STMicroelectronics BTA40-800B is an 800V, 40A standard TRIAC suitable for high-power AC switching applications. This device features a robust RD91 insulated package designed for chassis mounting, ensuring efficient thermal management. The BTA40-800B offers a maximum on-state current of 40A (RMS) and a non-repetitive surge current rating of up to 420A for 50Hz operation. It requires a gate trigger current (Igt) of 50mA maximum and a gate trigger voltage (Vgt) of 1.3V maximum. The holding current (Ih) is a maximum of 80mA. Operating across a temperature range of -40°C to 125°C (TJ), this TRIAC is commonly employed in industrial motor control, lighting control, and power supply systems.
