CDBER43

Overview

The CDBER43 is a silicon Schottky barrier rectifier diode manufactured by Comchip Technology. It features a single-phase, one-element configuration housed in an SOD-723F (0503) surface-mount package. The device is rated for a maximum repetitive reverse voltage of 30V and a continuous forward current of 200mA. Key electrical characteristics include a maximum forward voltage drop of 1V at 200mA and a maximum reverse leakage current of 500nA.

Feature Summary

• Utilizes silicon epitaxial planar chip technology with a metal-silicon junction for high-efficiency rectification.
• Provides ultra-high-speed switching capabilities suitable for low-power applications.
• Offers guarding against overvoltage conditions through its Schottky barrier design.

Applications

• Low-profile surface-mounted power supply circuits
• High-frequency signal rectification
• Overvoltage protection in sensitive electronic systems

Procurement Notes

Verify the specific ordering suffix to ensure the correct packaging format matches your assembly requirements. Confirm that the component meets the environmental standards required for your final product, such as MIL-STD-19500/228 compliance if applicable. Cross-reference the datasheet revision date to ensure technical specifications have not changed since your initial design phase.

Selection Notes

Select this component when a compact surface-mount solution is required for low-voltage, low-current rectification tasks. The SOD-723F package allows for optimized board space utilization compared to larger standard packages. Ensure the operating temperature range of -55°C to +125°C aligns with your system's thermal environment and that the 30V rating provides sufficient headroom for your circuit's peak reverse voltage.

Part Context

This part belongs to the Comchip Technology series of small-signal Schottky diodes designed for surface-mount applications. These devices are engineered to offer better reverse leakage current and thermal resistance compared to standard alternatives. The series emphasizes low profile dimensions to facilitate dense PCB layouts while maintaining reliable performance in consumer and industrial electronics.

Replacement Considerations

Direct substitutes must match the 30V reverse voltage, 200mA forward current, and SOD-723F footprint. Verify pinout compatibility and forward voltage characteristics to ensure circuit performance remains within acceptable limits without redesigning the surrounding components.
