Im looking at a flash manual and i see the driver takes tip 120 transistors
my board looks like 122
is that ok? (those are also fried on the driver)
i want to replace them and want to know which is best
thanks to the helpers!

Solenoid circuits on the driver board?

If you haven't ordered them yet, use TIP102's instead, more durable in the long term.

yes...need a little schooling on these...just starting to get into the whole pcb thing..
how does the number system work for the tip..???

is it a higher voltage with a higher number (122 would be higher than 102?)
or vice versa?

120's are on the schematics for black knight...what do u suggest for that?
 
There really isn't a system for them to figure out the numbering, but they do have charts and datasheets available. Researching transistors can be pretty annoying sometimes to be honest.

For any of the Williams System 3-7 driver boards, use TIP102's for the solenoid transistors if it lists a TIP120/122 as original. Lamp matrix uses TIP41's and TIP42's, depending on if it's for the columns or the rows.

thats why i just looked at the schematics lol
thanks for the help
