MBR120ESFT1G

Single Diodes Overview

The MBR120ESFT1G is a surface mount Schottky power rectifier manufactured by onsemi, utilizing the Schottky Barrier principle with a large area metal-to-silicon diode. It is housed in a plastic SOD-123FL package (CASE 498) designed for automated board assembly. The device features a peak repetitive reverse voltage of 20 V and an average rectified forward current of 1.0 A at a lead temperature of 140°C. Key electrical parameters include a maximum instantaneous forward voltage of 595 mV at 1.0 A and 100°C junction temperature, and a maximum reverse current of 10 µA at 25°C. It supports a non-repetitive peak surge current of 40 A and operates within a junction temperature range of -65°C to +150°C.
