CDBM2100-HF

Overview

The CDBM2100-HF is a Schottky barrier rectifier manufactured by Comchip Technology, designed for surface-mount applications. It features a Mini-SMA (SOD-123) package and utilizes silicon epitaxial planar chip technology with a metal-silicon junction. The device provides an average forward current of 2A and a repetitive peak reverse voltage of 100V. Key electrical parameters include a maximum forward voltage drop of 0.85V at rated current and a surge forward current capability of 50A. The component operates within a temperature range of -55°C to +150°C.

Feature Summary

• Low forward voltage drop for high efficiency
• Ultra-high-speed switching capability
• Guarding against overvoltage conditions
• Lead-free construction meeting environmental standards

Applications

• DC-DC converters
• Power supply circuits
• Reverse polarity protection

Procurement Notes

Verify the specific datasheet version to confirm RoHS compliance status, as documentation indicates transition periods for certain series. Ensure the ordering suffix matches the required packaging format, such as cut tape or reel, to align with assembly line requirements. Cross-reference the part number with official manufacturer catalogs to validate active lifecycle status before finalizing procurement plans.

Selection Notes

Select this component when a low-profile surface-mount Schottky diode is required for high-efficiency power conversion. The 2A current rating and 100V blocking voltage suit general-purpose rectification tasks. Consider the thermal resistance characteristics and the ability to handle surge currents up to 50A for robust circuit design in space-constrained environments.

Part Context

This part belongs to the Comchip Technology CDBM series of Schottky barrier rectifiers. These devices are characterized by their low profile packages, which offer improved power dissipation compared to standard SOD-123 components. The series emphasizes high current capability and low forward voltage drops, making them suitable for modern compact electronic designs requiring efficient power management.

Replacement Considerations

Direct substitutes must match the 2A forward current, 100V reverse voltage, and SOD-123 package footprint. Verify that alternative Schottky diodes maintain comparable forward voltage specifications and thermal performance to ensure circuit compatibility without redesign.
