CMSSH-3 BK PBFREE

Single Diodes Overview

The CMSSH-3 BK PBFREE is a single silicon Schottky diode from Central Semiconductor, housed in an SOT-323 surface mount package. It features a peak repetitive reverse voltage of 30 V and a continuous forward current rating of 100 mA. The device exhibits a low forward voltage drop ranging from 0.29 V to 1.00 V depending on current levels. Electrical characteristics include a maximum reverse leakage current of 500 nA at 25°C and a junction capacitance of 7.0 pF. The component supports an operating temperature range from -65°C to +150°C with a thermal resistance of 455 °C/W.

Single Diodes Procurement Notes

Verify the specific part number against official datasheets to confirm the single diode configuration and SOT-323 packaging. Ensure the 'BK' suffix aligns with manufacturer bulk packaging specifications if required. Confirm RoHS compliance status through the 'PBFREE' designation. Cross-reference electrical limits with application requirements before procurement.

Single Diodes Selection Notes

Select this component for designs requiring compact surface mount solutions with low forward voltage characteristics. The SOT-323 package suits space-constrained layouts. Evaluate the 30 V reverse voltage rating against circuit peaks. Consider the 100 mA continuous current limit for load requirements. Verify thermal management needs given the 455 °C/W thermal resistance.

Single Diodes Part Context

This component belongs to the CMSSH-3 series of surface mount silicon Schottky diodes manufactured by Central Semiconductor Corp. The series includes variants such as CMSSH-3A (dual common anode), CMSSH-3C (dual common cathode), and CMSSH-3S (dual in series). All share similar electrical ratings but differ in internal configuration and marking codes.

Single Diodes Replacement Considerations

Direct substitutes within the same series include CMSSH-3A, CMSSH-3C, and CMSSH-3S, provided the dual configurations meet circuit topology needs. Verify pinout compatibility when replacing with other manufacturers' SOT-323 Schottky diodes.
