CDBF0130-HF

Overview

The CDBF0130-HF is a silicon Schottky barrier rectifier manufactured by Comchip Technology, designed for surface-mount applications in the 0603 (1608 metric) package. It features a single diode configuration with a maximum repetitive reverse voltage of 35 V and an average forward current rating of 100 mA. The device exhibits a low forward voltage drop of 440 mV at rated current and supports a forward surge current of 1 A. It operates reliably up to a maximum junction temperature of +125 °C, offering low leakage current characteristics suitable for high-frequency switching and polarity protection circuits.

Feature Summary

• Utilizes silicon epitaxial planar technology for fast switching performance
• Low forward voltage drop minimizes power loss in DC-DC converters
• Lead-free construction compliant with RoHS directives

Applications

• Polarity protection in portable electronic devices
• Free-wheeling diodes in low-voltage DC-DC converters
• Clamping diodes in RF and microwave circuits

Procurement Notes

Verify the specific suffix 'HF' confirms lead-free and halogen-free compliance as per manufacturer specifications. Ensure the ordering part number matches the required 0603 package dimensions. Confirm that the 35 V reverse voltage rating aligns with the circuit's peak inverse voltage requirements to prevent breakdown during operation.

Selection Notes

Select this component when space constraints necessitate an 0603 SMD footprint for Schottky rectification. It is appropriate for low-current applications requiring 100 mA continuous handling. Consider the 440 mV forward voltage drop against efficiency needs. Compare with the CDBU0130-HF if a different package variant is preferred for the same electrical ratings.

Part Context

This component belongs to the CDBF0130 series of small-signal Schottky diodes from Comchip Technology. It shares core electrical specifications with the CDBU0130-HF but differs in physical packaging. The series is engineered for compact consumer electronics and industrial control systems where miniaturization and thermal stability are critical design parameters.

Replacement Considerations

The CDBU0130-HF serves as a functional equivalent within the same product family, offering identical electrical ratings in a different package style. Verify pinout compatibility and thermal dissipation capabilities before substituting in existing PCB layouts.
