Overview
JANTXV1N6142AUS/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), 7.6 V working standoff voltage (VWM), and 14.5 V clamping voltage (VC) at 103.4 A peak pulse current - deployed in avionics power rail protection and radar front-end ESD hardening.
For engineers reviewing the JANTXV1N6142AUS/TR datasheet, JANTXV1N6142AUS/TR pinout, JANTXV1N6142AUS/TR application, or JANTXV1N6142AUS/TR equivalent, key selection criteria include MIL-PRF-19500/516 JANTXV qualification level, bidirectional clamping behavior, glass-body thermal resistance (5.0 °C/W), and compatibility with high-reliability PCB assembly under 260 °C reflow.
Technical Context
This TVS operates bidirectionally with no polarity marking and uses Category 1 internal metallurgical bonds for radiation-hardened reliability per MicroNote 050. Its hard-glass construction ensures voidless hermetic sealing, enabling operation from −55 °C to +175 °C junction temperature.
It delivers 1500 W peak pulse power under 10/1000 µs waveform while maintaining 100 µA maximum standby current at 7.6 V VWM, and exhibits 0.07 %/°C temperature coefficient of breakdown voltage - critical for stable clamping across extended thermal environments in aerospace systems.
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 |
|---|---|---|---|
| 1N6142US | Commercial-grade version; lacks JANTXV screening, 100% lot testing, and extended temperature validation. | Not approved for DoD or NASA Class B/C programs; limited to non-safety-critical industrial controls. | Select only when full MIL-PRF-19500/516 compliance is not required and cost sensitivity outweighs long-term reliability needs. |
| JANTXV1N6141AUS/TR | Lower VWM (6.9 V) and VC (13.4 V); 111.9 A IPP; identical package and qualification level. | Better suited for 24 V systems where tighter clamping margin is needed; slightly reduced surge headroom. | Choose when system VWM tolerance requires <7.0 V standoff or when lower clamping voltage improves downstream IC margin. |
Compared with JANTXV1N6142AUS/TR, the commercial 1N6142US sacrifices military screening and temperature validation for cost reduction, while JANTXV1N6141AUS/TR trades 0.7 V higher VWM for 1.1 V lower clamping - enabling finer voltage-margin tuning in 24–28 V platforms without changing board layout or qualification status.

FAQ
What is the maximum clamping voltage of JANTXV1N6142AUS/TR under a 10/1000 µs surge?
The JANTXV1N6142AUS/TR has a maximum clamping voltage (VC) of 14.5 V when subjected to its rated peak pulse current of 103.4 A under the standard 10/1000 µs waveform. This value is measured per MIL-STD-750 Method 3013 and guarantees consistent overvoltage limiting across all JANTXV-screened lots. The JANTXV1N6142AUS/TR maintains this clamping performance from −55 °C to +125 °C ambient.
Is JANTXV1N6142AUS/TR RoHS compliant?
No, JANTXV1N6142AUS/TR is not RoHS compliant. It uses tin/lead terminal plating per MIL-PRF-19500/516 requirements and is intended for high-reliability military applications where leaded finishes ensure superior solder joint integrity and thermal fatigue resistance. RoHS-compliant versions (e.g., with matte-tin plating) are available only in commercial-grade variants like 1N6142AUS, not in JANTXV-qualified parts.
What does the "A" suffix in JANTXV1N6142AUS/TR signify?
The "A" suffix in JANTXV1N6142AUS/TR indicates standard voltage tolerance: minimum breakdown voltage (VBR) of 9.50 V at 125 mA test current, versus non-A parts which have 5% lower VBR, 5% higher VC, and 5% lower IPP. This ensures tighter parametric control for precision clamping applications. The JANTXV1N6142AUS/TR meets all electrical specifications listed in Microsemi T4-LDS-0278-1 Rev. 2.
Can JANTXV1N6142AUS/TR be used in surface-mount reflow processes?
Yes, JANTXV1N6142AUS/TR supports standard leaded reflow profiles with a maximum solder temperature of 260 °C for 10 seconds, as specified in MIL-STD-202 Method 210. Its SQ-MELF glass package withstands thermal shock without cracking or seal degradation. The JANTXV1N6142AUS/TR must be mounted using tin/lead solder paste and verified per IPC-J-STD-001 Class 3 requirements for high-reliability assemblies.
How does JANTXV1N6142AUS/TR differ from commercial 1N6142AUS in reliability testing?
JANTXV1N6142AUS/TR undergoes full MIL-PRF-19500/516 screening including 100% lot acceptance testing, burn-in at 150 °C for 168 hours, and temperature cycling from −65 °C to +150 °C for 500 cycles - none of which apply to commercial 1N6142AUS. The JANTXV1N6142AUS/TR also carries full traceability to wafer lot and assembly batch, meeting DoD AS9100 and NASA EEE-INST-002 requirements.
