Q8004D4TP

Triacs Overview

The Littelfuse Q8004D4TP is a bidirectional triac designed for AC power control applications. It features an RMS on-state current of 4 A and a rated repetitive peak off-state voltage (VDRM) of 800 V. The device operates within a junction temperature range of -40°C to +125°C and utilizes a TO-252-3 surface-mount package. Key electrical parameters include a maximum holding current of 30 mA, a gate trigger voltage of 2.5 V, and a gate trigger current ranging from 25 mA to 50 mA. Non-repetitive peak on-state currents are specified at 46 A and 55 A under different pulse conditions.

Triacs Feature Summary

• Bidirectional switching capability for alternating current circuits
• Surface-mount construction in a compact TO-252-3 package
• High thermal stability with operation up to 125°C

Triacs Applications

• AC motor speed control systems
• Solid-state relay designs
