QJ4006DH2RP

Triacs Overview

The Littelfuse QJ4006DH2RP is a bidirectional triac from the QJxx06xH series, designed for AC switching and phase control. It features a 6 A RMS on-state current (It RMS) and a rated repetitive off-state voltage (VDRM) of 400 V. The device operates within a temperature range of -40°C to +150°C and utilizes a TO-252-3 surface-mount package. Key electrical parameters include an on-state voltage of 1.4 V, a gate trigger voltage (Vgt) of 1.3 V, and a gate trigger current (Igt) of 35 mA. The off-state leakage current is specified at 10 uA under VDRM conditions.
