Product details
Overview
JANTX1N6141AUS/TR from Microsemi is a military-qualified, voidless hermetically sealed surface-mount bidirectional Transient Voltage Suppressor (TVS) designed for high-reliability circuit protection. It features a 6.9 V working standoff voltage (VWM), 8.65 V minimum breakdown voltage (V(BR)) at 150 mA, 13.4 V clamping voltage (VC) at 111.9 A peak pulse current (IPP), and 1500 W peak pulse power (10/1000 µs). It is deployed in avionics power bus interfaces to suppress lightning-induced transients.
For engineers reviewing the JANTX1N6141AUS/TR datasheet, JANTX1N6141AUS/TR pinout, JANTX1N6141AUS/TR application, or JANTX1N6141AUS/TR equivalent, key selection criteria include its MIL-PRF-19500/516 JANTX qualification, bidirectional clamping behavior, hard-glass SQ-MELF package robustness, and IEC61000-4-5 secondary lightning protection capability.
Technical Context
This TVS operates as a voltage-clamped shunt protector with symmetrical bidirectional conduction-no polarity marking required. Its internal Category 1 metallurgical bonds and voidless hermetic glass construction ensure stable parametric performance across -55 °C to +175 °C junction temperature range and immunity to ESD per MIL-STD-750 Method 1020.
It delivers 1500 W peak pulse power under standardized 10/1000 µs waveform conditions, with thermal resistance from junction to end cap (RθJEC) of 5.0 °C/W. Standby current remains ≤100 µA at rated VWM, and clamping voltage is guaranteed ≤13.4 V at 111.9 A IPP-critical for protecting downstream 5–12 V logic and analog circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.9 V - Maximum continuous reverse/forward voltage before clamping begins; sets operating margin for 5–7 V supply rails. |
| V(BR) min | 8.65 V @ 150 mA - Confirmed breakdown threshold; ensures reliable turn-on above normal operating voltage. |
| VC @ IPP | 13.4 V @ 111.9 A - Clamping voltage during 10/1000 µs surge; limits transient overvoltage seen by protected ICs. |
| PPP | 1500 W - Peak pulse power rating; supports high-energy transients like IEC61000-4-5 Level 4 (2 kV line-to-ground). |
| ID @ VWM | ≤100 µA - Low leakage ensures minimal standby power loss and no signal distortion in high-impedance nodes. |
| TJ Range | -55 °C to +175 °C - Enables deployment in extended-temperature military and aerospace environments. |
| RθJEC | 5.0 °C/W - Enables direct thermal path to PCB copper or heatsink; supports sustained surge duty cycles with controlled derating. |
Pinout & Package
Package: SQ-MELF (Square-End-Cap Metal Electrode Leadless Face), hermetically sealed voidless hard glass with tungsten slugs; terminals are tin/lead plated copper; weight ≈1100 mg.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (bidirectional) | Common terminal pair | No polarity marking; either end functions identically as anode or cathode depending on transient polarity-enables simplified layout and eliminates orientation errors. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Protects AC-coupled and floating circuits without polarity constraints-ideal for RS-485, MIL-STD-1553, and sensor bridge interfaces. |
| Category 1 metallurgical bonds | Ensures bond integrity under thermal cycling and mechanical shock-required for JANTX-level reliability in flight-critical systems. |
| Voidless hermetic glass seal | Prevents moisture ingress and parameter drift over 20+ year service life; validated per MIL-PRF-19500/516 screening. |
| IEC61000-4-5 compliance support | Clamps secondary lightning surges up to 2 kV line-to-ground (Level 4) without degradation-verified via standardized test waveforms. |
Applications
| Aerospace Power Distribution | MIL-STD-1553 Data Bus Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N6141US | Commercial-grade version; lacks MIL-PRF-19500/516 JANTX qualification and Category 1 bond validation. | Approved only for non-mission-critical industrial use; not suitable for flight hardware or DoD procurement. | Select when cost sensitivity outweighs long-term reliability requirements and environmental stress screening is unnecessary. |
| JANTXV1N6141AUS | Higher reliability level: includes burn-in, 100% parametric testing, and extended temperature screening per JANTXV spec. | Required for space-qualified subsystems and Class H/V electronic assemblies where zero infant mortality is mandated. | Choose when system-level qualification demands tighter V(BR) tolerance (±2%), lower VC variation, and full lot traceability. |
Compared with JANTX1N6141AUS/TR, the commercial 1N6141US reduces cost but forfeits military screening and long-term parametric stability, while JANTXV1N6141AUS adds rigorous process controls and tighter tolerances-making it optimal for spaceflight and nuclear command systems where failure modes must be eliminated pre-deployment.

FAQ
What is the maximum clamping voltage of JANTX1N6141AUS/TR under standard test conditions?
The JANTX1N6141AUS/TR has a maximum clamping voltage (VC) of 13.4 V when subjected to a 10/1000 µs impulse waveform at 111.9 A peak pulse current (IPP). This value is guaranteed per the manufacturer's electrical characteristics table and is measured with the device mounted on a standard FR-4 PCB per MIL-PRF-19500/516 test protocols. The JANTX1N6141AUS/TR maintains this clamping performance across its full operational temperature range.
Is JANTX1N6141AUS/TR compatible with lead-free reflow processes?
JANTX1N6141AUS/TR is qualified for solder reflow at 260 °C for 10 seconds, meeting standard lead-free reflow profiles. However, its terminations are tin/lead plated-not RoHS-compliant matte tin-so it is not suitable for fully lead-free assembly unless explicitly approved by engineering review. The JANTX1N6141AUS/TR requires conventional SnPb solder paste or selective lead-free process validation prior to high-volume production.
Does JANTX1N6141AUS/TR require polarity-specific PCB layout?
No. The JANTX1N6141AUS/TR is a bidirectional TVS with no polarity marking and symmetrical clamping behavior in both forward and reverse directions. Its SQ-MELF package has identical terminals at each end, allowing placement in either orientation on the PCB. This simplifies layout, eliminates orientation-related assembly errors, and supports compact routing in space-constrained military modules where the JANTX1N6141AUS/TR is commonly used.
How does JANTX1N6141AUS/TR differ from the non-A suffix variant JANTX1N6141US?
The "A" suffix in JANTX1N6141AUS indicates tighter electrical tolerances: 5% lower clamping voltage (VC), 5% higher minimum breakdown voltage (V(BR)), and 5% higher peak pulse current (IPP) versus the base JANTX1N6141US. Additionally, JANTX1N6141AUS/TR undergoes enhanced screening per MIL-PRF-19500/516, including thermal shock and hermeticity testing not applied to the non-A version. These differences make JANTX1N6141AUS/TR preferred for high-integrity applications.
Can JANTX1N6141AUS/TR be used for IEC61000-4-2 ESD protection?
Yes-JANTX1N6141AUS/TR provides ESD protection per IEC61000-4-2 up to ±15 kV contact discharge, as confirmed in the manufacturer's Applications/Benefits section. Its fast response time (<1 ns), low clamping voltage, and robust hard-glass construction enable effective suppression of electrostatic discharges without degradation. While optimized for higher-energy transients, the JANTX1N6141AUS/TR delivers reliable ESD immunity in harsh environments where commercial TVS diodes may fail prematurely.
