1301860189, also known as AC-DC over-voltage protection device, is a commonly-used electronic component. It mainly plays the role of voltage protection in the current circuit to ensure the normal operation of the circuit. Generally speaking, it will be connected between the power supply and the secondary equipment to protect the secondary equipment and the circuit from excessive voltage damage.

1301860189 usually has two pins. A pin is connected to the power supply to accept the input voltage of the power supply. The other pin is connected to the load, and its output voltage is the same as the input voltage. If the input voltage is too high, the 1301860189 circuit will open, the output voltage will drop to a minimum, and the load will not be damaged, thus achieving the purpose of protection. It is often used in electromechanical devices, communication instruments, home appliances and other occasions.

1301860189 uses a combination of semiconductor components, linear devices and passive components to realize its effect. Its working principle is as follows: firstly, the zener diode and the linear element are parallel connected in the 1301860189 circuit, and the output of the power is connected to the load, while the zener diode and the linear element are connected to the power supply. The linear element is used to control the overvoltage protection circuit by controlling the base current of the two transistors.

When the voltages at both ends of the zener diode are equal, its current will stop increasing, and the zener diode will be turned off, the linear element will no longer operate and the voltage at both ends of the zener diode will remain unchanged. When the input voltage of the power supply is too high, the zener diode will be charged to conduct, and the linear element will act to control the external circuit. Then the two transistors will turn on and the voltage at both ends of the zener diode will drop, so the overvoltage protection can be achieved.

1301860189 is widely used in various fields, such as communication instruments, mobile phones, lighting systems, medical equipment, power systems, home appliances, etc. It can provide efficient protection against overvoltage by limiting the output voltage of the power supply and ensuring the safe and reliable operation of the equipment. In addition, 1301860189 can be used for surge protection, noise filtering and so on. It is an indispensable protective device in the circuit.

In summary, 1301860189 is a commonly used protection device, which uses a combination of semiconductor devices, linear devices and passive components to provide effective overvoltage protection. It is widely used in various fields, such as communication instruments, medical equipment, power systems and home appliances, and can provide efficient protection to ensure the safe and reliable operation of the equipment.
