CMSSH-3A TR PBFREE

Diode Arrays Overview

The CMSSH-3A TR PBFREE is a surface mount silicon Schottky diode from the Central Semiconductor CMSSH-3 series, housed in an SOT-323 package. It features a dual common anode configuration with a peak repetitive reverse voltage of 30 V and a continuous forward current rating of 100 mA per diode. The device exhibits a low forward voltage drop, typically ranging from 0.29 V to 1.00 V depending on current levels, and supports a peak forward surge current of 750 mA. Designed for fast switching applications, it operates within a junction temperature range of -65°C to +150°C.

Diode Arrays Feature Summary

• Dual common anode configuration integrating two Schottky diodes in a single compact SOT-323 package
• Low forward voltage drop characteristics optimized for efficient power conversion and signal rectification
• Fast switching performance with minimal reverse recovery time suitable for high-frequency circuits

Diode Arrays Applications

• Fast switching rectification in low-power electronic circuits
• Power management systems requiring low voltage drop components

Diode Arrays Procurement Notes

Verify that the ordering suffix PBFREE confirms lead-free plating compliance as specified by the manufacturer. Ensure the reel packaging quantity matches production requirements. Confirm the specific marking code B1D corresponds to the dual common anode variant during incoming inspection to prevent assembly errors.

Diode Arrays Selection Notes

Select this component when a dual common anode topology is required in a minimal footprint. The SOT-323 package offers space efficiency compared to larger through-hole alternatives. Consider the 30 V reverse voltage limit and 100 mA continuous current rating to ensure adequate headroom for the target application's electrical stress conditions.

Diode Arrays Part Context

This part belongs to the CMSSH-3 series of surface mount silicon Schottky diodes manufactured by Central Semiconductor Corp. The series includes variants with different internal configurations, such as single, common cathode, and in-series arrangements, all sharing similar electrical performance profiles and thermal characteristics within the same SOT-323 form factor.

Diode Arrays Replacement Considerations

Direct substitutes include other SOT-323 dual common anode Schottky diodes with matching 30 V and 100 mA ratings. Verify pinout compatibility and forward voltage specifications before substitution to maintain circuit performance integrity.
