Q2006R4

Triacs Overview

The Littelfuse Q2006R4 is a bidirectional triac designed for AC switching and phase control applications. It features a rated repetitive off-state voltage of 400 V and an on-state RMS current capacity of 6 A. The device operates within a temperature range of -40°C to +125°C and utilizes an SMTO-263-2 surface-mount package. Key electrical parameters include a maximum holding current of 50 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 65 A and 80 A depending on the specific variant configuration.
