I’m just curious as I keep coming across them. They seem to be the latest thing in fast high-voltage diodes, but how do they differ from any other diode?

Here’s an example of one:

Looks like this is marketing wording from Infineon, denominating a diode design that yields a somewhat (100 mV) lower forward voltage.

Ddi you see this, Ian?

That's not what I see. Vf is 1.5V typical.

What is there to see? It links to the Infineon portal...

That's odd, let me see what's wrong with the URL...

There, it was truncated. Should work now.

If comparable diodes have Vf = 1.6 V, 1.5 V is "somewhat (100 mV) lower".
It was not to be understood as "Vf = 0.1 V".

 

It's still a diode. There is no emitter in the transistor sense, but there are games played with structure and doping to increase efficiency. The reference to an emitter is diode-designerspeak for how charge carriers are sourced inside the diode structure: see https://ieeexplore.ieee.org/abstract/document/5543960

 

Designerspeak. I like the term. Is this another Orwellian term?

Similar to the Programmable Unijunction Transistor.

It wasn’t programmable but adjustable.
Nor it was unijunction. It actually had 3 junctions.
Not a transistor either. More like a thyristor.

Not all of use are members of IEEE and can't read it because it is behind a paywall, but we can all have a good snigger in a schoolboy humour sort of way at "Controlled Injection of Backside Holes".
