Overview
The FERD20H100SB-TR, produced by STMicroelectronics, is a 100 V, 20 A field-effect rectifier diode. This device is based on a proprietary technology that 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 diode features a lower dependency of leakage current (IR) and forward voltage (VF) on temperature, reducing the risk of thermal runaway and making it a suitable replacement for 100 V Schottky diodes.
