CDBM120L-HF

Overview

The CDBM120L-HF is a single-phase Schottky barrier rectifier manufactured by Comchip Technology. It features a Mini-SMA (SOD-123) surface-mount package designed for low-profile applications. The device provides a maximum repetitive reverse voltage of 20 V and an average forward current rating of 1 A. Key electrical characteristics include a low forward voltage drop and high surge current capability, making it suitable for efficient power conversion in compact electronic designs.

Feature Summary

• Utilizes silicon epitaxial planar chip technology with metal-silicon junction construction
• Features ultra-high-speed switching capabilities for improved efficiency
• Offers guarding against overvoltage conditions through robust reverse leakage performance
• Designed with a low-profile package to optimize printed circuit board space

Applications

• Low voltage DC-DC converter circuits
• Power supply freewheeling diodes
• Reverse polarity protection in portable devices
• High-frequency rectification in consumer electronics

Procurement Notes

Verify the specific ordering suffix and tape-and-reel quantity requirements before procurement. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer. Ensure storage conditions adhere to moisture sensitivity level guidelines to maintain component integrity prior to assembly.

Selection Notes

Select this component when a 20 V reverse voltage rating and 1 A continuous current are required in a Mini-SMA footprint. Consider its low forward voltage characteristics for efficiency-critical low-voltage applications. Evaluate thermal resistance parameters if operating near maximum junction temperature limits in confined spaces.

Part Context

This part belongs to Comchip Technology's CDBM series of low-profile SMD Schottky barrier rectifiers. The series emphasizes batch process design for consistent thermal resistance and reverse leakage current performance. It serves as a surface-mount alternative to larger through-hole rectifiers in modern miniaturized electronics.

Replacement Considerations

Direct substitutes within the same voltage and current ratings from other manufacturers should be evaluated for pin compatibility and forward voltage specifications. Verify that any replacement maintains the Mini-SMA package dimensions and thermal characteristics to ensure mechanical fit.
