Bianca Posted October 28, 2020 Share Posted October 28, 2020 Hi @Zoran, Those transistors have the collector shorted to the base and they function as a diode. The circuit there is basically a clamping circuit to limit the over and under voltage. Regards, Bianca Link to comment Share on other sites More sharing options...
