CMMSH1-40L www.centralsemi.com SURFACE MOUNT LOW V F SILICON SCHOTTKY RECTIFIER DESCRIPTION: 1 AMP, 40 VOLTS The CENTRAL SEMICONDUCTOR CMMSH1-40L is a 1.0A, Low V , Silicon Schottky Rectifier. This high F efficiency, Low V Schottky features high current F 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.
