Product details
Overview
JANTXV1N6170US/TR from Microsemi is a military-qualified, voidless hermetically sealed bidirectional Transient Voltage Suppressor (TVS) in SQ-MELF package, rated for 1500 W peak pulse power (10/1000 µs), 114.0 V working standoff voltage (VWM), and 206.3 V clamping voltage (VC) at 7.3 A peak pulse current. It operates across –55 °C to +175 °C and is used in high-reliability avionics power rail protection.
For engineers reviewing the JANTXV1N6170US/TR datasheet, JANTXV1N6170US/TR pinout, JANTXV1N6170US/TR application, or JANTXV1N6170US/TR equivalent, key selection criteria include its MIL-PRF-19500/516 JANTXV qualification, Category 1 metallurgical bonds, 5.0 °C/W junction-to-end-cap thermal resistance, and IEC61000-4-2/4-4/4-5 compliance for ESD, EFT, and lightning-induced surge immunity.
Technical Context
This TVS diode employs a hard-glass, voidless hermetic construction with tungsten slugs and triple-layer passivation to ensure robustness under repeated high-energy transients. Its bidirectional architecture provides symmetrical clamping without polarity marking, enabling direct placement across unidirectional or AC-coupled signal/power lines.
The device delivers 1500 W peak pulse power at 10/1000 µs waveform with a temperature coefficient of breakdown voltage (αVBR) of 0.105 %/°C and a maximum standby current of 5 µA at VWM, supporting stable operation in wide-temperature military environments where failure is not tolerable.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 114.0 V - Maximum continuous DC or repetitive peak voltage the device blocks without conduction. |
| VC @ IPP | 206.3 V at 7.3 A - Clamped voltage during 10/1000 µs surge, defining worst-case overvoltage seen by protected circuitry. |
| PPP | 1500 W - Peak transient energy handling capability, critical for lightning secondary-effect suppression per IEC61000-4-5. |
| TJ/TSTG | –55 °C to +175 °C - Full military temperature range support, validated for aerospace and defense platforms. |
| RθJEC | 5.0 °C/W - Low thermal resistance enables efficient heat transfer to PCB end-cap mounting points under sustained surge duty. |
| ID @ VWM | 5 µA - Ultra-low leakage ensures minimal power loss and no interference with high-impedance sensing circuits. |
| αVBR | 0.105 %/°C - Predictable VBR drift over temperature, essential for precision clamping in thermally variable enclosures. |
Pinout & Package
Package: SQ-MELF (Square-End-Cap Metal Electrode Leadless Face), hermetically sealed voidless hard glass with tungsten slugs; terminals are tin/lead plated copper; no polarity marking due to bidirectional symmetry.

FAQ
What is the clamping voltage of JANTXV1N6170US/TR at its rated peak pulse current?
The JANTXV1N6170US/TR has a maximum clamping voltage (VC) of 206.3 V at 7.3 A peak pulse current (IPP) under the standard 10/1000 µs waveform. This value is measured per MIL-PRF-19500/516 test conditions and defines the upper voltage limit imposed on protected circuitry during surge events. The JANTXV1N6170US/TR maintains this clamping performance across its full operating temperature range.
Is JANTXV1N6170US/TR RoHS compliant?
No, JANTXV1N6170US/TR is not RoHS compliant. Per the manufacturer's nomenclature and datasheet, RoHS-compliant versions (marked with "e3") are available only for commercial-grade variants-not for JAN, JANTX, JANTXV, or JANS qualified parts like JANTXV1N6170US/TR. The JANTXV1N6170US/TR uses tin/lead plating per MIL-PRF-19500/516 requirements.
What package type does JANTXV1N6170US/TR use, and how is it mounted?
JANTXV1N6170US/TR uses the SQ-MELF (Square-End-Cap Metal Electrode Leadless Face) package-a hermetically sealed voidless hard-glass case with tungsten slugs. It is surface-mounted using end-cap soldering to PCB pads; thermal performance depends on direct metal contact between the glass body ends and copper pads, achieving RθJEC = 5.0 °C/W. No polarity orientation is required due to bidirectional symmetry.
Does JANTXV1N6170US/TR require derating above ambient temperature?
Yes, JANTXV1N6170US/TR requires derating for steady-state power dissipation above 25 °C ambient, per Figure 5 in the datasheet. Its off-state power rating drops linearly from 3.0 W at 25 °C to zero at 150 °C. For pulsed operation, peak pulse power remains at 1500 W up to TJ = 175 °C, but thermal management must ensure junction temperature stays within limits during repetitive surges.
How does JANTXV1N6170US/TR differ from commercial-grade 1N6170AUS?
JANTXV1N6170US/TR is a JANTXV-level military-qualified variant with enhanced screening-including extended temperature cycling, burn-in, and surge life testing per MIL-PRF-19500/516-while commercial 1N6170AUS lacks this qualification. Both share identical electrical specs (VWM = 114.0 V, VC = 206.3 V), but JANTXV1N6170US/TR guarantees performance in harsh environments where commercial parts are not permitted.
