Overview
The CDBA120-G is a surface-mount Schottky barrier rectifier manufactured by Comchip Technology. It features a maximum repetitive peak reverse voltage of 20 V and a maximum DC blocking voltage of 20 V. The device supports a maximum RMS voltage of 14 V and an average forward rectified current of 1.0 A. Peak forward surge current is rated at 40 A under JEDEC testing conditions. Maximum instantaneous forward voltage is 0.75 V at 1.0 A, while maximum reverse current is limited to 10 mA at rated DC blocking voltage. Thermal resistance from junction to ambient is 80 °C/W. Operating and storage temperature ranges span from -65 °C to +150 °C.
Feature Summary
- Plastic package with Underwriters Lab flammability classification 94V-0.
- Built-in strain relief for mechanical stability.
- Terminals are solderable per MIL-STD-750 method 2026.
Applications
- Surface mount applications requiring pick and place assembly.
- Low forward voltage drop circuits.
- General purpose rectification in electronic systems.
Procurement Notes
Verify the component marking code B120 against the datasheet to confirm authenticity. Ensure the package type matches DO-214AC (SMA) specifications. Confirm RoHS compliance status through official manufacturer documentation before integration into production lines.
Selection Notes
Select this component for designs requiring a 20 V reverse voltage rating and 1.0 A continuous forward current capability. Consider the thermal resistance of 80 °C/W when designing heat dissipation strategies. Verify that the operating temperature range of -65 °C to +150 °C meets environmental requirements.
Part Context
This part belongs to the CDBA series of SMD Schottky Barrier Rectifiers produced by Comchip Technology. The series covers reverse voltages from 20 to 100 Volts with a consistent 1.0 Amp forward current rating. The CDBA120-G specifically addresses low-voltage applications within this lineup.
Replacement Considerations
Compatible substitutes include other SMA packaged Schottky diodes with matching 20 V reverse voltage and 1.0 A forward current ratings. Verify pinout compatibility and thermal characteristics before substitution.
