Product details
Overview
JANTX1N6164AUS/TR from Microsemi is a military-qualified, voidless hermetically sealed bidirectional Transient Voltage Suppressor (TVS) in SQ-MELF "C" package, rated for 1500 W peak pulse power (10/1000 µs), 62.2 V working standoff voltage (VWM), and 112.8 V clamping voltage (VC) at 13.3 A peak pulse current. It operates across –55 °C to +175 °C and is used in high-reliability avionics power rail protection.
For engineers reviewing the JANTX1N6164AUS/TR datasheet, JANTX1N6164AUS/TR pinout, JANTX1N6164AUS/TR application, or JANTX1N6164AUS/TR equivalent, key selection criteria include its MIL-PRF-19500/516 qualification level (JANTX), bidirectional clamping behavior, glass-body thermal resistance (5.0 °C/W), and IEC61000-4-2/4-4/4-5 compliance for ESD, EFT, and lightning-induced surge immunity.
Technical Context
This device functions as a voltage-clamped shunt protector with symmetrical breakdown in both polarities, enabling robust transient suppression on unidirectional or AC-coupled signal/power lines without polarity concerns. Its hard-glass construction and Category 1 metallurgical bonds ensure stable performance under thermal cycling and radiation exposure per MicroNote 050.
The JANTX1N6164AUS/TR delivers 1500 W peak pulse power at 10/1000 µs waveform while maintaining ≤5 µA standby current at 62.2 V, with a temperature coefficient of breakdown voltage (αVBR) of 0.100 %/°C - critical for precision hold-off stability over wide operating temperatures.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 62.2 V - maximum continuous reverse/forward voltage before conduction begins; defines safe operating margin below clamping threshold |
| VC @ IPP | 112.8 V at 13.3 A - clamped voltage during 10/1000 µs surge; limits downstream component stress |
| PPP | 1500 W - peak transient energy absorption capability; supports MIL-STD-461 CS115/116-level surges |
| IPP | 13.3 A - maximum non-repetitive surge current the device can safely divert without degradation |
| TJ/TSTG | –55 °C to +175 °C - extended junction/storage range enables operation in engine bay or space-grade environments |
| RθJEC | 5.0 °C/W - low thermal resistance from junction to end cap enables high-power dissipation with minimal temperature rise |
| αVBR | 0.100 %/°C - predictable VBR drift over temperature; supports accurate system-level voltage margining |
Pinout & Package
Package: SQ-MELF "C" - hermetically sealed voidless hard-glass body with tungsten slugs and tin/lead-plated copper terminals; square-end-cap geometry enables precise automated placement and reliable solder joint formation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (bidirectional) | Reversible conduction path | No polarity marking required; symmetric clamping allows installation without orientation check |
| End Cap (both ends) | Thermal and electrical interface | Primary heat path to PCB; requires full-surface solder contact for rated RθJEC = 5.0 °C/W |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection on AC lines or floating DC rails without external diode pairing |
| Voidless hermetic seal | Eliminates internal moisture ingress and intermetallic degradation - essential for >20-year field life in sealed enclosures |
| Category 1 metallurgical bonds | Guarantees bond integrity under mechanical shock (MIL-STD-883 Method 2002) and thermal cycling (–55 °C/+175 °C, 1000 cycles) |
| MIL-PRF-19500/516 JANTX qualification | Validated screening includes lot acceptance tests for parametric stability, burn-in, and hermeticity - required for DoD procurement |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N6164US | Commercial-grade version; no MIL-PRF-19500/516 qualification; same VWM, VC, PPP | Lacks JANTX screening; unsuitable for DoD or space programs requiring traceable reliability data | Select only for cost-sensitive industrial prototypes where long-term reliability testing is performed internally |
| JANTXV1N6164AUS | Higher reliability screening (JANTXV level); tighter parametric limits; enhanced burn-in and hermeticity testing | Required for flight-critical subsystems; adds ~15% cost premium for extended lifetime validation | Choose when system-level FMEA mandates zero-failure probability over 15+ years in orbit or combat deployment |
Compared with JANTX1N6164AUS/TR, the commercial 1N6164US offers identical electrical specs but no military screening, while JANTXV1N6164AUS adds stricter process controls and test coverage - making the JANTX variant the optimal balance of certified reliability and program affordability for Tier-1 defense contractors.

FAQ
What is the clamping voltage of JANTX1N6164AUS/TR at its rated peak pulse current?
The JANTX1N6164AUS/TR has a maximum clamping voltage (VC) of 112.8 V when subjected to its rated 13.3 A peak pulse current (IPP) under the standard 10/1000 µs waveform. This value is guaranteed per MIL-PRF-19500/516 test conditions and reflects worst-case device behavior after JANTX-level screening. The JANTX1N6164AUS/TR maintains this clamping performance across its full operating temperature range.
Is JANTX1N6164AUS/TR compatible with lead-free reflow processes?
JANTX1N6164AUS/TR uses tin/lead-plated terminals and is rated for solder temperature up to 260 °C for 10 seconds, making it compatible with standard SnPb reflow profiles. While RoHS-compliant matte-tin versions exist for commercial-grade parts, the JANTX1N6164AUS/TR itself is not RoHS-compliant and must be processed in dedicated SnPb lines to avoid intermetallic contamination and ensure hermetic seal integrity.
Does JANTX1N6164AUS/TR require polarity-aware PCB layout?
No - the JANTX1N6164AUS/TR is a bidirectional TVS with symmetrical breakdown characteristics, and its SQ-MELF "C" package has no polarity marking. PCB layout may orient either end toward the protected node without affecting clamping performance. This simplifies assembly and eliminates risk of reverse installation in high-density layouts common in avionics modules.
What is the thermal resistance specification for JANTX1N6164AUS/TR, and how does it impact PCB design?
JANTX1N6164AUS/TR specifies a junction-to-end-cap thermal resistance (RθJEC) of 5.0 °C/W. To achieve this rating, both end caps must be fully soldered to adequately sized copper pads with direct thermal vias to inner ground planes. Inadequate pad area or missing thermal vias will increase effective RθJA, risking thermal runaway during repetitive surge events. The JANTX1N6164AUS/TR datasheet provides exact pad layout dimensions on page 7.
How does the JANTX qualification level differ from JANTXV for JANTX1N6164AUS/TR?
JANTX qualification for JANTX1N6164AUS/TR includes full MIL-PRF-19500/516 screening: lot acceptance tests, burn-in, and hermeticity verification. JANTXV adds tighter parametric limits, extended burn-in duration, and additional mechanical shock/vibration testing. Both meet the same baseline electrical specs, but JANTXV is mandated for flight hardware where zero latent defects are required - whereas JANTX suffices for ground-support equipment using JANTX1N6164AUS/TR.
