Overview
The CDBA340-G is a surface-mount Schottky barrier rectifier manufactured by Comchip Technology. It features a maximum repetitive peak reverse voltage of 40 V and an average forward current rating of 3.0 A. The device exhibits a maximum instantaneous forward voltage of 0.50 V at 3.0 A and a maximum DC reverse current of 10 mA at rated blocking voltage. It supports a peak surge forward current of 80 A under JEDEC testing conditions. The component operates within a junction temperature range of -55 °C to +150 °C and utilizes a DO-214AC (SMA) molded plastic package.
Feature Summary
- Low forward voltage drop for improved efficiency
- Majority carrier conduction with ultra-fast switching
- Built-in strain relief in the plastic package
- Halogen-free construction compliant with environmental standards
Applications
- Low voltage high frequency inverters
- Free wheeling diode circuits
- Polarity protection applications
Procurement Notes
Verify the specific part number against the manufacturer's official datasheet to confirm electrical ratings and package dimensions. Ensure compliance with RoHS and halogen-free requirements if mandated by your design specifications. Confirm that the ordering suffix matches the desired performance characteristics, as variations exist within the product family.
Selection Notes
Select this component for designs requiring a 40 V reverse voltage rating and 3.0 A continuous current capability in a compact SMA footprint. Consider the thermal resistance values when determining heat dissipation requirements on the PCB. Evaluate the forward voltage drop against system efficiency targets compared to standard silicon rectifiers.
Part Context
This device belongs to the CDBA series of SMD Schottky Barrier Rectifiers from Comchip Technology. The series covers reverse voltages from 20 V to 100 V with a consistent 3.0 A forward current rating. These components are designed for surface mount applications, offering reliability through UL 94V-0 flammability classification and standardized JEDEC packaging.
Replacement Considerations
Compatible substitutes include CDBA340L-HF and CDBA340LR-HF from Comchip Technology. Verify pinout compatibility and ensure equivalent or superior electrical parameters before substitution.
