1N5819

Description

The onsemi 1N5819 is a Schottky rectifying diode, packaged in a DO-41 plastic package. It has a maximum voltage rating of 40V and a current rating of 1A. This device features extremely low forward voltage drop, low stored charge, and majority carrier conduction, making it suitable for applications where power loss and efficiency are critical. The 1N5819 is commonly used in power supplies, rectifiers, voltage regulators, battery charging circuits, reverse polarity protection circuits, DC-DC converters, solar panel regulators, automotive applications, uninterruptible power supplies (UPS), and LED lighting systems. It is available in tape and reeled packaging for automated assembly processes.

Package

The package type of 1N5819 is DO-41 (Plastic).

Pinout

The 1N5819 is a Schottky rectifying diode, not a component with pins or functions like an IC chip. It's a discrete semiconductor device that can be used in various applications such as power supplies, rectifiers, voltage regulators, and battery charging circuits. As a diode, it has two terminals: the anode (positive) and cathode (negative). The function of this diode is to allow current to flow in one direction (from anode to cathode) while blocking current from flowing in the opposite direction.

Manufacturer

The manufacturer of the 1N5819 is ON Semiconductor, which is a leading independent supplier of semiconductor-based system-level solutions.
