CDBDSC8650-G

Overview

The CDBDSC8650-G is a Silicon Carbide (SiC) Schottky barrier rectifier manufactured by Comchip Technology. It features a single diode configuration housed in a surface-mount DPAK package. The device supports a repetitive reverse voltage of 650 V and an average forward current of 25.5 A. Key electrical parameters include a maximum forward voltage of 1.45 V. This component is designed for high-efficiency power conversion applications requiring robust thermal performance and low reverse leakage characteristics typical of SiC technology.

Feature Summary

• Utilizes Silicon Carbide material for superior high-temperature operation and efficiency
• Low forward voltage drop reduces conduction losses
• Ultra-fast switching capability minimizes reverse recovery charge
• Lead-free construction compliant with environmental standards

Applications

• High-frequency DC-DC converters
• Power factor correction circuits
• Uninterruptible power supplies (UPS)
• Solar inverters and motor drives

Procurement Notes

Verify the specific datasheet version to confirm exact thermal resistance values and pinout configurations, as manufacturing updates may occur. Ensure the ordering part number includes the correct suffix if specific tape-and-reel packaging is required rather than tube packaging. Cross-reference the manufacturer's official documentation for any changes in RoHS compliance status or lead finish specifications prior to final procurement.

Selection Notes

Select this component when high-temperature stability and reduced switching losses are critical compared to standard silicon diodes. The 650 V rating suits medium-voltage applications, while the 25.5 A current capacity requires adequate heatsinking or PCB copper area for thermal management. Consider the DPAK package size constraints against available board space and mounting requirements for surface-mount assembly processes.

Part Context

This part belongs to Comchip Technology's Silicon Carbide series, which specializes in diodes performing well under high-temperature conditions with ultra-low reverse current. The CDBDSC8650-G represents the company's focus on high-efficiency discrete semiconductors, leveraging patented flat chip manufacturing capabilities to enhance power density and reliability in modern electronic systems.

Replacement Considerations

Direct substitutes must match the 650 V reverse voltage, 25.5 A forward current, and DPAK package. Verify that alternative SiC Schottky diodes offer comparable forward voltage and thermal resistance to maintain circuit efficiency. Check for pin-compatible packages from other manufacturers if supply chain diversification is necessary.
