CMFSH-3I BK TIN/LEAD

Diode Arrays Overview

The CMFSH-3I BK TIN/LEAD is a Schottky diode array manufactured by Central Semiconductor Corp. It features two independent diodes in a TO-253-4 package. The device supports a maximum DC reverse voltage of 30 V and an average rectified current of 100 mA. Key electrical parameters include a forward voltage of 1 V at 100 mA, a reverse leakage current of 500 nA at 25 V, and a reverse recovery time of 5 ns. Operating junction temperature ranges from -65°C to 150°C.

Diode Arrays Feature Summary

• Dual independent Schottky diode configuration for compact circuit design
• Low forward voltage drop of 1 V at rated current
• Fast reverse recovery time of 5 ns for high-speed switching applications

Diode Arrays Applications

• High-frequency rectification circuits
• Power supply input protection
• Free-wheeling diode applications in inductive loads

Diode Arrays Procurement Notes

Verify the specific suffix 'BK TIN/LEAD' against the manufacturer's official documentation to confirm lead composition and packaging format. Ensure the procurement channel provides valid RoHS exemption certificates if required, as this variant contains lead. Cross-reference the part number with the distributor's inventory status to confirm availability and authenticity before ordering.

Diode Arrays Selection Notes

Select this component when a dual-diode solution is required in a surface-mount package with fast switching characteristics. The 30 V reverse voltage rating suits low-voltage applications. Consider the TO-253-4 footprint constraints and thermal management requirements for the 100 mA current rating. Verify compatibility with existing PCB silkscreen and assembly processes.

Diode Arrays Part Context

This part belongs to the CMFSH series of Schottky diode arrays from Central Semiconductor Corp. It offers a dual-diode alternative to single diodes, saving board space. The tin/lead finish distinguishes it from lead-free variants, catering to specific manufacturing or legacy system requirements where leaded components are specified.

Diode Arrays Replacement Considerations

Potential substitutes include other dual Schottky arrays in TO-253-4 packages with similar 30 V and 100 mA ratings. Verify pinout compatibility and thermal resistance values. Check if lead-free alternatives meet regulatory requirements for the target application.
