How To Use MB10S Bridge Rectifier

The MB10S is an integrated full-bridge rectifier. It contains four diodes in the same package connected together in a bridge configuration. This is usually done using four diodes on a PCB, but using an integrated solution like MB10S saves space and evens out power dissipation, whereas any of the four discrete diodes usually used might fail. The internal circuit diagram of the MB10S is shown in the figure below.

MB10S Internal Circuit

The 35A peak current rating is particularly helpful when dealing with switching supplies, that require a large decoupling capacitor after the rectifier. This capacitor only charges at the positive and negative peaks of the input sine wave, and this places a large peak load on the rectifier as shown in the figure below, which the MB10S is capable of handling.
