Overview
The CDBF0320-HF is a surface-mount Schottky barrier rectifier manufactured by Comchip Technology. It features a maximum repetitive peak reverse voltage of 20 V and an average forward rectified current of 350 mA. The device exhibits a low forward voltage drop of 600 mV at 200 mA and a reverse recovery time of 6.4 ns. Capacitance is specified as 50 pF at 0 V reverse bias and 1 MHz frequency. The component is housed in a leadless, extremely thin SOD-323 package suitable for small surface mounting applications.
Feature Summary
- Schottky barrier technology ensures low forward voltage drop and high efficiency
- Ultra-fast reverse recovery characteristics minimize switching losses
- Leadless, extremely thin package design optimizes board space utilization
Applications
- High-frequency DC-DC converter circuits
- Low-voltage power supply rectification
- Surface-mount assembly for compact electronic devices
Procurement Notes
Verify the specific ordering suffix to confirm packaging configuration, such as tape and reel or cut tape options. Confirm compliance with RoHS directives and halogen-free status prior to procurement. Ensure the selected variant matches the required thermal management capabilities for the intended operating environment.
Selection Notes
Select this component for applications requiring low forward voltage and fast switching speeds within a 20 V reverse voltage limit. The SOD-323 package is appropriate for automated surface-mount processes where minimal footprint is critical. Evaluate thermal performance against the expected ambient temperature and current load conditions.
Part Context
This part belongs to Comchip Technology's SMD Schottky diode portfolio, designed for efficient power conversion in compact electronics. The series emphasizes low profile and leadless construction to facilitate high-speed surface-mount manufacturing processes while maintaining reliable electrical performance under standard operating conditions.
Replacement Considerations
Cross-reference with other 20 V, 350 mA Schottky diodes in the SOD-323 package. Verify pinout compatibility and ensure equivalent reverse recovery time and forward voltage specifications are met to maintain circuit performance integrity.
