Overview
The 1N5819-T is a Schottky Barrier Rectifier manufactured by Lumimax Optoelectronic Technology, 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. The device exhibits a maximum instantaneous forward voltage ranging from 0.600 V to 0.900 V at specified currents and a maximum DC reverse current of 10 mA at rated blocking voltage. It withstands a peak forward surge current of 25 A and operates within a junction temperature range of -55 °C to +125 °C.
Feature Summary
- Provides overvoltage protection through high surge current capability
- Ensures low power loss and high efficiency via low forward voltage characteristics
- Guarantees reliability with high temperature soldering tolerance up to 250°C for 10 seconds
Applications
- Overvoltage protection circuits
- Low voltage high frequency inverters
- Free wheeling diodes
- Polarity protection applications
Procurement Notes
Verify that the component matches the specific 1N5819 variant with a 40V rating, distinct from the 1N5817 or 1N5818 models which have lower voltage ratings. Confirm the package is DO-204AL (DO-41) axial leaded type. Ensure compliance with RoHS and REACH standards if required by your assembly specifications. Check datasheet revisions for any updates to thermal resistance or electrical limits.
Selection Notes
Select this component when a 40V reverse voltage rating and 1A continuous current capacity are required. It is suitable for applications demanding low forward voltage drop to minimize conduction losses. Consider the DO-41 package size for through-hole mounting constraints. Evaluate the thermal resistance of 50 °C/W against your ambient temperature conditions to ensure the junction temperature remains within the +125 °C limit during operation.
Part Context
This part belongs to the 1N5817 ~ 1N5819 series of Schottky Barrier Rectifiers produced by Lumimax Optoelectronic Technology. The series shares common mechanical data and electrical characteristics such as average forward current and surge capability, differentiated primarily by their maximum repetitive peak reverse voltage ratings of 20V, 30V, and 40V respectively.
Replacement Considerations
Compatible substitutes include other manufacturers' 1N5819 devices in the DO-41 package, such as those from Diodes Incorporated or STMicroelectronics, provided they meet the 40V reverse voltage and 1A forward current specifications.
