MUR340S M6G

Single Diodes Overview

The MUR340S M6G is a 3A ultra-fast surface mount rectifier diode from the MUR3xS series by Taiwan Semiconductor. It features a glass passivated chip junction and operates within a repetitive peak reverse voltage range of 50V to 600V, with the MUR340S variant rated at 400V VRRM. The device utilizes a DO-214AB (SMC) package and supports a maximum junction temperature of 175°C. Key electrical specifications include a forward current of 3A, a peak forward surge current of 75A, and a typical reverse recovery time of 50ns for this specific voltage rating.

• Freewheeling application
• Switching mode converters in computer systems
• Inverters in telecommunication equipment

Single Diodes Procurement Notes

Verify the component against the official datasheet J2212 revision to confirm the specific 400V rating associated with the MUR340S designation. Ensure the ordering code matches the required packing configuration, as standard availability is listed as 3,000 units per tape and reel. Confirm compliance with RoHS directives and halogen-free status according to IEC 61249-2-21 definitions during sourcing.

Single Diodes Selection Notes

Select this component for designs requiring high-frequency rectification or freewheeling duties where rapid switching speeds are critical. The 400V rating makes it suitable for intermediate voltage levels in power conversion circuits. Consider the thermal resistance of 11 °C/W and the 175°C junction temperature limit when designing heat dissipation strategies for the SMC package.

Single Diodes Part Context

This part belongs to the MUR305S through MUR360S series, which covers a voltage spectrum from 50V to 600V while maintaining a constant 3A current rating. All members of this family share identical mechanical dimensions and packaging standards, differing primarily in their reverse voltage capabilities and corresponding reverse recovery times.

Single Diodes Replacement Considerations

Substitutes must match the 3A current rating, 400V minimum reverse voltage, and DO-214AB (SMC) package. Verify that alternative components offer comparable ultra-fast recovery characteristics and meet the same moisture sensitivity level requirements.
