ABSTRACT:
A heat sensitive switching device comprises at least three pn junctions between a pair of main electrodes to change from the OFF state to the ON state under rising temperature in at least one quadrant of the main voltage - main current characteristic curve wherein a region for shortening the life-time of carriers is formed at a part of the pn junction which causes the reverse bias in the OFF state.
