The MUH1PD-M3/89A with Rectifiers 1.0 Amp 200 Volt 10 Amp IFSM is an electronic part manufactured by Vishay, which is a series of power diodes (or rectifiers) that are designed to quickly and efficiently allow current to pass in only one direction. These components are generally used to convert alternating current (AC) into direct current (DC) and are typically found in a broad range of power supplies, motor controls, power inverters, switching power supplies, and motor control circuits. They feature a maximum forward voltage drop of 1.0 V and a maximum IFSM of 200 V 10 A.
