Overview
The Lumimax Optoelectronic Technology 1N5819 is a Schottky Barrier Rectifier housed in the DO-204AL (DO-41) axial package. It features a maximum repetitive peak reverse voltage of 40 V and supports an average forward rectified current of 1.0 A with a peak forward surge current capability of 25 A. The device exhibits a maximum instantaneous forward voltage ranging from 0.600 V to 0.900 V and a maximum DC reverse current of 10 mA at rated blocking voltage. Typical junction capacitance is 110 pF, and typical thermal resistance is 50 °C/W. Operating and storage temperatures range from -55°C to +125°C.
Feature Summary
- Provides overvoltage protection capabilities
- Ensures high temperature soldering stability up to 250°C for 10 seconds
- Complies with RoHS and REACH environmental standards
Applications
- Overvoltage protection circuits
- Low power loss rectification applications
- High efficiency power conversion systems
Procurement Notes
Verify the specific manufacturer designation when sourcing this component, as the 1N5819 part number is utilized by multiple semiconductor producers including onsemi, STMicroelectronics, Vishay, and Diotec. Confirm that the supplier provides documentation matching the Lumimax Optoelectronic Technology datasheet specifications. Ensure the received components match the DO-204AL package dimensions and lead plating requirements specified in the official product data.
Selection Notes
Select this component for applications requiring a 40 V reverse voltage rating and 1 A continuous current handling. The low forward voltage drop contributes to reduced conduction losses compared to standard silicon diodes. Verify compatibility with high-frequency switching environments due to the fast switching characteristics inherent to Schottky barrier technology. Ensure the operating environment remains within the specified -55°C to +125°C temperature range.
Part Context
This component belongs to the 1N5817 through 1N5819 series of axial power Schottky rectifiers. The series shares identical physical packaging and current ratings, differing primarily in their maximum repetitive peak reverse voltage ratings. The 1N5819 represents the highest voltage variant within this specific three-part family configuration.
Replacement Considerations
Cross-reference with other manufacturers' 1N5819 parts such as those from onsemi or STMicroelectronics. Verify that substitute components meet the same 40 V reverse voltage and 1 A forward current specifications.
