Default Interest for genuine Semisouth SJEP120R100 curve tracer matched pairs & quads

.
We purchased a sizeable stock quite a few years back, and are finally planning to get them matched in 2019 using our own curve tracer.
Matching conditions will be 24V, 0~2A continuous mode on 60C (+/-1C) heater block.
F5 power amplifier

We want to know how much interest there still is before deciding how many to match in the first round.
And whether pairs or quads are desired.
Would be great if you could help us get a feel.

Will take a while to match them all.
The heater block alone takes 3 hours to reach steady state temperature.


Thanks in advance,
Patrick

> how much for a Quad ?

Depends on how much matching rejects we have.
If we just measure single point Vgs, we probably and line them in descending order, we shall have little or no rehject.
But if we match by curve traccer, we probably have 25% reject or more.
