Product details
Overview
JAN1N6164US/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 62.2 V working standoff voltage (VWM), 77.9 V minimum breakdown voltage (V(BR)), and 112.8 V clamping voltage (VC) at 13.3 A peak pulse current (IPP), used for lightning surge and ESD protection in military avionics power rails.
For engineers reviewing the JAN1N6164US/TR datasheet, JAN1N6164US/TR pinout, JAN1N6164US/TR application, or JAN1N6164US/TR equivalent, key selection criteria include standoff voltage margin, clamping ratio, peak pulse power rating, temperature coefficient of V(BR), and MIL-spec qualification level for high-reliability deployment.
Technical Context
This device operates as a bidirectional avalanche diode TVS, leveraging hard-glass hermetic construction with Category 1 metallurgical bonds to sustain 1500 W peak pulse power (10/1000 µs) without degradation. Its VWM of 62.2 V ensures stable blocking up to rated DC voltage while maintaining low standby current (≤5 µA).
The junction-to-end-cap thermal resistance is 5.0 °C/W, enabling effective heat dissipation during transient events, and its temperature coefficient of breakdown voltage is +0.100 %/°C - critical for predicting V(BR) drift across –55 °C to +175 °C operating range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 62.2 V - maximum continuous reverse voltage before conduction begins; sets safe operating margin for protected circuitry. |
| V(BR) min | 77.9 V @ 15 mA - guaranteed avalanche onset threshold; defines minimum overvoltage triggering point. |
| VC @ IPP | 112.8 V @ 13.3 A - clamped voltage during 10/1000 µs surge; determines worst-case stress on downstream components. |
| PPP | 1500 W - peak pulse power handling capability; validates robustness against IEC61000-4-5 lightning surges. |
| αV(BR) | +0.100 %/°C - predictable V(BR) increase with temperature; enables accurate derating in high-ambient environments. |
| TJ/TSTG | –55 °C to +175 °C - extended military-grade junction/storage temperature range; supports operation in harsh aerospace enclosures. |
Pinout & Package
Package: SQ-MELF (C package), voidless hermetically sealed hard glass with tungsten slugs; terminals are tin/lead plated copper; polarity not marked due to bidirectional symmetry.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bidirectional avalanche junction | No polarity marking required; either end functions identically as transient clamp path in AC or DC lines. |
| End Cap (both ends) | Thermal and electrical termination | Provides mechanical mounting interface and primary heat path to PCB; RθJEC = 5.0 °C/W measured to end cap. |
Key Features
| Feature | Design Value |
|---|---|
| Voidless hermetic glass seal | Eliminates internal voids that cause moisture ingress or bond fatigue under thermal cycling - essential for 20+ year field life in satellites. |
| Category 1 metallurgical bonds | Guarantees bond integrity under shock/vibration per MIL-STD-883; prevents interfacial delamination during repeated surge events. |
| MIL-PRF-19500/516 JAN qualification | Validated screening includes burn-in, temperature cycling, and lot acceptance testing - required for DoD procurement in flight-critical systems. |
| Triple-layer passivation | Protects silicon surface from contamination and ion migration during long-term bias stress in humid, high-voltage environments. |
Applications
| Aerospace Power Distribution | Military Radar Front-End |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N6164AUS | Same electrical specs but commercial-grade (non-MIL); no JAN qualification screening or temperature cycling test data. | Lacks MIL-PRF-19500/516 compliance; unsuitable for DoD contracts requiring traceable reliability data. | Select only for cost-sensitive non-military prototypes where full MIL screening is unnecessary. |
| JANTX1N6164US | Identical SQ-MELF package and electrical parameters; differs only in JANTX-level screening (more rigorous than JAN, less than JANS). | Approved for higher-reliability programs requiring enhanced lot traceability and extended burn-in, e.g., airborne mission computers. | Choose when system-level reliability requirements exceed JAN but do not mandate full JANS radiation hardness or extreme temp cycling. |
Compared with JAN1N6164US/TR, 1N6164AUS offers identical performance at lower cost but no military qualification, while JANTX1N6164US provides tighter process controls and broader environmental validation - making it preferable for mission-critical platforms where failure risk must be minimized beyond baseline JAN requirements.

FAQ
What is the clamping voltage of JAN1N6164US/TR and how is it verified?
The clamping voltage (VC) of JAN1N6164US/TR is 112.8 V measured at 13.3 A peak pulse current (IPP) under 10/1000 µs waveform conditions per MIL-STD-750 Method 3013. This value is confirmed in the official Microsemi T4-LDS-0278-1 datasheet, Page 3, Electrical Characteristics table. The VC specification ensures downstream components experience no more than 112.8 V during standardized surge events, and JAN1N6164US/TR maintains this performance across its full operating temperature range.
Is JAN1N6164US/TR RoHS compliant?
No, JAN1N6164US/TR is not RoHS compliant. Per the Microsemi datasheet (Page 2, Features section), RoHS-compliant versions (marked with "e3") are available only for commercial-grade variants, not for JAN-level qualified parts like JAN1N6164US/TR. The JAN1N6164US/TR uses standard tin/lead plating on copper terminals, consistent with legacy military specifications requiring Pb-based finishes for solder joint reliability under thermal cycling.
What is the meaning of "JAN" in JAN1N6164US/TR?
"JAN" denotes Joint Army-Navy qualification per MIL-PRF-19500/516, indicating that JAN1N6164US/TR has undergone full military screening including temperature cycling, burn-in, and lot acceptance testing. It is the baseline military reliability level - less rigorous than JANTX or JANS but sufficient for many DoD applications. The "JAN" prefix confirms JAN1N6164US/TR meets the minimum screening requirements for use in defense electronics where failure cannot be tolerated.
Does JAN1N6164US/TR have polarity markings?
No, JAN1N6164US/TR does not have polarity markings because it is a bidirectional TVS device. As stated in the Microsemi datasheet (Page 2, Mechanical and Packaging section), "Polarity: No polarity marking for these bidirectional TVSs." Both ends of the SQ-MELF package function identically as symmetrical avalanche junctions, allowing flexible placement on PCBs without orientation constraints - a key advantage for protecting AC-coupled or differential signal paths.
What is the thermal resistance of JAN1N6164US/TR and how does it affect layout?
JAN1N6164US/TR has a junction-to-end-cap thermal resistance (RθJEC) of 5.0 °C/W, as specified in the Maximum Ratings table (Page 1). This means each watt of transient power dissipated raises the junction temperature by 5 °C above the end-cap temperature. For optimal thermal performance, PCB pads must provide low-impedance thermal paths to copper planes, and the end caps must be soldered to thermally robust land patterns per the recommended pad layout on Page 7 - critical for sustaining repeated 1500 W surges without exceeding the +175 °C max junction temperature.
