Hello readers here we will discuss Introduction to 1n4148 Datasheet: Pin Configuration, Features, Applications. diode is an electronic component that uses ac ac to DC conversion. This current conversion is called rectification and the circuit used is called rectifier as current flows in the diode in a single direction which means from anode to cathode. The cathode terminals are found through the grey bar on the diode.
1N4148 diode PN junction diode has the highest current about three hundred milliamperes. It can handle the highest two ampers current. its main feature is a high-speed recovery time of eight neno seconds at the forward current of ten milliamperes. So it is best for use in high-speed switch applications. Here we will discuss working, features, and other parameters. So let’s get started with Introduction to 1n4148 Datasheet
Introduction to 1n4148 Diode
The 1N4148 is a silicon switching signal diode. it is very famous and mostly used switching diode since it has low cost and dependable features. Its name is accordin to JEDEC nomenclature. it is best to use for a switching frequency of 100 MHz with a reverse recovery time not larger than four nanoseconds.
It was made by Texas Instruments in 1960. It was registered at JEDE in 1968 as a silicon switching signal diode for military and industrial uses. It is mostly used in low-current uses projects. The most commonly made switchin diode the 1n4148 replaced the older 1n491 but they can used as interchangeable or replacements of each other. They are different in leakage current features.
