Temperature Triggering

At high temperature the leakage current  of junction J2 increases. This leakage  current is collector  current of tr1 and Tr2. So rise in temperature  increases leakage current  which is  responsible  to increase IC1 and IC2  then (α1 + α2  ) tends to unity  and thyristor  will get tumed on.
