Overview
The CDBA320-G is a Schottky barrier rectifier manufactured by Comchip Technology, designed for surface mount applications. It features a DO-214AC (SMA) molded plastic case with a maximum average forward current of 3.0 A and a maximum repetitive peak reverse voltage of 20 V. The device exhibits a low instantaneous forward voltage of 0.50 V at 3.0 A and a maximum DC reverse current of 10 mA at rated blocking voltage. It supports a peak surge forward current of 80 A under JEDEC testing conditions.
Feature Summary
- Low forward voltage drop for improved efficiency
- Built-in strain relief for mechanical stability
- Plastic package classified as UL flammability rating 94V-0
- Halogen-free construction
Applications
- Surface mount power supply circuits
- Free-wheeling diodes in inductive loads
- Polarity protection applications
Procurement Notes
Verify the specific part number against official manufacturer documentation to confirm electrical ratings and physical dimensions. Ensure compliance with RoHS and Halogen-Free requirements if mandated by project specifications. Confirm that the DO-214AC package matches the intended PCB footprint and reflow soldering profile.
Selection Notes
Select this component when a 3 A continuous current rating and 20 V reverse voltage are required in a compact SMD form factor. Consider the low forward voltage characteristic for minimizing conduction losses. Verify thermal resistance parameters against the expected ambient temperature and copper pad area on the printed circuit board.
Part Context
This component belongs to the CDBA series of SMD Schottky Barrier Rectifiers from Comchip Technology. The series covers reverse voltages ranging from 20 V to 100 V while maintaining a consistent 3.0 A forward current capability across variants such as the CDBA340-G through CDBA3100-G.
Replacement Considerations
Cross-reference with other manufacturers offering DO-214AC packaged Schottky diodes with equivalent 3 A and 20 V ratings. Verify pinout polarity and forward voltage characteristics to ensure functional compatibility.
