Product details
Overview
JANTXV1N6161AUS/TR from Microsemi is a voidless hermetically sealed surface-mount bidirectional Transient Voltage Suppressor (TVS) qualified to MIL-PRF-19500/516 at JANTXV reliability level. It provides 47.1 V working standoff voltage (VWM), 58.9 V minimum breakdown voltage (V(BR)) at 20 mA, and clamps transients to 85.3 V at 17.6 A peak pulse current (IPP) for 10/1000 µs waveform - deployed in military avionics power rail protection.
For engineers reviewing the JANTXV1N6161AUS/TR datasheet, JANTXV1N6161AUS/TR pinout, JANTXV1N6161AUS/TR application, or JANTXV1N6161AUS/TR equivalent, key selection criteria include its 1500 W peak pulse power rating, -55°C to +175°C operating junction temperature range, Category 1 metallurgical bonds, RoHS-compliant tin/lead termination option, and SQ-MELF "C" package compatibility with automated SMT placement.
Technical Context
This TVS operates bidirectionally with no polarity marking and uses hard-glass construction with tungsten slugs for thermal robustness. Its clamping behavior is defined by a 10/1000 µs double-exponential surge waveform, and it maintains stable V(BR) with a temperature coefficient of 0.100 %/°C.
The device achieves 1500 W peak pulse power (PPP) at 25°C and derates linearly above 150°C case temperature to zero at 175°C. Thermal resistance from junction to end cap (RθJEC) is 5.0 °C/W, enabling high-energy transient absorption without thermal runaway in constrained aerospace PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 47.1 V - maximum continuous reverse/forward voltage before conduction begins; sets safe operating margin below system rail voltage. |
| V(BR) min | 58.9 V @ 20 mA - guaranteed breakdown onset threshold; ensures predictable turn-on during overvoltage events. |
| VC @ IPP | 85.3 V @ 17.6 A - clamped voltage during 10/1000 µs surge; defines worst-case stress on downstream ICs. |
| PPP | 1500 W - peak impulse power handling capability; supports lightning-induced surge immunity per IEC61000-4-5 Level 3. |
| TJ Range | -55°C to +175°C - full military temperature operation; validated for engine bay and space-grade thermal cycling. |
| RθJEC | 5.0 °C/W - low thermal resistance to end cap; enables direct heat sinking to copper pour or chassis for sustained pulse duty. |
Pinout & Package
Package: SQ-MELF "C" (hermetically sealed voidless hard glass with tungsten slugs); dimensions: BD = 0.183–0.202 in (4.65–5.13 mm), BL = 0.205–0.245 in (5.21–6.22 mm); weight ≈ 1100 mg; terminals are tin/lead plated copper (RoHS matte-tin available for commercial grade only).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode | Bidirectional terminal pair | No polarity marking - symmetric conduction in both directions; connects across protected line-to-line or line-to-ground. |
| End Cap | Thermal interface | Primary heat path to PCB copper or heatsink; requires soldered contact to thermal pad for RθJEC spec compliance. |
Key Features
| Feature | Design Value |
|---|---|
| Voidless hermetic seal | Eliminates internal moisture ingress and bond degradation over 20+ year field life in humid or vacuum environments. |
| Category 1 metallurgical bonds | Ensures mechanical integrity under shock/vibration up to 100 g; required for MIL-PRF-19500/516 JANTXV qualification. |
| Triple-layer passivation | Prevents surface leakage and corrosion on glass body; maintains ID ≤ 5 µA at VWM across extended temperature and humidity stress. |
| SQ-MELF geometry | Enables precise pick-and-place alignment and consistent solder joint formation in high-reliability automated assembly lines. |
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 |
|---|---|---|---|
| 1N6161US | Commercial-grade version; same electrical specs but not MIL-PRF-19500/516 qualified; no JANTXV reliability screening. | Lacks radiation hardness, thermal cycling validation, and long-term parametric stability data required for flight hardware. | Select only for non-mission-critical ground test equipment where cost outweighs lifetime reliability. |
| JANTXV1N6162AUS/TR | Higher VWM (51.7 V) and V(BR) (64.6 V); clamps at 97.1 V @ 15.4 A; identical package and qualification level. | Better suited for 36 V nominal systems; trades lower clamping headroom for higher standoff margin against normal-mode ripple. | Choose when protecting 36 V avionics buses where 47.1 V VWM risks false triggering during startup overshoot. |
Compared with JANTXV1N6161AUS/TR, the 1N6161US sacrifices military qualification for cost reduction, while JANTXV1N6162AUS/TR offers higher standoff for 36 V systems at the expense of 7% higher clamping voltage - requiring revalidation of downstream IC voltage margins.

FAQ
What is the maximum clamping voltage of JANTXV1N6161AUS/TR under a 10/1000 µs surge?
The JANTXV1N6161AUS/TR clamps to a maximum of 85.3 V when subjected to a 10/1000 µs surge waveform at its rated peak pulse current of 17.6 A. This value is measured per MIL-STD-750 Method 3019 and is guaranteed across the full -55°C to +175°C junction temperature range. The clamping voltage directly determines the peak stress imposed on protected circuitry, making it a critical parameter for downstream IC voltage rating validation.
Is JANTXV1N6161AUS/TR compatible with lead-free reflow processes?
JANTXV1N6161AUS/TR uses standard tin/lead termination and is rated for solder temperature up to 260°C for 10 seconds, matching SnPb reflow profiles. While RoHS-compliant matte-tin versions exist for commercial-grade parts (e.g., 1N6161AUS), the JANTXV1N6161AUS/TR variant is not qualified for lead-free reflow due to its MIL-PRF-19500/516 JANTXV screening requirements and legacy termination specification.
How does the temperature coefficient affect JANTXV1N6161AUS/TR's breakdown voltage in extreme environments?
JANTXV1N6161AUS/TR has a V(BR) temperature coefficient of +0.100 %/°C, meaning its breakdown voltage increases by approximately 0.059 V per °C rise above 25°C. At +125°C junction temperature, V(BR) rises to ~64.8 V - ensuring reliable turn-on margin above system rail voltage even in engine bay or avionics bay thermal extremes.
Can JANTXV1N6161AUS/TR be used in line-to-line configuration?
Yes, JANTXV1N6161AUS/TR is explicitly designed for bidirectional operation and is routinely applied line-to-line in MIL-STD-1275E and DO-160G compliant systems. Its symmetric IV curve and absence of polarity marking allow direct placement between any two conductors requiring transient isolation - including differential data lines, dual-rail supplies, and ungrounded AC inputs.
What is the steady-state power dissipation limit for JANTXV1N6161AUS/TR at 25°C ambient?
At TA = 25°C, JANTXV1N6161AUS/TR has a steady-state power dissipation limit of 3.0 W, as specified in the Maximum Ratings table. This rating assumes adequate PCB copper area for thermal conduction; derating follows the curve in Figure 4, dropping to zero at 150°C case temperature. For continuous operation, designers must ensure junction temperature stays ≤175°C using RθJEC = 5.0 °C/W and thermal interface design.
