Product details
Overview
JANTXV1N6163AUS/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), 56.0 V working standoff voltage (VWM), and 103.1 V clamping voltage (VC) at 14.5 A peak pulse current - deployed in avionics power rail protection and radar front-end surge suppression.
For engineers reviewing the JANTXV1N6163AUS/TR datasheet, JANTXV1N6163AUS/TR pinout, JANTXV1N6163AUS/TR application, or JANTXV1N6163AUS/TR equivalent, key selection criteria include MIL-PRF-19500/516 JANTXV qualification, Category 1 metallurgical bonds, -55°C to +175°C operating range, RoHS-compliant tin/lead termination (non-RoHS standard), and 5.0°C/W junction-to-end-cap thermal resistance.
Technical Context
This TVS operates bidirectionally with no polarity marking and uses hard-glass construction with tungsten slugs for high-reliability transient suppression. Its breakdown voltage is 71.3 V at 20 mA (VBR), with temperature coefficient αV(BR) = 0.100 %/°C and standby current ≤5 µA at VWM.
It delivers 1500 W peak pulse power under 10/1000 µs waveform per MIL-STD-883, derates linearly above 150°C end-cap temperature, and features triple-layer passivation plus internal Category 1 metallurgical bonds - enabling survivability in lightning-induced secondary surges (IEC61000-4-5) and ESD events (IEC61000-4-2).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 56.0 V - maximum continuous DC or repetitive peak reverse voltage before conduction begins |
| VC @ IPP | 103.1 V at 14.5 A - clamped voltage during 10/1000 µs surge, limiting downstream stress |
| PPP | 1500 W - peak impulse power handling capability for standardized transient waveforms |
| VBR | 71.3 V @ 20 mA - measured breakdown voltage defining onset of avalanche conduction |
| TJ/TSTG | -55°C to +175°C - operational and storage temperature range supporting extended military environments |
| RθJEC | 5.0 °C/W - thermal resistance from junction to end cap, critical for pulsed power dissipation design |
| αV(BR) | 0.100 %/°C - temperature drift rate of breakdown voltage, used in thermal stability analysis |
Pinout & Package
SQ-MELF (Square-End-Cap Metal Electrode Leadless Face) surface-mount package with hermetically sealed voidless hard glass body, tungsten slugs, and tin/lead-plated copper terminals. No polarity marking due to bidirectional operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (bidirectional) | Transient conduction path | Both ends function identically as symmetrical avalanche junctions; no directional mounting required |
| End Cap (both ends) | Thermal and electrical interface | Primary heat transfer path to PCB; requires full-surface solder contact for RθJEC compliance |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional surge suppression | Enables single-device protection of AC-coupled or floating signal/power lines without polarity constraints |
| Category 1 metallurgical bonds | Guarantees mechanical integrity and bond reliability under thermal cycling and shock per MIL-PRF-19500/516 |
| Voidless hermetic seal | Prevents moisture ingress and long-term parameter drift in humid or vacuum environments |
| Triple-layer passivation | Reduces surface leakage and enhances stability of VBR and ID over lifetime and radiation exposure |
| MIL-PRF-19500/516 JANTXV qualification | Validated screening including burn-in, temperature cycling, and lot acceptance testing for high-reliability programs |
Applications
| Avionics Power Distribution | Radar RF Front-End Protection |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppressor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N6162AUS/TR | VWM = 51.7 V, VC = 97.1 V, VBR = 64.6 V - lower clamping threshold and standoff voltage | Better suited for 24–48 V systems where tighter voltage margin is required | Select when system max operating voltage is ≤51.7 V and lower clamping headroom is acceptable |
| JANTXV1N6164AUS/TR | VWM = 62.2 V, VC = 112.8 V, VBR = 77.9 V - higher standoff and clamping, same PPP rating | Preferred for 72 V nominal bus architectures or designs requiring higher VWM margin | Choose when VWM must exceed 56.0 V while retaining SQ-MELF form factor and JANTXV screening |
Compared with JANTXV1N6162AUS/TR and JANTXV1N6164AUS/TR, the JANTXV1N6163AUS/TR provides optimal balance of 56.0 V standoff and 103.1 V clamping for 28–60 V military power systems - matching common avionics and ground vehicle bus voltages without overdesigning voltage margins or sacrificing surge headroom.

FAQ
What is the clamping voltage of JANTXV1N6163AUS/TR at its rated peak pulse current?
The JANTXV1N6163AUS/TR has a maximum clamping voltage (VC) of 103.1 V at 14.5 A peak pulse current (IPP) under the standard 10/1000 µs waveform. This value is guaranteed per MIL-PRF-19500/516 test conditions and defines the upper voltage limit imposed on protected circuitry during surge events. The JANTXV1N6163AUS/TR maintains this clamping performance across its full qualified temperature range.
Is JANTXV1N6163AUS/TR RoHS compliant?
JANTXV1N6163AUS/TR is not RoHS compliant - it uses standard tin/lead termination per MIL-PRF-19500/516 requirements. RoHS-compliant matte-tin versions are available only for commercial-grade variants (e.g., 1N6163AUS without JAN/JANTXV prefix). The JANTXV1N6163AUS/TR retains leaded terminations to ensure solder joint reliability under thermal cycling and mechanical shock in military deployments.
What does the "AUS" suffix mean in JANTXV1N6163AUS/TR?
The "AUS" suffix in JANTXV1N6163AUS/TR indicates the SQ-MELF surface-mount package with square-end-cap terminals and hermetically sealed voidless glass construction. It distinguishes this variant from axial-leaded versions (e.g., 1N6163A) and confirms compliance with the mechanical and environmental specifications defined in T4-LDS-0278-1. The JANTXV1N6163AUS/TR is supplied in tape-and-reel per EIA-481-B.
How does JANTXV1N6163AUS/TR differ from commercial-grade 1N6163AUS?
JANTXV1N6163AUS/TR undergoes full MIL-PRF-19500/516 JANTXV-level screening - including extended temperature cycling, burn-in, and lot acceptance testing - whereas commercial 1N6163AUS is not screened to military standards. The JANTXV1N6163AUS/TR also features non-RoHS tin/lead plating and tighter parameter tolerances per military specification, ensuring reliability in life-critical systems where the commercial version is unsuitable.
What is the thermal resistance specification for JANTXV1N6163AUS/TR?
The JANTXV1N6163AUS/TR has a junction-to-end-cap thermal resistance (RθJEC) of 5.0 °C/W, measured under specified mounting conditions. This parameter governs how effectively heat generated during transient conduction transfers from the silicon junction to the end-cap solder interface. Proper PCB pad layout and full-surface end-cap soldering are required to achieve this rating - critical for sustaining repeated 1500 W pulses without thermal runaway.
