Overview
The CDBB3200LR-HF is a Schottky barrier rectifier manufactured by Comchip Technology. It features a single diode configuration in an SMD/SMT DO-214AA (SMB) package. The device supports a maximum average forward rectified current of 3A and a repetitive peak reverse voltage of 200V. Key electrical parameters include a maximum DC reverse leakage current of 500µA at rated voltage, a maximum forward voltage drop of 900mV at 3A, and a peak forward surge current rating of 70A. It operates within a junction temperature range of -50°C to +175°C.
Feature Summary
- Low forward voltage characteristics for improved efficiency
- Low reverse leakage current performance
- High thermal stability with extended operating temperature range
Applications
- DC-DC converters
- Free-wheeling diodes
- Polarity protection circuits
- Power supply rectification
Procurement Notes
Verify the specific suffix 'LR' against the official datasheet to confirm low leakage specifications. Ensure the ordering part number matches the required RoHS compliance status. Cross-reference the package marking code with the manufacturer's guide to prevent counterfeit identification during assembly.
Selection Notes
Select this component when a 200V blocking capability and 3A continuous current are required in a compact SMB footprint. Consider the 900mV forward voltage drop for power loss calculations. Verify that the 500µA leakage specification meets the standby power requirements of the target application design.
Part Context
This part belongs to the CDBB series of surface mount Schottky rectifiers from Comchip Technology. The series utilizes silicon planar technology optimized for high-speed switching applications. The LR designation typically indicates specific low-leakage variants within the standard product line.
Replacement Considerations
Consult official substitution guides for equivalent parts with matching 200V/3A ratings and DO-214AA packages. Verify pinout compatibility and thermal resistance values before replacing.
