Q4006RH3

Triacs Overview

The Littelfuse Q4006RH3 is a bidirectional triac designed for AC power control applications. It features a rated repetitive off-state voltage (VDRM) of 400 V and an on-state RMS current (IT(RMS)) of 6 A. The device supports non-repetitive on-state currents of 55 A and 65 A under different pulse conditions. Key electrical parameters include a maximum on-state voltage of 1.6 V, a holding current (IH) maximum of 15 mA, and a gate trigger voltage (VGT) of 1.3 V with a gate trigger current (IGT) of 10 mA. The off-state leakage current at VDRM is specified as 10 uA.

Triacs Feature Summary

• Bidirectional conduction capability for alternating current switching
• Integrated thermal protection mechanisms for enhanced reliability
• High surge current handling capacity for robust operation

Triacs Applications

• AC motor speed control circuits
