Triacs datasheet and documents for QJ4025LH6TP

QJ4025LH6TP

Triacs Overview

The Littelfuse QJ4025LH6TP is a high-temperature isolated triac rated for 400V repetitive off-state voltage and 25A RMS on-state current. It features an 80mA gate trigger current and 1.3V maximum gate trigger voltage, housed in a TO-220AB package with through-hole mounting. The device supports a junction temperature range from -40°C to +150°C, ensuring reliable operation in demanding thermal environments while maintaining low leakage current of 10µA.

Triacs Feature Summary

High-temperature capability up to 150°C junction temperature
Electrically isolated construction for enhanced safety
Low gate trigger current for efficient driver interfacing

Triacs Applications

Industrial motor control systems
High-power AC switching applications
Thermal management critical power electronics

Triacs Procurement Notes

Verify the specific suffix 'L' against official Littelfuse documentation to confirm isolation and high-temperature ratings. Ensure the TO-220AB package matches the target PCB footprint. Cross-reference the 80mA gate trigger specification with circuit requirements. Confirm RoHS compliance status via the manufacturer datasheet before finalizing procurement orders.

Triacs Selection Notes

Select this component when high junction temperature tolerance and electrical isolation are required. The 25A RMS rating suits moderate to high-power AC loads. Verify that the 1.3V gate trigger voltage aligns with available drive signals. Consider the TO-220AB package for adequate heat dissipation without additional active cooling solutions in standard industrial enclosures.

Triacs Part Context

This part belongs to the QJxx25xHx series of isolated triacs designed for robust performance. It complements other Littelfuse thyristors by offering specialized high-temperature operation. The series targets applications requiring reliable switching under extreme thermal stress while maintaining strict isolation standards for user safety and system integrity.
