As shown in Figure a, it uses non-linear relationship of the piezoresistor to achieve the protectionfor the transistor. In Figure b, c, due to induced over-voltage suppression is below the specified value, C ~ E poles will not exceed the specified threshold voltage,so itcan play a protective role of the transistor.
