Three 1N4148 diodes in glass DO-35 axial package. The black band on the right is the cathode side.Diode schematic symbol vs cathode marking on the package.
The 1N4148 is a standard silicon switching signal diode. It is one of the most popular and long-lived switching diodes because of its dependable specifications and low cost. Its name follows the JEDEC nomenclature. The 1N4148 is useful in switching applications up to about 100 MHz with a reverse-recovery time of no more than 4 ns.
