Overview
The CDBMS1100-HF is a silicon epitaxial planar Schottky barrier rectifier manufactured by Comchip Technology. It features a single diode configuration in an SOD-123F-2 surface-mount package. Key electrical parameters include a repetitive reverse voltage (Vrrm) of 100 V, a forward current (If) of 1 A, and a maximum forward voltage drop (Vf) of 0.85 V at rated current. The device supports a forward surge current (Ifsm) of 30 A and exhibits a reverse leakage current (Ir) of 0.5 mA. It operates within a junction temperature range of -55°C to +150°C.
Feature Summary
- Ultra-high-speed switching capability for high-frequency applications
- Low profile package design offering improved thermal resistance
- Guarding functionality for overvoltage protection scenarios
Applications
- High-frequency rectification in power supply circuits
- Free-wheeling diodes in DC-DC converters
- Overvoltage protection stages in electronic systems
Procurement Notes
Verify the specific suffix 'HF' against the manufacturer's latest documentation to confirm lead-free compliance status. Ensure the ordering part number matches the required package variant, as Comchip utilizes similar prefixes for different series such as CDBMT or ACDB. Cross-reference the datasheet revision date to validate operating temperature ranges and electrical limits before finalizing procurement specifications.
Selection Notes
Select this component when a 100 V blocking voltage and 1 A continuous current rating are required in a compact SMD form factor. The low forward voltage drop makes it suitable for efficiency-critical designs. Compare thermal performance against standard SOD-123 packages if space constraints allow, noting the specific thermal resistance characteristics defined in the official datasheet for the SOD-123F-2 footprint.
Part Context
This device belongs to Comchip Technology's Schottky Barrier Diode portfolio, specifically designed for surface-mount assembly. It shares functional similarities with other 1A/100V variants in the lineup but is distinguished by its specific low-profile packaging and silicon epitaxial planar construction. The product line emphasizes high efficiency and rapid switching speeds for modern power management applications.
Replacement Considerations
Publicly confirmed direct substitute part numbers are not available in the provided source material. Engineers should consult the manufacturer's official substitution guide or equivalent parameter matching services to identify compatible alternatives from Comchip or other vendors.
