Overview
The CDBB1200LR-HF is a Schottky barrier rectifier manufactured by Comchip Technology. It features a maximum repetitive reverse voltage of 200 V and a forward current rating of 1 A. The device utilizes a DO-214AA (SMB) surface-mount package. Key electrical characteristics include a maximum forward voltage drop of 0.85 V at rated current and a low reverse leakage current. The component is designed for high-efficiency power conversion applications, offering fast switching capabilities and robust thermal performance within an operating temperature range of -55°C to +175°C.
Feature Summary
- Schottky barrier construction for ultra-fast switching and minimal reverse recovery charge
- Low forward voltage drop to enhance overall system efficiency and reduce power loss
- High surge current capability to withstand transient overloads
- Lead-free finish compliant with environmental standards
Applications
- DC-DC converter output rectification
- Power supply freewheeling diodes
- Reverse polarity protection circuits
- Clamping diodes in high-frequency switching applications
Procurement Notes
Verify the specific suffix 'LR' against the manufacturer's latest datasheet to confirm exact packaging and compliance status. Ensure the DO-214AA footprint matches the design layout. Confirm RoHS transition status if strict regulatory compliance is required for the target market.
Selection Notes
Select this component when a 200V blocking voltage and 1A continuous current are required in a compact SMB package. Consider the low forward voltage for efficiency-critical designs. Compare thermal resistance values against the PCB copper area available for heat dissipation to ensure junction temperature remains within limits under full load conditions.
Part Context
This part belongs to Comchip Technology's CDBB series of surface-mount Schottky rectifiers. The series is characterized by silicon epitaxial planar chips and metal-silicon junctions. These devices are engineered for general-purpose rectification in consumer electronics, telecommunications, and industrial power supplies where space constraints and switching speed are critical factors.
Replacement Considerations
The CDBB1200-HF is a related variant within the same product family. Verify pinout compatibility and package dimensions before substitution. Ensure that any alternative Schottky diode meets or exceeds the 200V reverse voltage and 1A forward current ratings while maintaining similar forward voltage characteristics.
