Overview
The Vishay General Semiconductor - Diodes Division 1N5820-E3/54 is a Schottky barrier plastic rectifier housed in the DO-201AD axial package. It features a maximum repetitive peak reverse voltage of 20 V and supports a maximum average forward rectified current of 3.0 A at a lead temperature of 95 °C. The device exhibits a maximum instantaneous forward voltage of 0.475 V at 3.0 A and handles an 80 A non-repetitive peak forward surge current. Operating junction temperatures range from -65 °C to +125 °C, with a typical thermal resistance of 40 °C/W.
Feature Summary
- Guardring structure provides overvoltage protection
- Extremely fast switching speeds for high frequency operation
- Low forward voltage drop minimizes conduction losses
- High forward surge capability ensures robust performance
Applications
- Low voltage high frequency inverters
- Freewheeling applications
- DC/DC converters
- Polarity protection circuits
Procurement Notes
Verify component authenticity by checking the manufacturer's part number against official datasheet documentation. Confirm that the E3 suffix indicates RoHS compliance and JESD 201 class 1A whisker test adherence. Ensure the ordering code matches the specified reel quantity and delivery mode before finalizing procurement orders.
Selection Notes
Select this component when a low forward voltage drop and fast switching speed are required for power conversion tasks. The 20 V reverse voltage rating suits low voltage DC/DC converter designs. Verify that the 3.0 A continuous current capacity meets the specific load requirements of the target application circuit.
Part Context
This component belongs to the 1N5820, 1N5821, and 1N5822 series of Schottky barrier plastic rectifiers manufactured by Vishay General Semiconductor. All variants share identical mechanical dimensions and electrical characteristics except for their maximum repetitive peak reverse voltage ratings, which vary across the series.
Replacement Considerations
Direct substitutes include the 1N5820G from onsemi and the 1N5820-TP from MCC (Micro Commercial Components). These alternatives offer comparable specifications for equivalent circuit integration.
FAQ
What does the E3 suffix indicate for this component?
The E3 suffix denotes that the component is RoHS-compliant and has passed the JESD 201 class 1A whisker test.
How is cathode polarity identified on the device?
A color band printed on the plastic body denotes the cathode end of the rectifier.
