CMMSH1-40L SURFACE MOUNT LOW VF SILICON SCHOTTKY RECTIFIER 1 AMP, 40 VOLTS SOD-123F CASE w w w. c e n t r a l s e m i . c o m DESCRIPTION: The CENTRAL SEMICONDUCTOR CMMSH1-40L is a 1.0A, Low VF, Silicon Schottky Rectifier. This high efficiency, Low VF Schottky features high current capacity packaged in a small, thermally efficient, SOD-123F surface mount package. When compared to similar devices in the larger SMA package, this device is 58% smaller, with a 67% lower profile, making it ideally suited for applications where performance and size are critical.
