Overview
The CDBQR54 is a single Schottky barrier rectifier diode manufactured by Comchip Technology. It features a maximum average forward rectified current of 200 mA and a maximum repetitive peak reverse voltage of 30 V. The device exhibits a low maximum forward voltage drop of 0.24 V and an extremely short maximum non-repetitive peak forward surge current rating of 0.6 A. Key electrical characteristics include a maximum reverse recovery time of 0.005 µs, ensuring rapid switching performance. The component is designed for surface mount applications in the DFN small signal package format.
Feature Summary
- Utilizes Schottky barrier technology to achieve minimal forward voltage drop and negligible reverse recovery charge.
- Engineered for high-speed switching applications due to ultra-fast reverse recovery characteristics.
- Constructed with a compact surface-mount footprint suitable for automated assembly processes.
Applications
- High-frequency rectification in DC-DC converter circuits
- Protection against reverse polarity in low-voltage power supplies
- Clamping and freewheeling functions in switching regulator topologies
Procurement Notes
Verify the specific datasheet version from Comchip Technology to confirm exact mechanical dimensions and thermal resistance values. Ensure that the ordering information matches the required suffixes for RoHS compliance and packaging type. Cross-reference the pinout configuration with the target PCB layout to prevent installation errors during assembly.
Selection Notes
Select this component when circuit requirements demand low forward voltage loss at currents up to 200 mA. The 30 V reverse voltage rating provides adequate margin for standard 5 V or 12 V logic systems. Consider the thermal management capabilities of the DFN package if operating near the maximum junction temperature limit of 125 °C.
Part Context
This device belongs to the Comchip Technology SMD Schottky Barrier Diode family. It is part of a broader range of small-signal rectifiers designed for space-constrained electronic designs. The product line emphasizes efficiency and speed, targeting modern consumer electronics and industrial control applications requiring reliable semiconductor switching solutions.
