Overview
The onsemi 1N5820 is a Schottky Barrier Rectifier designed for low forward voltage drop and high switching efficiency. It features a maximum average forward rectified current of 1.0 A at an ambient temperature of 75°C. The device supports a repetitive peak reverse voltage of 30 V with a maximum RMS voltage of 21 V. Reverse leakage current is specified at 10 mA maximum at 30 V DC. The component operates within a junction temperature range of -65°C to +175°C, ensuring reliability in various power supply applications.
Feature Summary
- Schottky barrier construction enables fast switching speeds and minimal reverse recovery time.
- Low forward voltage drop reduces conduction losses and improves overall system efficiency.
- High surge current capability provides robustness against transient overload conditions.
Applications
- DC-DC converters
- Free-wheeling diodes in inductive load circuits
- Power supply rectification
Procurement Notes
Verify the specific package marking and date code against the official datasheet to ensure authenticity. Confirm that the ordering suffix matches the required tape and reel or tube configuration. Check for RoHS compliance status if environmental regulations apply to your manufacturing process. Ensure storage conditions adhere to moisture sensitivity levels defined by the manufacturer.
Selection Notes
Select this component when a low forward voltage drop is critical for efficiency. Ensure the operating reverse voltage does not exceed the 30 V rating under all transient conditions. Verify thermal management requirements to maintain junction temperatures within the specified limits during continuous operation.
Part Context
This part belongs to the standard 1N58xx series of Schottky rectifiers. It shares pinout compatibility with other devices in the series but differs in voltage ratings. The 1N5820 specifically targets applications requiring moderate voltage blocking capabilities combined with high-frequency switching performance.
Replacement Considerations
Direct replacements include the 1N5821 (40V) or 1N5822 (40V) if higher voltage margins are acceptable. Other compatible parts from different manufacturers must match the 1.0A current rating and DO-41 axial package dimensions. Verify electrical parameters such as reverse leakage and forward voltage before substitution.
