CMMR1U-02 TR PBFREE

Single Diodes Overview

The CMMR1U-02 TR PBFREE is a surface mount ultra fast recovery silicon rectifier from Central Semiconductor Corp. It features a 1.0 A average forward current and a 200 V peak repetitive reverse voltage. The device utilizes an SOD-123F case, which reduces board space by 58% compared to the SMA package. Key electrical parameters include a maximum reverse leakage current of 1.0 µA at rated voltage, a typical forward voltage of 1.0 V at 1.0 A, and a junction capacitance of 9.0 pF. The reverse recovery time is typically 50 ns.

Single Diodes Feature Summary

• Flat lead design and clip assembly facilitate larger die size and improved thermal efficiency
• SOD-123F case provides a 67% lower profile and occupies significantly less board space than standard SMA packages
• Ultra fast recovery characteristics suitable for high-speed switching applications

Single Diodes Applications

• Commercial equipment power supplies
• Industrial control systems
• Automotive electronics
• Computer power units

Single Diodes Procurement Notes

Verify that the ordering suffix matches the required plating specification. The PBFREE designation indicates lead-free plating compliance. Confirm the reel packaging type aligns with automated assembly requirements. Ensure the specific part number corresponds to the 200V rating variant within the CMMR1U series. Cross-reference manufacturer documentation for any recent environmental or compliance updates.

Single Diodes Selection Notes

Select this component when a low-profile surface mount rectifier is required for 200V circuits. The SOD-123F package offers space savings over traditional SMA footprints. Consider the 50 ns reverse recovery time for high-frequency applications. Evaluate thermal resistance values based on the available copper pad area on the PCB layout to ensure adequate heat dissipation under load conditions.

Single Diodes Part Context

This device belongs to the CMMR1U Series, which covers voltage ratings from 200V to 800V in a single 1.0 Amp surface mount form factor. The series is designed for general-purpose rectification in commercial, industrial, and automotive environments. The CMMR1U-02 specifically denotes the 200V variant within this lineup, sharing identical physical dimensions and thermal characteristics with higher voltage versions.

Single Diodes Replacement Considerations

Direct substitutes within the same series include CMMR1U-04 (400V), CMMR1U-06 (600V), and CMMR1U-08 (800V) if voltage headroom permits. Other manufacturers offering SOD-123F ultra-fast rectifiers with similar 1A/200V specifications may be considered, provided pinout compatibility and reverse recovery times are verified against the original datasheet.
