Overview
The Vishay 1N5817-E3/53 is a Schottky Barrier Plastic Rectifier in the DO-41 (DO-204AL) axial package. It features a maximum repetitive peak reverse voltage of 20 V and an average forward rectified current of 1.0 A at 90 °C lead temperature. The device exhibits a maximum instantaneous forward voltage of 0.450 V at 1.0 A and supports a peak forward surge current of 25 A. Operating junction and storage temperatures range from -65 to +125 °C, with a typical thermal resistance of 50 °C/W.
Feature Summary
- Guardring structure provides overvoltage protection
- Extremely fast switching with negligible switching losses
- Low forward voltage drop for small conduction losses
- Suitable for high frequency operation
Applications
- Low voltage high frequency inverters
- Freewheeling applications
- DC/DC converters
- Polarity protection circuits
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to confirm packaging details. The /53 designation indicates Ammo pack packaging with a base quantity of 3000 units. Confirm RoHS compliance and terminal plating specifications directly with the supplier or datasheet before procurement.
Selection Notes
Select this component for low voltage, high frequency rectification where minimal conduction loss is critical. Ensure the circuit operates within the 20 V reverse voltage limit and 1.0 A average current rating. Verify thermal management requirements against the specified junction temperature limits and thermal resistance values.
Part Context
This part belongs to the Vishay 1N5817, 1N5818, and 1N5819 series of Schottky Barrier Plastic Rectifiers. These devices are designed for use in power supplies and converters requiring fast recovery and low forward voltage characteristics in standard through-hole packages.
Replacement Considerations
Cross-reference with Vishay 1N5817-E3/54 for Reel packaging or 1N5817-E3/73 for Cut Tape delivery. Other manufacturers' 1N5817 equivalents may vary in forward voltage and leakage current specifications.
