Q8025LH5

Triacs Overview

The Littelfuse Q8025LH5 is a bidirectional triac designed for high-temperature and high dv/dt applications. It features an RMS on-state current of 25 A and a non-repetitive peak on-state current of 250 A. The device supports a rated repetitive off-state voltage (VDRM) of 800 V with an on-state voltage of 1.5 V. Gate triggering parameters include a maximum holding current of 75 mA, a gate trigger voltage of 1.3 V, and a gate trigger current of 50 mA. It operates within a temperature range of -40°C to +150°C and utilizes a TO-220-3 insulated package for through-hole mounting.

Triacs Feature Summary
