CDBFR0130-HF

Overview

The CDBFR0130-HF is a surface-mount Schottky barrier diode manufactured by Comchip Technology. It features an average forward current of 100 mA and a repetitive peak reverse voltage of 30 V. The device utilizes a 1005 (SOD-323F) package with gold-plated terminals. Electrical characteristics include a maximum forward voltage of 0.44 V at 100 mA DC, a maximum reverse current of 30 µA at 30 V, and a surge peak forward current of 1 A. The component operates within a junction temperature range of -40°C to +125°C and supports a power dissipation of 250 mW.

Feature Summary

• Utilizes majority carrier conduction for low stored charge operation.
• Constructed in an extremely thin molded plastic case designed for small surface mounting.
• Features gold-plated terminals that are solderable per MIL-STD-750 method 2026.

Applications

• Surface-mounted rectification in compact electronic circuits.
• High-frequency switching applications due to low stored charge.
• Power supply input protection stages.

Procurement Notes

Verify the specific revision status against the manufacturer's documentation before integration. Confirm that the 1005 package dimensions align with the target PCB footprint layout. Ensure thermal management strategies account for the 250 mW power dissipation limit under expected operating conditions. Check for halogen-free compliance requirements if applicable to the final assembly standards.

Selection Notes

Select this component when a low-profile SMD Schottky diode is required for 30 V reverse voltage applications. The 100 mA current rating suits low-power signal or power paths. Consider the 0.44 V forward voltage drop for efficiency calculations. The SOD-323F form factor is appropriate for space-constrained designs requiring standard surface mount technology processes.

Part Context

This part belongs to the Comchip Technology SMD Schottky Barrier Diode series. It is distinguished by its halogen-free composition and RoHS compliance. The device is packaged on reels of 4,000 units in a 7-inch reel format. Marking codes such as B3 identify the specific part number on the component body.

Replacement Considerations

Direct substitutes must match the 30 V reverse voltage, 100 mA forward current, and SOD-323F package. Verify equivalent forward voltage and reverse leakage specifications to ensure circuit performance parity.
