CDBF0330-HF

Overview

The CDBF0330-HF is a single Schottky barrier rectifier diode manufactured by Comchip Technology. It features a maximum repetitive reverse voltage (Vrrm) of 30 V and an average forward rectified current (Io) of 350 mA. The device exhibits a maximum forward voltage drop (Vf) of 600 mV at 200 mA and a low reverse leakage current (Ir) of 5 µA. Designed for surface mount applications, it is housed in the compact 1005 (2512 metric) package. The component supports a maximum operating temperature of +125 °C and complies with RoHS standards.

Feature Summary

• Schottky barrier technology ensures low forward voltage drop and fast switching speeds
• Compact 1005 surface-mount package facilitates high-density PCB layouts
• Halogen-free construction meets environmental compliance requirements

Applications

• DC/DC converter circuits
• General-purpose power supply rectification
• Low-voltage signal detection

Procurement Notes

Verify the specific datasheet revision to confirm electrical tolerances and packaging details before integration. Ensure the design accounts for thermal dissipation within the 1005 footprint limits. Confirm that the 30 V reverse voltage rating provides sufficient margin for the target circuit's peak inverse voltage conditions to prevent breakdown during operation.

Selection Notes

Select this component when a low-profile Schottky diode is required for 30 V applications. The 350 mA current rating suits moderate power levels where efficiency is prioritized over high-current capacity. Compare the 600 mV forward voltage against alternatives if minimizing conduction loss is critical. Ensure the SMD package aligns with existing assembly equipment capabilities.

Part Context

This part belongs to Comchip Technology's CDBF series of surface-mount Schottky rectifiers. The series offers various voltage and current combinations optimized for modern electronics. The CDBF0330-HF specifically targets applications requiring reliable rectification in space-constrained designs. It represents a standard solution for low-voltage DC power management systems.

Replacement Considerations

Cross-reference with other 30 V, 350 mA Schottky diodes in the 1005 package. Verify pinout compatibility and thermal characteristics. Ensure substitute parts meet the same RoHS and halogen-free specifications.
