Overview
The Diodes Incorporated 1N5820-T is a Schottky barrier rectifier featuring a single-phase configuration in the DO-201AD package. It supports an average rectified output current of 3.0 A and a peak repetitive reverse voltage of 20 V. The device exhibits a maximum forward voltage of 0.475 V at 3.0 A and 0.850 V at 9.4 A, with a peak reverse current of 2.0 mA at rated DC blocking voltage. It withstands an 80 A non-repetitive peak forward surge current and operates within a temperature range of -65 to +125 °C.
Feature Summary
- Utilizes Schottky barrier chip technology for low power loss and high efficiency
- Incorporates guard ring die construction designed for transient protection
- Constructed with plastic material classified as UL flammability rating 94V-0
Applications
- Low voltage, high frequency inverters
- Free wheeling diode circuits
- Polarity protection applications
Procurement Notes
Verify that the specific ordering suffix corresponds to reel packaging when sourcing this component. Confirm RoHS compliance status and manufacturer lot codes against the official datasheet specifications prior to integration into production schedules.
Selection Notes
Select this component for designs requiring low forward voltage drop and high surge capability. Ensure thermal management accounts for the specified junction-to-lead thermal resistance. Verify lead length requirements for accurate current derating calculations based on ambient temperature conditions.
Part Context
This part belongs to the 1N5820-1N5822 series of 3.0A Schottky Barrier Rectifiers manufactured by Diodes Incorporated. The series shares identical mechanical dimensions and general electrical characteristics, differentiated primarily by their peak repetitive reverse voltage ratings ranging from 20 V to 40 V.
Replacement Considerations
Cross-reference with other manufacturers offering 1N5820 equivalents in the DO-201AD package. Verify that substitute parts meet the 3.0 A current rating and 20 V reverse voltage requirements while maintaining compatible forward voltage and surge current specifications.
FAQ
What is the typical total capacitance of the 1N5820-T?
The typical total capacitance is measured at 25°C junction temperature, 1 MHz frequency, and 50 mVp-p signal level.
How does the average output current change with lead temperature?
The average output current must be derated according to the forward current derating curve provided in the datasheet as the lead temperature increases above 95°C.
