Product details
Overview
JANTX1N6140AUS/TR from Microsemi is a voidless hermetically sealed surface-mount bidirectional Transient Voltage Suppressor (TVS) qualified to MIL-PRF-19500/516 at JANTX reliability level. It provides 6.2 V working standoff voltage (VWM), 7.79 V minimum breakdown voltage (V(BR)) at 150 mA, and clamps transients to 12.1 V at 124 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 JANTX1N6140AUS/TR datasheet, JANTX1N6140AUS/TR pinout, JANTX1N6140AUS/TR application, or JANTX1N6140AUS/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 (e3), and SQ-MELF "C" package compatibility with automated SMT placement.
Technical Context
This TVS operates bidirectionally with no polarity marking and delivers robust transient suppression via hard-glass construction and internal tungsten-slug thermal path. Its 5.0 °C/W junction-to-end-cap thermal resistance enables stable 1500 W pulse handling under controlled mounting conditions.
The device meets IEC61000-4-2 (ESD), IEC61000-4-4 (EFT), and select IEC61000-4-5 (lightning surge) immunity requirements. It exhibits 0.06 %/°C temperature coefficient of breakdown voltage and maintains <100 µA standby current at rated VWM.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.2 V - Maximum continuous reverse-biased voltage before conduction begins; sets system-level overvoltage threshold for protected circuitry. |
| V(BR) min | 7.79 V @ 150 mA - Confirmed breakdown onset point; ensures reliable triggering above normal operating voltage with margin. |
| VC @ IPP | 12.1 V @ 124 A - Clamping voltage during 10/1000 µs surge; defines worst-case voltage seen by downstream ICs during transient events. |
| PPP | 1500 W - Peak pulse power capability; supports high-energy lightning-induced surges in military-grade platforms. |
| TJ Range | -55 °C to +175 °C - Full military temperature range; validated for engine bay, radar transmitter, and space-qualified electronics. |
| RθJEC | 5.0 °C/W - Junction-to-end-cap thermal resistance; enables direct thermal coupling to heatsinked PCB copper or chassis mounts. |
| αV(BR) | 0.06 %/°C - Low temperature drift of breakdown voltage; maintains consistent clamping performance across extreme ambient shifts. |
Pinout & Package
Package: SQ-MELF "C" (hermetically sealed voidless hard glass with tungsten slugs); terminals are tin/lead plated copper; no polarity marking; weight ≈ 1100 mg.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (bidirectional) | Transient current path | Both ends function identically; symmetric conduction enables AC line or differential signal protection without orientation constraints. |
| End cap (glass body contact) | Thermal interface | Primary heat dissipation path; requires direct thermal contact with copper pour or metal chassis for full 1500 W pulse rating. |
Key Features
| Feature | Design Value |
|---|---|
| Voidless hermetic seal | Eliminates internal moisture ingress and long-term parameter drift; required for 20+ year field life in sealed avionics enclosures. |
| Category 1 metallurgical bonds | Ensures mechanical integrity under shock/vibration (MIL-STD-810G) and thermal cycling (MIL-STD-202G); prevents bond lift during repeated surge events. |
| Triple-layer passivation | Protects PN junction from contamination during reflow soldering and harsh environmental exposure (salt fog, humidity). |
| JANTX qualification | Validated per MIL-PRF-19500/516 screening including burn-in, temperature cycling, and lot acceptance testing - mandatory for DoD procurement. |
Applications
| Aerospace Power Distribution | Ground Vehicle Radar Front-End |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N6140US/TR | Commercial-grade version; lacks MIL-PRF-19500/516 qualification; same electrical specs but no JANTX screening or temperature range validation. | Not approved for DoD, NASA, or FAA-certified platforms; suitable only for non-military industrial prototypes. | Select only if full military qualification is unnecessary and cost sensitivity outweighs long-term reliability requirements. |
| JANTXV1N6140AUS/TR | JANTXV qualification adds extended temperature screening (-65 °C to +175 °C), enhanced lot traceability, and tighter parametric limits per MIL-PRF-19500/516. | Required for spaceflight, nuclear command systems, and high-reliability missile guidance where single-point failure is unacceptable. | Choose when mission-critical operation demands highest-tier screening beyond standard JANTX level. |
Compared with JANTX1N6140AUS/TR, the commercial 1N6140US/TR omits military screening and temperature validation, while JANTXV1N6140AUS/TR extends low-temperature capability and traceability - both share identical VWM, VC, and PPP but differ in qualification scope and supply-chain assurance.

FAQ
What is the maximum clamping voltage of the JANTX1N6140AUS/TR during a 10/1000 µs surge?
The JANTX1N6140AUS/TR clamps to a maximum of 12.1 V when subjected to a 124 A peak pulse current with a 10/1000 µs waveform. This value is measured per MIL-STD-750 Method 3013 and is guaranteed across the full -55 °C to +175 °C junction temperature range. The JANTX1N6140AUS/TR achieves this clamping performance while maintaining bidirectional symmetry and hermetic reliability.
Is the JANTX1N6140AUS/TR RoHS compliant?
The JANTX1N6140AUS/TR uses tin/lead (SnPb) terminations and is not RoHS compliant; RoHS-compliant matte-tin versions are available only in commercial-grade variants (e.g., 1N6140AUS/TR with e3 suffix). The JANTX1N6140AUS/TR retains SnPb for proven solder joint reliability under thermal cycling and mechanical shock per MIL-STD-883.
What package type does the JANTX1N6140AUS/TR use, and how is it mounted?
The JANTX1N6140AUS/TR uses the SQ-MELF "C" package - a voidless hermetically sealed hard-glass cylinder with tungsten slugs and square-end-cap terminals. It is surface-mounted using standard reflow profiles (peak 260 °C for 10 s) and requires thermal contact between end caps and PCB copper or chassis for full 1500 W pulse rating. No polarity orientation is needed due to bidirectional symmetry.
How does the JANTX1N6140AUS/TR differ from the JANTXV version?
The JANTXV1N6140AUS/TR undergoes additional screening per MIL-PRF-19500/516, including extended temperature range validation (-65 °C to +175 °C), enhanced lot traceability, and tighter parametric limits on V(BR) and VC. The JANTX1N6140AUS/TR meets standard JANTX requirements but lacks the extended low-temperature qualification and stricter test coverage of the JANTXV variant.
Can the JANTX1N6140AUS/TR be used in AC signal line protection?
Yes - the JANTX1N6140AUS/TR is inherently bidirectional and has no polarity marking, making it suitable for AC-coupled signal lines such as RS-485, CAN bus physical layers, or transformer-isolated Ethernet interfaces. Its 6.2 V VWM and 12.1 V VC ensure safe clamping of common-mode transients without interfering with normal signal swing in balanced differential systems.
