BTA04-700SRG

Triacs Overview

The BTA04-700SRG is a standard gate Triac manufactured by STMicroelectronics, designed for general-purpose AC switching applications. It features an RMS on-state current rating of 4 A and a repetitive peak off-state voltage of 700 V. The device operates within a junction temperature range of -40°C to +125°C and utilizes a surface-mount TO-263 (D2PAK) package. Key electrical parameters include a maximum non-repetitive surge current of 42 A, a typical on-state voltage of 1.65 V, and a maximum holding current of 15 mA. Gate triggering requirements specify a maximum voltage of 1.5 V and a maximum current of 5 mA.
