CDBB560-HF

Overview

The CDBB560-HF is a surface-mount Schottky barrier rectifier manufactured by Comchip Technology. It features a DO-214AA (SMB) package and supports a maximum repetitive peak reverse voltage of 60 V with a DC blocking voltage of 60 V. The device handles a continuous forward current of 5.0 A and withstands a forward surge current of 125 A. Key electrical characteristics include a maximum instantaneous forward voltage of 0.75 V at 5.0 A, a reverse current of 0.5 mA, and a junction-to-ambient thermal resistance of 38 °C/W. Operating temperatures range from -50 °C to +150 °C.

Feature Summary

• Ultra high-speed switching capability for efficient power conversion.
• Guard ring structure provides enhanced overvoltage protection.
• Low profile design optimizes board space utilization.
• Silicon epitaxial planar chip construction ensures reliability.

Applications

• Low profile surface mount applications requiring optimized board space.
• High efficiency power supply circuits utilizing low power loss components.
• Overvoltage protection guarding in electronic systems.

Procurement Notes

Verify the specific part number suffix against official manufacturer documentation to confirm exact specifications. Ensure compliance with RoHS and Halogen-free requirements as stated in the datasheet. Confirm packaging details such as reel size and pitch before ordering. Cross-reference the marking code SS56 with the component body to validate authenticity upon receipt.

Selection Notes

Select this component for applications requiring a 60 V reverse voltage rating and 5 A forward current capacity in a SMB package. Consider the 0.75 V forward voltage drop for efficiency calculations. Evaluate thermal management needs based on the 38 °C/W junction-to-ambient thermal resistance. Compare surge current capabilities against circuit transient requirements.
