Draw the symbol of scr
WebA PUT (programmable unijunction transistor) is a 3-terminal 4-layer thyristor acting like a unijunction transistor. An external resistor network “programs” η. The intrinsic standoff ratio is η=R1/ (R1+R2) for a PUT; substitute R B1 and R B2, respectively, for a unijunction transistor. The trigger voltage is determined by η.
