STTH302

STTH302 Description

The STTH302 from STMicroelectronics is a general-purpose fast recovery diode designed for high-efficiency rectification in power electronics. With a 200V reverse voltage (Vr) and 3A average forward current (Io), it delivers robust performance in demanding circuits. Its ultra-fast recovery time (35ns trr) minimizes switching losses, making it ideal for high-frequency applications. The diode features a low forward voltage drop (950mV @ 3A), enhancing energy efficiency, and operates reliably up to 175°C junction temperature. Packaged in DO-201AD (Through Hole), it is RoHS3 compliant and REACH unaffected, ensuring environmental and regulatory compliance.
