This datasheet provides detailed information on the BTA201 series B, E and ER triacs, including product description, features, applications, and quick reference data.
The BTA201 series includes B, E and ER logic‑level triacs offered in a plastic TO‑92 package. The B series is designed for full RMS current commutation, while the E and ER series are optimized for low‑power driver interfacing, such as microcontrollers. Typical applications are motor control and solenoid drivers.
Key specifications include a peak off‑state voltage of up to 800 V, RMS on‑state currents of 12.5 A (600 V version) to 13.7 A (800 V version), a maximum junction temperature of 125 °C, and a storage temperature rating of +150 °C. Detailed pinning, ordering information, thermal resistance, and dynamic characteristics are provided in the sheet.
