1N5822RL

Overview

The onsemi 1N5822RL is a Schottky barrier rectifier featuring a 40 V repetitive peak reverse voltage and a 3 A average forward current rating. It utilizes a DO-201AD axial through-hole package with two pins. Key electrical parameters include a maximum forward voltage of 950 mV at 3 A, a peak reverse leakage current of 2 mA, and a peak non-repetitive forward surge current of 80 A. The device operates within a temperature range of -65°C to 125°C and exhibits a peak reverse recovery time of 1.6 ns.

Feature Summary

• Employs Schottky barrier principle for majority carrier conduction
• Features extremely low forward voltage drop for high efficiency
• Designed for negligible switching losses due to low stored charge
• Utilizes chrome barrier metal and epitaxial construction

Applications

• Low-voltage, high-frequency inverters
• Free wheeling diodes in power circuits
• Polarity protection applications
• Switch mode power supplies

Procurement Notes

Verify the specific manufacturer datasheet for the 1N5822RL suffix to confirm exact electrical tolerances and packaging details. Ensure the component meets required thermal management standards for the intended operating environment. Cross-reference the part number with official onsemi documentation to validate availability and any potential obsolescence notices before finalizing procurement plans.

Selection Notes

Select this component for designs requiring efficient rectification in low-voltage, high-frequency environments. The DO-201AD package suits through-hole mounting requirements. Consider the 3 A current rating and 40 V voltage limit when sizing for load conditions. Evaluate thermal dissipation needs based on the specified forward voltage drop and ambient operating temperatures.

Part Context

This part belongs to the 1N5822 series of axial lead rectifiers manufactured by onsemi. The series employs large area metal-to-silicon power diodes with oxide passivation. The RL suffix typically indicates tape and reel packaging, facilitating automated assembly processes compared to bulk bag packaging options available for standard variants.

Replacement Considerations

Compatible substitutes include the 1N5822 from other manufacturers such as Rectron or STMicroelectronics, provided they meet identical 40 V, 3 A specifications and DO-201AD package dimensions. Verify pinout compatibility and thermal characteristics before substitution.
