Product details
Overview
JAN1N6161AUS/TR from Microsemi is a voidless hermetically sealed, bidirectional Transient Voltage Suppressor (TVS) qualified to MIL-PRF-19500/516 at JAN level. It provides 47.1 V working standoff voltage (VWM), 58.9 V minimum breakdown voltage (V(BR)), 85.3 V clamping voltage (VC) at 17.6 A peak pulse current (IPP), and 1500 W peak pulse power for 10/1000 µs waveform - deployed in high-reliability military avionics power rail protection.
For engineers reviewing the JAN1N6161AUS/TR datasheet, JAN1N6161AUS/TR pinout, JAN1N6161AUS/TR application, or JAN1N6161AUS/TR equivalent, key selection criteria include its MIL-qualified reliability level, bidirectional clamping behavior, glass-body thermal resistance (5.0 °C/W), standoff-to-clamp voltage margin (ΔV = 38.2 V), and compatibility with EIA-481-B tape-and-reel handling.
Technical Context
This device operates as a bidirectional avalanche diode TVS, leveraging hard-glass encapsulation and Category 1 metallurgical bonds to sustain surge events without degradation. Its clamping response is defined by a 10/1000 µs double-exponential pulse, with thermal derating linear from 150 °C to zero at 175 °C junction temperature.
The JAN1N6161AUS/TR exhibits no polarity marking due to symmetrical bidirectional conduction, and its standoff voltage (47.1 V) is rated for continuous DC or repetitive peak cathode-to-anode bias. Standby leakage remains ≤5 µA at VWM, and temperature coefficient of V(BR) is +0.100 %/°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 47.1 V - maximum continuous reverse-bias voltage before clamping onset; defines safe operating window for protected circuitry. |
| V(BR) min | 58.9 V @ 20 mA - guaranteed avalanche initiation threshold; ensures predictable turn-on under transient overvoltage. |
| VC @ IPP | 85.3 V @ 17.6 A - clamped voltage during 10/1000 µs surge; determines worst-case stress on downstream components. |
| PPP | 1500 W - peak impulse power handling capacity; supports IEC61000-4-5 lightning-induced surge immunity testing. |
| RθJEC | 5.0 °C/W - junction-to-end-cap thermal resistance; enables direct heatsinking via end-cap mounting for sustained power dissipation. |
| TJ/TSTG | –55 to +175 °C - operational and storage temperature range; validated for extended-life deployment in aerospace and defense platforms. |
| αV(BR) | +0.100 %/°C - positive temperature coefficient ensures stable breakdown voltage across wide ambient ranges. |
Pinout & Package
Package: SQ-MELF (C package), hermetically sealed voidless hard glass with tungsten slugs; square-end-cap terminals for automated placement; weight ≈1100 mg; dimensions per Microsemi T4-LDS-0278-1 Rev. 2 (Page 7).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (bidirectional) | Surge current path | No polarity marking; symmetric conduction allows installation without orientation check; both ends serve identical clamping function. |
| End Cap (both ends) | Thermal interface | Directly bonded tungsten slug enables low-impedance heat transfer to PCB copper or heatsink; critical for thermal management above 5 W steady-state. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled or floating signal/power lines without polarity constraints. |
| Category 1 metallurgical bonds | Guarantees bond integrity under mechanical shock, vibration, and thermal cycling per MIL-PRF-19500/516. |
| Voidless hermetic seal | Prevents moisture ingress and internal corrosion over 20+ year field life in humid or salt-laden environments. |
| MIL-PRF-19500/516 qualification | JAN-level screening includes lot acceptance tests, burn-in, and parametric verification - required for DoD procurement. |
| Triple-layer passivation | Reduces surface leakage and enhances long-term stability of V(BR) and ID under high-humidity bias conditions. |
Applications
| Avionics Power Distribution | Military Vehicle ECUs |
|---|---|

IC Role / Device Role / Timing Role: Fast-response bidirectional suppressor placed before DC-DC converter and PA bias rails. Use Value: Square-end-cap geometry enables precise pick-and-place alignment; hermetic seal prevents outgassing in vacuum-sealed enclosures. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N6161AUS (commercial) | No JAN-level screening; lacks MIL-PRF-19500/516 qualification; same electrical specs and package. | Not approved for DoD or space programs requiring JAN reliability level; suitable for industrial prototypes. | Select only when MIL-spec compliance is not mandated and cost sensitivity outweighs lifetime assurance. |
| JAN1N6160AUS/TR | Lower VWM (42.6 V), lower VC (77.0 V), higher IPP (19.5 A); otherwise identical construction and qualification. | Better suited for 36 V nominal systems where tighter clamping margin is required. | Choose when system operating voltage is ≤36 V and lower clamping voltage improves downstream component safety margin. |
Compared with JAN1N6161AUS/TR, the commercial 1N6161AUS omits military screening but retains full electrical equivalence, while JAN1N6160AUS/TR offers improved clamping performance at reduced standoff - enabling optimized trade-offs between voltage headroom and surge robustness in 28–48 V platforms.

FAQ
What does the "JAN" prefix signify for JAN1N6161AUS/TR?
The "JAN" prefix indicates that JAN1N6161AUS/TR is manufactured and tested to the highest reliability level under MIL-PRF-19500/516, including rigorous lot acceptance testing, burn-in, and parametric verification. This qualification is mandatory for U.S. Department of Defense procurement and ensures proven performance in extreme environments - a distinction not shared by commercial-grade variants like 1N6161AUS.
Is JAN1N6161AUS/TR bidirectional, and how does that affect circuit layout?
Yes, JAN1N6161AUS/TR is inherently bidirectional due to its symmetrical avalanche structure and absence of polarity marking. This eliminates orientation constraints during placement - both terminals function identically as anode/cathode depending on transient polarity. Layout requires no directional routing, simplifying PCB design for AC-coupled or floating interfaces where polarity reversal may occur.
What is the thermal management requirement for JAN1N6161AUS/TR in continuous operation?
JAN1N6161AUS/TR has a junction-to-end-cap thermal resistance of 5.0 °C/W. For steady-state power dissipation up to its 5.0 W rating (at TEC = 150 °C), end-cap soldering to thermally robust PCB copper or external heatsinks is essential. Derating is linear to zero at 175 °C, so thermal design must ensure end-cap temperature stays below 150 °C under worst-case ambient and power conditions.
How does JAN1N6161AUS/TR meet IEC61000-4-5 lightning surge requirements?
JAN1N6161AUS/TR delivers 1500 W peak pulse power for the standardized 10/1000 µs waveform defined in IEC61000-4-5, with a clamping voltage of 85.3 V at 17.6 A. This performance enables it to protect downstream 50 V-rated components during Level 3 (2 kV line-earth) and Level 4 (4 kV line-earth) tests when properly coordinated with impedance-matching filters and grounding strategies.
Can JAN1N6161AUS/TR be used in RoHS-compliant assemblies?
No - JAN1N6161AUS/TR uses tin/lead plating per MIL-PRF-19500/516 requirements and is not RoHS compliant. RoHS-compliant matte-tin termination is available only on commercial-grade versions (e.g., 1N6161AUS) and is explicitly excluded from JAN-level parts to maintain proven reliability under thermal and mechanical stress.
