TVS diodes are semiconductor protection devices that can be used to protect against transient overvoltages in a wide variety of electrical systems. The 5KP18HE3/73 is a type of TVS diode from STMicroelectronicswhich combines high pulse current capability with good clamping performance. It can be used in applications such as overvoltage protection in automotive electronics, computer systems, consumer audio/video equipment, telecommunication systems, and industrial equipment.

The 5KP18HE3/73 uses a simple can-type package design which provides excellent thermal performance and also provides protection against environmental stress due to dust and moisture. It offers low junction and clamping capacitance, as well as fast response times. It can operate over a wide range of temperatures, from -55°C to 150°C, and it has a peak pulse power of 18000W.

The working principle of a TVS diode, like the 5KP18HE3/73, is based on a reverse-biased junction diode connected in series with a resistor. When the voltage across the diode exceeds its reverse breakdown voltage, a low-impedance path is created which clips the incoming voltage and prevents its propagation to the protected device. In normal operation, the low-impedance path is blocked until the excess overvoltage is detected. This type of diode is also known as an avalanche diode, and it provides fast response times and low capacitance characteristics.

The 5KP18HE3/73 is just one of the many types of TVS diodes available for use in overvoltage protection applications. These diodes provide a fast response time and can handle high peak power levels while still maintaining good clamping performance. They are ideal for use in automotive electronics, computer systems, consumer audio/video equipment, telecommunication systems, and industrial equipment.
