Introduction

The PGSMAJ90AHM2G is a TVS (Transient Voltage Suppressor) diode, which is a type of device designed to protect sensitive electronic components from damage due to transient voltages or currents. This device has an effective threshold voltage of 9V and a maximum holding current of 2A, making it well suited for many applications. In this article, we’ll discuss the application field and working principle of the PGSMAJ90AHM2G.

Application Field of PGSMAJ90AHM2G

The PGSMAJ90AHM2G is commonly used in high-end electronic devices such as digital cameras, computers, cell phones, and other consumer electronics. It is also commonly used in industrial control circuits and in industrial machines. Its low voltage and high current rating make it an ideal choice for many applications.The PGSMAJ90AHM2G can also be found in automotive and motor control circuits, where its low voltage and high current rating make it an excellent choice for the protection of these circuits. Additionally, it is also used in aviation and aerospace applications where its low voltage and high current rating make it an excellent choice for the protection of important components.

Working Principle of PGSMAJ90AHM2G

The PGSMAJ90AHM2G is a TVS diode, which is a type of device designed to protect sensitive electronic components from damage due to transient voltages or currents. This device is designed to clamp the voltage across its terminals to a safe level, allowing current to pass but preventing excessive voltage from damaging sensitive components.When the voltage across its terminals exceeds its threshold, the PGSMAJ90AHM2G will begin to conduct, allowing the excess voltage to pass through it. The device will then act as a current limiter, limiting the amount of current that can pass through the device and, thus, protecting more sensitive components downstream.

Conclusion

In conclusion, the PGSMAJ90AHM2G is an excellent choice for the protection of electronic components in a wide variety of applications. It is designed to clamp the voltage across its terminals to a safe level, allowing current to pass but preventing excessive voltage from damaging sensitive components. Additionally, it can also be used in automotive and motor control circuits, in industrial control circuits, and in aviation and aerospace applications, thanks to its low voltage and high current rating.
