STPS640CBY-TR ST Arrays

The STPS640CBY-TR is a 40V/6A dual common-cathode Schottky rectifier in a DPAK package, AEC-Q101 qualified for automotive and high-reliability applications. Select this diode when your design demands high efficiency—its 630mV forward voltage per diode at 3A and 100µA leakage minimize losses in high-frequency switching. The common-cathode configuration suits synchronous rectification and OR-ing. Key applications include automotive DC-DC converter output rectification, freewheeling diodes in motor drives, solar inverter bypass circuits, and reverse polarity protection. It also excels in industrial power supplies, battery chargers, and telecom rectifiers, with a -40°C to +150°C junction range ensuring reliable performance in harsh environments.
