Overview
The CDBQR54-HF is a surface-mount Schottky barrier rectifier manufactured by Comchip Technology. It features an average forward current of 200 mA and a maximum repetitive peak reverse voltage of 30 V. The device utilizes a DFN or SOD-923F-2 package, measuring approximately 1.05 mm in length, 0.65 mm in width, and 0.55 mm in height. Key electrical characteristics include a maximum forward voltage of 0.24 V at rated current and a maximum non-repetitive peak forward surge current of 0.6 A. The component supports a maximum operating temperature of 125 °C.
Feature Summary
- Schottky barrier construction for low forward voltage drop
- Small footprint DFN/SOD-923F-2 package design
- High efficiency operation with minimal power loss
Applications
- Portable electronic devices requiring compact rectification
- Power management circuits in mobile communications
- DC-DC converter output rectification
Procurement Notes
Verify the specific package variant (DFN vs. SOD-923F) against the schematic, as both are referenced. Confirm RoHS compliance status directly with the manufacturer, as documentation indicates transition periods. Ensure the 30V reverse voltage rating meets the circuit's peak inverse voltage requirements to prevent breakdown during operation.
Selection Notes
Select this component for applications prioritizing small board space over high current handling. The 200 mA limit restricts usage to low-power signal or supply paths. Compare the 0.24 V forward voltage against alternatives if minimizing conduction loss is critical. Verify thermal dissipation capabilities within the plastic epoxy package for the intended ambient conditions.
Part Context
This part belongs to Comchip Technology's line of small-signal Schottky diodes designed for surface mount technology. It serves as a low-voltage, low-current alternative to larger rectifiers, fitting into ultra-thin consumer electronics. The series focuses on reducing parasitic effects through its compact physical dimensions while maintaining standard silicon junction reliability.
Replacement Considerations
Check for direct pin-compatible substitutes from other manufacturers offering identical 200 mA/30V ratings in SOD-923F packages. Ensure any replacement maintains the same maximum operating temperature of 125 °C and similar forward voltage characteristics to preserve circuit performance.
