SDT4U40EP3 Image

The SDT4U40EP3 from Diodes Incorporated is a Trench Schottky Barrier Diode that is optimized for low forward voltage drop and low leakage current. It has a forward current of 4 A and a forward voltage of 0.55 V. This power diode has a repetitive peak reverse voltage of up to 40 V and a reverse current of up to 150 µA. It has a low forward voltage that minimizes conduction losses and improves efficiency. This AEC-Q100/101/200 qualified power diode has low heat resistance, which enables design challenges with increasing efficiency while reducing board space. It is available as a chip that measures 1.28 x 1.28 mm and is ideal for portable applications such as blocking diode, boost diode, switching diode and reverse protection diode.
