Overview
The CDBA140SL-G is a low forward voltage surface-mount Schottky barrier rectifier manufactured by Comchip Technology. It features a maximum repetitive peak reverse voltage of 40 V and a maximum average forward current of 1.0 A. The device utilizes a JEDEC DO-214AC (SMA) molded plastic case with solderable terminals compliant to MIL-STD-750 method 2026. Key electrical characteristics include a maximum DC blocking voltage of 40 V, a peak surge forward current of 35 A under standard conditions, and a maximum thermal resistance from junction to ambient of 88 °C/W. The component supports an operating junction temperature range up to 125 °C.
Feature Summary
- Super low forward voltage drop for enhanced efficiency
- JEDEC DO-214AC package with built-in strain relief
- Plastic encapsulant meets UL 94V-0 flammability classification
- Designed for easy pick-and-place surface mount assembly
Applications
- Surface mount applications requiring compact footprints
- Low voltage high frequency inverters
- Free wheeling diode circuits
- Polarity protection systems
Procurement Notes
Verify the specific suffix 'SL' against the manufacturer's official documentation to confirm exact electrical tolerances and binning specifications. Ensure the ordering part number matches the required reverse voltage and current ratings for the target circuit design. Confirm RoHS compliance status through the latest datasheet revision before finalizing procurement orders.
Selection Notes
Select this component for designs prioritizing minimal power loss in low-voltage environments. The DO-214AC package offers space optimization compared to larger through-hole alternatives. Evaluate the thermal resistance parameters relative to the PCB copper pad area to ensure adequate heat dissipation during continuous operation at rated currents.
Part Context
This device belongs to the CDBA series of Low VF SMD Schottky Barrier Rectifiers produced by Comchip Technology. The series encompasses variants ranging from 20 V to 40 V reverse voltage capabilities. All models share common mechanical attributes including the SMA footprint and similar thermal management profiles, differing primarily in their voltage blocking specifications.
Replacement Considerations
Compatible substitutes within the same series include CDBA120L-G, CDBA140L-G, and CDBA140LL-G. Verify that alternative part numbers meet the specific 40 V reverse voltage requirement and 1.0 A forward current capacity necessary for the application.
