Overview
The Diodes Incorporated 1N5822-B is a Schottky barrier rectifier featuring a 40 V peak repetitive reverse voltage and a 3.0 A average rectified output current. It utilizes DO-201AD axial packaging with molded plastic construction rated UL 94V-0. Electrical characteristics include a maximum forward voltage of 0.525 V at 3.0 A and 0.950 V at 9.4 A, alongside a peak reverse current of 2.0 mA at 25°C rising to 20 mA at 100°C. The device supports non-repetitive peak forward surge currents of 80 A and operates within a junction temperature range of -65°C to +125°C.
Feature Summary
- Guard ring die construction provides transient protection capabilities
- Low power loss and high efficiency design suitable for low voltage applications
- High surge capability combined with high current handling performance
Applications
- Low voltage, high frequency inverters
- Free wheeling circuits
- Polarity protection systems
Procurement Notes
Verify the specific suffix designation against official manufacturer documentation to confirm exact electrical tolerances or marking variations. Confirm package dimensions and lead solderability specifications match MIL-STD-202 Method 202 requirements. Ensure thermal resistance parameters align with your printed circuit board copper pad layout and lead length constraints for accurate derating calculations.
Selection Notes
Select this component for designs requiring low forward voltage drop to minimize conduction losses in high-efficiency power paths. Evaluate the 80 A surge rating against potential inrush currents during startup conditions. Consider the 40 V reverse voltage limit when designing for AC line rectification or DC bus applications with voltage spikes.
Part Context
This part belongs to the 1N582x series of Schottky barrier rectifiers manufactured by Diodes Incorporated. The series covers voltage ratings from 20 V to 40 V while maintaining a consistent 3.0 A current capacity. These devices are engineered for general-purpose rectification where speed and efficiency are prioritized over high voltage blocking capabilities.
Replacement Considerations
Cross-reference with other manufacturers offering DO-201AD packaged Schottky diodes rated for 40 V and 3 A. Verify that substitute parts meet the same forward voltage and reverse leakage current specifications to ensure circuit compatibility.
