Overview
The CDBMT240L-G is a low-profile Schottky barrier rectifier from Comchip Technology, housed in an SOD-123H package. It features a maximum average forward current of 2A and a repetitive peak reverse voltage of 40V. The device exhibits a maximum forward voltage drop of 400mV at 2A and a maximum reverse leakage current of 1mA. It supports a forward surge current of 50A and operates within a junction temperature range of -55°C to +150°C.
Feature Summary
- Low profile package design that is significantly thinner than standard SOD-123 components
- Ultra-high-speed switching capability for efficient power conversion
- Excellent thermal resistance and power dissipation characteristics
- Guarding functionality against overvoltage conditions
Applications
- High-reliability power switching circuits
- DC-DC converter input or output rectification
- Free-wheeling diode applications in inductive loads
- Polarity protection in electronic systems
Procurement Notes
Verify the specific suffix 'L' indicates the low-profile SOD-123H variant rather than standard SOD-123. Confirm RoHS compliance status through official manufacturer documentation. Ensure the ordering part number matches the exact electrical ratings required for the target application circuit design.
Selection Notes
Select this component when space constraints require a thinner footprint compared to standard SOD-123 packages. Choose based on the 2A current rating and 40V voltage breakdown requirements. Consider the low forward voltage drop for improved efficiency in low-voltage power supply designs.
Part Context
This device belongs to the CDBMT series of low-profile Schottky barrier rectifiers. The series emphasizes reduced physical dimensions while maintaining high current capabilities. It utilizes silicon epitaxial planar chip technology with metal-silicon junctions for reliable performance in surface-mount applications.
Replacement Considerations
Direct substitutes include other 40V 2A Schottky diodes in SOD-123H packages such as the CDBA240LL-G. Verify pinout compatibility and thermal characteristics before substitution. Ensure replacement parts meet the same reverse leakage and forward voltage specifications.
