Transient Voltage Suppressors (TVSs) are devices that protect electronic components from overvoltage pulses. TVSs protectagainst Electrostatic Discharge (ESD), lightning, inductive switching, electrical fast transients, and overvoltage events. TVSs also protect from overvoltage events caused by inductive switching, lightning, and electrical fast transients. In the industry, TVSs are often referred to as ESD suppressors, diode suppressors, gas suppressors, or self-commutating suppressors. The 5KP100AE3/TR13 is a unidirectional TVS diode. This article will discuss the application field and working principle of the 5KP100AE3/TR13.

Application Field

The 5KP100AE3/TR13 TVS diode is typically used to protect communication and data equipment such as consumer electronics, computers, andvehicles. It can also be used for electronic circuits that require ESD protection. This particular diode has a maximum peak pulse power rating of 0.5 watts and a breakdown voltage rating of 13 volts. It is composed of a silicon junction and is designed to support a maximum working voltage of 10 volts. The 5KP100AE3/TR13 TVSdiode is available in a wide range of packages, including DO-213AA, SMA, and SMB. This provides flexibility for the user to choose the most appropriate package for the application.

Working Principle

The 5KP100AE3/TR13 utilizes a bi-directional protection scheme. This scheme utilizes a Zener diode and a transistor structure to provide bidirectional protection. The Zener diode provides ESD protection, while the transistor ensures that the current is diverted around the diode in the event of an overvoltage pulse. When the voltage across the diode exceeds the breakdown voltage of the diode, the transistor turns on and the current is diverted around the diode. The reasoning behind this is to protect the diode from overvoltage damage. Once the voltage drops below the breakdown voltage, the transistor turns off and the diode is again able to provide ESD protection.

The TVS diode also provides a surge protection function. This surge protection happens when the voltage across the diode exceeds the breakdown voltage for a prolonged period of time. During this time, the diode unleashes a surge of energy that dissipates in the load. This dissipated energy provides a buffer that is able to protect the load in the event of an overvoltage pulse.

In conclusion, the 5KP100AE3/TR13 TVS diode is a unidirectional device that provides ESD and surge protection for communication and data equipment. It is composed of a silicon junction and can support a maximum voltage of 10 volts. The Zener diode provides ESD protection, while the transistor protects the diode from overvoltage pulses. The surge protection function protects the load in the event of an overvoltage pulse. The 5KP100AE3/TR13 is available in a wide range of packages, including DO-213AA, SMA, and SMB.
