SR320

Single Diodes Overview

The SR320 is a Schottky barrier rectifier diode manufactured by Taiwan Semiconductor Corporation. It features a single-element silicon construction housed in the DO-201AD plastic package. The device is rated for a maximum repetitive reverse voltage of 200V and an average forward rectified current of 3A. Key electrical parameters include a maximum non-repetitive peak forward surge current of 80A, a maximum forward voltage drop of 0.95V, and a maximum operating junction temperature of 150°C. The component complies with RoHS directives and is halogen-free.

Single Diodes Feature Summary

• Low forward voltage drop for high efficiency
• Guardring structure for overvoltage protection
• High surge current capability
• Free wheeling diode design with low power loss

Single Diodes Applications

• Efficiency-oriented freewheeling applications
• General purpose rectification in power supplies
• DC-DC converter output stages

Single Diodes Procurement Notes

Verify the specific ordering suffix to confirm packaging variations such as halogen-free or AEC-Q101 qualification status. Ensure the DO-201AD package type matches the target PCB footprint. Confirm RoHS compliance documentation aligns with regional regulatory requirements before finalizing procurement orders.

Single Diodes Selection Notes

Select this component when a 200V reverse voltage rating and 3A continuous current capacity are required. The Schottky technology offers lower forward voltage compared to standard PN junctions, reducing conduction losses. Verify thermal management capabilities for the 150°C maximum junction temperature limit in the intended application environment.

Single Diodes Part Context

The SR320 belongs to the SR302 through SR320 series of Schottky Barrier Rectifiers from Taiwan Semiconductor. This family utilizes guardring technology for enhanced reliability. The devices are designed for general-purpose switching applications requiring fast recovery characteristics and low power dissipation in compact axial leaded packages.

Single Diodes Replacement Considerations

Cross-reference with other manufacturers' DO-201AD Schottky diodes rated at 3A and 200V. Verify that substitute parts meet the same forward voltage and surge current specifications to ensure circuit performance parity.
