MUR340S V7G

Single Diodes Overview

The MUR340S V7G is a 3A, 400V ultrafast surface mount rectifier from the MUR3xS series by Taiwan Semiconductor. It utilizes glass passivated chip junctions and operates within a -55°C to +175°C junction temperature range. Key electrical parameters include a repetitive peak reverse voltage of 400V, an average forward current of 3A, and a peak forward surge current of 75A. The device features a typical reverse recovery time of 50ns at IF=0.5A and IR=1.0A, with a maximum forward voltage of 1.25V at 3A. It is housed in a DO-214AB (SMC) package.

Single Diodes Procurement Notes

Verify that the ordering code matches the specific voltage rating required for the application. Confirm the suffix indicates the correct tape and reel packing quantity of 3,000 units per reel. Ensure compliance with RoHS standards and halogen-free requirements as specified in the datasheet documentation.

Single Diodes Selection Notes

Select this component when a 400V reverse voltage rating and 3A continuous forward current are necessary. The DO-214AB package is appropriate for surface mount designs requiring compact footprints. Consider the 50ns reverse recovery time for high-frequency switching operations where fast response is critical.

Single Diodes Part Context

This part belongs to the MUR305S through MUR360S series, which covers voltage ratings from 50V to 600V. All members share identical mechanical dimensions and thermal characteristics but differ in their repetitive peak reverse voltage specifications. The series is designed for general purpose ultrafast rectification tasks.

Single Diodes Replacement Considerations

Other parts within the MUR3xS series may be substituted if the voltage rating meets or exceeds the circuit requirements. Verify that any replacement maintains the same DO-214AB package and similar electrical parameters such as forward current and recovery time.
