Microchip Technology JANTXV1N6141AUS/TR

Overview

JANTXV1N6141AUS from Microsemi is a military-qualified, voidless hermetically sealed surface-mount bidirectional Transient Voltage Suppressor (TVS) with 6.9 V working standoff voltage (VWM), 8.65 V minimum breakdown voltage (V(BR)), and 13.4 V clamping voltage (VC) at 111.9 A peak pulse current (IPP); designed for lightning surge and ESD protection in high-reliability aerospace and defense power rail interfaces.

For engineers reviewing the JANTXV1N6141AUS datasheet, JANTXV1N6141AUS pinout, JANTXV1N6141AUS application, or JANTXV1N6141AUS equivalent, key selection criteria include its MIL-PRF-19500/516 JANTXV qualification, 1500 W 10/1000 µs peak pulse power rating, -55°C to +175°C operating junction temperature range, and SQ-MELF "C" package compatibility with automated SMT placement.

Technical Context

This TVS operates bidirectionally without polarity marking and uses hard-glass construction with internal Category 1 metallurgical bonds to ensure radiation hardness and long-term reliability under thermal cycling and mechanical shock. Its clamping behavior is defined by a 13.4 V VC at 111.9 A IPP under standardized 10/1000 µs waveform conditions.

The device exhibits a low 0.06 %/°C temperature coefficient of breakdown voltage (αV(BR)) and maintains 100 µA maximum standby current (ID) at rated 6.9 V standoff, enabling stable overvoltage protection across extended temperature ranges without false triggering in low-power monitoring circuits.

FAQ

What is the clamping voltage of JANTXV1N6141AUS and under what test condition is it specified?

JANTXV1N6141AUS has a maximum clamping voltage (VC) of 13.4 V, measured at 111.9 A peak pulse current (IPP) using the standard 10/1000 µs double-exponential surge waveform. This value defines the upper voltage limit imposed on protected circuitry during transient events and is validated per MIL-PRF-19500/516 test requirements.

Is JANTXV1N6141AUS suitable for bidirectional signal line protection?

Yes, JANTXV1N6141AUS is inherently bidirectional with no polarity marking and symmetric clamping characteristics. It protects AC-coupled, differential, or floating signal paths-such as MIL-STD-1553B or RS-422 lines-by conducting equally for positive and negative transients, making JANTXV1N6141AUS ideal for balanced interface protection without orientation concerns.

What does the "JANTXV" prefix indicate for JANTXV1N6141AUS?

The "JANTXV" prefix certifies that JANTXV1N6141AUS meets Level V screening per MIL-PRF-19500/516, including extended burn-in, temperature cycling, and lot acceptance testing. This qualification ensures suitability for high-reliability applications where failure modes must be eliminated, distinguishing JANTXV1N6141AUS from commercial or lower-tier JAN/JANTX variants.

Does JANTXV1N6141AUS comply with IEC61000-4-2 and IEC61000-4-4 standards?

JANTXV1N6141AUS provides ESD protection per IEC61000-4-2 and EFT protection per IEC61000-4-4 as stated in its official Microsemi documentation. Its 1500 W peak pulse power rating and low clamping voltage enable compliance in system-level testing when integrated with appropriate layout practices and upstream filtering, confirming JANTXV1N6141AUS as a validated solution for these immunity standards.

What is the thermal resistance and maximum steady-state power rating of JANTXV1N6141AUS?

JANTXV1N6141AUS has a thermal resistance junction-to-end cap (R_θJEC) of 5.0 °C/W and a maximum off-state power rating of 5.0 W up to 150 °C end-cap temperature (derating linearly to zero at 175 °C). At 25 °C ambient, its steady-state power dissipation is limited to 3.0 W, defining safe continuous operation limits for bias network design and thermal management planning around JANTXV1N6141AUS.
