1N4148 Fast Switching Diode

The 1N4148 is a fast switching diode built for circuits where speed and precision matter more than raw power handling, commonly used in signal switching, clamping, and general logic-level applications. Its compact size and reliable performance have made it a staple component in electronics kits and hobbyist parts bins for decades.

With a peak repetitive reverse voltage of 100V and an RMS reverse voltage of 75V, this diode offers solid protection margins for signal-level circuits, while a peak forward surge current of 2A gives it useful headroom for brief current spikes. Its notably fast reverse recovery time of just 8 nanoseconds makes it well suited to high-speed switching applications where a slower diode would introduce unwanted delay.
