    1N4148 is an incredibly fast responding diode. The recovery time is around 4ns. Which means it can come out of conducting state to blocking state in 4ns. If you consider the 1n4001 another commonly used diode the recovery time is around 2uS.

    Which is around 500 times slower than the 1N4148. I generally use 1N4148 diodes for analog frontend protection circuits. If you want to protect a differential amplifier from a sudden transient voltage you can use 1n4148.
