MB2S45

Bridge Rectifier Overview

The MB2S45 is a single-phase bridge rectifier manufactured by Vishay General Semiconductor - Diodes Division. It features a peak reverse voltage of 200 V and an average rectified forward current of 500 mA. The device utilizes standard silicon technology and operates within a junction temperature range of -55°C to 150°C. It is housed in a TO-269AA (MBS) surface mount package, also known as 4-BESOP. The component exhibits a maximum forward voltage of 1 V at 400 mA and a reverse leakage current of 5 µA at 200 V.

Bridge Rectifier Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct packaging and compliance status. Confirm that the requested variant matches the required thermal and electrical specifications for the target application environment. Cross-reference the part number with the latest datasheet to validate availability and manufacturing status before finalizing procurement orders.

Bridge Rectifier Selection Notes

Select this component when a surface mount single-phase bridge rectifier with 200 V blocking voltage and 500 mA current capacity is required. Ensure the PCB footprint supports the TO-269AA package dimensions. Consider the thermal management requirements for the specified operating temperature range during circuit design.

Bridge Rectifier Part Context

This component belongs to the MB2 series of bridge rectifiers from Vishay. It provides a surface mount alternative to through-hole variants like the MB2M. The MB2S45 designation indicates the specific package and rating configuration within the broader product family designed for low-power rectification tasks.

Bridge Rectifier Replacement Considerations

The MB2S-E3/45 and MB2S-E3/80 are documented parameter-equivalent alternatives from the same manufacturer. Verify pinout compatibility and thermal characteristics when substituting these parts.
