QJ6025LH5TP

Triacs Overview

The Littelfuse QJ6025LH5TP is a high-temperature bidirectional triac rated for 600V repetitive peak off-state voltage and 25A RMS on-state current. It operates within a junction temperature range of -40°C to +150°C and features an isolated TO-220AB package. Key electrical parameters include a maximum holding current of 50mA, gate trigger voltage of 1.3V, and gate trigger current of 50mA. The device exhibits a typical on-state voltage of 1.8V and maintains a low off-state leakage current of 10µA at rated voltage.

Triacs Feature Summary

• High thermal stability with a maximum operating junction temperature of +150°C
• Electrically isolated mounting configuration in a TO-220AB package
• Capable of handling high surge currents for robust AC power control

Triacs Applications

• Solid state relays requiring high isolation
• Industrial motor speed control systems
• High-temperature heating element regulation

Triacs Procurement Notes

Verify the specific ordering suffix against official Littelfuse documentation to confirm pinout and isolation specifications. Ensure the procurement channel provides valid manufacturer traceability. Confirm RoHS compliance status through the latest datasheet revision before finalizing supply chain agreements.

Triacs Selection Notes

Select this component when designs demand operation above standard 125°C limits or require galvanic isolation between the heatsink and circuit ground. Compare the 50mA gate trigger requirements against available drive circuitry capabilities. Evaluate thermal management needs based on the 25A RMS rating and package thermal resistance characteristics.

Triacs Part Context

This part belongs to the QJxx25xHx series of high-temperature Alternistors from Littelfuse. These devices are engineered specifically for demanding AC switching applications where reliability under elevated thermal stress is critical. The series offers a balance of high current capacity and extended temperature tolerance compared to standard triacs.

Triacs Replacement Considerations

Direct replacements must match the 600V/25A rating, TO-220AB isolation package, and +150°C temperature capability. Verify equivalent gate sensitivity and holding current specifications to ensure circuit compatibility without redesign.
