CMSSH-3CE TR PBFREE

Diode Arrays Overview

The CMSSH-3CE TR PBFREE is a dual Schottky diode array manufactured by Central Semiconductor Corp, housed in an SOT-323 (SC-70) surface-mount package. It features a common cathode configuration with a maximum repetitive reverse voltage of 40 V and an average forward current rating of 200 mA. The device exhibits a low forward voltage drop of 650 mV at rated current and supports a peak forward surge current of 750 mA. Operating temperatures range from -65°C to +150°C junction temperature, with a maximum reverse leakage current of 100 µA.

Diode Arrays Feature Summary

• Logic level clamping applications

Diode Arrays Procurement Notes

Verify the specific ordering suffix 'TR PBFREE' against the manufacturer's latest documentation to ensure correct tape-and-reel packaging and lead-free compliance status. Confirm that the SOT-323 package dimensions match the target PCB footprint requirements prior to finalizing procurement orders. Cross-reference the datasheet revision date to ensure all electrical parameters align with current production standards.

Diode Arrays Selection Notes

Select this component when a dual Schottky rectifier with common cathode topology is required in space-constrained designs. The 40 V rating suits low-voltage DC bus applications, while the 200 mA current capacity supports moderate load switching. Consider the SOT-323 package size relative to available board real estate and verify thermal management needs given the small form factor and 250 mW power dissipation capability.

Diode Arrays Part Context

This part belongs to Central Semiconductor's enhanced specification Schottky diode family, designed for high-efficiency rectification in portable and industrial electronics. The CMSSH series utilizes silicon carbide Schottky technology to achieve superior switching performance compared to standard PN junction diodes. It complements other variants in the lineup such as the CMPSH-3AE, offering different internal configurations for diverse circuit topologies.

Diode Arrays Replacement Considerations

Direct substitutes include the CMPSH-3AE TR PBFREE, which shares similar electrical characteristics but utilizes a common anode configuration rather than common cathode. Designers must verify pinout compatibility when swapping between these variants to prevent circuit malfunction due to incorrect polarity connection.
