Overview
The Vishay General Semiconductor 1N5817/54 is a Schottky barrier rectifier in the DO-204AL (DO-41) package. It features a maximum repetitive peak reverse voltage of 20 V and a maximum 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 a typical junction capacitance of 125 pF at 4.0 V and 1.0 MHz. Operating temperatures range from -65 to +125 °C, with a peak forward surge current rating of 25 A.
Feature Summary
- Guardring structure provides overvoltage protection
- Extremely fast switching for high frequency operation
- Low forward voltage drop minimizes conduction losses
Applications
- Low voltage high frequency inverters
- Freewheeling applications
- DC-to-DC converters
- Polarity protection circuits
Procurement Notes
Verify that the ordering suffix /54 corresponds to the specific bulk packaging configuration required for your assembly process. Confirm RoHS compliance status as indicated by the base part number designation. Ensure the component meets the thermal resistance requirements for your specific PCB mounting orientation and copper pad dimensions.
Selection Notes
Select this component when a low forward voltage drop and fast switching speed are critical for efficiency in low voltage power conversion. The 20 V reverse voltage rating suits applications requiring moderate blocking capabilities. Verify that the 1.0 A continuous current rating aligns with the expected load conditions and ambient temperature derating curves provided in the datasheet.
Part Context
This part belongs to the 1N5817 through 1N5819 series of Schottky Barrier Rectifiers manufactured by Vishay General Semiconductor. The series shares identical mechanical construction and electrical characteristics except for the maximum repetitive peak reverse voltage ratings, which vary across the family members.
Replacement Considerations
Direct substitutes within the same Vishay series include the 1N5818 and 1N5819, which offer higher reverse voltage ratings of 30 V and 40 V respectively while maintaining the same current and package specifications.
