Product details
Overview
JANTX1N6142AUS/TR from Microsemi is a voidless hermetically sealed surface-mount bidirectional Transient Voltage Suppressor (TVS) qualified to MIL-PRF-19500/516 at JANTX level. It provides 7.6 V working standoff voltage (VWM), 9.50 V minimum breakdown voltage (V(BR)) at 125 mA, and clamps transients to 14.5 V at 103.4 A peak pulse current (IPP) for 10/1000 µs waveform - deployed in avionics power bus protection and radar front-end ESD hardening.
For engineers reviewing the JANTX1N6142AUS/TR datasheet, JANTX1N6142AUS/TR pinout, JANTX1N6142AUS/TR application, or JANTX1N6142AUS/TR equivalent, key selection criteria include its 1500 W peak pulse power rating, -55°C to +175°C operating junction temperature range, Category 1 metallurgical bonds, RoHS-compliant tin/lead terminations (non-RoHS variant shown), and SQ-MELF "C" package compatibility with automated SMT placement.
Technical Context
This TVS operates bidirectionally with no polarity marking and relies on silicon avalanche breakdown to divert surge energy away from protected circuitry. Its clamping behavior is defined by a 14.5 V VC at 103.4 A IPP under 10/1000 µs waveform, with thermal resistance of 5.0 °C/W from junction to end cap.
The device uses voidless hard-glass construction with tungsten slugs and triple-layer passivation to sustain repeated transient events while maintaining stable V(BR) drift (0.07 %/°C temperature coefficient). It meets IEC61000-4-2 (ESD), IEC61000-4-4 (EFT), and select levels of IEC61000-4-5 (lightning-induced surges).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 7.6 V maximum continuous standoff voltage - defines highest DC/repetitive peak voltage before conduction begins |
| V(BR) min | 9.50 V at 125 mA - guaranteed avalanche onset threshold under standardized test current |
| VC @ IPP | 14.5 V at 103.4 A (10/1000 µs) - maximum clamped voltage seen by protected IC during worst-case surge |
| PPP | 1500 W - peak transient power handling capability without failure under standard impulse waveform |
| TJ Range | -55°C to +175°C - enables deployment in extended-temperature military platforms including missile guidance and satellite subsystems |
| RθJEC | 5.0 °C/W - thermal resistance from junction to end cap, critical for derating calculations in high-power pulse scenarios |
Pinout & Package
Package: SQ-MELF "C" (hermetically sealed voidless hard glass with tungsten slugs); terminals are square-end-cap, non-polarized, tin/lead plated copper; marking not applied; weight ≈ 1100 mg.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode | Bidirectional terminal pair | No polarity - either end serves as anode or cathode depending on transient polarity; symmetric clamping response |
| End Cap | Thermal interface | Primary heat path to PCB; requires direct thermal contact for full 1500 W pulse rating and junction temperature control |
Key Features

Applications
| Avionics Power Bus Protection | Radar Front-End Surge Hardening |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N6142US | Commercial-grade version; same electrical specs but unqualified to MIL-PRF-19500/516 | Lacks JANTX-level screening (burn-in, temp cycling, surge life); unsuitable for flight-critical systems | Select only for ground-test fixtures or non-mission-critical prototypes where cost outweighs qualification rigor |
| JANTXV1N6142AUS | Higher reliability screening per JANTXV level; tighter V(BR) distribution and enhanced surge life validation | Required for space-qualified electronics and nuclear-hardened platforms per DSCC specifications | Choose when mission assurance mandates extended lifetime prediction and zero-defect screening beyond JANTX |
Compared with JANTX1N6142AUS/TR, the commercial 1N6142US reduces procurement cost but forfeits military traceability and long-term reliability validation, while JANTXV1N6142AUS adds screening overhead for ultra-high-integrity deployments - JANTX offers optimal balance for certified airborne systems.

FAQ
What is the clamping voltage of JANTX1N6142AUS/TR under a 10/1000 µs surge?
The JANTX1N6142AUS/TR clamps to a maximum of 14.5 V when subjected to a 103.4 A peak pulse current with a 10/1000 µs waveform. This value is measured per standard test conditions in the datasheet and defines the upper voltage limit imposed on protected circuitry during transient events. The JANTX1N6142AUS/TR maintains this clamping performance across its full operating temperature range and after repeated surge exposures due to its Category 1 metallurgical bonds and voidless glass construction.
Is JANTX1N6142AUS/TR RoHS compliant?
JANTX1N6142AUS/TR is not RoHS compliant; it uses tin/lead-plated copper terminations per MIL-PRF-19500/516 requirements. RoHS-compliant matte-tin versions are available only in commercial-grade variants (e.g., 1N6142AUS), not in JANTX-qualified parts. The JANTX1N6142AUS/TR remains exempt from RoHS restrictions under military procurement allowances and is fully traceable to Microsemi's qualified manufacturing flow.
What package type does JANTX1N6142AUS/TR use?
JANTX1N6142AUS/TR uses the SQ-MELF "C" package - a hermetically sealed voidless hard-glass case with tungsten slugs and square-end-cap terminals. Dimensions are 0.183–0.202 inches in diameter and 0.205–0.245 inches in length. The JANTX1N6142AUS/TR is designed for surface-mount reflow assembly and supports EIA-481-B tape-and-reel packaging for automated placement.
How does JANTX1N6142AUS/TR differ from the non-A suffix variant 1N6142US?
The JANTX1N6142AUS/TR includes the "A" suffix indicating tighter voltage tolerances: its V(BR) minimum is 9.50 V (vs. 5% lower for non-A), VC is 5% lower, and IPP is 5% higher than 1N6142US. Additionally, JANTX1N6142AUS/TR undergoes full MIL-PRF-19500/516 screening (burn-in, temperature cycling, surge life), whereas 1N6142US is commercial-grade only. The JANTX1N6142AUS/TR also carries JANTX reliability level certification and traceable lot documentation.
Can JANTX1N6142AUS/TR be used in place of axial-leaded 1N6142 devices?
No - JANTX1N6142AUS/TR is a surface-mount SQ-MELF "C" package and is not mechanically or thermally interchangeable with axial-leaded 1N6142 variants. While both share identical electrical characteristics, the JANTX1N6142AUS/TR requires SMT reflow profiles and PCB pad layouts per Microsemi's recommended footprint. Substituting it for through-hole parts would necessitate board redesign, thermal path reassessment, and requalification per MIL-STD-780.
