Overview
The CDBA240L-HF is a Schottky Barrier Rectifier manufactured by Comchip Technology. It features a single-phase full-wave bridge configuration with four silicon elements housed in an R-PDSO-G4 package. The device supports a maximum average output current of 2 A and offers a repetitive peak reverse voltage rating of 100 V. Key electrical characteristics include a maximum forward voltage of 0.85 V and a non-repetitive peak forward surge current capability of 50 A. The component operates within a temperature range of -55 °C to 125 °C.
Feature Summary
- Low power loss and high efficiency design
- High surge current capability
- Ultra-high-speed switching performance
- Guarding for overvoltage protection
Applications
- Efficiency-optimized rectification circuits
- Low voltage power supply applications
- Free wheeling diode implementations
Procurement Notes
Verify the specific datasheet version and RoHS compliance status directly with Comchip Technology or authorized distributors before procurement. Confirm that the R-PDSO-G4 package dimensions match your PCB footprint requirements. Ensure the operating environment stays within the specified -55 °C to 125 °C junction temperature limits to maintain reliability.
Selection Notes
Select this component when a low-profile surface mount Schottky bridge rectifier is required for high-efficiency applications. The 2 A current rating and 100 V reverse voltage make it suitable for compact power designs. Consider the 0.85 V forward voltage drop for thermal management calculations in space-constrained enclosures.
Part Context
This part belongs to the CDBA series of low profile Schottky barrier rectifiers from Comchip Technology. These devices utilize silicon epitaxial planar chip technology with metal silicon junctions. The series is designed to optimize board space while providing excellent power dissipation and better reverse leakage current characteristics compared to standard packages.
Replacement Considerations
Cross-reference with other Comchip CDBA series variants such as CDBA260LR-HF or CDBA340LR-HF if different voltage or current ratings are needed. Verify pinout compatibility and package dimensions (R-PDSO-G4) before substituting with components from other manufacturers.
