Overview
The Vishay 1N5820-E3/73 is a Schottky barrier rectifier in the DO-201AD axial package. It features a maximum repetitive peak reverse voltage of 20 V and supports an average forward rectified current of 3.0 A at 95 °C lead temperature. 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 for high frequency operation
- Low forward voltage drop minimizes conduction losses
- High forward surge capability
Applications
- Low voltage high frequency inverters
- Freewheeling applications
- DC/DC converters
- Polarity protection circuits
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm packaging details. The /73 designation indicates ammo pack packaging with a base quantity of 1000 units. Confirm RoHS compliance status and material categorization requirements prior to procurement to ensure alignment with project specifications.
Selection Notes
Select this component when a low forward voltage drop and fast switching speed are required for 20 V DC blocking applications. Ensure the design accommodates the 3.0 A average forward current rating and the specified thermal resistance characteristics. Verify that the operating environment remains within the -65 °C to +125 °C junction temperature limits.
Part Context
This part belongs to the Vishay 1N5820, 1N5821, and 1N5822 series of Schottky barrier plastic rectifiers. All variants share identical mechanical construction and electrical characteristics except for their maximum repetitive peak reverse voltage ratings. The E3 suffix denotes RoHS compliance and matte tin-plated leads.
Replacement Considerations
Direct substitutes include the 1N5820G manufactured by onsemi and the 1N5820-TP manufactured by MCC (Micro Commercial Components). Verify pinout compatibility and thermal performance before implementation.
FAQ
What does the color band on the component indicate?
The color band denotes the cathode end of the diode.
Is the component compliant with RoHS standards?
Yes, the Base P/N-E3 is RoHS-compliant and commercial grade.
