Product details
Overview
JAN1N6141US/TR from Microsemi is a voidless hermetically sealed surface-mount bidirectional Transient Voltage Suppressor (TVS) qualified to MIL-PRF-19500/516 at JAN level, with 6.9 V working standoff voltage (VWM), 8.65 V minimum breakdown voltage (V(BR)) at 150 mA, and 13.4 V clamping voltage (VC) at 111.9 A peak pulse current (IPP) for 10/1000 µs waveform - deployed in avionics power rail protection.
For engineers reviewing the JAN1N6141US/TR datasheet, JAN1N6141US/TR pinout, JAN1N6141US/TR application, or JAN1N6141US/TR equivalent, key selection criteria include military-grade reliability (JAN qualification), bidirectional surge suppression capability, hard-glass hermetic package robustness, and IEC61000-4-2/4-4/4-5 compliance for ESD, EFT, and lightning-induced transients.
Technical Context
This TVS operates bidirectionally without polarity marking and uses internal Category 1 metallurgical bonds within a voidless hermetically sealed hard-glass package. Its clamping behavior is defined by a 10/1000 µs double-exponential pulse, delivering 1500 W peak pulse power (PPP) at 25 °C with thermal resistance junction-to-end cap of 5.0 °C/W.
The device exhibits a temperature coefficient of breakdown voltage (αV(BR)) of 0.06 %/°C and supports operation across –55 °C to +175 °C junction temperature range. Standby current ID is ≤100 µA at rated VWM, and it maintains stable clamping performance under repetitive impulse conditions up to 0.01% duty cycle.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.9 V - maximum continuous DC or repetitive peak voltage the device blocks without conduction |
| V(BR) min | 8.65 V @ 150 mA - guaranteed breakdown onset threshold under specified test current |
| VC @ IPP | 13.4 V @ 111.9 A - clamped voltage during 10/1000 µs transient, limiting downstream circuit stress |
| PPP | 1500 W @ 25 °C - peak transient energy absorption capacity for standardized surge waveform |
| TJ Range | –55 °C to +175 °C - operational junction temperature envelope supporting extreme-environment deployment |
| αV(BR) | 0.06 %/°C - predictable V(BR) drift over temperature, enabling accurate system-level margining |
| ID @ VWM | ≤100 µA - low leakage ensures minimal standby power loss in always-on systems |
Pinout & Package

| End Cap (both ends) | Thermal interface / mechanical anchor | Direct thermal path to PCB pad; RθJEC = 5.0 °C/W enables high-power dissipation without heatsink |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N6141US/TR | Commercial-grade version; no JAN qualification; same electrical specs and package | Lacks MIL-PRF-19500/516 screening and traceability; not suitable for defense procurement | Select when full JAN reliability is unnecessary and cost sensitivity dominates |
| JANTX1N6141US/TR | Higher screening level (JANTX); tighter parametric limits and extended environmental testing | Required for programs demanding enhanced burn-in, life test, and lot traceability beyond JAN | Select when system-level reliability targets exceed JAN baseline, e.g., mission-critical flight hardware |
Compared with JAN1N6141US/TR, the commercial 1N6141US/TR offers identical clamping performance but omits military screening, while JANTX1N6141US/TR adds process controls and test rigor - enabling tiered reliability selection without layout or schematic change.

FAQ
What is the clamping voltage of JAN1N6141US/TR under a 10/1000 µs surge?
The clamping voltage (VC) of JAN1N6141US/TR is 13.4 V when subjected to a 10/1000 µs transient pulse at its rated peak pulse current of 111.9 A. This value is measured per standard test conditions defined in MIL-PRF-19500/516 and ensures downstream circuitry remains within safe operating voltage limits during surge events. The JAN1N6141US/TR maintains this clamping performance across its full operating temperature range.
Is JAN1N6141US/TR RoHS compliant?
No, JAN1N6141US/TR is not RoHS compliant. It uses tin/lead-plated copper terminals per MIL-PRF-19500/516 requirements for military-grade reliability. RoHS-compliant matte-tin plating is available only on commercial-grade versions (e.g., 1N6141US/TR), not on JAN-level devices. The JAN1N6141US/TR conforms to legacy exemption 7a for high-reliability military applications.
What does the "JAN" prefix signify for JAN1N6141US/TR?
"JAN" denotes Joint Army-Navy qualification under MIL-PRF-19500/516, indicating that JAN1N6141US/TR has undergone rigorous screening including temperature cycling, hermeticity testing, and lot acceptance testing. This prefix certifies that the JAN1N6141US/TR meets baseline military reliability standards for use in defense and aerospace systems where failure is not acceptable.
Can JAN1N6141US/TR be used in bidirectional signal line protection?
Yes, JAN1N6141US/TR is inherently bidirectional and requires no polarity marking, making it suitable for protecting AC-coupled or floating DC signal paths such as RS-485 buses or sensor bridges. Its symmetrical V-I characteristics ensure consistent clamping in both directions, and its low standby current (≤100 µA at 6.9 V) avoids loading sensitive analog nodes. The JAN1N6141US/TR delivers this functionality in a compact SQ-MELF package.
What is the maximum junction temperature rating for JAN1N6141US/TR?
The maximum junction temperature (TJ) rating for JAN1N6141US/TR is +175 °C, with a minimum of –55 °C. This wide operating range supports deployment in extreme environments such as engine bays, space-based power systems, and high-temperature industrial controls. Thermal resistance junction-to-end cap is 5.0 °C/W, enabling effective heat transfer to the PCB without additional heatsinking - a critical design advantage for the JAN1N6141US/TR in constrained layouts.
