TVS - Diodes application field and working principle

A TVS (Transient Voltage Suppressor) diode is a common form of surge protection, which is often used to safeguard sensitive electronic circuits. Transient Voltage Suppressor diodes are a special type of voltage regulator that provides overvoltage protection. These devices are used to protect circuits from voltage transients, which are sudden, unpredictable increases in voltage that can cause circuit damage or failure.

TVS diodes are widely used in electronic systems to protect against electrostatic discharge and other forms of electrical transients. They are most commonly used in automotive, industrial, medical, and military applications. TVS diodes can be used in a variety of circuits, such as DC to DC converters, AC to DC converters, analog circuits, and digital logic circuits.

The working principle behind a TVS diode is that when an overvoltage event occurs, the diode generates a reverse leakage current that limits the overvoltage, thereby protecting the circuit. This reverse leakage current is a function of the junction temperature and the TVS diode\'s breakdown voltage. The breakdown voltage of the device corresponds to the maximum overvoltage that it can safely reduce.

The SA8.0AHR0G TVS diode is a unidirectional device that can withstand an ESD (Electrostatic Discharge) pulse of 8kV when triggered with the negative polarity. It can dissipation power of 500W at 8/20µs pulse. This makes it ideal for use in protecting sensitive electronic components. In addition, this device is designed for general purpose EMI/RFI (Electromagnetic Interference/Radio Frequency Interference) protection applications.

The SA8.0AHR0G is a surface mount device, making it suitable for use in small form factor electronics. It has an operating temperature range of -55℃ to +125℃. Its low capacitance characteristics make it ideal for protecting high speed data lines. The SA8.0AHR0G has a peak pulse power dissipation of 1.5kW and a maximum clamping voltage of into 13.3V.

In conclusion, the SA8.0AHR0G is an ideal choice for overvoltage protection in a variety of circuits, from automotive to industrial and from analog to digital. Its performance, reliability and hand seating make it well suited for a variety of applications. This device is capable of withstanding ESD pulses, as well as providing high speed data line protection, making it a must-have for any circuit designer looking for reliable overvoltage protection.
