Overview
The STPS6045CW is a dual center tap Schottky rectifier produced by STMicroelectronics. This device is specifically designed for use in switch-mode power supplies and high-frequency DC to DC converters. It is packaged in the TO-247 format, which is suitable for applications requiring low voltage and high frequency operations. The STPS6045CW is ideal for use in low voltage, high frequency inverters, free wheeling, and polarity protection applications due to its very small conduction losses, negligible switching losses, and extreme fast switching capabilities.
