CDBMT230L-HF

Overview

The CDBMT230L-HF is a surface-mount Schottky barrier rectifier from Comchip Technology, housed in an SOD-123H package. It features a 30V repetitive peak reverse voltage and a 2A average forward current capability. The device utilizes silicon epitaxial planar chip technology with a metal-silicon junction for ultra-high-speed switching. Key electrical parameters include a low forward voltage drop of 0.5V at rated current and a maximum surge forward current of 50A. It operates within a junction temperature range of -55°C to +150°C, offering excellent power dissipation and thermal resistance suitable for compact designs.

Feature Summary

• Ultra-high-speed switching with soft recovery characteristics
• Low profile package design significantly thinner than standard SOD-123
• High efficiency due to low forward voltage drop
• Guarding against overvoltage conditions

Applications

• DC-DC converters
• Power supply rectification
• Free-wheeling diodes in inductive circuits
• Overvoltage protection circuits

Procurement Notes

Verify the specific suffix 'HF' confirms halogen-free compliance as per manufacturer documentation. Confirm the SOD-123H package dimensions match your PCB footprint requirements. Ensure the operating temperature range meets your system's thermal constraints. Cross-reference the datasheet revision date to ensure parameter accuracy. Validate RoHS status through official component declarations.

Selection Notes

Select this component when space constraints require a low-profile Schottky rectifier with moderate current handling. The 30V rating suits low-voltage DC bus applications. Consider the 2A continuous current limit for load requirements. The high surge capability supports transient loads. Compare thermal resistance values against alternative packages for heat dissipation needs.

Part Context

This part belongs to the CDBMT Series Low Profile Schottky Barrier Rectifiers. The series emphasizes reduced physical size while maintaining robust electrical performance. It targets modern electronics requiring miniaturization without sacrificing switching speed or thermal management capabilities.

Replacement Considerations

Check for direct pin-compatible alternatives within the same series, such as CDBMT240-HF for higher voltage ratings. Verify equivalent forward voltage and reverse leakage specifications before substitution. Ensure the replacement maintains the SOD-123H package form factor.
