Overview
The Diodes Incorporated 1N5821-B is a Schottky barrier rectifier featuring a guard ring die construction for transient protection. It operates within a -65°C to +125°C temperature range and utilizes a DO-201AD package. Key electrical parameters include a maximum repetitive peak reverse voltage of 30 V, an average rectified output current of 3.0 A at a lead temperature of 95°C, and a non-repetitive peak forward surge current of 80 A. The device exhibits a typical thermal resistance from junction to ambient of 40°C/W.
Feature Summary
- Guard ring die construction provides enhanced transient protection capabilities
- Low forward voltage drop ensures high efficiency and reduced power loss
- High surge capability supports demanding load conditions
Applications
- Low voltage, high frequency inverters
- Free wheeling circuits
- Polarity protection applications
Procurement Notes
Verify the specific suffix designation against official manufacturer documentation to confirm exact ordering specifications. Ensure compatibility with required flammability ratings and terminal solderability standards before procurement. Confirm that the component meets all necessary regulatory compliance requirements for the intended deployment environment.
Selection Notes
Select this component for applications requiring robust transient protection and high efficiency in low voltage environments. Evaluate thermal management needs based on the specified thermal resistance values. Consider the operating temperature range and current derating curves to ensure reliable performance under varying load conditions.
Part Context
This component belongs to the 1N5820-1N5822 series of 3.0A Schottky barrier rectifiers manufactured by Diodes Incorporated. The series shares common mechanical data and general features, differentiated primarily by their voltage ratings. The 1N5821 variant specifically targets applications requiring a 30V blocking voltage threshold.
Replacement Considerations
Compatible substitutes within the same series include the 1N5820 and 1N5822, provided their respective voltage ratings align with circuit requirements. Verify that alternative components match the DO-201AD package dimensions and electrical characteristics.
