Overview
The 1N5819-E3/73 is a Schottky Barrier Plastic Rectifier manufactured by Vishay General Semiconductor - Diodes Division. It features a DO-41 (DO-204AL) axial package and operates with a maximum repetitive peak reverse voltage of 40 V and a maximum average forward rectified current of 1.0 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 at 4.0 V and 1.0 MHz. It supports a peak forward surge current of 25 A and functions within an operating junction temperature range of -65 to +125 °C.
Feature Summary
- Guardring structure provides overvoltage protection
- Extremely fast switching characteristics with negligible switching losses
- Low forward voltage drop for very small conduction losses
- Suitable for high frequency operation
Applications
- Low voltage high frequency inverters
- Freewheeling applications
- DC/DC converters
- Polarity protection applications
Procurement Notes
Verify the specific ordering suffix /73 corresponds to the required ammo pack packaging configuration, as other suffixes indicate different delivery modes such as paper tape and reel. Confirm RoHS compliance status via official documentation, noting that the E3 suffix indicates RoHS-compliant commercial grade material. Ensure technical parameters align with application requirements before procurement.
Selection Notes
Select this component for circuits requiring low forward voltage drop and extremely fast switching speeds. The DO-41 through-hole package facilitates standard PCB mounting. Verify thermal management capabilities against the specified junction temperature limits and derating curves. Consider the avalanche capability specification if transient voltage events are expected in the circuit design.
Part Context
This part belongs to the 1N5817, 1N5818, and 1N5819 series of Schottky Barrier Plastic Rectifiers. The 1N5819 variant specifically offers a 40 V reverse voltage rating, distinguishing it from the 20 V and 30 V options available in the same family. All variants share similar mechanical data and feature sets, including guardring protection and matte tin plated leads.
Replacement Considerations
Direct substitutes within the same Vishay series include the 1N5817 and 1N5818, provided their respective reverse voltage ratings meet the circuit requirements. Cross-manufacturer replacements must match the 1 A forward current, 40 V reverse voltage, and DO-41 package constraints.
FAQ
What is the purpose of the guardring in the 1N5819?
The guardring is designed to provide overvoltage protection for the device.
Does the E3 suffix affect the electrical function of the diode?
No, the E3 suffix indicates RoHS-compliant commercial grade material and meets JESD 201 class 1A whisker test requirements, but does not change the electrical function.
