CDBHM240-HF

Bridge Rectifier Overview

The CDBHM240-HF is a surface-mount Schottky bridge rectifier manufactured by Comchip Technology. It features a single-phase, half-wave configuration with a peak repetitive reverse voltage of 40V and an average rectified output current of 2A. The device utilizes a Schottky barrier chip to achieve low forward voltage drop and high efficiency. Key electrical parameters include a maximum non-repetitive peak forward surge current of 50A and a typical junction capacitance of 10pF per leg. It operates within a temperature range of -55°C to +150°C and is housed in an MBS molded plastic case.

Bridge Rectifier Feature Summary

• Schottky barrier chip construction for low power loss and high efficiency

Bridge Rectifier Procurement Notes

Verify the specific part number suffix against official manufacturer documentation to confirm exact electrical ratings and packaging specifications. Ensure compliance with RoHS and Halogen-free requirements as stated in the datasheet. Confirm thermal resistance values and derating curves are considered for the intended operating environment before finalizing procurement orders.

Bridge Rectifier Selection Notes

Select this component for applications requiring a compact surface-mount Schottky bridge rectifier with a 40V reverse voltage rating and 2A continuous current capability. Consider the MBS package dimensions and suggested pad layout for PCB design compatibility. Evaluate the forward voltage characteristics and thermal performance at expected operating temperatures to ensure system efficiency meets design goals.

Bridge Rectifier Part Context

This component belongs to the CDBHM series of SMD Schottky Bridge Rectifiers from Comchip Technology. The series covers reverse voltage ratings from 20V to 60V, including variants like CDBHM220-HF through CDBHM260-HF. All parts in this family share similar mechanical data, featuring an MBS case and halogen-free construction, while differing primarily in their voltage and current specifications.

Bridge Rectifier Replacement Considerations

Compatible substitutes include other SMD Schottky bridge rectifiers with matching 40V VRRM, 2A IF(AV), and MBS package footprint. Verify pinout compatibility and thermal resistance characteristics when replacing. Ensure the alternative component meets the same RoHS and UL 94V-0 flammability standards.
