QJ6008RH4TP

Triacs Overview

The Littelfuse QJ6008RH4TP is a bidirectional triac in the Qxx06xH series, housed in a TO-220AB-3 through-hole package. It supports an RMS on-state current of 8 A and a rated repetitive off-state voltage (VDRM) of 600 V. The device features a maximum on-state voltage of 1.5 V and a gate trigger voltage (Vgt) of 1.3 V with a gate trigger current (Igt) of 35 mA. Non-repetitive on-state currents are rated at 83 A and 100 A. Leakage current is limited to 10 uA at VDRM, with a maximum holding current of 35 mA. Operating temperatures range from -40 C to +150 C.

Triacs Feature Summary

• High temperature capability up to 150 C for robust thermal performance
• Low on-state voltage of 1.5 V for efficient power handling
• Through-hole TO-220AB-3 mounting for secure mechanical installation

Triacs Applications

• Industrial motor control systems
• Solid-state relay circuits
• High-temperature AC power switching applications

Triacs Procurement Notes

Verify the specific Littelfuse datasheet for the QJ6008RH4TP to confirm RoHS compliance details and exact manufacturing lot codes. Ensure the ordering suffix matches the required packaging configuration. Cross-reference the part number against official Littelfuse distribution channels to validate authenticity and avoid counterfeit components during acquisition.

Triacs Selection Notes

Select this component when an 8 A RMS current rating and 600 V blocking voltage are required in a through-hole format. The 150 C maximum operating temperature distinguishes it from standard triacs limited to 125 C. Verify that the 35 mA gate trigger current aligns with the driving circuit capabilities before finalizing the design choice.

Triacs Part Context

This part belongs to the Littelfuse Qxx06xH series of high-temperature Alternistor TRIACs. It shares the 600 V voltage class and 8 A current rating with other members of the family but utilizes the TO-220AB-3 package. This series is designed for applications requiring higher thermal stability than standard thyristors.

Triacs Replacement Considerations

The Q6008DH4TP is a surface-mount alternative in the same voltage and current class but uses a TO-252-3 package and has a lower 125 C temperature rating. Direct pin-to-pin replacement is not possible due to the different mounting styles.
