Overview
The STMicroelectronics 1N5820RL is an axial power Schottky rectifier housed in a DO-201AD package. It features a repetitive peak reverse voltage of 20 V and an average forward current rating of 3 A at a case temperature of 100°C. The device exhibits a maximum forward voltage drop of 0.475 V at 3 A and supports a non-repetitive surge current of 80 A. Designed for low-voltage, high-frequency applications, it offers negligible switching losses and specified avalanche capability.
Feature Summary
- Extremely fast switching with negligible switching losses
- Low forward voltage drop for reduced conduction losses
- Specified avalanche capability for robust operation
Applications
- Switch Mode Power Supplies
- High frequency DC to DC converters
- Free wheeling diodes
- Polarity protection circuits
- Small battery chargers
Procurement Notes
Verify the specific ordering suffix RL indicates tape and reel packaging containing 1900 units per base quantity. Confirm the component meets UL94 V0 flammability standards for the epoxy material. Ensure the selected variant matches the required 20 V reverse voltage rating for the target circuit design.
Selection Notes
Select this component for low-voltage, high-frequency rectification where minimal conduction loss is critical. The 20 V rating suits applications requiring polarity protection or free-wheeling paths. Consider thermal resistance values when designing heatsinking solutions for continuous operation above ambient temperatures.
Part Context
This part belongs to the 1N582x series of low drop power Schottky rectifiers manufactured by STMicroelectronics. The series includes variants with different reverse voltage ratings, such as 30 V and 40 V options, all sharing similar axial DO-201AD packaging and performance characteristics optimized for efficiency.
Replacement Considerations
Compatible substitutes include other 1N5820 equivalents from manufacturers like onsemi or JGD. Verify that replacement parts maintain the same DO-201AD footprint, 20 V reverse voltage, and 3 A current handling capabilities.
