P0080ZA Circuit Protection

P0080ZA Application Field and Working Principle

The P0080ZA Thyristor is a kind of small size, high efficiency and high-speed thyristor developed by STMicroelectronics. It has a structure of 400V/8A and can control 5A direct current with control of 1mA current flow. This product has been widely used in industrial control, LED lighting, renewable energy, solar energy, and other industries.

Application Fields of P0080ZA

P0080ZA is used in almost all fields of electrical engineering and industry. The most common applications include:

• Elevator control systems, in particular on board safety systems
• Large and small equipment and automated systems
• LED lighting systems, renewable energy systems, and solar energy systems
• Power amplifier circuit designs

The P0080ZA is also ideal for high-speed applications, such as networking and computing, and is used in various audio and video devices and consumer electronics.

Working Principle of P0080ZA

The working principle of the P0080ZA is based on a structure that uses two P-channel MOSFETs in series, instead of a single-channel MOSFET. The gate is connected to the B terminal of the thyristor. When the gate current flows, the P-channel MOSFET is turned on, and the thyristor is triggered. The thyristor then allows current to flow through the controlled device.

When there is a reversing voltage (when the anode current is smaller than the P0080ZA built-in current, which is 8A, or when the anode voltage is smaller than the P0080ZA frozen voltage, which is 400V) , the MOSFET automatically turns off, so that the thyristor no longer conducts current. This ensures the safety of user equipment.

Conclusion

The P0080ZA Thyristor, developed by STMicroelectronics, is a small-sized, high-efficiency, and high-speed thyristor with a 400V/8A structure and the ability to control 5A direct current. It is widely used in industrial control, LED lighting, renewable energy, solar energy, and other industries, and is ideal for high-speed applications such as networking and computing.
