Overview
The STPS20L15D is a low drop OR-ing power Schottky diode produced by STMicroelectronics. This device is specifically designed for use in fault-tolerant power supply equipment, particularly in OR-ing applications. It is available in two package types: TO-220AC and D²PAK. The STPS20L15D is known for its very low forward voltage drop, which reduces power dissipation and the need for large heatsinks. It also features avalanche capability and is ECOPACK®2 compliant, making it an environmentally friendly option.
