Overview
The STTH3002CT is a high-efficiency ultrafast diode produced by STMicroelectronics. This dual center tab rectifier is specifically designed for use in switch mode power supplies (SMPS) and high-frequency DC to DC converters. The device is packaged in the TO-220AB format, making it suitable for applications requiring low voltage and high frequency operation.
The STTH3002CT is characterized by its low forward and reverse recovery times, high surge current capability, and high junction temperature tolerance. These features make it an ideal choice for low voltage, high frequency inverters, free-wheeling diodes, and polarity protection circuits.
