BD135 NPN transistor in a TO-126 package. Author: Anonimski.

History and origin[]

It was created in the mid 1960s as a universal package for hot running small transistors, tyristors, small rectifiers and small amplifiers.

Construction and orientation[]

It is a oblong shape with 3 metal legs in the bottom. The case is epoxy or resin with a mettal back and a holedrilled in the top.

Usage[]

Hot running transistors, small rectifiers and amplifiers used it.

Heat sinks[]
