Product details
Overview
JAN1N6169AUS/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 98.8 V working standoff voltage (VWM), 123.5 V minimum breakdown voltage (V(BR)), and 178.8 V clamping voltage (VC) at 8.4 A peak pulse current (IPP). It delivers 1500 W peak pulse power for 10/1000 µs transients and operates across –55 °C to +175 °C junction temperature range, used in military avionics power rail protection.
For engineers reviewing the JAN1N6169AUS/TR datasheet, JAN1N6169AUS/TR pinout, JAN1N6169AUS/TR application, or JAN1N6169AUS/TR equivalent, key selection criteria include its MIL-qualified reliability, bidirectional clamping behavior, glass-body thermal resistance (5.0 °C/W), and compatibility with high-energy IEC61000-4-5 lightning surge waveforms.
Technical Context
This TVS diode employs hard-glass hermetic construction with internal Category 1 metallurgical bonds, enabling radiation hardness per MicroNote 050 and immunity to ESD per MIL-STD-750 Method 1020. Its bidirectional architecture provides symmetrical clamping without polarity marking, supporting protection of AC-coupled or differential signal lines.
Designed for transient suppression in harsh environments, it sustains 1500 W peak pulse power under 10/1000 µs waveform while maintaining <5 µA standby current at VWM and linear derating above 150 °C end-cap temperature. The SQ-MELF "C" package ensures robust mechanical mounting and consistent thermal path via tungsten slugs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 98.8 V - Maximum continuous DC or repetitive peak voltage the device blocks without conduction. |
| V(BR) min | 123.5 V @ 10 mA - Minimum voltage at which the device enters avalanche breakdown, ensuring predictable turn-on margin. |
| VC @ IPP | 178.8 V @ 8.4 A - Clamped voltage during 10/1000 µs surge, defining maximum stress imposed on protected circuitry. |
| PPP | 1500 W - Peak impulse power handling capability, critical for IEC61000-4-5 Level 3–4 secondary lightning surge compliance. |
| TJ Range | –55 °C to +175 °C - Full military-grade operating junction temperature range, validated for aerospace and defense platforms. |
| RθJEC | 5.0 °C/W - Junction-to-end-cap thermal resistance, enabling direct thermal coupling to heatsink or PCB copper for sustained power dissipation. |
| αV(BR) | 0.105 %/°C - Temperature coefficient of breakdown voltage, supporting stable clamping performance across wide ambient swings. |
Pinout & Package
Package: SQ-MELF "C" (hermetically sealed voidless hard glass with tungsten slugs, square-end-cap terminals, RoHS-compliant matte-tin plating available for commercial grade only).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (bidirectional) | Transient conduction path | No polarity marking; either terminal serves as anode or cathode depending on transient polarity-enables single-device protection of AC or floating nodes. |
| End Cap (both ends) | Thermal interface & mechanical anchor | Direct thermal path to PCB or heatsink; tungsten slugs ensure low RθJEC (5.0 °C/W) and mechanical stability under shock/vibe. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled, differential, or floating bus lines without external polarity management. |
| Category 1 metallurgical bonds | Ensures long-term bond integrity under thermal cycling and mechanical stress, meeting MIL-PRF-19500/516 reliability requirements. |
| Voidless hermetic glass seal | Prevents moisture ingress and internal corrosion, eliminating failure modes common in plastic-packaged TVS devices in humid or sealed enclosures. |
| MIL-qualified JAN level | Validated for use in mission-critical systems requiring full traceability, lot control, and extended temperature operation per MIL-PRF-19500/516. |
Applications
| Avionics Power Distribution | Military Vehicle Data Buses |

IC Role / Device Role / Timing Role: Low-leakage (≤5 µA @ 98.8 V) clamping device placed before bandpass filters to prevent gate oxide rupture. Use Value: Limits clamping voltage to 178.8 V while maintaining sub-5 µA leakage, avoiding DC bias shift in sensitive analog receive paths. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N6169US | No JAN qualification; commercial-grade only, non-hermetic glass, no MIL-PRF-19500/516 compliance. | Limited to non-mission-critical industrial systems where radiation hardness and extended temperature range are not required. | Select when cost sensitivity outweighs reliability requirements and full military qualification is unnecessary. |
| JANTX1N6169AUS | Same electrical specs but JANTX-level qualification: tighter parametric screening, enhanced lot traceability, and extended temperature validation beyond JAN. | Required for programs specifying JANTX-level procurement, such as U.S. DoD prime contracts with strict reliability assurance clauses. | Choose when contract documentation mandates JANTX-level testing and reporting, not just JAN-level baseline performance. |
Compared with JAN1N6169AUS/TR, 1N6169US lacks military qualification and hermetic sealing-reducing suitability for space or naval environments-while JANTX1N6169AUS adds screening rigor without altering clamping behavior, making it preferable for high-assurance procurement where documentation depth matters more than electrical differentiation.

FAQ
What is the clamping voltage of JAN1N6169AUS/TR under a 10/1000 µs surge?
The JAN1N6169AUS/TR exhibits a maximum clamping voltage (VC) of 178.8 V when subjected to an 8.4 A peak pulse current (IPP) under the standard 10/1000 µs waveform. This value is measured and guaranteed per the manufacturer's electrical characteristics table and defines the upper voltage limit imposed on protected circuitry during surge events.
Is JAN1N6169AUS/TR suitable for bidirectional signal line protection?
Yes, JAN1N6169AUS/TR is inherently bidirectional due to its symmetrical avalanche structure and absence of polarity marking. It provides identical clamping behavior for positive and negative transients, making it appropriate for protecting AC-coupled interfaces, differential buses like MIL-STD-1553B, and floating sensor inputs without external orientation constraints.
Does JAN1N6169AUS/TR meet IEC61000-4-5 surge immunity standards?
JAN1N6169AUS/TR is rated for protection against secondary effects of lightning per select levels of IEC61000-4-5, supported by its 1500 W peak pulse power rating and 178.8 V clamping voltage. System-level compliance requires proper PCB layout, grounding, and coordination with upstream filters-but the device itself satisfies the core voltage-limiting requirement for Level 3–4 surge testing.
What is the thermal resistance specification for JAN1N6169AUS/TR?
JAN1N6169AUS/TR has a junction-to-end-cap thermal resistance (RθJEC) of 5.0 °C/W, measured under standard conditions. This low value enables efficient heat transfer from the silicon junction through the tungsten slugs to the PCB or heatsink, supporting reliable operation at elevated ambient temperatures up to +175 °C junction.
How does the JAN qualification level differ from commercial versions of JAN1N6169AUS/TR?
The JAN qualification level for JAN1N6169AUS/TR includes full compliance with MIL-PRF-19500/516, covering environmental stress screening, lot traceability, extended temperature validation (–55 °C to +175 °C), and hermeticity testing. Commercial variants lack these requirements and are not approved for use in military or space applications where failure is not tolerable.
