As seen below, I have a circuit that turns on +12V to the EN pin of a LM53601 buck converter when the +6V DC component in a car speaker wire is detected (bridged output). This works fine.
But I am a bit confused when reading the specifications for the PNP and I need some help understanding how much voltage the 3906 can withstand. In my current circuit, the +12V from the battery has TVS diode protection, clamping the voltage at 36V. It also has a 200V Schottky in series.
Will a transient of 36V at Q2 emitter destroy it?
