Overview
The CDBD620-G is a silicon epitaxial planar chip Schottky barrier rectifier manufactured by Comchip Technology. It features a DPAK (TO-252) surface-mount package with a continuous forward current rating of 6.0 A and a repetitive peak reverse voltage of 20 V. The device exhibits a maximum forward voltage drop of 0.75 V at rated current and supports a surge current of 75 A. Thermal performance includes a junction-to-case resistance of 4.0 °C/W and a junction-to-ambient resistance of 62 °C/W, operating within a temperature range of -55°C to +175°C.
Feature Summary
- Utilizes guardring technology for enhanced overvoltage protection stability.
- Features ultra-high-speed switching characteristics suitable for high-frequency applications.
- Employs a low-profile surface mount design to optimize printed circuit board space utilization.
Applications
- High-efficiency power supply circuits
- Free-wheeling diode implementations in inverters
- Polarity protection systems
Procurement Notes
Verify the specific part number against official manufacturer documentation to confirm electrical ratings and package dimensions. Ensure compliance with RoHS directives and MIL-STD environmental standards required for your application. Cross-reference datasheet thermal derating curves for accurate system design.
Selection Notes
Select this component for designs requiring robust high-current handling in a compact surface-mount footprint. Evaluate the 0.75 V forward voltage drop against system efficiency targets. Confirm that the 20 V reverse voltage rating provides adequate margin for the intended circuit's peak inverse voltage conditions.
Part Context
This device belongs to the CDBD6 series of Chip Schottky Barrier Rectifiers from Comchip Technology. The series spans various voltage ratings from 20 V to 100 V while maintaining a consistent 6.0 A current capability. All variants share the same DPAK mechanical outline and general feature set.
Replacement Considerations
Compatible substitutes within the same series include CDBD630-G, CDBD640-G, CDBD650-G, CDBD660-G, CDBD680-G, and CDBD6100-G, provided their respective reverse voltage ratings meet or exceed the circuit requirements.
