It is shown that variation of the temperature of the ambient medium can produce, in addition to a fall in the static turn-on current of a thyristor, a more complex behavior of this current: an initial descent to some minimum may be followed by a rise and another fall. This effect is atrributed to the high level of carrier multiplication in the collector p-n junction of the thyristor at a temperature corresponding to the turn-on current minimum. It is also due to the different temperature dependences of the current gains of the two transistors (which together form the equivalent circuit of a thyristor) and of the multiplication coefficients of the collector p-n junction.
