how to check smd bridge rectifier diode MB10S
BRIDGE RECT 1P 1KV 500MA 4SOIC
The MB10S from ON Semiconductor is an integrated full-bridge rectifier in a small SOIC-4 package. This article is going to explain features, specs, applications, circuits, and other details about the MB10S bridge rectifier for your reference.
The MB10S is a 0.5 A rectifier that achieves strong surge current absorption while having a small footprint.
The MB10S impresses in its surge capability despite its compact 35 mm2 form factor. The design supports a 35 A IFSM rating and a 5.0 A2Sec I2T rating to sustain strong surge currents. Breakdown voltages of up to 1000 V are also rated for devices in the family. The MB10S qualities make it excellent for small power supplies that require a bit of extra surge protection.

The MB10S is an integrated full-bridge rectifier. It is made up of four diodes that are connected in a bridge configuration in one package. Normally, four individual diodes on a PCB are used to do this, but using an integrated solution like the MB10S saves space and evenly distributes power dissipation, whereas any of the four discrete diodes could fail. The internal circuit diagram of the MB10S is shown in the picture below.
MB10S Application Circuit
When dealing with switching supplies that demand a big decoupling capacitor after the rectifier, the 35A peak current rating comes in handy. This capacitor charges just at the positive and negative peaks of the input sine wave, putting a significant peak load on the rectifier (as illustrated in the diagram below) that the MB10S can handle.
