CDBB2100LR-HF

Overview

The CDBB2100LR-HF is a Schottky Barrier Rectifier manufactured by Comchip Technology. It features a low forward voltage and low reverse leakage current, designed for surface mount applications in the DO-214AA (SMB) package. The device utilizes silicon epitaxial planar chip technology with a metal-silicon junction. Key electrical parameters include a repetitive peak reverse voltage of 100V, an average forward rectified current of 2A, and a maximum forward voltage drop of 0.85V at rated current. It supports a forward surge current of 60A and operates within a temperature range of -55°C to +150°C.

Feature Summary

• Low profile surface mount construction optimized for high-density PCB layouts
• Ultra-fast switching characteristics with minimal recovery time
• High thermal efficiency due to superior power dissipation capabilities
• Guarding against overvoltage transients through robust surge handling

Applications

• DC-DC converter output rectification
• Free-wheeling diodes in inductive load circuits
• Reverse polarity protection in power supply inputs
• Clamping diodes in high-speed digital signal lines

Procurement Notes

Verify the specific suffix 'LR' against the official Comchip Technology datasheet to confirm lead-free compliance and halogen-free status. Ensure the ordering part number matches the exact voltage and current ratings required for the target circuit design. Cross-reference the package dimensions with the DO-214AA standard to guarantee footprint compatibility during procurement.

Selection Notes

Select this component when a 100V blocking capability and 2A continuous current are required in a compact SMB package. Consider the low forward voltage drop for improved system efficiency in low-voltage DC-DC conversion stages. Evaluate the thermal resistance requirements against the expected ambient operating conditions to ensure reliable performance under sustained load.

Part Context

This part belongs to the CDBB series of Schottky Barrier Rectifiers from Comchip Technology. The series is characterized by its silicon epitaxial planar construction and metal-silicon junction structure. It is designed to replace standard rectifiers in applications requiring faster switching speeds and lower power losses compared to conventional p-n junction diodes.

Replacement Considerations

Direct substitutes must match the 100V VRRM, 2A IO, and DO-214AA package constraints. Verify that alternative Schottky diodes offer comparable forward voltage drops and reverse leakage currents to maintain circuit efficiency. Confirm thermal management requirements align with the replacement component's specifications.
