I have an exicom phone system with a faulty battery back switch, which
is a BDX54C pnp darlington transistor. It's in a TO-220 package, 100v,
8A, 750 hfe. It's being used to switch between mains-derived 24V DC and
battery power at mains failure, in a very simply circuit.
Can anyone suggest a possible replacement?
Thanks, Peter
