Product details
Overview
JANTXV1N6170AUS/TR from Microsemi is a military-qualified, voidless hermetically sealed surface-mount bidirectional Transient Voltage Suppressor (TVS) designed for high-reliability circuit protection. It features a 114.0 V working standoff voltage (VWM), 206.3 V clamping voltage (VC) at 7.3 A peak pulse current (IPP), and 1500 W peak pulse power (PPP) for 10/1000 µs waveform - deployed in aerospace power conditioning and avionics interface protection.
For engineers reviewing the JANTXV1N6170AUS/TR datasheet, JANTXV1N6170AUS/TR pinout, JANTXV1N6170AUS/TR application, or JANTXV1N6170AUS/TR equivalent, key selection criteria include MIL-PRF-19500/516 JANTXV qualification level, bidirectional clamping behavior, glass-body thermal resistance (5.0 °C/W), and IEC61000-4-2/4-4/4-5 compliance for ESD, EFT, and lightning surge immunity.
Technical Context
This TVS operates as a bidirectional voltage-clamping device with no polarity marking, leveraging hard-glass construction and Category 1 metallurgical bonds to sustain repeated 1500 W transients. Its breakdown voltage is 142.5 V at 8 mA test current, with temperature coefficient αV(BR) of 0.105 %/°C - enabling predictable derating across –55 °C to +175 °C junction range.
It delivers 7.3 A peak pulse current at 206.3 V clamping under 10/1000 µs waveform, with standby leakage ≤5 µA at 114.0 V standoff. Thermal resistance from junction to end cap is 5.0 °C/W, supporting stable operation up to 150 °C end-cap temperature before linear derating to zero at 175 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 114.0 V - maximum continuous reverse standoff voltage before conduction begins |
| V(BR) | 142.5 V @ 8 mA - guaranteed minimum breakdown voltage threshold |
| VC @ IPP | 206.3 V @ 7.3 A - clamped voltage during 10/1000 µs surge, limiting downstream stress |
| PPP | 1500 W - peak transient energy absorption capability per single impulse |
| TJ Range | –55 °C to +175 °C - qualified operating junction temperature for MIL-grade reliability |
| RθJEC | 5.0 °C/W - thermal resistance from junction to end cap, critical for power dissipation design |
| ID @ VWM | ≤5 µA - ultra-low leakage ensures minimal standby power loss in high-impedance circuits |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N6169AUS | Lower VWM (98.8 V), lower VC (178.8 V), higher IPP (8.4 A) | Better suited for 100 V nominal systems with tighter clamping margin | Select when system max operating voltage is ≤100 V and lower clamping voltage is prioritized |
| JANTXV1N6171AUS | Higher VWM (121.6 V), higher VC (218.4 V), lower IPP (6.9 A) | Optimized for 120 V+ systems requiring higher standoff with relaxed surge current demand | Select when nominal rail is ≥120 V and peak surge energy remains within 1500 W limit |
Compared with JANTXV1N6170AUS/TR, JANTXV1N6169AUS offers tighter clamping at lower voltage but reduced standoff headroom, while JANTXV1N6171AUS extends standoff capability at the cost of higher clamping - choice depends on system nominal voltage, margin to trip, and worst-case surge profile.

FAQ
What is the clamping voltage of JANTXV1N6170AUS/TR under standard 10/1000 µs surge conditions?
The JANTXV1N6170AUS/TR has a maximum clamping voltage (VC) of 206.3 V when subjected to its rated peak pulse current of 7.3 A under the 10/1000 µs waveform. This value is guaranteed per the manufacturer's electrical characteristics table and defines the upper voltage limit imposed on protected circuitry during transient events.
Is JANTXV1N6170AUS/TR RoHS compliant?
No, JANTXV1N6170AUS/TR is not RoHS compliant. Per the datasheet nomenclature and features section, RoHS-compliant (e3) versions are available only for commercial-grade variants - JANTXV-level parts use traditional tin/lead plating and are exempt from RoHS requirements per MIL-PRF-19500/516 qualification protocols.
What does the "AUS" suffix indicate in JANTXV1N6170AUS/TR?
The "AUS" suffix in JANTXV1N6170AUS/TR denotes the SQ-MELF surface-mount package configuration with voidless hermetic glass construction. It distinguishes this variant from axial-leaded ("C") versions and confirms compliance with the mechanical and packaging specifications defined in T4-LDS-0278-1 Rev. 2.
How is thermal performance characterized for JANTXV1N6170AUS/TR?
JANTXV1N6170AUS/TR specifies a thermal resistance of 5.0 °C/W from junction to end cap (RθJEC). This parameter enables direct calculation of junction temperature rise during pulse events and supports steady-state derating per Figure 4 and Figure 5 in the datasheet - critical for ensuring long-term reliability in high-ambient environments.
Does JANTXV1N6170AUS/TR require polarity-aware PCB layout?
No, JANTXV1N6170AUS/TR does not require polarity-aware layout. As a bidirectional TVS, it has no anode/cathode designation - both terminals are functionally identical, and the device clamps symmetrically for positive or negative transients. The datasheet explicitly states "No polarity marking for these bidirectional TVSs."
