Overview
The CDBM120L-G is a Schottky Barrier Rectifier manufactured by Comchip Technology, designed for low voltage surface mount applications. It features a MiniSMA (DO-214AC) package and provides an average rectified forward current of 1.0 Ampere with a maximum repetitive peak reverse voltage of 20 Volts. The device utilizes silicon epitaxial planar chip technology to achieve ultra-high-speed switching and low forward voltage drop characteristics.
Feature Summary
- Low profile surface mount design optimized for board space efficiency
- Ultra-high-speed switching capability with low forward voltage drop
- Guardring structure providing protection against overvoltage conditions
Applications
- Low voltage high frequency inverters
- Free wheeling diode circuits
- Polarity protection systems
Procurement Notes
Verify the specific suffix 'G' indicates RoHS compliance and halogen-free status as per manufacturer documentation. Confirm the package designation matches the required MiniSMA footprint. Ensure the 20V reverse voltage rating aligns with circuit requirements. Check for any specific ordering codes that may affect lead times or packaging quantities.
Selection Notes
Select this component for applications requiring compact SMD solutions with fast switching speeds. The 1A current rating suits moderate power levels in low voltage environments. Consider the thermal resistance and junction temperature limits when designing heat dissipation strategies for dense PCB layouts.
Part Context
This part belongs to the CDBM series of Schottky Barrier Rectifiers from Comchip Technology. The series is characterized by batch process design and excellent power dissipation capabilities. These devices are engineered to offer better reverse leakage current performance and thermal resistance compared to standard alternatives.
Replacement Considerations
Compatible substitutes include other 1A 20V Schottky diodes in MiniSMA packages such as the CDBM120-G or CDBM140L-G variants within the same manufacturer's lineup. Verify pinout compatibility and electrical parameters before substitution.
