Overview
The CDBCT320-HF is a surface-mount Schottky barrier rectifier manufactured by Comchip Technology. It features an average forward current of 3 A and a repetitive peak reverse voltage of 20 V. The device utilizes a leadless 3220 package with pure tin-plated terminals. Electrical characteristics include a maximum reverse peak reverse current of 0.5 mA and a typical junction capacitance of 17 pF at 4 V reverse bias. Thermal resistance from junction to ambient is specified at 55 °C/W, while the junction-to-lead thermal resistance is 0.33 °C/W.
Feature Summary
- Leadless chip form factor designed to prevent lead damage during assembly.
- Low power loss and high efficiency resulting from low forward voltage drop.
- High current capability suitable for demanding power applications.
- Halogen-free plastic package with UL 94V-0 flammability rating.
Applications
- General purpose rectification in power supply circuits.
- Freewheeling diodes in DC-DC converter topologies.
- Protection against reverse polarity in electronic systems.
Procurement Notes
Verify component authenticity through official manufacturer channels or authorized distributors. Confirm RoHS compliance status as indicated on the datasheet. Ensure storage conditions align with semiconductor handling standards to maintain terminal solderability and package integrity prior to assembly.
Selection Notes
Select this component when a 3 A continuous current rating and 20 V blocking voltage are required in a compact surface-mount footprint. Consider the 3220 package dimensions for PCB layout constraints. Evaluate thermal management requirements based on the specified junction-to-ambient thermal resistance values under expected operating loads.
Part Context
This part belongs to the CDBCT series of SMD Schottky Barrier Diodes from Comchip Technology. The series includes variants with different reverse voltage ratings, such as 40 V, 60 V, and 100 V options, all sharing similar current capabilities and package styles. The CDBCT320-HF specifically denotes the 20 V variant within this family.
Replacement Considerations
Compatible substitutes within the same series include CDBCT340-HF (40 V), CDBCT360-HF (60 V), and CDBCT3100-HF (100 V). These parts share identical mechanical dimensions and current ratings but differ in maximum reverse voltage specifications.
