General Description of MB10F Bridge Rectifier

The MB10F is a bridge rectifier diode in a small surface-mount package and is commonly used for single-phase applications. The maximum input AC voltage of this IC is 700V hence, can be used for a broad range of applications. The maximum DC current that this IC can handle is 800mA. This IC has a reverse breakdown voltage of 1000V and a low forward voltage drop of 1.1V. If you are looking for a compact IC for rectification application this can be a good choice.

 

How to use MB10F Bridge Rectifier

Using the MB-10F is relatively simple. As the name suggests the IC is a full bridge rectifier that is nothing but a construction of four diodes that is shown below.

The simulated circuit below shows how a bridge rectifier behaves when we apply AC voltage to the AC side of the rectifier, and for the DC side, we have put a smoothing capacitor to rectify the pulsed DC to a smoother out DC signal. The output DC voltage of the IC can be calculated using the formula

DC Out = (√2×VRMS) – 1.1  Volts

Where VRMS is the input RMS voltage and -1.1V is for the voltage drop that appears across each diode path during rectification. Though in our simulation we will not get that because in the simulation all devices are ideal devices.
