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.
