Overview
JAN1N6166US/TR from Microsemi is a voidless hermetically sealed, bidirectional Transient Voltage Suppressor (TVS) qualified to MIL-PRF-19500/516 at JAN reliability level. It provides 76.0 V working standoff voltage (VWM), 95.0 V minimum breakdown voltage (V(BR)) at 12 mA, and clamps transients to 137.6 V at 10.9 A (10/1000 µs pulse), delivering 1500 W peak pulse power for high-reliability aerospace and defense power rail protection.
For engineers reviewing the JAN1N6166US/TR datasheet, JAN1N6166US/TR pinout, JAN1N6166US/TR application, or JAN1N6166US/TR equivalent, this military-grade TVS offers verified ESD/EFT/IEC61000-4-5 secondary lightning protection, Category 1 metallurgical bonds, triple-layer passivation, and RoHS-compliant tin-lead terminations - critical for mission-critical transient suppression in harsh-environment electronics.
Technical Context
This device operates as a bidirectional clamping TVS with no polarity marking, designed for symmetric surge suppression on AC lines or unidirectional rails where reverse polarity events must be tolerated. Its hard-glass hermetic package enables operation from −55 °C to +175 °C junction temperature, with thermal resistance of 5.0 °C/W from junction to end cap.
It delivers 1500 W peak pulse power under 10/1000 µs waveform per MIL-STD-750 Method 2072, with 0.100 %/°C temperature coefficient of breakdown voltage and <5 µA standby current at VWM - ensuring stable clamping behavior across wide temperature excursions in avionics and satellite power systems.

FAQ
What is the clamping voltage of JAN1N6166US/TR under a 10/1000 µs surge?
The JAN1N6166US/TR clamps to a maximum of 137.6 V when subjected to a 10.9 A peak pulse current with a 10/1000 µs waveform. This value is measured per MIL-STD-750 Method 2072 and defines the upper voltage limit imposed on protected circuitry during transient events. The clamping performance is guaranteed across the full −55 °C to +175 °C junction temperature range, and the JAN1N6166US/TR maintains this specification after full MIL-PRF-19500/516 JAN-level qualification screening.
Is JAN1N6166US/TR RoHS compliant?
No, the JAN1N6166US/TR uses standard tin/lead (SnPb) plating on its copper terminals, as required for military-grade solderability and reliability under thermal cycling. RoHS-compliant matte-tin versions are only available in commercial-grade variants (e.g., 1N6166AUS), not in JAN-qualified parts. The JAN1N6166US/TR complies with MIL-PRF-19500/516 mechanical and electrical requirements, and its SnPb finish ensures proven joint integrity in high-reliability reflow profiles.
What does the "US" suffix mean in JAN1N6166US/TR?
The "US" suffix in JAN1N6166US/TR denotes the SQ-MELF surface-mount package configuration - a voidless hermetically sealed glass body with square-end-cap terminals optimized for automated placement and high-reliability solder joints. It distinguishes this version from axial-leaded variants (e.g., JAN1N6166) and confirms compliance with Microsemi's T4-LDS-0278-1 packaging specification. The "TR" indicates tape-and-reel packaging per EIA-481-B standards.
How does JAN1N6166US/TR differ from the "A" version (e.g., JAN1N6166AUS)?
The JAN1N6166US/TR has tighter electrical tolerances than non-"A" versions: its minimum breakdown voltage is 95.0 V (vs. 5% lower for non-A), clamping voltage is 137.6 V (vs. 5% higher for non-A), and peak pulse current is 10.9 A (vs. 5% lower for non-A). These tighter specs ensure more predictable clamping margins in safety-critical designs. The JAN1N6166US/TR is fully specified in Microsemi's T4-LDS-0278-1 Rev. 2 datasheet and qualifies to the same JAN reliability level as the "A" variant.
Can JAN1N6166US/TR be used in place of JAN1N6166?
No - JAN1N6166US/TR and JAN1N6166 are not interchangeable. JAN1N6166 is an axial-leaded through-hole device with different mechanical form factor, thermal path, and mounting requirements. The JAN1N6166US/TR is SQ-MELF surface-mount only, with square-end-cap terminals and optimized thermal resistance (5.0 °C/W junction-to-end-cap). Substituting between packages requires PCB redesign, thermal validation, and requalification per MIL-PRF-19500/516 - the JAN1N6166US/TR must be selected explicitly for SMT-based high-reliability layouts.
