QJ6025RH5TP

Triacs Overview

The Littelfuse QJ6025RH5TP is a high-temperature bidirectional triac designed for robust power switching applications. It features an RMS on-state current (It RMS) of 25 A and a rated repetitive off-state voltage (VDRM) of 600 V. The device exhibits a maximum holding current (Ih) of 50 mA, with gate trigger voltage (Vgt) and current (Igt) specified at 1.3 V and 50 mA respectively. On-state voltage is rated at 1.8 V, while leakage current remains at 10 uA under VDRM conditions. Operating temperatures range from -40 C to +150 C. The component utilizes a TO-220AB non-isolated package for through-hole mounting.

Triacs Feature Summary

• High-temperature capability supporting operation up to +150 C
• Sensitive gate design enabling direct interfacing with control logic
• Non-isolated construction within a standard TO-220AB housing

Triacs Applications

• Industrial motor speed control systems
• Solid-state relay implementations
• High-temperature lighting dimmer circuits

Triacs Procurement Notes

Verify the specific suffix RH5TP against official Littelfuse documentation to confirm pinout configuration and thermal characteristics. Ensure the procurement channel provides valid RoHS compliance certificates. Cross-reference the manufacturer part number with authorized distributor databases to validate authenticity and traceability before finalizing orders.

Triacs Selection Notes

Select this component when a 25 A RMS current rating and 600 V blocking voltage are required in a non-isolated form factor. The TO-220AB package facilitates heatsinking for thermal management. Verify that the 50 mA gate trigger current aligns with the driving circuit's output capabilities. Confirm that the operating environment stays within the specified -40 C to +150 C temperature range.

Triacs Part Context

This triac belongs to the QJxx25xHx series, which focuses on high-temperature performance and ruggedness. The 'QJ' prefix typically denotes specific Littelfuse thyristor families optimized for industrial durability. The 25A rating places it in the medium-power switching category, suitable for applications requiring reliable commutation under varying load conditions.

Triacs Replacement Considerations

The Q6025R5 is a related 25 A, 600 V triac but operates at a lower maximum temperature of 125 C and uses a different gate trigger profile. Substitution requires verifying thermal derating curves and ensuring the replacement package matches the PCB footprint constraints.
