Introduction

AI Translation

DK5V45R25ST1 is a simple, high-efficiency synchronous rectification IC featuring only two pins — A and K — corresponding to the anode and cathode of a Schottky diode. The IC integrates a 45V power NMOS internally, which significantly reduces diode conduction losses, improves overall system efficiency, and serves as a drop-in replacement for equivalent Schottky rectifier diodes currently on the market. DK5V45R25ST1 is available in a TO-220F package.
