CDBMS1200-HF

Overview

The CDBMS1200-HF is a Schottky barrier rectifier manufactured by Comchip Technology, designed for low-profile surface-mount applications. It utilizes silicon epitaxial planar chip technology with a metal-silicon junction to ensure ultra-high-speed switching and high efficiency. The device features a SOD-123F-2 package configuration, supporting a maximum repetitive reverse voltage of 200 V and an average forward current of 1 A. Key electrical characteristics include a maximum forward voltage of 920 mV at rated current and a maximum reverse leakage current of 10 mA. It operates within a temperature range of -55°C to +150°C and offers a high surge current capability of 30 A.

Feature Summary

• Ultra-high-speed switching capability with soft and fast transition characteristics
• Low profile package design optimized for board space conservation
• High surge current capability for robust transient protection
• Guarding functionality against overvoltage conditions

Applications

• Automotive electronics requiring AEC-Q101 qualification
• DC-DC converters and power supply units
• Free-wheeling diodes in inductive load circuits
• Reverse polarity protection in battery-powered devices

Procurement Notes

Verify the specific suffix 'HF' indicates halogen-free compliance as per manufacturer standards. Confirm the package variant matches the required footprint, as SOD-123F dimensions differ from standard SOD-123. Ensure procurement channels provide valid RoHS documentation. Cross-reference the datasheet revision date to confirm parameter accuracy. Validate that the component meets the specific thermal resistance requirements of the target application.

Selection Notes

Select this component when a low forward voltage drop is critical for system efficiency. The 200 V rating suits intermediate voltage bus applications. Consider the SOD-123F package for tight spatial constraints compared to larger packages. Evaluate the 1 A continuous current limit against peak load requirements. The AEC-Q101 qualification makes it suitable for automotive environments where reliability under thermal stress is mandatory.

Part Context

This part belongs to the CDBMS series of Schottky barrier rectifiers from Comchip Technology. The series emphasizes batch process design for consistent reverse leakage current and thermal performance. It shares architectural similarities with other low-profile SMD rectifiers but distinguishes itself through specific voltage and current ratings tailored for compact power management solutions.

Replacement Considerations

Direct substitutes must match the 200 V reverse voltage, 1 A forward current, and SOD-123F-2 package. Verify equivalent forward voltage and reverse leakage specifications to maintain circuit performance. Check if alternative parts offer comparable AEC-Q101 certification if automotive use is intended.
