PTC component and overvoltage protection component work together to complete the following jobs: 1, Aiming at the large current which perhaps damage FET and batteries, it protects the current. 2, When it is reversed polarity, PTC action is used to limit the overcurrent produced by the zener diode positive conduction. 3, When the overvoltage component is protecting the voltage overload, the conduction current is limited by component.
