Not in the comercial product as they ended up being quite a bit more
expensive, also they were a triple darlington and device disipation went up
significantly, I ended up redisigning the product to use a cheap but robust
non darlington bipolar with a new IC that had an integrated antisaturation
driver, worked quite well :)

I used one of the samples in a electronic ignition circuit as thats what
they were actualy marketing them at.
