Overview
The CDBD650-G is a Chip Schottky Barrier Rectifier manufactured by Comchip Technology, housed in a TO-252/DPAK surface-mount package. It features a repetitive peak reverse voltage of 50 V and a continuous forward rectified current of 6.0 A. The maximum forward voltage drop is 0.85 V at rated current, with a peak forward surge current capability of 100 A for an 8.3 ms half-sine wave. Thermal resistance from junction to case is 3.0 °C/W, while junction-to-ambient resistance is 56 °C/W. The device operates within a temperature range of -55 °C to +150 °C for the junction and -65 °C to +175 °C for storage.
Feature Summary
- Utilizes silicon epitaxial planar chip technology with metal silicon junctions for ultra high-speed switching.
- Incorporates batch process design to ensure excellent power dissipation and optimized thermal resistance.
- Provides guarding for overvoltage protection with low forward voltage drop and high efficiency.
- Features lead-free construction compliant with environmental standards.
Applications
- Low profile surface mounted applications requiring board space optimization.
- High efficiency power conversion circuits utilizing Schottky barrier characteristics.
- Overvoltage protection scenarios in electronic systems.
Procurement Notes
Verify the specific part number against official manufacturer documentation to confirm electrical ratings and package dimensions. Ensure compatibility with standard TO-252/DPAK footprints during PCB layout. Confirm RoHS compliance status through current datasheets as manufacturing processes may evolve. Cross-reference thermal management requirements with system constraints before integration.
Selection Notes
Select this component when a 6.0 A continuous current rating and 50 V reverse voltage are required in a DPAK package. Evaluate thermal resistance values against heat sink or board copper area capabilities. Consider the low forward voltage drop for efficiency gains in low-voltage DC applications. Verify surge current tolerance matches potential transient loads in the target circuit design.
Part Context
This device belongs to the CDBD series of Chip Schottky Barrier Rectifiers from Comchip Technology. The series spans reverse voltages from 20 V to 100 V with a consistent 6.0 A forward current rating. All variants share the same TO-252/DPAK mechanical outline and general feature set, differing primarily in breakdown voltage specifications.
Replacement Considerations
Compatible substitutes include other 6.0 A, 50 V Schottky rectifiers in the TO-252/DPAK package. Verify that replacement parts match the 0.85 V maximum forward voltage and 100 A surge current ratings. Ensure thermal resistance parameters are equivalent to maintain system reliability.
