QJ4025RH5TP

Triacs Overview

The Littelfuse QJ4025RH5TP is a bidirectional triac designed for high-temperature AC switching applications. It features a rated repetitive off-state voltage (VDRM) of 400 V and an on-state RMS current (It RMS) of 25 A. The device operates within a temperature range of -40°C to +150°C, utilizing a TO-220AB non-isolated package with through-hole mounting. Key electrical parameters include a maximum holding current of 50 mA, a gate trigger current of 50 mA, and an on-state voltage of 1.8 V. The component exhibits a low leakage current of 10 uA at VDRM.

Triacs Feature Summary

• High-temperature capability up to 150°C for demanding environments
• Integrated gate trigger functionality for phase control
• Robust 25 A RMS current handling in standard industrial packages

Triacs Applications

• Industrial motor speed controls
• Temperature modulation systems
• AC power switching circuits

Triacs Procurement Notes

Verify the specific suffix 'H5TP' against the manufacturer's latest datasheet to confirm pinout orientation and thermal characteristics. Ensure the procurement channel provides original Littelfuse documentation to validate RoHS compliance and manufacturing origin. Cross-reference the part number with authorized distributors to avoid counterfeit components.

Triacs Selection Notes

Select this component when a 400 V rating and 25 A continuous current are required alongside extended thermal operation up to 150°C. The TO-220AB non-isolated package necessitates careful thermal management and insulation planning if mounted to a heatsink. Compare gate sensitivity requirements against the 50 mA trigger specification to ensure compatible drive circuitry.

Triacs Part Context

This part belongs to the Littelfuse QJxx25xHx series of high-temperature triacs. It shares the 25 A current capacity and 400 V voltage rating with other members of the family but distinguishes itself through its specific thermal grade and packaging configuration. The series is engineered for reliable performance in harsh industrial conditions.

Triacs Replacement Considerations

The Q4025R5 is a related variant within the same manufacturer's portfolio. Note that the Q4025R5 typically has a lower maximum operating temperature of 125°C compared to the 150°C rating of the QJ4025RH5TP. Verify thermal requirements before substitution.
