Overview
The Comchip Technology CDBM220-G is a surface-mount Schottky barrier rectifier designed for high-efficiency power conversion. It features a 20 V repetitive peak reverse voltage and a 2.0 A continuous forward current rating. The device utilizes a Mini-SMA (SOD-123) package, enabling automated pick-and-place assembly. Key electrical characteristics include a maximum forward voltage of 0.70 V at rated current and low reverse leakage current. It operates within a junction temperature range of -55°C to +125°C and supports storage temperatures from -65°C to +175°C.
Feature Summary
- Plastic package meets UL flammability classification 94V-0
- Exceeds environmental standard MIL-S-19500/228
- Terminals are solderable per MIL-STD-750 method 2026
Applications
- Surface mount applications requiring easy pick-and-place assembly
- High frequency switching circuits
- Power supply rectification
Procurement Notes
Verify the specific part number against official manufacturer documentation to confirm electrical ratings and package dimensions. Ensure compliance with RoHS directives as indicated in the datasheet. Confirm that the ordering suffix matches the required specifications before procurement.
Selection Notes
Select this component for designs requiring a compact SMD Schottky rectifier with a 20 V reverse voltage rating. The Mini-SMA package is suitable for space-constrained PCB layouts. Consider the thermal resistance and derating curves when determining heat dissipation requirements for the application environment.
Part Context
This component belongs to the CDBM series of SMD Schottky Barrier Rectifiers manufactured by Comchip Technology. The series covers various voltage ratings from 20 V to 100 V, all sharing the same Mini-SMA/SOD-123 package form factor. The 'G' suffix typically denotes RoHS compliance.
Replacement Considerations
Compatible substitutes include other SMD Schottky diodes in the SOD-123 package with equal or higher voltage and current ratings, such as the BAV99 or SS14, provided pinout and thermal characteristics match.
