1N4148 Diode

High-speed switching diodes produced in planar technology and enclosed in hermetically sealed leaded glass SOD27 (DO-35) packages. The maximum current carrying capacity of the IN4148 Diode is 300mA, and it can withstand peaks of up to 2A. The main function of this diode is its fast recovery time of 8ns at a forward current of 10mA, hence this diode is used in applications where fast switching is required.   Because the 1N4148 diode is primarily used for rapid switching, it is called as a switching diode. These diodes provide the same functions as a standard switch. Under a fixed voltage, these diodes have high resistance, whereas they have low resistance above the fixed voltage. This type of diode is easily available in a small package at a low cost. As a result, this diode can be chosen based on its fastest reverse recovery time and power dissipation, which ranges from 80 milliwatts to one kilowatt. It is widely used in a variety of switches that have a very fast operation for switching, high-speed rectification, residential and telecommunications industry protection, and so on.
