MRS30M

Bridge Rectifier Overview

The MRS30M is a surface-mount fast recovery bridge rectifier manufactured by Diodes Incorporated. It features a glass passivated die construction and operates with a peak repetitive reverse voltage of 1000 V and an average rectified output current of 3.0 A at a case temperature of +130°C. The device exhibits a maximum forward voltage of 1.3 V at 3 A and a leakage current of 5 μA at 1,000 V under standard conditions. Its total capacitance is 45 pF, and the reverse-recovery time is limited to 250 ns. The component is housed in an MSBL package and supports operating temperatures from -55°C to +150°C.

Bridge Rectifier Procurement Notes

Verify that the specific orderable part number matches the required packaging configuration. The standard MRS30M variant is supplied in tape and reel carriers with a quantity of 2500 units per carrier. Confirm compliance with RoHS directives and halogen-free requirements if environmental specifications are mandatory for the intended deployment.

Bridge Rectifier Selection Notes

Select this component when high-voltage isolation up to 1000 V is required alongside a 3.0 A continuous current rating. Ensure the application environment accommodates the specified thermal resistance values and junction-to-ambient parameters. Verify that the 250 ns reverse-recovery time aligns with the switching frequency requirements of the target circuit design.
