CDBB2200-HF

Overview

The CDBB2200-HF is a Schottky barrier rectifier manufactured by Comchip Technology, designed for surface-mount applications. It features a single diode configuration within a DO-214AA (SMB) package. The device utilizes silicon epitaxial planar chip technology with a metal-silicon junction. Key electrical specifications include a maximum repetitive peak reverse voltage of 200V and an average forward rectified current of 2A. The component exhibits a maximum forward voltage drop of 950mV at rated current and a maximum reverse leakage current of 500µA. It supports a forward surge current of 60A and operates reliably across a temperature range from -55°C to +175°C.

Feature Summary

• Low forward voltage drop for improved power efficiency
• High surge current capability for robust transient protection
• Ultra-fast switching characteristics suitable for high-frequency circuits
• Lead-free construction compliant with environmental standards

Applications

• DC-to-DC converter output rectification
• Free-wheeling diodes in low-voltage power supplies
• Reverse polarity protection circuits
• Clamping diodes in high-speed logic interfaces

Procurement Notes

Verify the specific suffix against the manufacturer's latest datasheet to confirm compliance with RoHS directives and halogen-free status. Ensure the ordering part number matches the required packaging format, such as cut tape or reel, as availability may vary by distributor. Cross-reference the DO-214AA footprint dimensions with your PCB layout to guarantee mechanical compatibility during assembly.

Selection Notes

Select this component when a 200V blocking voltage and 2A continuous current rating are required in a compact SMB package. Consider the thermal resistance and operating temperature range if the application involves high ambient heat. Compare the forward voltage drop against alternative Schottky diodes to optimize system efficiency, ensuring the surge current rating exceeds potential inrush requirements.

Part Context

This device belongs to the CDBB series of Schottky barrier rectifiers from Comchip Technology. The series is engineered for general-purpose rectification in space-constrained designs. The CDBB2200-HF variant specifically targets applications requiring moderate voltage blocking capabilities with efficient power conversion characteristics typical of silicon Schottky junctions.

Replacement Considerations

Compatible substitutes include the CDBB2100-HF for lower voltage ratings or the CDBB2300-HF for higher current capacity, provided the package and pinout remain identical. Verify that any replacement maintains the same DO-214AA footprint and meets the original circuit's thermal and electrical constraints.
