Overvoltage protection circuit in TV:
115V is the main power supply voltage of the TV. When the output voltage of the power supply is too high, D is turned on, and the transistor T is turned on. The collector potential will change from the original high level (5V) to the low level, and the voltage through the standby control line. Put the TV into standby protection.

Arc suppression circuit:
When a suitable Zener diode is connected in parallel on the inductor coil (or the same principle as a normal diode), when the coil is turned off, the high voltage generated by the release of electromagnetic energy is used by the diode. Absorbed, so when the switch is turned off, the arc of the switch is eliminated. This application circuit is used more in the industry, such as some higher power electromagnetic control circuits.
