Overview
The onsemi 1N5820RL 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. Its non-repetitive peak forward surge current capability reaches 30 A for a single half-sine wave under specified conditions. The component operates within a junction temperature range of -65°C to +175°C, ensuring reliability in various thermal environments.
Feature Summary
- Low forward voltage drop for improved system efficiency
- High switching speed suitable for high-frequency applications
- Robust surge current handling capability
Applications
- DC-DC converters
- Free-wheeling diodes in inductive load circuits
- Power supply rectification
Procurement Notes
Verify the specific ordering suffix RL against official onsemi documentation to confirm tape-and-reel packaging specifications. Ensure the requested part number matches the exact electrical ratings required for your circuit design. Cross-reference the datasheet revision date to guarantee access to the most current mechanical and electrical parameters before finalizing procurement.
Selection Notes
Select this component when a 30 V reverse voltage rating and 1.0 A continuous current capacity are required. Consider its low forward voltage characteristic for minimizing power loss in low-voltage DC systems. Evaluate the thermal management requirements based on the specified junction temperature limits and derating curves provided in the official datasheet.
Part Context
This component belongs to the standard 1N58xx series of Schottky barrier rectifiers manufactured by onsemi. These devices are widely recognized for their fast recovery times and low leakage currents compared to standard silicon p-n junction diodes. The RL suffix typically indicates a specific reel quantity or packaging format used for automated assembly processes.
Replacement Considerations
Consult official cross-reference guides for verified equivalents such as other 1N5820 variants from different manufacturers. Ensure substitute parts match the 30 V PIV, 1.0 A average current, and DO-41 package dimensions. Verify that any replacement maintains the same thermal characteristics and reverse leakage specifications.
