Overview
The CDBMT120-HF is a low profile surface mount Schottky barrier rectifier manufactured by Comchip Technology. It features a SOD-123H package and utilizes a silicon epitaxial planar chip with a metal-silicon junction. The device supports a repetitive peak reverse voltage of 20 V, a continuous forward current of 1.0 A, and a maximum forward surge current of 25 A. Electrical characteristics include a typical forward voltage of 0.70 V at 1.0 A, a maximum reverse current of 0.5 mA at 25°C, and a typical thermal resistance of 98 °C/W. Operating temperatures range from -55°C to +125°C.
Feature Summary
- Low profile package design that is 40% thinner than standard SOD-123 packages.
- Ultra high-speed switching capability for efficient power conversion.
- Guarding functionality designed for overvoltage protection applications.
- Lead-free construction compliant with MIL-STD-19500/228 environmental standards.
Applications
- High frequency rectification in DC-DC converters
- Power supply input rectification stages
- Free-wheeling diodes in inductive load circuits
Procurement Notes
Verify the specific part number against official manufacturer documentation to confirm electrical ratings and package dimensions. Ensure compliance with required operating temperature ranges and mounting specifications before integration into final designs.
Selection Notes
Select this component for applications requiring low forward voltage drop and high efficiency in compact form factors. Consider the 20 V reverse voltage rating and 1.0 A current capacity when designing circuits with corresponding voltage and current loads.
Part Context
This component belongs to the CDBMT series of low profile Schottky barrier rectifiers. The series offers various voltage ratings from 20 V to 150 V within the same SOD-123H package footprint, allowing for standardized board layouts across different voltage requirements.
Replacement Considerations
Cross-reference with other SOD-123H Schottky rectifiers offering 20 V reverse voltage and 1.0 A forward current. Verify pinout compatibility and thermal resistance values to ensure equivalent performance in existing designs.
