TVS – Diodes

TVS – diodes, otherwise known as Transient Voltage Suppression diodes, are solid, two leaded nonlinear devices that are used to protect an electrical circuit from high voltages. These devices are deployed when the expected power surge or transient voltage in a specific circuit is in excess of the power source or the rated amount. The PGSMAJ22A R3G is the latest addition to the TVS - Diode family and provides quick and efficient protection from extreme voltages.

PGSMAJ22A R3G application field and working principle

The PGSMAJ22A R3G is an advanced TVS - diode that is particularly useful in a number of power supply and lighting applications. This device works by clamping the signal voltage to a safe level as soon as it detects any voltage that is higher than the rated level which can cause irreparable damage to the connected devices. It can be implemented with two leads or with a surface mount configuration.

The PGSMAJ22A R3G is a great choice for power supply and lighting applications as it has very low failure rates and exceptional durability even when subjected to extreme conditions. It is able to switch very quickly and can tolerate transients or spikes with an excess of 2.5kV. It also has very low leakage current characteristics and offers plenty of protection against reverse voltages. Additionally, the device is comfortable in working temperature ranges of -55ºC to 150ºC, which is great for various automotive applications, military applications and other large-scale industries.

The working mechanism of the PGSMAJ22A R3G comes down to the junction barrier that it employs. This type of device mechanism creates a fifth terminal which can be quickly subjected to the clamping voltage. This occurs during high voltage occasions and the diode is able to sense the exact voltage that is in excess of the rated voltage. As soon as this sensing takes place, the device acts as a short circuit and helps in dissipating the extra energy that comes from the voltage spike. Once the transient voltage is gone the device reverts back to its original condition and enables the circuit to function as normal.

Conclusion

In conclusion, the PGSMAJ22A R3G is a powerful and reliable TVS - diode that can be used to protect a variety of applications from high voltages and transient surges. It works by employing a junction barrier and quickly clamping the voltage to a safe level. The device offers numerous advantages like low failure rates, exceptional durability, fast switching speeds and tolerance of up to 2.5kV. This makes the PGSMAJ22A R3G perfect for large-scale industries, the military, and the automotive sector.
