STMicroelectronics BTA40 BTA41 BTB41 TRIACs Datasheet
This datasheet details the electrical and thermal characteristics of STMicroelectronics' BTA40, BTA41, and BTB41 TRIACs. These devices are designed for general-purpose AC switching applications, including static relays, heating regulation, and phase control. The BTA series features an insulated tab rated at 2500 V rms. Key specifications include on-state RMS current up to 40 A, repetitive peak off-state voltage of 600–800 V, and low thermal resistance. The datasheet also covers absolute maximum ratings, static characteristics, thermal resistance, and package information for RD91 and TOP3 insulated packages.
