STTH3R06

STTH3R06 is a silicon ultrafast recovery rectifier diode from STMicroelectronics. It is designed for high‑frequency rectification in switch‑mode power supplies and DC‑DC converters. Key specs (typical): VRRM around 600 V and IF(AV) about 3 A, with a fast reverse‑recovery time (t rr in the tens of nanoseconds) and a modest forward voltage drop. The device can handle repetitive peak reverse voltages up to 600 V while conducting a few amps of average forward current, making it suitable for high‑frequency rectification, freewheeling, and secondary/auxiliary rectification in SMPS topologies. STTH3R06 is offered in surface‑mount and other standard packages, enabling compact, low‑loss designs in power electronics.
