TVS is a special type of diode, which is used to protect electronic circuits from transurses and high-voltage electrical spikes. The BZW50-18, a TVS diode, is an effective protection device used to ensure that electronic systems are reliable under all conditions.

The BZW50-18 has a unidirectional clamping action and is effective across a wide range of transient voltages. It is capable of clamping transurses and spikes up to 18 Volt either when a sudden high voltage is applied directly or when the voltage is coupled on the interface lines of the electronic equipment. Another key feature of the BZW50-18 is its crowbar current capability, meaning that it can safely and quickly shut off any current flow when the voltage exceeds a certain level.

The BZW50-18 is typically used in applications such as Data and Telecommunication equipment, Professional Video, Audio and Broadcast equipment, High-Speed Electrical Interconnects, Computer Interface Cards, Military and Aerospace Systems, and Automotive Equipment.

The working principle of BZW50-18 is based on the zener diode’s avalanche mechanism, which ensures that the device can dissipate the sudden transurs or high voltages. The BZW50-18 has a built-in breakdown voltage, which triggers an avalanche effect when it is exceeded. This action is extremely fast and the voltage is automatically and immediately clamped to a safe level.

There are several advantages to using the BZW50-18 as a protection device for an electronic system. The device is highly reliable, thanks to its compact size and low capacitance. It also has an ultra low turn-on time and is designed with a high heat resistance for optimal performance and durability.

In summary, the BZW50-18 is an effective protection device used to protect electronic circuits from transurses and high-voltage electrical spikes. It has a unidirectional clamping action and is capable of handling transurses and spikes up to 18 Volt. The BZW50-18 is typically used in applications such as data and telecommunication equipment, professional video, audio and broadcast equipment, high-speed electrical interconnects, computer interface cards, military and aerospace systems, and automotive equipment. The working principle of BZW50-18 is based on the zener diode’s avalanche mechanism, which ensures that the device can dissipate the sudden transurs or high voltages.
