CMSSH-3S BK PBFREE

Diode Arrays Overview

The CMSSH-3S BK PBFREE is a surface mount silicon Schottky diode from Central Semiconductor, housed in an SOT-323 package. It features a dual-in-series configuration with marking code A5D. Key electrical parameters include a peak repetitive reverse voltage of 30 V and a continuous forward current of 100 mA. The device supports a peak forward surge current of 750 mA and dissipates up to 275 mW. Operating junction temperature ranges from -65°C to +150°C. Typical forward voltage is 0.33 V at 2.0 mA and 1.00 V at 100 mA. Reverse leakage current is typically 500 nA at 25V.

Diode Arrays Procurement Notes

Verify the specific ordering suffix BK against manufacturer documentation to confirm reel packaging or tape-and-reel specifications. Ensure the PBFREE designation aligns with environmental compliance requirements for the target assembly process. Confirm availability through authorized distributors as stock levels fluctuate.

Diode Arrays Selection Notes

Select this component when a dual series Schottky configuration is required within a compact SOT-323 footprint. The 30 V rating suits low-voltage DC applications. Evaluate thermal resistance of 455 °C/W for heat dissipation constraints. Compare forward voltage characteristics against system efficiency targets at expected operating currents.

Diode Arrays Part Context

This part belongs to the Central Semiconductor CMSSH-3 series of surface mount silicon Schottky diodes. The series includes single, common anode, common cathode, and in-series variants. All share the same SOT-323 package and core material properties, differing primarily in internal connection topology and marking codes.

Diode Arrays Replacement Considerations

Direct substitutes must match the SOT-323 package, dual in-series configuration, and 30 V/100 mA ratings. Verify pinout compatibility (Anode D2, Cathode D1, Anode D1/Cathode D2) before substitution.
