TVS-Diodes Application Field and Working Principle

TVS-diodes, also known as Transient Voltage Suppression (TVS) diodes, are a type of semiconductor device with a construction similar to that of a diode. The main purpose of this device is to protect electronic apparatus from damage due to high voltage and current spikes, such as induced lightning, electrostatic discharge (ESD), and electrical transients. They are widely used in power systems, telecommunications and other industries.The main function of a TVS diode is to provide overvoltage protection and general protection against electrical transients. The key components of a TVS diode include a Zener diode and a thyristor which provide a very fast response in case of an overvoltage or high current spike. When the input voltage exceeds the rated voltage of the diode, the device will be turned on and the input signal will be shunted to ground. This shunting mechanism not only provides protective measures against current spikes, but also helps to reduce the voltages and currents to safe levels. One type of TVS diode is the 15KPA64CATR which is specifically designed for use in microcomputer systems. This type of diode is ideal for applications requiring high surge capability, ultra-low capacitance, and low EMI/RFI. It has a nominal breakdown voltage of 15kV, a typical clamping voltage of 17.5kV, and a typical capacitance of 360pF. The device is also capable of handling high peak power levels up to 30kW. The 15KPA64CATR TVS diode can be used with various types of microcontroller systems such as MCUs, microprocessors, PICs, micro-controllers, and DSPs. It is compatible with some of the leading semiconductor manufacturers such as Texas Instruments, Intel, STMicroelectronics, Renesas, and NXP. This type of diode can be used in applications involving electrostatic discharge, electrical power interference, and lightning-induced overvoltages. It is also very effective in protecting circuits from damage due to overvoltage and short circuit conditions.The working principle of the 15KPA64CATR TVS diode is based on the so-called avalanche breakdown effect. When an electric current passes through a junction between two different mediums, an avalanche breakdown occurs if the voltage exceeds the breakdown voltage of the specific materials. This breakdown results in the formation of a reverse-biased p-n junction which is capable of carrying current in the reverse direction. As a result, current will be prevented from reaching the sensitive device or circuit and the voltage will be clamped to a safe level.In conclusion, the 15KPA64CATR TVS diode is a versatile device designed for use in microcomputer systems. It provides excellent protection from high-voltage or high-current spikes and is capable of handling peak power levels up to 30kW. This type of TVS diode can be used with various semiconductor manufacturers and is perfect for applications which require ESD protection, lightning-induced overvoltage protection, and general fault protection.
