Product details
Overview
JAN1N6167AUS/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), 86.6 V working standoff voltage (VWM), and 151.3 V clamping voltage (VC) at 9.9 A peak pulse current. It operates across –55 °C to +175 °C and is used in high-reliability avionics power bus protection.
For engineers reviewing the JAN1N6167AUS/TR datasheet, JAN1N6167AUS/TR pinout, JAN1N6167AUS/TR application, or JAN1N6167AUS/TR equivalent, key selection criteria include its MIL-PRF-19500/516 JAN-level qualification, bidirectional clamping behavior, hard-glass construction with Category 1 metallurgical bonds, and compliance with IEC61000-4-2/4-4/4-5 transient immunity standards.
Technical Context
This TVS diode employs a silicon avalanche junction structure optimized for fast response (<1 ns) to ESD and lightning-induced transients. Its bidirectional symmetry enables protection of AC-coupled or floating signal/power lines without polarity concerns.
The device uses tungsten slugs and triple-layer passivation within a voidless hermetic glass enclosure, ensuring long-term stability under thermal cycling and radiation exposure per MicroNote 050. Thermal resistance junction-to-end cap is 5.0 °C/W, supporting robust power dissipation in constrained aerospace PCB layouts.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N6167US | No JAN-level qualification; commercial grade only; same VWM, VC, and PPP but lacks MIL-PRF-19500/516 screening. | Not suitable for flight-critical or space-qualified designs requiring traceable lot testing and extended temperature validation. | Select when cost sensitivity outweighs mission-critical reliability requirements and RoHS compliance is mandatory. |
| JANTXV1N6167AUS | Higher screening level (JANTXV) includes additional temperature cycling, hermeticity testing, and lot acceptance per MIL-PRF-19500/516. | Required for systems demanding enhanced burn-in and failure analysis traceability beyond baseline JAN requirements. | Choose for strategic defense platforms where component pedigree and failure mode documentation are contractually mandated. |
Compared with JAN1N6167AUS/TR, 1N6167US offers identical electrical specs but no military screening, while JANTXV1N6167AUS adds rigorous environmental validation-making the JAN version the optimal balance of proven reliability and procurement accessibility for Tier-1 aerospace integrators.

FAQ
What is the clamping voltage of JAN1N6167AUS/TR at its rated peak pulse current?
The JAN1N6167AUS/TR has a maximum clamping voltage (VC) of 151.3 V at 9.9 A peak pulse current (IPP) under 10/1000 µs waveform conditions. This value defines the upper voltage limit imposed on protected circuitry during surge events and is guaranteed across the full operating temperature range of –55 °C to +175 °C per the T4-LDS-0278-1 datasheet.
Is JAN1N6167AUS/TR suitable for bidirectional AC line protection?
Yes, JAN1N6167AUS/TR is inherently bidirectional due to its symmetrical avalanche junction structure and absence of polarity marking. It provides equal clamping performance for positive and negative transients, making it appropriate for protecting AC-coupled data lines, transformer-isolated power supplies, and floating sensor interfaces where voltage reversal occurs.
Does JAN1N6167AUS/TR require special PCB layout considerations?
Yes-JAN1N6167AUS/TR demands low-inductance mounting: use wide, short copper traces to minimize lead inductance, ensure full-surface solder wetting on both end caps per EIA-481-B, and avoid thermal relief patterns that impede heat transfer. Its RθJEC of 5.0 °C/W relies on direct thermal contact to the PCB for effective surge energy dissipation.
What is the standoff voltage rating of JAN1N6167AUS/TR and how does it relate to system operating voltage?
JAN1N6167AUS/TR has a rated working standoff voltage (VWM) of 86.6 V DC. This means it remains non-conductive up to this voltage under normal operation; system nominal voltage must be ≤80% of VWM (e.g., ≤69 V for 28 V systems with margin) to prevent leakage current and ensure reliable transient response without false triggering.
How does JAN1N6167AUS/TR comply with electromagnetic immunity standards?
JAN1N6167AUS/TR meets IEC61000-4-2 (ESD ±8 kV contact), IEC61000-4-4 (EFT ±2 kV), and select levels of IEC61000-4-5 (lightning surge) due to its 1500 W peak pulse power rating and sub-nanosecond response time. Its hard-glass construction and Category 1 bonds maintain performance stability across repeated stress events without parameter drift.
