CMR3U-04M TR13 PBFREE

Single Diodes Overview

The CMR3U-04M TR13 PBFREE is a surface mount silicon ultra fast recovery rectifier manufactured by Central Semiconductor Corp. It features an average forward current of 3.0 A and a peak repetitive reverse voltage of 400 V. The device utilizes glass passivated chip technology with C bend construction for strain relief. Electrical characteristics include a maximum forward voltage of 1.25 V at 3.0 A and a typical reverse recovery time of 50 ns. Operating junction temperature ranges from -65 to +175 °C, housed in an SMB package.

Single Diodes Feature Summary

• Glass passivated chip design ensures high reliability
• Ultra fast recovery characteristics suitable for high-speed switching
• C bend lead construction provides mechanical strain relief on the PC board

Single Diodes Applications

• Commercial electronic equipment power supplies
• Industrial control systems
• Automotive electronics applications

Single Diodes Procurement Notes

Verify the specific ordering suffix matches the required plating configuration. Confirm that the TR13 designation aligns with the intended reel packaging quantity requirements. Ensure the PBFREE marking corresponds to the environmental compliance standards mandated by the target application regulations before finalizing procurement orders.

Single Diodes Selection Notes

Select this component when a 400 V rating is required alongside a 3.0 A continuous current capacity. The 50 ns reverse recovery time makes it appropriate for circuits demanding faster switching speeds than standard rectifiers. Consider the SMB package dimensions for available PCB real estate constraints during the layout phase.

Single Diodes Part Context

This part belongs to the CMR3U series of surface mount ultra fast recovery rectifiers. The series spans voltage ratings from 100 V to 1000 V while maintaining a consistent 3.0 A current handling capability across all variants. The CMR3U-04M specifically addresses the 400 V segment of this product line.

Single Diodes Replacement Considerations

Direct substitutes within the same manufacturer family include the CMR3U-01M, CMR3U-02M, CMR3U-06M, and CMR3U-10M. These alternatives share identical physical dimensions and thermal characteristics but differ in their maximum reverse voltage ratings.
