1N5817

Overview

The Lumimax Optoelectronic Technology 1N5817 is a Schottky Barrier Rectifier housed in the DO-204AL (DO-41) axial package. It features a maximum average forward rectified current of 1.0 A and a peak forward surge current capability of 25 A. The device supports a maximum recurrent peak reverse voltage of 20 V and operates within a temperature range of -55°C to +125°C. Electrical characteristics include a maximum instantaneous forward voltage ranging from 0.450 V to 0.900 V depending on test conditions, a maximum DC reverse current of 1.0 mA at rated blocking voltage, and a typical junction capacitance of 110 pF.

Feature Summary

• Provides overvoltage protection with low forward voltage drop for high efficiency
• Features high surge current capability suitable for demanding power applications
• Guaranteed high temperature soldering performance up to 250°C for ten seconds

Applications

• Overvoltage protection circuits
• High efficiency rectification systems
• Low voltage power supply designs

Procurement Notes

Verify component authenticity by cross-referencing the manufacturer marking with the official Lumimax datasheet specifications. Confirm that the package type matches the DO-204AL standard and check for RoHS compliance documentation. Ensure the ordering details align with the specific electrical ratings required for your circuit design before finalizing procurement.

Selection Notes

Select this component when a 20 V reverse voltage rating and 1 A continuous current capacity are required. Consider the low forward voltage characteristic for minimizing conduction losses in low-voltage applications. Verify thermal management requirements against the specified junction-to-ambient thermal resistance for the intended operating environment.

Part Context

This part belongs to the 1N581x series of Schottky barrier rectifiers manufactured by Lumimax Optoelectronic Technology. The series includes variants with different reverse voltage ratings, such as the 1N5818 and 1N5819, while maintaining consistent current handling capabilities and mechanical packaging standards across the lineup.
