CDBM1100-HF

Overview

The CDBM1100-HF is a single silicon Schottky barrier rectifier manufactured by Comchip Technology. It features a maximum repetitive reverse voltage of 100 V and an average forward current rating of 1 A. The device exhibits a maximum forward voltage of 0.85 V at rated current and supports a non-repetitive peak forward surge current of 30 A. Reverse leakage current is specified at a maximum of 200 uA. The component operates within a temperature range from -55 °C to +150 °C junction temperature and is housed in a surface-mount R-PDSO-F2 package.

Feature Summary

• Utilizes silicon Schottky barrier technology for low power loss operation
• Designed for surface mount installation in compact electronic assemblies
• Provides high thermal stability with an extended operating temperature range up to 150 °C

Applications

• General purpose rectification in low voltage DC circuits
• Power supply input protection stages
• Freewheeling diodes in switching regulator topologies

Procurement Notes

Verify the specific datasheet version when sourcing, as parameters such as reverse current may vary between manufacturing batches or regional compliance requirements. Confirm that the R-PDSO-F2 footprint matches the target PCB layout exactly. Ensure the supplier provides traceability documentation if the application requires strict quality control standards. Check for RoHS transition status if environmental compliance is critical for the final product assembly.

Selection Notes

Select this component when a standard 1 A, 100 V rectification solution is required in a small surface-mount form factor. The 0.85 V forward voltage drop offers efficiency benefits over standard PN junction diodes in low voltage applications. Consider the 30 A surge capability for circuits experiencing transient inrush currents. The wide temperature range makes it suitable for automotive or industrial environments where thermal management is challenging.
