Overview
The Lumimax Optoelectronic Technology 1N5817-T is a Schottky Barrier Rectifier housed in the DO-204AL (DO-41) axial package. It features a maximum repetitive peak reverse voltage of 20 V and supports an average forward rectified current of 1.0 A. The device exhibits a maximum instantaneous forward voltage ranging from 0.450 V to 0.750 V depending on test conditions, with a maximum DC reverse current of 1.0 mA at rated blocking voltage. It withstands a peak forward surge current of 25 A and operates within a temperature range of -55°C to +125°C.
Feature Summary
- Provides overvoltage protection capabilities
- Ensures high efficiency through low power loss
- Guarantees reliability under high temperature soldering conditions
Applications
- Overvoltage protection circuits
- Low voltage high frequency inverters
- Free wheeling applications
- Polarity protection systems
Procurement Notes
Verify that the ordering suffix '-T' corresponds to the specific tape and reel packaging configuration as defined by Lumimax Optoelectronic Technology. Confirm RoHS and REACH compliance status for the specific manufacturing batch. Ensure the component meets MIL-STD-202E Method 208C solderability requirements for lead plating before integration into production lines.
Selection Notes
Select this component when a low forward voltage drop and fast switching speed are required for high efficiency designs. The DO-41 package is suitable for through-hole mounting where high surge current capability is necessary. Verify thermal resistance constraints against the application's ambient temperature requirements to ensure operation remains within the specified junction temperature limits.
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. These devices share common mechanical characteristics and are designed for general-purpose rectification in low voltage applications requiring high efficiency.
Replacement Considerations
Compatible substitutes include the 1N5817-TP from Micro Commercial Components and the 1N5817 from Diodes Inc. Verify pinout compatibility and electrical parameter alignment before substitution.
