Product details
Overview
JANTX1N6169AUS/TR from Microsemi is a voidless hermetically sealed surface-mount bidirectional Transient Voltage Suppressor (TVS) qualified to MIL-PRF-19500/516 at JANTX level. It provides 98.8 V working peak standoff voltage (VWM), 123.5 V minimum breakdown voltage (V(BR)) at 10 mA, and clamps to 178.8 V at 8.4 A peak pulse current (IPP) for 10/1000 µs waveform - delivering 1500 W peak pulse power in high-reliability military and aerospace power rail protection.
For engineers reviewing the JANTX1N6169AUS/TR datasheet, JANTX1N6169AUS/TR pinout, JANTX1N6169AUS/TR application, or JANTX1N6169AUS/TR equivalent, key selection criteria include its MIL-qualified reliability, bidirectional clamping behavior, hard-glass hermetic package, Category 1 metallurgical bonds, and IEC61000-4-2/4-4/4-5 compliance for ESD, EFT, and lightning-induced surge immunity.
Technical Context
The JANTX1N6169AUS/TR operates as a bidirectional avalanche diode with no polarity marking, enabling symmetric transient suppression on AC lines or unidirectional rails without orientation constraints. Its hard-glass construction and internal tungsten slugs ensure thermal stability up to +175 °C junction temperature and low thermal resistance (RθJEC = 5.0 °C/W).
It delivers 1500 W peak pulse power under 10/1000 µs waveform per MIL-STD-883, with linear derating above 150 °C end-cap temperature to zero at 175 °C. Standby current remains ≤5 µA at VWM, and temperature coefficient of V(BR) is +0.105 %/°C - critical for precision overtemperature design margins.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 98.8 V - maximum continuous DC or repetitive peak reverse voltage before conduction begins; defines safe operating margin for protected circuitry. |
| V(BR) min | 123.5 V @ 10 mA - guaranteed avalanche onset threshold; ensures predictable clamping initiation under surge conditions. |
| VC @ IPP | 178.8 V @ 8.4 A - clamped voltage during 10/1000 µs surge; determines maximum stress imposed on downstream components. |
| PPP | 1500 W - peak impulse power handling capability; enables robust protection against lightning secondary effects per IEC61000-4-5. |
| TJ range | −55 to +175 °C - extended military-grade junction temperature range; supports operation in harsh environmental enclosures. |
| RθJEC | 5.0 °C/W - low junction-to-end-cap thermal resistance; allows efficient heat transfer to PCB copper or heatsink mounting points. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTX1N6168AUS/TR | Lower VWM (91.2 V), lower VC (165.1 V @ 9.1 A), same 1500 W PPP and SQ-MELF package. | Better suited for 24–48 V systems requiring tighter clamping margin below 165 V. | Select when system max operating voltage is ≤91.2 V and clamping headroom must be minimized. |
| JANTX1N6170AUS/TR | Higher VWM (114.0 V), higher VC (206.3 V @ 7.3 A), identical qualification and thermal specs. | Preferred for 100–120 V DC distribution where higher standoff avoids leakage-related power loss. | Choose when protecting 110 V nominal rails where 98.8 V VWM risks excessive standby current or premature conduction. |
Compared with JANTX1N6169AUS/TR, JANTX1N6168AUS/TR offers tighter clamping at lower voltage rails, while JANTX1N6170AUS/TR extends safe standoff for higher-voltage systems - both retain MIL-PRF-19500/516 JANTX qualification and hermetic SQ-MELF packaging but require voltage-specific layout validation.

FAQ
What is the clamping voltage of JANTX1N6169AUS/TR under standard surge conditions?
The JANTX1N6169AUS/TR clamps to 178.8 V when subjected to an 8.4 A peak pulse current (IPP) with a 10/1000 µs waveform. This value is measured per MIL-STD-883 and reflects the maximum voltage seen by protected circuitry during a standardized transient event. The clamping performance is guaranteed across the full −55 to +175 °C junction temperature range, making JANTX1N6169AUS/TR suitable for environments with extreme thermal cycling.
Is JANTX1N6169AUS/TR RoHS compliant?
No, JANTX1N6169AUS/TR is not RoHS compliant. Per the manufacturer's nomenclature and datasheet, RoHS-compliant versions (marked with "e3") are available only for commercial-grade variants of this family. The JANTX-level qualification requires tin/lead plating for enhanced solder joint reliability under thermal shock and vibration - a requirement that conflicts with RoHS lead-free mandates.
Does JANTX1N6169AUS/TR have polarity markings?
No, JANTX1N6169AUS/TR has no polarity marking because it is a bidirectional TVS diode. Its symmetrical avalanche structure allows either terminal to serve as anode or cathode depending on transient polarity. This eliminates orientation concerns during placement and simplifies layout for AC-coupled or floating circuits - a key advantage in avionics and spacecraft harness interfaces.
What is the maximum steady-state power dissipation of JANTX1N6169AUS/TR at 25 °C ambient?
JANTX1N6169AUS/TR has a maximum off-state power dissipation (PD) of 3.0 W at TA = 25 °C, decreasing linearly to zero at 150 °C end-cap temperature. This rating assumes controlled thermal resistance from mounting point to ambient - typically achieved using ≥1 in² of 2-oz copper pour per pad. Exceeding this limit risks thermal runaway even below VWM due to leakage current multiplication.
How does JANTX1N6169AUS/TR differ from commercial-grade 1N6169AUS?
JANTX1N6169AUS/TR undergoes additional screening per MIL-PRF-19500/516, including burn-in, temperature cycling, and lot acceptance testing - ensuring defect density <100 ppm and lifetime reliability >100,000 hours at rated conditions. Commercial 1N6169AUS lacks this screening and is not approved for use in safety-critical or space-qualified systems where JANTX1N6169AUS/TR is mandated.
