Overview
The CDBK0520L-HF is a single Schottky barrier rectifier manufactured by Comchip Technology. It features a maximum repetitive peak reverse voltage of 20 V and an average forward current rating of 500 mA. The device utilizes Silicon technology and is housed in the SOD-123F-2 surface-mount package. Key electrical characteristics include a maximum DC reverse leakage current of 1 µA at 20 V and a typical forward voltage drop of 400 mV at 500 mA. The component supports a peak forward surge current of 5 A and operates within a junction temperature range of -55 °C to +150 °C.
Feature Summary
- Low forward voltage drop for improved power efficiency
- High surge current capability for transient protection
- Lead-free construction compliant with RoHS standards
Applications
- DC-DC converters
- Power supply circuits
- Voltage regulators
- Polarity protection
Procurement Notes
Verify the specific ordering suffix against official manufacturer documentation to ensure correct packaging configuration. Confirm that the requested part number matches the exact electrical specifications required for the design. Check for any recent product change notices or lifecycle status updates directly from Comchip Technology before finalizing procurement plans.
Selection Notes
Select this component when a low-voltage, moderate-current Schottky diode is required in a compact SOD-123F footprint. Ensure the circuit's reverse voltage requirements do not exceed 20 V and the continuous current load remains within the 500 mA limit. Consider the thermal management capabilities of the PCB layout given the small package size.
Part Context
This component belongs to the general Schottky diode category offered by Comchip Technology. It is designed for surface-mount assembly processes. The SOD-123F package provides a balance between current handling capacity and board space efficiency for consumer and industrial electronics.
Replacement Considerations
Consult official cross-reference guides for verified substitutes. Ensure replacement parts match the 20 V reverse voltage, 500 mA forward current, and SOD-123F package dimensions.
