Product details
Overview
JAN1N6169US/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), 98.8 V working standoff voltage (VWM), and 178.8 V clamping voltage (VC) at 8.4 A peak pulse current - deployed in avionics power rail protection and missile guidance interface circuits.
For engineers reviewing the JAN1N6169US/TR datasheet, JAN1N6169US/TR pinout, JAN1N6169US/TR application, or JAN1N6169US/TR equivalent, this part delivers MIL-PRF-19500/516 qualified transient suppression with Category 1 metallurgical bonds, triple-layer passivation, and radiation-hardened construction suitable for high-reliability aerospace and defense systems requiring guaranteed failure immunity under lightning-induced surges and ESD events.
Technical Context
This device operates as a bidirectional avalanche diode TVS, leveraging hard-glass hermetic sealing and tungsten slug terminations to sustain junction temperatures from –55 °C to +175 °C. Its 5.0 °C/W thermal resistance (junction-to-end cap) enables stable operation under repeated 10/1000 µs transients up to 1500 W without thermal runaway.
The JAN1N6169US/TR exhibits a temperature coefficient of breakdown voltage (αVBR) of 0.105 %/°C and maintains ≤5 µA standby current at 98.8 V VWM, ensuring minimal leakage in high-impedance sensing paths while delivering precise clamping at 178.8 V under 8.4 A IPP - critical for protecting downstream FPGAs and analog front-ends in hardened platforms.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (10/1000 µs) | 1500 W - sustains single-event lightning surge energy per IEC61000-4-5 Level 3 without degradation |
| Working Standoff Voltage (VWM) | 98.8 V - maximum continuous DC or repetitive peak voltage before conduction begins |
| Clamping Voltage (VC @ IPP) | 178.8 V at 8.4 A - limits transient overvoltage to safe levels for 100 V-class logic and power ICs |
| Breakdown Voltage (VBR @ IBR) | 123.5 V at 10 mA - defines sharp avalanche onset threshold for predictable turn-on behavior |
| Standby Current (ID @ VWM) | ≤5 µA - negligible leakage in high-impedance bias networks and precision reference circuits |
| Temperature Coefficient (αVBR) | 0.105 %/°C - enables accurate thermal derating across –55 °C to +175 °C operational range |
Pinout & Package
SQ-MELF (Square-End-Cap Metal Electrode Leadless Face) hermetically sealed glass package with tungsten slugs and tin/lead-plated copper terminals; no polarity marking due to bidirectional symmetry; weight ≈1100 mg; dimensions: BD = 0.183–0.202 in (4.65–5.13 mm), BL = 0.205–0.245 in (5.21–6.22 mm).
| Pin/Terminal | Circuit Role | Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N6169AUS | Commercial-grade version; same VWM, VC, and PPP but lacks MIL-PRF-19500/516 screening and JAN-level reliability testing | Approved for non-mission-critical industrial controls; not cleared for flight hardware or nuclear C2 systems | Select only when full military qualification is unnecessary and cost sensitivity outweighs long-term reliability requirements |
| JANTXV1N6169US | Same die and package, but qualified to JANTXV level - adds extended temperature screening (–65 °C to +175 °C) and enhanced lot traceability | Required for space-qualified payloads and strategic weapons where component pedigree must include full JANTXV test records | Choose when mission assurance mandates JANTXV documentation and extended cold-start performance validation |
Compared with JAN1N6169US/TR, the commercial 1N6169AUS reduces procurement cost but forfeits MIL-qualified screening, while JANTXV1N6169US extends environmental validation at higher unit cost - enabling tiered selection based on system criticality, lifecycle duration, and audit requirements.

FAQ
What is the clamping voltage of JAN1N6169US/TR at its rated peak pulse current?
The JAN1N6169US/TR has a maximum clamping voltage (VC) of 178.8 V at 8.4 A peak pulse current (IPP) under a 10/1000 µs waveform. This value is measured per MIL-STD-750 Method 3019 and guarantees that downstream circuitry remains within safe operating limits during standardized surge events. The JAN1N6169US/TR achieves this clamping performance while maintaining tight VBR tolerance and low leakage, making it suitable for high-voltage analog and digital interfaces.
Is JAN1N6169US/TR RoHS compliant?
No, JAN1N6169US/TR is not RoHS compliant. It uses traditional tin/lead plating on copper terminals, consistent with MIL-PRF-19500/516 requirements for high-reliability solder joint integrity. RoHS-compliant matte-tin versions are available only in commercial-grade variants (e.g., 1N6169AUS), not in JAN-level parts. The JAN1N6169US/TR is intended for applications where solder joint reliability under thermal cycling and mechanical shock takes precedence over lead-free compliance.
What does the "JAN" prefix signify for JAN1N6169US/TR?
"JAN" denotes Joint Army-Navy qualification - the highest baseline reliability level under MIL-PRF-19500/516. For JAN1N6169US/TR, this includes 100% lot testing for parametric limits, burn-in, temperature cycling, and hermeticity verification. Unlike commercial or JANTX parts, JAN-level devices undergo stricter screening and are approved for use in manned aircraft, missile systems, and other applications where failure risk must be statistically bounded to less than 10−6 per hour.
Can JAN1N6169US/TR be used in bidirectional AC signal lines?
Yes, JAN1N6169US/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 ideal for protecting AC-coupled interfaces such as RS-422, MIL-STD-1553, or transformer-isolated power signals. Its SQ-MELF package allows zero-orientation placement, simplifying automated assembly in differential or floating circuits where JAN1N6169US/TR serves as a dual-quadrant voltage limiter.
What is the thermal resistance specification for JAN1N6169US/TR?
JAN1N6169US/TR has a junction-to-end-cap thermal resistance (RθJEC) of 5.0 °C/W, measured per MIL-STD-750 Method 1071. This low value enables effective heat transfer from the silicon junction to the PCB copper pads via the tungsten slugs and end-cap terminations. When mounted on ≥1 sq-in copper area, JAN1N6169US/TR supports continuous off-state power dissipation up to 5.0 W at TEC = 150 °C, with linear derating to zero at 175 °C - critical for sustained operation in enclosed avionics enclosures.
