Product details
Overview
JANTXV1N6143US/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), 8.4 V working standoff voltage (VWM), and 15.6 V clamping voltage (VC) at 96.2 A peak pulse current. It operates across –55 °C to +175 °C and is used in avionics power bus protection against lightning-induced surges.
For engineers reviewing the JANTXV1N6143US/TR datasheet, JANTXV1N6143US/TR pinout, JANTXV1N6143US/TR application, or JANTXV1N6143US/TR equivalent, key selection criteria include MIL-PRF-19500/516 JANTXV qualification level, bidirectional clamping behavior, thermal resistance of 5.0 °C/W (junction-to-end cap), and IEC 61000-4-5 secondary lightning protection capability.
Technical Context
This TVS diode employs hard-glass construction with internal Category 1 metallurgical bonds for high-reliability operation under extreme thermal and surge stress. Its bidirectional architecture provides symmetrical clamping without polarity marking, enabling placement flexibility in DC or AC-coupled signal/power lines.
It delivers 1500 W peak pulse power per 10/1000 µs waveform while maintaining a low 5.0 °C/W junction-to-end-cap thermal resistance. Standby current is limited to 20 µA at 8.4 V VWM, and temperature coefficient of breakdown voltage is +0.07 %/°C - critical for stable clamping across wide operating temperatures.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 8.4 V - maximum continuous reverse/forward voltage before conduction begins; defines circuit operating margin before clamping. |
| VC @ IPP | 15.6 V at 96.2 A - clamped voltage during 10/1000 µs surge; determines protected circuit's maximum transient overvoltage exposure. |
| PPP | 1500 W - peak impulse power handling capacity; enables robust protection against high-energy transients like lightning-induced surges. |
| RθJEC | 5.0 °C/W - thermal resistance from junction to end cap; supports reliable power dissipation in high-temperature environments up to +175 °C. |
| TJ/TSTG | –55 °C to +175 °C - qualified operating and storage temperature range; meets extended military environmental requirements. |
| ID @ VWM | 20 µA - leakage current at rated standoff voltage; ensures minimal standby power loss and no false triggering in low-power systems. |
| αV(BR) | +0.07 %/°C - temperature coefficient of breakdown voltage; guarantees predictable VBR shift across temperature, aiding system-level margin analysis. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N6143US/TR | Commercial-grade version; same VWM, VC, and PPP, but not MIL-PRF-19500/516 qualified; RoHS-compliant matte-tin plating available. | Lacks JANTXV screening; unsuitable for flight-critical or space-qualified designs requiring radiation hardness and extended temperature validation. | Select when cost-sensitive industrial or ground-based systems require identical electrical specs without military screening. |
| JANTXV1N6142US/TR | Lower VWM (7.6 V), lower VC (14.5 V), higher IPP (103.4 A); otherwise identical package, qualification, and thermal specs. | Better suited for 24 V nominal systems with tighter clamping margin; trades off higher surge current handling for reduced clamping voltage. | Choose when protecting lower-voltage rails where sub-15 V clamping is mandatory and 103.4 A surge capability is sufficient. |
Compared with 1N6143US/TR and JANTXV1N6142US/TR, JANTXV1N6143US/TR uniquely balances 8.4 V standoff with 15.6 V clamping in a JANTXV-qualified SQ-MELF package - making it optimal for 28 V aerospace buses requiring both MIL-spec reliability and precise voltage margin control.

FAQ
What is the clamping voltage of JANTXV1N6143US/TR at its rated peak pulse current?
The JANTXV1N6143US/TR has a maximum clamping voltage (VC) of 15.6 V at 96.2 A peak pulse current (IPP) for a 10/1000 µs waveform. This value is guaranteed under standard test conditions per MIL-PRF-19500/516 and defines the upper voltage limit imposed on protected circuits during surge events. The JANTXV1N6143US/TR maintains this clamping performance across its full operating temperature range.
Is JANTXV1N6143US/TR suitable for bidirectional signal line protection?
Yes, JANTXV1N6143US/TR is a bidirectional TVS diode with symmetrical clamping characteristics - meaning it conducts equally in both polarities. This makes it ideal for protecting AC-coupled data lines, differential buses like CAN or RS-485, and floating sensor inputs without requiring polarity-aware layout. Its lack of polarity marking simplifies automated placement in JANTXV1N6143US/TR-based designs.
What does the "JANTXV" prefix indicate for JANTXV1N6143US/TR?
The "JANTXV" prefix on JANTXV1N6143US/TR denotes compliance with the highest screening level under MIL-PRF-19500/516, including extended temperature testing (–55 °C to +175 °C), burn-in, and life testing. JANTXV qualification exceeds JANTX and JAN levels, confirming suitability for flight hardware, satellite subsystems, and other applications where zero-failure tolerance is mandated.
How does JANTXV1N6143US/TR handle thermal dissipation during repeated surges?
JANTXV1N6143US/TR features a junction-to-end-cap thermal resistance (RθJEC) of 5.0 °C/W, enabling efficient heat transfer to the PCB pads. For repetitive surges, derating follows MIL-PRF-19500/516 guidelines: linear derating from full 1500 W at TEC = 150 °C to zero at TEC = 175 °C. Sustained operation requires controlled end-cap temperature via adequate copper area and solder coverage.
Can JANTXV1N6143US/TR replace JANTXV1N6142US/TR in an existing design?
JANTXV1N6143US/TR is not a direct replacement for JANTXV1N6142US/TR due to differing electrical parameters: JANTXV1N6143US/TR has a higher VWM (8.4 V vs. 7.6 V) and VC (15.6 V vs. 14.5 V), and lower IPP (96.2 A vs. 103.4 A). Substitution requires revalidation of clamping margin and surge current headroom in the target circuit. The JANTXV1N6143US/TR should only be used where its specific 8.4 V standoff is required.
