Diodes Incorporated · Fast switching diode · SOD-123

Surface-mount fast switching diode in a SOD-123 package. Features a low forward voltage of 0.715V max at 1mA, fast reverse recovery time of 4ns max, and low junction capacitance of 2pF max. Rated for 100V reverse voltage and 300mA continuous forward current, suitable for general-purpose switching applications.

Pinout

Pin Name Type Function
1 A passive Anode terminal of the switching diode. Forward current flows from anode to cathode; rated for 300mA continuous forward current (IFM) with a maximum forward voltage of 0.715V at 1mA.
2 K passive Cathode terminal of the switching diode, identified by the cathode band marking on the package top. Rated for 100V peak repetitive reverse voltage (VRRM) with maximum peak reverse current of 1.0µA at VR = 75V.
