Overview
The CDBB3200-HF is a surface-mount Schottky barrier rectifier manufactured by Comchip Technology in the DO-214AA (SMB) package. It features a maximum repetitive peak reverse voltage of 200V and a DC blocking voltage of 200V. The device supports a maximum RMS voltage of 140V and an average forward rectified current of 3.0A at 25°C. Key electrical characteristics include a maximum instantaneous forward voltage of 0.90V at 3.0A, a reverse leakage current of 0.5mA at 25°C, and a junction-to-ambient thermal resistance of 55°C/W. The component operates within a temperature range of -50°C to +175°C.
Feature Summary
- Ultra-high-speed switching capability for efficient power conversion.
- Guard ring structure designed to provide overvoltage protection.
- Low forward voltage drop contributing to high efficiency and low power loss.
- High surge current capability for robust performance under transient conditions.
Applications
- Low profile surface mount applications optimizing board space.
- General purpose rectification in power supply circuits.
- Free-wheeling diodes in inductive load switching.
Procurement Notes
Verify the specific part number CDBB3200-HF against official Comchip Technology datasheets to confirm the 200V reverse voltage rating and SMB package type. Ensure compatibility with RoHS and Halogen-free requirements as specified in the manufacturer documentation. Cross-reference mechanical dimensions and marking codes (SK320) during assembly planning to prevent integration errors.
Selection Notes
Select this component when a 200V reverse voltage rating and 3.0A continuous forward current are required in a compact SMB footprint. Consider the 0.90V forward voltage drop for thermal management calculations. Verify that the operating junction temperature range of -50°C to +175°C meets the environmental demands of the target application circuit design.
Part Context
This device belongs to the CDBB series of SMD Schottky Barrier Rectifiers from Comchip Technology. It shares the same physical package and general feature set as the CDBB3150-HF, differing primarily in its higher voltage rating. The series utilizes silicon epitaxial planar chip technology with metal-silicon junctions for reliable rectification in modern electronic assemblies.
Replacement Considerations
The CDBB3150-HF is a related variant within the same product family but offers a lower 150V reverse voltage rating. Substitution requires verifying that the system's peak reverse voltage does not exceed 150V. No other direct substitute part numbers are documented in the provided source material.
FAQ
What is the marking code for the CDBB3200-HF?
The marking code for the CDBB3200-HF is SK320.
What is the maximum non-repetitive forward surge current?
The maximum non-repetitive forward surge current is 70A for an 8.3ms single half sine-wave pulse.
