Overview
The STMicroelectronics 1N5818RL is a low drop power Schottky rectifier packaged in DO-41. It features an average forward current of 1 A and a repetitive peak reverse voltage of 30 V. The maximum forward voltage drop is 0.50 V at 1 A, with a maximum reverse leakage current of 0.5 mA at 25 °C. The device supports a maximum operating junction temperature of 150 °C and includes specified avalanche capability.
Feature Summary
- Extremely fast switching with negligible switching losses
- Very small conduction losses due to low forward voltage drop
- Specified avalanche capability for robust operation
Applications
- Switch Mode Power Supplies
- High frequency DC to DC converters
- Low voltage high frequency inverters
- Free wheeling circuits
- Polarity protection
- Small battery chargers
Procurement Notes
Verify the 'RL' suffix indicates tape and reel packaging containing 5000 units per base quantity. Confirm the specific part number matches the required electrical ratings and package dimensions before procurement. Ensure compliance with environmental standards such as ECOPACK specifications if applicable to the project requirements.
Selection Notes
Select this component for applications requiring low forward voltage drop and fast switching speeds. The DO-41 axial package suits through-hole designs. Consider the 30 V reverse voltage rating and 1 A average current limits when designing the circuit to ensure safe operating conditions within the specified thermal resistance parameters.
Part Context
This component belongs to the 1N581x series of low drop power Schottky rectifiers manufactured by STMicroelectronics. The series includes variants with different reverse voltage ratings, specifically the 1N5817 (20 V), 1N5818 (30 V), and 1N5819 (40 V). All share similar physical characteristics and performance profiles suited for general-purpose rectification.
Replacement Considerations
Compatible substitutes include the 1N5817 and 1N5819 from the same manufacturer family. Verify that alternative parts match the 30 V reverse voltage requirement and DO-41 package form factor to ensure direct interchangeability in existing designs.
