Dear all ,
I cut in half a black transistor in a old Phillips TV and I have found a gold plated layer (no gold bonding wires apparently) underneath the silicon die and a metallic plating over the 3 metallic terminals (see the picture below), could it be silver?
Thanks for your attention, have a good day!
