Television Surge Suppression Diodes, also known as TVS diodes, are semiconductor protection devices used to protect sensitive electronics from voltage transients and lightning. The PGSMAJ28A is an innovative TVS diode designed to protect semiconductor devices from damaging voltage spikes and lightning strikes.

TVS diodes function similarly to zener diodes, but often incorporate additional technologies such as voltage breakdown and current commutation for improved protection and robustness. The PGSMAJ28A TVS diode utilizes a unique combination of active and passive components to provide enhanced protection from ESD, EFT, and lightning. This combination of technologies ensures reliable protection of voltage-sensitive semiconductor devices and other components.

The PGSMAJ28A is ideal for a wide range of applications including automotive, industrial, and consumer electronics. The device is designed for mounting on the printed circuit board and provides fast and reliable transient protection with peak pulse power rating of >28A (8/20µS). The diode has a low clamping voltage of 42V which provides superior protection in high voltage environments. Furthermore, the diode is designed to be compatible with various types of packaging including SMD, DIP, and mini packages.

The PGSMAJ28A is a miniaturized device designed for mounting directly to the printed circuit board. It consists of two active components: a Zener diode and a silicon avalanche diode. The Zener diode is configured to protect from abnormally high voltages, while the avalanche diode is configured to protect from abnormally high currents. Additionally, a passive component known as the varistor (or metal oxide varistor) is used to provide protection from transient voltages and lightning.

When the device is exposed to high transient voltages, the Zener diode will begin to conduct, reducing the voltage applied to the protected device. As the voltage exceeds the Zener diode\'s threshold voltage, the avalanche diode will trigger, limiting the current to a safe level. At the same time, the varistor acts to limit any further increase in voltage or current, providing an additional level of protection.

The PGSMAJ28A offers superior protection from ESD, EFT, and lightning when compared to other TVS diodes. The device has a high peak pulse power rating which ensures protection during even the most severe transient events. Additionally, the low clamping voltage level of 42V ensures excellent protection even in high voltage environments. It is also extremely reliable and easy to install, making it ideal for applications in the automotive, industrial, and consumer electronics industries.

In conclusion, the PGSMAJ28A is a highly advanced TVS diode designed to provide superior protection from ESD, EFT, and lightning. It utilizes a unique combination of active and passive components to provide enhanced protection in high voltage environments. The device is designed for mounting directly to the printed circuit board and offers fast and reliable transient protection with a peak pulse power rating of >28A (8/20µS). It is ideal for a wide range of applications including automotive, industrial, and consumer electronics.
