Overview
The 1N5819A-01 is a Schottky barrier rectifier manufactured by Diodes Incorporated. It features an average forward rectified current of 1 A and a maximum repetitive peak reverse voltage of 40 V. The device utilizes a DO-41 axial leaded package for through-hole mounting. Key electrical characteristics include a low forward voltage drop of approximately 900 mV at rated current and a high surge current capability of 30 A. The component operates within a temperature range of -65°C to +125°C junction temperature.
Feature Summary
- Schottky barrier construction for fast switching and low power loss
- High surge current overload capability for robust operation
- Low forward voltage drop to improve system efficiency
Applications
- Power supply rectification in consumer electronics
- Free-wheeling diodes in DC-DC converters
- Reverse polarity protection circuits
Procurement Notes
Verify the specific manufacturer designation, as the 1N5819A-01 part number is associated with Diodes Incorporated but may be listed as obsolete or discontinued in certain distributor catalogs. Confirm RoHS compliance status and moisture sensitivity level (MSL) requirements against your assembly process specifications before finalizing procurement orders.
Selection Notes
Select this component when a standard 1A Schottky rectifier is required for low-voltage applications. Ensure the circuit design accounts for the 40V reverse voltage limit and the thermal management needs associated with the DO-41 package. Verify that the 30A surge rating meets the inrush current demands of the target application.
Part Context
This component belongs to the widely used 1N581x series of Schottky rectifiers. It serves as a discrete semiconductor solution for general-purpose rectification tasks. The DO-41 package provides a reliable mechanical interface for automated through-hole assembly processes commonly found in traditional electronic manufacturing lines.
Replacement Considerations
Direct substitutes include other manufacturers' 1N5819 variants such as those from Taiwan Semiconductor or Vishay. Ensure pinout compatibility and identical electrical ratings are maintained when cross-referencing alternative sources for this specific rectifier function.
