TVS diodes are an essential component in any electronic device. They protect against overvoltage transients by clamping the voltage to a safe level. They also protect against short-circuits and excessive current surges. The P4KE220ATR is a Transient Voltage Suppressor (TVS) diode specifically designed for industrial applications. The diode is used to protect against severe voltage overloads from electrostatic discharges, lightning strikes, and any other extreme voltage surge.

The P4KE250ATR is a two terminal device typically constructed from two diodes connected back-to-back. The two diodes face away from each other, such that their anodes are connected together and their cathodes are connected together.

The working principle of the P4KE220ATR is based on the same principles of traditional PN-junction diodes. When the P4KE220ATR is subject to a voltage surge, the PN-junction will quickly become forward-biased and the diode will start conducting the current. The diode will quickly reach its maximum safe forward current and will clamp the voltage to the diode’s peak reverse voltage (PRV) rating.

The most common application for the P4KE220ATR is the protection of industrial computers, controllers, and equipment against high voltage transients. Specifically, it is designed to be used in circumstances where there is a risk of electrical surge induced damage. It is particularly important for long-distance communication lines, such as telephone, data, and CATV. The P4KE220ATR is also well suited for use in power supplies, such as DC-DC converters, and any other devices that require surge protection.

The P4KE220ATR is able to efficiently and safely protect against both positive and negative voltage surges. It has a reverse breakdown voltage clamping capability of 200V, and can conduct up to 140A of peak pulse current—which is significantly higher than most other standard TVS diodes. In addition, the P4KE220ATR has a robust design that can tolerate up to 10,000V of electrostatic discharges.

Overall, the P4KE220ATR is a cost effective and reliable solution for providing surge protection to industrial electronic devices. Its reverse breakdown voltage and peak surge current capabilities make it an ideal choice for applications such as data communications, power supplies, and CATV systems.
