1N5819 Datasheet – 1A, 40V, Axial Lead Rectifiers – Onsemi

Part Number: 1N5819


Schottky Barrier Rectifier, 1.0 A, 40 V

Manufacturer: ON Semiconductor




The Schottky Rectifier employs the Schottky Barrier principle in a large area metal-to-silicon power diode. The Schottky Rectifiers state-of-the-art geometry features chrome barrier metal, epitaxial construction with oxide passivation and metal overlap contact. It is ideally suited for use as rectifiers in low-voltage, high-frequency inverters, free wheeling diodes and polarity protection diodes.
