These characteristics make it ideal for heavy duty applications that demand long term reliability. Part Number Marking STTH512D STTH512D STTH512B STTH512B STTH512B-TR STTH512B STTH512FP STTH512FP 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.
