Overview
The CMSSH-3SE TR PBFREE is a dual Schottky diode array in series configuration, manufactured by Central Semiconductor Corp. It utilizes an SOT-323 surface mount package and features enhanced specifications compared to the standard CMSSH-3 series. Key electrical parameters include a peak repetitive reverse voltage of 40 V and a continuous forward current rating of 200 mA per diode. The device exhibits a maximum forward voltage of 0.8 V at 100 mA and a typical reverse leakage current of 500 nA at 25°C. Operating junction temperature ranges from -65°C to +150°C.
Feature Summary
- Dual diodes configured in series within a compact SOT-323 surface mount package
- Enhanced specification offering increased continuous forward current capacity
- Low forward voltage drop characteristics for improved efficiency
- High thermal stability with extended operating junction temperature range
Applications
- DC-DC converter circuits requiring series diode configurations
- Power supply rectification stages
- General-purpose switching applications in portable electronics
Procurement Notes
Verify the specific ordering suffix against manufacturer documentation to confirm plating options and packaging format. Ensure the requested variant matches the required electrical enhancements and pinout configuration for the series arrangement. Confirm availability through authorized distributors as lead times may vary based on production schedules.
Selection Notes
Select this component when a series-connected dual Schottky configuration is required in a small footprint. The enhanced specifications provide higher current handling and lower forward voltage compared to standard versions. Verify that the 40 V reverse voltage rating meets the circuit requirements and that the SOT-323 package dimensions fit the design constraints.
Part Context
This part belongs to the CMSSH-3E series of enhanced specification silicon Schottky diodes. The series includes single, common anode, common cathode, and series variants. The CMSSH-3SE specifically denotes the dual in-series marking code '3SE'. These devices are designed for surface mount assembly and offer improved performance metrics over previous generations.
Replacement Considerations
Standard CMSSH-3SE parts may be replaced by CMSSH-3SE TR PBFREE if enhanced specifications are acceptable. Verify pin compatibility and electrical ratings before substitution. Other series variants like CMSSH-3AE or CMSSH-3CE have different internal configurations and are not direct replacements.
