1N8147 Diode - Encyclopedia Entry

Product Overview

The 1N8147 diode is a semiconductor device belonging to the category of rectifier diodes. It is commonly used in electronic circuits for its ability to allow current to flow in only one direction, making it suitable for converting alternating current (AC) to direct current (DC). The diode's characteristics include low forward voltage drop, high surge current capability, and fast switching speed. It is typically packaged in a small, cylindrical glass or plastic enclosure with two leads. The essence of the 1N8147 lies in its role as a crucial component in power supply and signal processing circuits. It is commonly available in bulk packaging with varying quantities.
