Overview
The CDBB220-G is a general-purpose rectifier diode manufactured by Comchip Technology. It utilizes a glass-passivated silicon epitaxial planar chip structure housed in an SMB (DO-214AA) surface-mount package. The device is rated for a maximum average forward rectified current of 2.0 A and supports repetitive peak reverse voltages ranging from 50 V to 1000 V, with the specific '20' suffix indicating a 200 V rating. Key electrical characteristics include high surge current capability and low leakage current, designed for efficient performance in compact electronic circuits.
Feature Summary
- Glass-passivated construction ensures stable operation under varying environmental conditions.
- Utilizes silicon epitaxial planar technology for reliable switching performance.
- SMB surface-mount package design facilitates automated pick-and-place assembly.
Applications
- General purpose rectification in surface mount applications
- Polarity protection circuits
- Free wheeling diode configurations
Procurement Notes
Verify the specific voltage code within the part number to confirm the exact Reverse Voltage rating, as the series spans multiple voltage levels. Confirm RoHS compliance status directly with the manufacturer or authorized distributor documentation, as historical data indicates variations across different production batches and revisions of this component family.
Selection Notes
Select this component when a robust 2.0 A surface-mount rectifier is required. Ensure the circuit's peak inverse voltage does not exceed the specific rating indicated by the model suffix. Consider the thermal management requirements associated with the SMB package size during high-current operation.
Part Context
This component belongs to the CGRB series of SMD General Purpose Rectifiers produced by Comchip Technology. The series offers various voltage ratings within the same physical footprint, allowing designers to standardize on a single package type while adjusting voltage specifications through the part number suffix. This approach simplifies supply chain management for mass-produced electronics.
Replacement Considerations
Direct substitutes must match the DO-214AA (SMB) package, 2.0 A current rating, and 200 V reverse voltage specification. Verify that alternative manufacturers offer comparable surge current capabilities and forward voltage drops to ensure circuit compatibility without redesign.
