STTH8S12D

STTH8S12D Description

The STTH8S12D from STMicroelectronics is a high-performance general-purpose diode designed for demanding power electronics applications. With a 1200V reverse voltage (Vr) and 8A average rectified current (Io), it offers robust performance in high-voltage circuits. The diode features a fast recovery time of 45ns, making it suitable for high-frequency switching applications. Its low forward voltage drop (2.7V @ 8A) ensures efficient power handling, while the reverse leakage current of just 5µA @ 1200V minimizes energy losses. Packaged in a TO-220AC through-hole mount, it provides excellent thermal management, supporting operation up to 175°C junction temperature. Compliant with ROHS3 and REACH standards, it is ideal for environmentally conscious designs.
