Overview
The CDBA120L-G is a surface mount Schottky barrier rectifier manufactured by Comchip Technology. It features a DO-214AC (SMA) molded plastic package with two terminals. The device has a maximum repetitive peak reverse voltage of 20 V and a maximum DC blocking voltage of 20 V. It supports a maximum average forward current of 1.0 A and a peak surge forward current of 35 A. The maximum instantaneous forward voltage is 0.38 V at 1.0 A. Maximum DC reverse current is 40 mA at 25°C and 88 mA at 80°C. Thermal resistance from junction to ambient is 20°C/W, and from junction to lead is 40°C/W. The operating junction temperature range is -55°C to +125°C.
Feature Summary
- Super low forward voltage drop for improved efficiency.
- Ideal for surface mount applications with easy pick and place capability.
- Plastic package meets Underwriters Lab flammability classification 94V-0.
- Built-in strain relief for mechanical stability.
Applications
- Surface mount rectification in electronic circuits.
- Low voltage high frequency inverters.

Procurement Notes
Verify the component matches the specific DO-214AC package dimensions and electrical ratings required for the design. Confirm compliance with RoHS directives as indicated in the datasheet. Ensure thermal management strategies account for the specified junction-to-ambient thermal resistance values under actual operating conditions.
Selection Notes
Select this component for applications requiring low forward voltage drop and compact surface mount packaging. Consider the 1.0 A continuous current rating and 20 V reverse voltage limits. Evaluate thermal performance based on the 20°C/W junction-to-ambient resistance. Compare against other series in the CDBA family if higher voltage or current ratings are needed.
Part Context
The CDBA120L-G belongs to the Low VF SMD Schottky Barrier Rectifiers series from Comchip Technology. This series includes variants with different reverse voltage ratings such as CDBA140SL-G. These devices are designed for general purpose rectification in surface mount technology environments, offering reliability and ease of integration into automated assembly lines.
Replacement Considerations
Compatible substitutes within the same product line include CDBA120LL-G, CDBA140L-G, CDBA140LL-G, and CDBA140SL-G. Verify that alternative part numbers match the required voltage and current specifications before implementation.
FAQ
What is the maximum non-repetitive peak forward surge current?
The maximum non-repetitive peak forward surge current is 35 A, measured using the JEDEC method for an 8.3 ms single half sine-wave superimposed on a rated load.
How does the forward voltage vary with temperature?
The forward voltage characteristics are provided in the datasheet curves, showing variation at junction temperatures of 25°C and 75°C. Specific values depend on the forward current level.
