CDBB2150-HF

Overview

The CDBB2150-HF is a Schottky Barrier Rectifier manufactured by Comchip Technology, designed for low-profile surface-mounted applications to optimize board space. It features a silicon epitaxial planar chip with a metal-silicon junction in an SMB (DO-214AA) package. Key electrical parameters include a repetitive reverse voltage of 150 V and a forward current of 2 A. The device exhibits a maximum forward voltage drop of 1.05 V at rated current and a reverse leakage current of 5 µA. It supports a forward surge current of 60 A and operates within a temperature range of -55 °C to +175 °C.

Feature Summary

• Batch process design providing excellent power dissipation and improved thermal resistance
• Ultra high-speed switching capability with low forward voltage drop for high efficiency
• Low profile package that is significantly thinner than standard SOD-123 dimensions
• Guarding functionality for overvoltage protection with high surge current capability

Applications

• Low profile surface mounted rectification in compact electronic designs
• Power supply circuits requiring high efficiency and low power loss
• Overvoltage protection in consumer electronics and industrial equipment
