Overview
The onsemi 1N5820RLG is a Schottky barrier rectifier featuring a 40 V reverse voltage rating and 3 A average forward current capability. Housed in the DO-201AD axial lead package, it utilizes chrome barrier metal and epitaxial construction for low power loss. Key electrical parameters include a maximum forward voltage of 950 mV at 3 A, a peak non-repetitive forward surge current of 80 A, and a reverse leakage current of 2 mA. The device operates within a junction temperature range of -65°C to 125°C.
Feature Summary
- Employs Schottky Barrier principle with chrome barrier metal and epitaxial construction
- Features extremely fast switching characteristics suitable for high-frequency applications
- Provides high forward surge current capability for robust circuit protection
Applications
- Low-voltage, high-frequency inverters
- Free wheeling diodes in DC-DC converters
- Polarity protection circuits
Procurement Notes
Verify the specific suffix 'RLG' confirms tape and reel packaging rather than bulk bag shipping. Confirm RoHS compliance status as required by project specifications. Ensure the component matches the DO-201AD mechanical outline dimensions for PCB footprint compatibility. Validate that the manufacturer part number corresponds exactly to the requested onsemi product line.
Selection Notes
Select this component when low forward voltage drop and high efficiency are critical for thermal management. The axial lead package facilitates through-hole mounting for applications requiring mechanical stability. Consider the 3 A current rating against peak load requirements to ensure adequate margin. Evaluate the 40 V reverse voltage rating against maximum circuit transient voltages.
Part Context
This component belongs to the 1N5822 series of Schottky barrier rectifiers from onsemi. It shares the same physical package and general performance profile as other variants in the family, differentiated primarily by reverse voltage ratings. The RL suffix indicates availability in tape and reel format for automated assembly processes.
Replacement Considerations
Cross-reference with 1N5820G for identical electrical specifications in bulk packaging. Verify pinout compatibility with existing designs before substituting with equivalent parts from other manufacturers such as Vishay or Diodes Inc.
