QJ6030LH4TP

Triacs Overview

The Littelfuse QJ6030LH4TP is a bidirectional triac designed for phase control applications, housed in an SMTO-218 (TO-220) through-hole package. It features a rated repetitive off-state voltage of 600 V and an RMS on-state current capability of 30 A. The device supports a non-repetitive peak on-state current of 350 A with a maximum on-state voltage of 1.5 V. Gate triggering requirements include a maximum gate trigger voltage of 1 V and a maximum gate trigger current of 35 mA. The component operates within a temperature range of -40°C to +150°C and exhibits a maximum holding current of 60 mA.

Triacs Feature Summary

• Bidirectional thyristor structure enabling full-wave AC power control
• High thermal stability supporting operation up to 150°C junction temperature
• Robust surge handling capability with 350 A non-repetitive peak current rating

Triacs Applications

• AC motor speed control circuits

Triacs Procurement Notes

Verify the specific suffix LH4TP against the manufacturer's latest datasheet to confirm pinout orientation and insulation class. Ensure the ordering quantity aligns with the factory packaging configuration of 1000 units per tube. Confirm RoHS compliance status directly from the official documentation before finalizing procurement specifications.

Triacs Selection Notes

Select this component when a 600 V blocking voltage and 30 A continuous current are required in a TO-220 form factor. Evaluate the gate trigger current of 35 mA to ensure compatibility with the driving logic circuit. Consider the thermal resistance of the SMTO-218 package and the necessity of a heatsink for sustained high-current operation above ambient limits.
