Triacs datasheet and documents for Q4025R5

Q4025R5

Triacs Overview

The Littelfuse Q4025R5 is a bidirectional triac designed for AC power control applications. It features a 400 V rated repetitive off-state voltage (VDRM) and supports an on-state RMS current (It RMS) of 25 A. The device operates within a temperature range of -40 °C to +125 °C and utilizes a TO-220-2 through-hole package. Key electrical parameters include a maximum holding current of 100 mA, a gate trigger voltage of 2.5 V, and a gate trigger current of 50 mA. Non-repetitive peak on-state currents are specified at 167 A and 200 A, with an on-state voltage of 1.8 V and a leakage current of 10 uA.

Triacs Feature Summary
