Product details
Overview
JANTX1N6170AUS/TR from Microsemi is a voidless hermetically sealed surface-mount bidirectional Transient Voltage Suppressor (TVS) qualified to MIL-PRF-19500/516 at JANTX level. It provides 114.0 V working peak standoff voltage (VWM), 206.3 V clamping voltage (VC) at 7.3 A peak pulse current (IPP), and 1500 W peak pulse power for 10/1000 µs waveform - deployed in high-reliability military avionics power rail protection.
For engineers reviewing the JANTX1N6170AUS/TR datasheet, JANTX1N6170AUS/TR pinout, JANTX1N6170AUS/TR application, or JANTX1N6170AUS/TR equivalent, key selection criteria include its MIL-qualified bidirectional clamping behavior, hard-glass hermetic package, Category 1 metallurgical bonds, and IEC61000-4-5 lightning secondary-effect compliance.
Technical Context
This TVS operates bidirectionally with no polarity marking and uses triple-layer passivation on a voidless hermetically sealed hard-glass case with tungsten slugs. Its breakdown voltage is 142.5 V at 8 mA (V(BR)), with temperature coefficient αV(BR) of 0.105 %/°C and junction-to-end-cap thermal resistance RθJEC of 5.0 °C/W.
It delivers 1500 W peak pulse power under 10/1000 µs waveform while maintaining ≤5 µA standby current (ID) at VWM, and supports operation from –55 °C to +175 °C junction temperature. The device is RoHS-compliant only in commercial-grade versions; JANTX1N6170AUS/TR is non-RoHS per MIL specification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 114.0 V - maximum continuous reverse/forward voltage before clamping initiates |
| V(BR) | 142.5 V @ 8 mA - guaranteed minimum breakdown voltage threshold |
| VC | 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 |

Applications
| Avionics Power Bus Protection | Military Vehicle DC Distribution |
|---|---|
Use Scenario: 28 V DC primary bus in fighter jet subsystems exposed to load dump and EMP transients.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTX1N6169AUS | VWM = 98.8 V, VC = 178.8 V @ 8.4 A - lower clamping voltage but reduced standoff margin | Better suited for 28 V systems with tighter VWM headroom; less margin for 115 V AC-derived rails | Select when clamping voltage priority outweighs standoff voltage requirement |
| JANTX1N6171AUS | VWM = 121.6 V, VC = 218.4 V @ 6.9 A - higher standoff but elevated clamping | Preferred for 270 V DC systems needing >120 V continuous rating; trades clamping performance for voltage margin | Choose when system nominal voltage exceeds 114 V and transient energy remains ≤1500 W |
Compared with JANTX1N6170AUS/TR, JANTX1N6169AUS offers lower clamping at reduced standoff, while JANTX1N6171AUS extends voltage margin at higher clamping - enabling precise trade-off selection based on system VIN range and maximum tolerable transient excursion.

FAQ
What is the clamping voltage of JANTX1N6170AUS/TR under standard test conditions?
The JANTX1N6170AUS/TR has a maximum clamping voltage (VC) of 206.3 V when subjected to a 10/1000 µs surge waveform at 7.3 A peak pulse current (IPP). This value is measured per MIL-STD-750 Method 3013 and defines the upper voltage limit imposed on protected circuitry during transient events. The JANTX1N6170AUS/TR maintains this clamping performance across its full operating temperature range of –55 °C to +175 °C.
Is JANTX1N6170AUS/TR RoHS compliant?
No, JANTX1N6170AUS/TR is not RoHS compliant. Per the manufacturer's documentation, RoHS-compliant versions (marked with "e3") are available only for commercial-grade variants of the 1N6138AUS–1N6173AUS family. The JANTX1N6170AUS/TR is a military-qualified part built to MIL-PRF-19500/516 specifications and uses tin/lead plating on copper terminals, consistent with legacy defense procurement requirements.
What package type does JANTX1N6170AUS/TR use, and how is it mounted?
JANTX1N6170AUS/TR uses the SQ-MELF ("C") surface-mount package - a voidless hermetically sealed hard-glass case with square-end-cap terminals. It is designed for reflow soldering onto PCB pads per EIA-481-B tape-and-reel format. Mounting requires direct solder attachment to copper pads; adhesive bonding is optional and may use a centered 2.29 mm diameter spot if needed per package drawing notes.
How does JANTX1N6170AUS/TR differ from the non-A version (e.g., JANTX1N6170US)?
The "A" suffix in JANTX1N6170AUS/TR denotes tighter electrical tolerances: minimum V(BR) is 5% higher, VC is 5% lower, and IPP is 5% higher than the base part (e.g., JANTX1N6170US). This results in more predictable clamping behavior and improved surge margin. The JANTX1N6170AUS/TR also features enhanced process controls per MIL-PRF-19500/516 JANTX screening, whereas non-A versions lack these tolerances and qualification levels.
Does JANTX1N6170AUS/TR require polarity-aware layout on the PCB?
No, JANTX1N6170AUS/TR does not require polarity-aware layout. As a bidirectional TVS, it has no anode/cathode designation and is marked with no polarity indicators. Either end functions identically under positive or negative transients, simplifying PCB routing and eliminating orientation errors during automated placement. This symmetry is confirmed in the nomenclature section and mechanical drawings of the T4-LDS-0278-1 datasheet for JANTX1N6170AUS/TR.
