CDBER0130L-HF

Overview

The CDBER0130L-HF is a Schottky barrier diode manufactured by Comchip Technology, designed for surface-mount applications. It features a silicon epitaxial planar construction within a DFN package. Key electrical specifications include a maximum repetitive reverse voltage of 30 V and an average forward current rating of 100 mA. The device exhibits a low forward voltage drop, specified at 250 mV under typical conditions, and maintains a low reverse leakage current of 10 µA. It supports a forward surge current of 3 A and operates reliably across a junction temperature range from -40°C to +125°C.

Feature Summary

• Low forward voltage drop for improved power efficiency
• Fast switching capability with minimal reverse recovery charge
• Silicon epitaxial planar chip technology for reliability
• RoHS compliant and lead-free manufacturing

Applications

• Polarity protection circuits
• Low voltage high frequency inverters
• Free wheeling diodes in DC-DC converters
• General purpose rectification in portable devices

Procurement Notes

Verify the specific package variant, as the CDBER series utilizes a DFN footprint distinct from other SMD packages like SOD-923F or SOD-123F. Confirm RoHS compliance status directly with the manufacturer or authorized distributors, as regulatory declarations may vary by production batch. Ensure the ordering suffix matches the required tape and reel configuration for automated assembly processes.

Selection Notes

Select this component when a compact surface-mount solution is required for low-voltage rectification. The 100 mA current rating suits signal-level or low-power applications rather than high-current power stages. Compare the 30 V reverse voltage limit against peak circuit transients to ensure adequate margin. Consider the thermal performance of the DFN package if operating near the upper temperature limits.

Part Context

This part belongs to the CDBER series of Schottky diodes from Comchip Technology, which focuses on small-signal rectification. The series offers various voltage and current combinations tailored for space-constrained electronics. The CDBER0130L-HF specifically addresses needs for low-profile packaging while maintaining standard Schottky characteristics for efficient power management in consumer and industrial gadgets.

Replacement Considerations

Direct substitutes must match the 30 V / 100 mA rating and DFN package outline. Verify pinout compatibility before substitution. Other Comchip models in the CDBQC or CDBQR series offer similar electrical specs but utilize different footprints such as SOD-923F or 0402, requiring PCB layout adjustments.
