Overview
The FERD20H100STS is a 100 V, 20 A field-effect rectifier diode produced by STMicroelectronics. This device is based on ST's advanced rectifier process, which achieves the best in class VF/IR trade-off for a given silicon surface. It is optimized for use in confined casing applications where both efficiency and thermal performance are critical. The FERD20H100STS features a low forward voltage drop, reduced leakage current, and stable leakage current over reverse voltage, making it an excellent replacement for 100 V Schottky diodes.
