Vishay’s take on the 1N4148 data sheet (PDF), describing it as a switching diode. ... They have none of the special skills you’d find in tunnel, Gunn, varicap, Zener, and avalanche diodes, ...

Varactor (or “varicap”) ... There are other benefits to using a DAC to bias a varactor diode. For example, multiple-output-channel DAC devices can be used in a multistage application.

The history of the diode is a fun one as it’s rife with accidental discoveries, sometimes having to wait decades for a use for what was found. Two examples of that are our first two topics: t… ...

The four-layer diode was the key to William Shockley's plan to revolutionize AT&T's phone system. It was a great device in theory, but not in practice -- at least not at the time when Shockley ...
