Overview
The CDBA3150-HF is a surface-mount Schottky barrier rectifier manufactured by Comchip Technology. It features a DO-214AC (SMA) package and supports a maximum repetitive peak reverse voltage of 150 V with an average forward rectified current of 3.0 A. The device exhibits a maximum instantaneous forward voltage of 0.90 V at 3.0 A, a maximum reverse leakage current of 0.5 mA at 25°C, and a thermal resistance of 55°C/W. It operates within a junction temperature range of -50 to +175°C and withstands a peak forward surge current of 70 A.
Feature Summary
- Ultra high-speed switching capability for efficient power conversion
- Guard ring structure designed for overvoltage protection
- Low profile surface mount design to optimize board space utilization
Applications
- Low profile surface mount applications requiring optimized board space
- High efficiency power supply circuits
- General purpose rectification in electronic equipment
Procurement Notes
Verify the specific part number against official manufacturer documentation to confirm electrical ratings and package dimensions. Ensure compliance with RoHS and Halogen-free requirements as specified in the datasheet. Confirm that the ordering suffix matches the intended voltage rating and packaging configuration before procurement.
Selection Notes
Select this component for applications requiring a 3.0 A current rating and 150 V reverse voltage blocking capability. Consider the DO-214AC package for standard surface-mount assembly processes. Evaluate the thermal resistance and operating temperature range to ensure suitability for the intended environmental conditions and heat dissipation requirements.
Part Context
This component belongs to the CDBA series of SMD Schottky Barrier Rectifiers from Comchip Technology. The series includes variants with different reverse voltage ratings, such as the CDBA3200-HF, which shares similar physical characteristics but offers a higher voltage rating of 200 V. These devices are designed for low power loss and high efficiency in compact electronic designs.
Replacement Considerations
The CDBA3200-HF is a related variant within the same series offering a 200 V reverse voltage rating instead of 150 V. Verify compatibility regarding voltage derating and physical footprint when considering substitution.
