Overview
The Diodes Incorporated 1N5818-B is a 1.0A Schottky Barrier Rectifier housed in the DO-41 plastic package. It features a peak repetitive reverse voltage of 30V and an average rectified output current of 1.0A at 90°C lead temperature. The device exhibits a maximum forward voltage of 0.550V at 1.0A and 0.875V at 3.0A, with a peak reverse leakage current of 1.0mA at rated DC blocking voltage. It supports non-repetitive peak forward surge currents up to 25A and operates within a junction temperature range of -65°C to +125°C.
Feature Summary
- Guard ring die construction provides transient protection capabilities
- Low power loss and high efficiency design for improved performance
- High surge and high current capability suitable for demanding loads
- Lead-free finish compliant with RoHS directives
Applications
- Low-voltage, high-frequency inverters
- Free wheeling applications
- Polarity protection circuits
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm packaging configuration and compliance status. Confirm that the component meets all applicable regulatory requirements for your intended deployment environment before finalizing procurement decisions.
Selection Notes
Select this component when a low forward voltage drop and fast switching speed are required for efficient power conversion. Ensure the circuit design accommodates the specified thermal resistance and derating factors for capacitive loads to maintain reliable operation under varying environmental conditions.
Part Context
This part belongs to the 1N581x series of Schottky barrier rectifiers manufactured by Diodes Incorporated. The series includes variants with different reverse voltage ratings, such as the 1N5817 (20V) and 1N5819 (40V), sharing identical mechanical dimensions and general electrical characteristics while differing in breakdown voltage specifications.
Replacement Considerations
Compatible substitutes include the 1N5817-T and 1N5819-T from the same manufacturer family. Verify that alternative components match the 30V reverse voltage requirement and DO-41 package constraints for direct integration.
