QJ8025LH4TP

Triacs Overview

The Littelfuse QJ8025LH4TP is a high-temperature TRIAC from the QJxx25xHx series, rated for 800 V repetitive off-state voltage and 25 A RMS on-state current. It features a non-latching gate trigger with a maximum gate trigger current of 35 mA and a maximum gate trigger voltage of 1.3 V. The device operates within a junction temperature range of -40°C to +150°C and utilizes a TO-220AB package with an isolated tab for through-hole mounting.

Triacs Feature Summary

• High-temperature operation capability up to 150°C junction temperature
• Sensitive gate design allowing direct interfacing with microprocessors
• Isolated tab construction in TO-220AB package for efficient heat dissipation

Triacs Applications

• Industrial motor control systems
• Solid-state relays
• High-temperature power switching circuits

Triacs Procurement Notes

Verify the specific suffix LH4TP against official Littelfuse documentation to confirm pinout configuration and isolation characteristics. Ensure the procurement channel provides valid RoHS compliance certificates matching the manufacturer's current declarations. Cross-reference the datasheet revision date to ensure compatibility with latest thermal derating curves.

Triacs Selection Notes

Select this component when applications require robust performance at elevated temperatures exceeding standard 125°C limits. The 25 A rating suits moderate power loads where sensitive gate drive currents are preferred. Verify that the TO-220AB footprint fits the target PCB layout and that the isolated tab meets insulation requirements for the specific enclosure design.

Triacs Part Context

This part belongs to the QJxx25xHx series of high-temperature TRIACs manufactured by Littelfuse. The series is designed for demanding environments requiring reliable switching at junction temperatures up to 150°C. It shares common electrical characteristics with other members of the family but differs in specific packaging and thermal resistance parameters defined by the manufacturer.

Triacs Replacement Considerations

Direct substitutes include QJ8025RH4TP, which shares identical electrical ratings but may differ in thermal resistance or manufacturing lot specifications. Verify pin compatibility and thermal management requirements before substitution.
