1N4448 datasheet


A 1N4448 is Vrm=100V, Fast Switching Diode. Fast switching diodes have a low reverse recovery time, which means that they can quickly switch from the forward bias state to the reverse bias state and vice versa.

The low reverse recovery time of fast switching diodes makes them ideal for use in high-frequency applications such as switching power supplies, pulse generators, and radio frequency (RF) circuits.

These diodes are widely used in electronic circuits due to their fast switching times, low forward voltage drop, and high reliability.
