Overview
The STTH30R03CG-TR is an ultra-high performance diode from STMicroelectronics, part of the TURBOSWITCH 'R' family. This diode is designed for high-frequency applications and is particularly suited for high-frequency offline SMPS (Switch-Mode Power Supplies) and DC/DC converters. It is known for its hyperfast recovery characteristics, which compete with GaAs devices, and its ability to significantly reduce losses in associated MOSFETs when operating at high dI/dt.
