These characteristics make it ideal for heavy duty applications that demand long term reliability. STTH812G STTH812G STTH812G-TR STTH812G STTH812FP STTH812FP STTH812DI STTH812DI Such demanding applications include industrial power supplies, motor control, and similar mission-critical systems that require rectification and freewheeling. These diodes also fit into auxiliary functions such as snubber, bootstrap, and demagnetization applications. The improved performance in low leakage current, and therefore thermal runaway guard band, is an immediate competitive advantage for this device.
