Quality Control: Learn More
The STMicroelectronics STTH312B-TR is a high-voltage, fast-recovery rectifier diode. This component is rated for a maximum repetitive peak reverse voltage (Vr) of 1200 V and an average forward rectified current (Io) of 3 A. It features a low forward voltage (Vf) of 2 V at 3 A and a reverse leakage current of 10 µA at 1200 V. The reverse recovery time (trr) is specified at 115 ns, classifying it as a fast-recovery diode. Designed for surface mounting, it is housed in a TO-252-3, DPAK (2 Leads + Tab), SC-63 package, supplied on tape and reel. Key applications include power factor correction, high-frequency inverters, and switch-mode power supplies across industrial, automotive, and consumer electronics sectors. The operating junction temperature range extends up to 175°C (Max).
