Vishay’s take on the 1N4148 data sheet (PDF), describing it as a switching diode.. When looking across the discrete components in your electronic armory, it is easy to overlook the humble diode ...

When the integrated circuit was invented in 1958, it eclipsed the four-layer diode's capabilities and any market for the diode quickly dried up. Four-layered semiconductors are, however, used today.

J1 is a momentary switch that initiates the test. S1 reverses the polarity of the signal to the diode under test (DUT), D3, to check the device in forward and reverse modes.
