Product details
Overview
JAN1N6165US/TR from Microsemi is a military-qualified, voidless hermetically sealed bidirectional Transient Voltage Suppressor (TVS) in SQ-MELF (C) package, rated for 1500 W peak pulse power (10/1000 µs), 69.2 V working standoff voltage (VWM), and 125.1 V clamping voltage (VC) at 12 A peak pulse current - deployed in avionics power bus protection and radar front-end surge suppression.
For engineers reviewing the JAN1N6165US/TR datasheet, JAN1N6165US/TR pinout, JAN1N6165US/TR application, or JAN1N6165US/TR equivalent, this part delivers MIL-PRF-19500/516 qualified transient suppression with Category 1 metallurgical bonds, triple-layer passivation, and radiation-hardened glass construction for high-reliability defense electronics where failure is not an option.
Technical Context
This TVS operates bidirectionally without polarity marking and maintains stable clamping performance across -55 °C to +175 °C junction temperature range. Its hard-glass hermetic seal eliminates internal voids, and tungsten slug construction ensures low thermal resistance (RθJEC = 5.0 °C/W) for reliable energy dissipation during repetitive transients.
The device complies with IEC61000-4-2 (ESD), IEC61000-4-4 (EFT), and select levels of IEC61000-4-5 (lightning-induced surges). It exhibits a temperature coefficient of breakdown voltage (αV(BR)) of 0.100 %/°C and is non-sensitive to ESD per MIL-STD-750 Method 1020.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N6165AUS | Same electrical specs but commercial-grade, non-military qualified; lacks MIL-PRF-19500/516 screening and Category 1 bonds | Not suitable for flight-critical or JANS/JANTXV-requiring programs; acceptable for ground-test benches and non-safety-critical subsystems | Select only when full military qualification is not mandated and cost sensitivity outweighs long-term reliability requirements |
| JAN1N6164US/TR | Lower VWM (62.2 V) and VC (112.8 V); 13.3 A IPP; otherwise identical package, qualification, and construction | Better suited for 56 V nominal systems (e.g., naval 48 V DC grids) where tighter clamping margin is required below 115 V | Choose when system operating voltage is lower and clamping headroom must be minimized without sacrificing surge rating |
Compared with 1N6165AUS and JAN1N6164US/TR, the JAN1N6165US/TR uniquely combines 69.2 V standoff, 125.1 V clamping, and full JAN-level qualification - making it the only option for mission-critical 28–70 V military platforms requiring guaranteed surge survival and radiation tolerance.

FAQ
What is the clamping voltage of JAN1N6165US/TR at its rated peak pulse current?
The JAN1N6165US/TR has a maximum clamping voltage (VC) of 125.1 V at 12 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 clamping performance remains stable across its full operating temperature range (-55 °C to +175 °C), making JAN1N6165US/TR suitable for extreme-environment applications where voltage overshoot must be tightly bounded.
Is JAN1N6165US/TR RoHS compliant?
No, JAN1N6165US/TR is not RoHS compliant. As a JAN-level military-qualified part, it uses tin/lead-plated copper terminations per MIL-PRF-19500/516 requirements. RoHS-compliant matte-tin versions are available only for commercial-grade variants (e.g., 1N6165AUS), not for JAN, JANTX, JANTXV, or JANS reliability levels. The JAN1N6165US/TR retains lead content to ensure solder joint reliability under thermal cycling and mechanical shock - a requirement validated in its qualification testing.
What does the "US" suffix indicate in JAN1N6165US/TR?
The "US" suffix in JAN1N6165US/TR denotes the SQ-MELF (C) surface-mount package - a voidless hermetically sealed hard-glass case with square-end-cap terminals. This distinguishes it from axial-leaded versions (e.g., JAN1N6165US without "/TR", or non-suffix parts like 1N6165). The "/TR" indicates tape-and-reel packaging per EIA-481-B. The JAN1N6165US/TR thus specifies both military qualification (JAN), package type (US), and packaging format (TR) - all critical for procurement and assembly traceability in defense contracts.
How does JAN1N6165US/TR differ from JAN1N6165US (without /TR)?
JAN1N6165US/TR and JAN1N6165US share identical electrical specifications, military qualification (JAN level), and SQ-MELF package construction. The sole difference is packaging format: "/TR" indicates tape-and-reel delivery per EIA-481-B for automated SMT placement, whereas JAN1N6165US is supplied in bulk or ammo-pack formats. Both parts have the same 125.1 V clamping voltage and 69.2 V working standoff voltage, and either may be used interchangeably in design - provided the assembly process matches the packaging format.
Can JAN1N6165US/TR be used in place of JAN1N6166US/TR?
JAN1N6165US/TR is not a direct replacement for JAN1N6166US/TR due to differing electrical parameters: JAN1N6165US/TR has VWM = 69.2 V and VC = 125.1 V, while JAN1N6166US/TR has VWM = 76.0 V and VC = 137.6 V. Substituting them requires verifying that the higher clamping voltage of JAN1N6166US/TR does not exceed downstream component ratings, and that the 76.0 V standoff aligns with system operating margins. The JAN1N6165US/TR remains optimal for 70 V-class systems needing tighter clamping headroom.
