EC21QS04

Single Diodes Overview

The KYOCERA AVX EC21QS04 is a surface-mount Schottky barrier rectifier housed in the DO-214AC (SMA) package. It features a maximum repetitive peak reverse voltage of 40V and an average forward rectified current rating of 2A. The device utilizes a low-profile, lead-free design compliant with RoHS standards, making it suitable for high-efficiency power conversion applications requiring fast switching characteristics.

Single Diodes Feature Summary

• Schottky barrier construction for minimal forward voltage drop
• Low-profile surface mount packaging for space-constrained designs
• Lead-free terminal finish compatible with standard reflow processes

Single Diodes Applications

• DC-DC converter output rectification
• Free-wheeling diodes in synchronous rectifier circuits
• Reverse polarity protection in low-voltage power supplies

Single Diodes Procurement Notes

Verify the specific ordering suffix to ensure the correct tape and reel configuration matches your assembly requirements. Confirm that the component meets the necessary environmental compliance standards for your target market. Cross-reference the manufacturer's latest datasheet to validate electrical parameters against your circuit design specifications before finalizing procurement.

Single Diodes Selection Notes

Select this component when a low forward voltage drop is critical for system efficiency. Ensure the operating junction temperature remains within specified limits during peak load conditions. Verify that the 40V reverse voltage rating provides adequate margin for transient spikes in the application environment.

Single Diodes Part Context

This device belongs to KYOCERA AVX's portfolio of surface-mount Schottky rectifiers designed for general-purpose power management. It complements other SMA-packaged diodes by offering a balance of current handling capability and switching speed.
