Probably why we don't see that configuration very often.
Except when a lower-threshold pair is clearly shunting another, and said pair is on a switch. That is rather popular.
PS: had a look at some figures on I-V charts. Devices in parallel means same voltage, twice the current over voltage if the devices were identical. As far as I can tell, if tolerances are tight enough, the result would be a sharper knee (to a maximum of 45°+tangent to the initial graph).

I've always had some kind of crackly/sputtery decay when using LEDs as clippers. Silicon/Mosfets/Ge were always smoother. Sharper I-V response?

rezzonics, am definitely looking forward to hearing your schottky shin-ei. don't keep us in suspense.
dr nomis, you posted this diagram of the jcm diode configuration you used to produce those oscilloscope readings.
it's pretty weird looking when all i've thought about re clipping diodes to date has been the classic 'pair' (and variations of using different types and values in series but keeping the basic restricted 'two way traffic' principle). what is the diode across the middle of your configuration doing? apologies if it's a newbie-type question. i still am in most ways.
