Description
The 1N4148 small signal diodes are general purpose fast switching diodes used for small signal rectification. KEY FEATURES OF 1N4148 SMALL SIGNAL DIODE: General purpose small signal diodes High switching speed of < 4nS Up to 100V reverse voltage Up to 0.3A continuous current (4A surge) These are general purpose small fast switching diodes used for small signal rectification, meaning they only allow current to flow in one direction. They can handle up to 100V reverse voltage and up to 300mA of continuous current. Due to their modest power handling, these are mainly useful in digital or signal processing circuits. The 1N4148 are polarized devices with a black band denoting the cathode end of the diode.
