CDBA5819-G

Overview

The CDBA5819-G is a Schottky barrier rectifier manufactured by Comchip Technology. It features a maximum repetitive peak reverse voltage of 40V and an average forward rectified current of 1A. The device utilizes silicon epitaxial planar chip technology with a metal-silicon junction. It is housed in the DO-214AC (SMA) surface-mount package, which provides a low-profile form factor suitable for high-speed mounting processes.

Feature Summary

• Low power loss and high efficiency operation
• High surge current capability
• Guardring structure for overvoltage protection
• Ultra-high-speed switching performance

Applications

• General purpose rectification
• Polarity protection circuits
• Free wheeling diode applications

Procurement Notes

Verify the specific suffix against official Comchip documentation to confirm electrical ratings and package type. Ensure compliance with RoHS and halogen-free requirements if specified for the project. Confirm lead solderability standards and polarity band orientation during integration.

Selection Notes

Select this component for applications requiring low forward voltage drop and fast recovery characteristics. The SMA package is suitable for space-constrained designs. Evaluate thermal management needs based on the 1A continuous current rating and ambient operating conditions.

Part Context

This part belongs to Comchip's SMD Schottky Barrier Rectifier series. The manufacturer specializes in discrete semiconductors with patented flat chip packaging capabilities. The product line emphasizes low profile designs and zero tin-whisker potential through gold termination technologies where applicable.

Replacement Considerations

Cross-reference with other 1A 40V Schottky diodes in the DO-214AC package. Verify pinout compatibility and thermal resistance values before substitution.
