CDBB3150LR-HF

Overview

The CDBB3150LR-HF is a Schottky Barrier Rectifier manufactured by Comchip Technology. It features a repetitive reverse voltage of 150V and an average forward current of 3A. The device utilizes a DO-201AD (DO-4) axial-leaded package. Key electrical characteristics include a low forward voltage drop and high surge capability, designed for efficient power conversion in surface-mounted or through-hole applications requiring robust rectification.

Feature Summary

• Schottky barrier construction for ultra-fast switching
• Low forward voltage drop for high efficiency
• High surge current capability
• Guarding against overvoltage conditions

Applications

• DC-DC converters
• Power supply rectification
• Free-wheeling diodes in inductive circuits

Procurement Notes

Verify the specific suffix 'LR' against the official Comchip Technology datasheet to confirm lead-free status and RoHS compliance details. Ensure the DO-201AD package dimensions match the target PCB footprint requirements before finalizing procurement orders.

Selection Notes

Select this component when a 150V blocking voltage and 3A continuous current rating are required. The Schottky technology offers lower power loss compared to standard PN junction diodes, making it suitable for high-frequency switching applications where thermal management is critical.

Part Context

Comchip Technology produces discrete semiconductors including Schottky diodes. The CDBB series represents their axial-leaded Schottky rectifiers. This model falls within the company's portfolio of components designed for industrial and consumer electronics markets.

Replacement Considerations
