1N4148 Signal Diode

The 1N4148 is a standard silicon switching signal diode. It stands out amongst the most well known and enduring switching diodes as a result of its dependable features and it's inexpensive. Its name comes from the JEDEC classification. The 1N4148 is helpful in switching applications up to around 100 MHz with an invert recuperation time of close to 4 ns.

As one of the most well-known mass-produced switching diode, the 1N4148 supplanted the older version, the 1N914. A major difference between them is in their leakage current rating at 25°C: 25 nA @ - 20V versus 5 µA @ - 75V, with greatest leakage for both at 150°C to be 50 µA @ - 20V. Today makers create the 1N4148 and offer it as either part number. It was second-sourced by numerous producers; Texas Instruments recorded their model of the diode in an October 1966 information sheet. These types of diodes have a persisting ubiquity in low-current applications.[4][5]

Despite the fact that the first 1N4148 and 1N914 existed just in a pivotal bundle, the 1N4148 was later repackaged into different surface-mount bundles.
