Overview
The 1N5819-E3/54 is a Schottky Barrier Plastic Rectifier manufactured by Vishay General Semiconductor. It features a single diode configuration in a DO-204AL (DO-41) through-hole package. Key electrical parameters include a maximum repetitive peak reverse voltage of 40 V, a maximum average forward rectified current of 1.0 A, and a peak forward surge current of 25 A. The device exhibits a maximum instantaneous forward voltage of 0.600 V at 1.0 A and a typical junction capacitance of 110 pF. Operating temperatures range from -65 °C to +125 °C.
Feature Summary
- Guardring structure provides overvoltage protection
- Extremely fast switching with very small conduction losses
- Matte tin plated leads are solderable per J-STD-002 and JESD 22-B102
- E3 suffix meets JESD 201 class 1A whisker test
Applications
- Low voltage high frequency inverters
- Freewheeling applications
- DC/DC converters
- Polarity protection applications
Procurement Notes
Verify the specific ordering suffix /54 corresponds to the 13-inch diameter paper tape and reel packaging with a base quantity of 5500 units. Confirm RoHS compliance status via official documentation as the E3 suffix indicates commercial grade compliance. Ensure lead length requirements match the thermal resistance ratings provided for vertical PCB mounting.
Selection Notes
Select this component for circuits requiring low forward voltage drop and high-frequency operation. The 40 V rating suits low-voltage power supplies. Verify that the 1.0 A continuous current rating meets load requirements. Consider the DO-41 package dimensions for board layout. Validate thermal performance against derating curves for expected case temperatures.
Part Context
This part belongs to the 1N5817, 1N5818, and 1N5819 series of Schottky Barrier Plastic Rectifiers. All variants share identical physical packages and thermal characteristics but differ in reverse voltage ratings. The 1N5819 specifically offers the highest voltage rating within this three-part family at 40 V.
Replacement Considerations
Direct substitutes within the same Vishay series include 1N5817 and 1N5818, though their lower reverse voltage ratings must be validated against circuit requirements.
