Overview
The Vishay General Semiconductor 1N5819/54 is a Schottky Barrier Rectifier in the DO-204AL (DO-41) axial package. It features a maximum repetitive peak reverse voltage of 40 V and an average forward rectified current rating of 1.0 A at 90 °C lead temperature. The device exhibits a maximum instantaneous forward voltage of 0.600 V at 1.0 A and a typical junction capacitance of 110 pF at 4.0 V and 1.0 MHz. Operating junction temperatures range from -65 to +125 °C, with a peak forward surge current capability of 25 A.
Feature Summary
- Guardring structure provides overvoltage protection
- Extremely fast switching with negligible switching losses
- Low forward voltage drop for small conduction losses
- High frequency operation suitability
Applications
- Low voltage high frequency inverters
- Freewheeling applications
- DC-to-DC converters
- Polarity protection circuits
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm packaging details and compliance status. Confirm that the component meets RoHS directive requirements if applicable to your design specifications. Ensure thermal management aligns with the specified operating junction temperature range during implementation.
Selection Notes
Select this component for designs requiring low forward voltage drop and fast switching characteristics in power supply applications. Consider the 40 V reverse voltage rating and 1 A current capacity when matching circuit requirements. Verify compatibility with high-frequency operation needs and ensure adequate heat dissipation for the axial package.
Part Context
This part belongs to the 1N5817 through 1N5819 series of Schottky Barrier Plastic Rectifiers manufactured by Vishay General Semiconductor. These devices share similar mechanical data and feature sets, differentiated primarily by their maximum repetitive peak reverse voltage ratings ranging from 20 V to 40 V within the same DO-204AL package family.
Replacement Considerations
Cross-reference with other manufacturers offering equivalent 40 V, 1 A Schottky rectifiers in the DO-204AL package. Verify electrical parameters such as forward voltage and reverse leakage current match original specifications before substitution.
