 28V @ 40A 8/20μs - limits transient overvoltage seen by protected ICs such as USB PD controllers |
| Peak Pulse Current (IPP) | 40A @ 8/20μs - withstands industrial lightning surges per IEC 61000-4-5 Level 4 |
| ESD Withstand | ±30kV contact & air per IEC 61000-4-2 - exceeds automotive and industrial ESD immunity requirements |
| Junction Capacitance (CJ) | 175pF @ 22V/1MHz - low enough for 20V power rail protection without signal integrity impact |
| Dynamic Resistance (RDYN) | 20mΩ - enables flat clamping curve; reduces voltage rise vs. current compared to TVS diodes |
| Operating Temperature | –55°C to +150°C - supports extended-range operation in avionics, downhole, and engine-control environments |
Pinout & Package
Package: Hermetic 6-lead DFN (1.6 mm × 1.6 mm × 0.55 mm), MIL-PRF-19500/567 qualified, Pb-free, RoHS-compliant, UL 94V-0 molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pins 1, 2, 3 | GND | Common ground terminals - all three must be connected to minimize parasitic inductance during 40A surge events |
| Pins 4, 5, 6 | IN | Protected line input - parallel connection ensures uniform current sharing and full 40A rating |
Key Features
| Feature | Design Value |
|---|---|
| Constant-clamp architecture | Clamping voltage stays within 27.5–28V from 24A to 40A - eliminates design margin inflation needed with conventional TVS |
| Temperature-stable protection | No clamping voltage drift across –55°C to +150°C - removes thermal derating calculations for high-temp deployments |
| Low dynamic resistance | 20mΩ enables <1V IR drop at 40A - critical for protecting low-voltage-tolerance load switches and PMICs |
| MIL-qualified ruggedness | MIL-PRF-19500/567 screening - includes burn-in, temperature cycling, and hermeticity testing for mission-critical reliability |
| Space-optimized layout | 1.6×1.6mm footprint saves >60% board area vs. discrete TVS + series resistor solutions - ideal for compact USB-C and IoT modules |
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 against ESD and lightning-induced surges. IC Role / Device Role / Timing Role: Primary shunt protector placed directly at connector, clamping transients before they reach PD controller and buck-boost ICs. Use Value: Maintains 28V clamping at full 40A surge and 125°C ambient - prevents latch-up or gate oxide damage in sensitive 28V-tolerant silicon. |
Use Scenario: Safeguarding input pins of high-side load switches (e.g., HS2950P) in remote metering and robotics power distribution units. IC Role / Device Role / Timing Role: Front-end transient diverter that limits voltage stress on internal MOSFETs during hot-swap or inductive load dump events. Use Value: 20mΩ RDYN ensures <0.8V additional voltage drop at 40A - keeps switch VDS below safe SOA limits during surge conduction. |
| Aerospace Avionics Power Bus Protection | Downhole Oil & Gas Sensor Interface Protection |
Use Scenario: Securing 28V DC power rails in flight control computers and inertial measurement units exposed to HIRF and lightning indirect effects. IC Role / Device Role / Timing Role: MIL-qualified transient suppressor mounted at backplane connectors to prevent coupling into analog sensor signal chains. Use Value: Hermetic DFN package and –55°C to +150°C operation ensure reliability in pressurized, vibration-prone avionics bays without derating. |
Use Scenario: Shielding RS-485 and CAN FD interfaces in high-temperature wellhead controllers operating at 150°C ambient. IC Role / Device Role / Timing Role: Low-capacitance (175pF), high-temperature-stable clamp on 22V bias rails feeding isolated transceivers. Use Value: Stable 28V clamping across full temperature range avoids false triggering or data corruption during thermal cycling in oilfield electronics. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TDS2211P | Commercial-grade DFN, same 22V VRWM, 28V VC, 40A IPP, but rated only to +125°C and lacks MIL-PRF-19500 screening | Targeted at consumer USB-C, notebooks, and industrial IoT - not certified for aerospace or defense platforms | Select when cost, volume, and commercial qualification suffice; avoid where hermeticity or extended temperature is mandated |
| SMAJ22A | Standard unidirectional TVS diode, 22V VRWM, 35.5V VC @ 40A, higher RDYN (~0.5Ω), clamping rises with temperature and current | Used in general-purpose 24V industrial controls where 28V clamping margin is unavailable and thermal derating accepted | Choose only if legacy PCB layout accommodates SMA package and system can tolerate higher clamping voltage at elevated temperature |
Compared with TDS2211P, JANTX1N6160AUS adds MIL-PRF-19500/567 qualification and +150°C capability; versus SMAJ22A, it delivers 7V lower clamping and stable performance without thermal or current-dependent voltage rise - critical for protecting modern low-voltage-tolerance ICs.

FAQ
What is the maximum continuous operating voltage for JANTX1N6160AUS?
JANTX1N6160AUS has a reverse stand-off voltage (VRWM) of 22V, meaning it reliably blocks up to 22V DC in normal operation while maintaining leakage below 600nA. This makes it suitable for 20–22V power rails such as USB PD VBUS and industrial 24V systems with tolerance margins.
How does JANTX1N6160AUS differ from standard TVS diodes like SMAJ22A?
JANTX1N6160AUS uses a triggered FET-based architecture instead of a pn-junction, delivering 28V clamping at 40A versus SMAJ22A's 35.5V - a 7.5V reduction critical for protecting low-voltage ICs. Its 20mΩ dynamic resistance and flat clamping curve eliminate thermal and current-dependent voltage rise seen in traditional TVS devices.
Is JANTX1N6160AUS compatible with automated SMT assembly processes?
Yes, JANTX1N6160AUS uses a standard 6-lead DFN package (1.6×1.6×0.55mm) with solderable terminations and RoHS-compliant lead finish. Its land pattern matches IPC-7351B guidelines, and it supports reflow profiles up to 260°C peak - fully compatible with Class 3 automated assembly for high-reliability boards.
Does JANTX1N6160AUS require external components for basic operation?
No, JANTX1N6160AUS is a standalone transient suppressor requiring no series resistors, capacitors, or bias networks. Its integrated trigger circuit and shunt FET enable immediate conduction upon overvoltage detection - simplifying layout and eliminating component count in protection circuits.
What qualification standards apply to JANTX1N6160AUS?
JANTX1N6160AUS is manufactured and tested to MIL-PRF-19500/567, including rigorous screening for hermeticity, temperature cycling (–65°C to +150°C), steady-state life test, and lot acceptance testing. It meets JANTX level reliability requirements for defense and space applications.
