TVS diode is a kind of transient voltage suppressor diode. It is also known as the suppressor diode, anti-surge diode, clamp diode, and transient diode. It is an electronic device that helps protect sensitive electronic parts from damage caused by transient overvoltage, such as Electrostatic Discharge (ESD or ESD event) and conducting surges. In this article, we\'ll look at a STRVS118X02C TVS diode and discuss its many applications as well as its principles of operation.

Introduction to STRVS118X02C TVS diodes

The STRVS118X02C is a low capacitance, dual-channel, voltage surge protection device. It is a two-channel, bi-directional, Unidirectional Transient Voltage Suppressor (TVS) diode that protects vulnerable automotive and industrial applications from high voltage surge. The diode\'s fast response time and -5.6 to 5.6 V working voltage range make it ideal for use in high power and high side voltage applications.

The package size of the STRVS118X02C is only 1.0 mm x 2.0 mm x 0.5 mm. The maximum peak pulse power rating is 20 A. The clamping voltage is the reverse of the breakdown voltage. It is designed for automotive and industrial applications such as industrial process control systems, automotive electronic circuit protection, communication systems, AC power supplies, and numerous other applications.

Applications of STRVS118X02C TVS diodes

As mentioned previously, STRVS118X02C TVS diodes are designed for automotive and industrial applications to protect sensitive electronic components from ESD, lightning, or power cross surges. These diodes have a fast response time and high peak power ratings which make them ideal for use in high power applications. Here are some of the main applications of STRVS118X02C TVS diodes:

• Automotive Electronic Circuit Protection - The fast response time and wide working voltage range make it ideal for use in automotive electronic circuits, such as engine control units, ignition coils, ECU protection boards, and other automotive electronics.
• Industrial Process Control Systems - The high peak power ratings and low capacitance make it an ideal protection device for industrial process control systems, such as PLC systems, solenoid valves, servo motors, and machine vision systems.
• Communication Systems - The low capacitance makes it an ideal protection device for communication systems, such as high speed data converters, telecom, and laptop ports.
• AC Power supplies - The wide working voltage range makes it ideal for use in AC power supplies, such as switching mode power supplies.

Working Principle of STRVS118X02C TVS diode

The STRVS118X02C is a bidirectional TVS diode that works by limiting the surge voltage and clamping the surge current. When the surge voltage exceeds the diode\'s breakdown voltage, it will begin to conduct current from both the anode and cathode. The diode then acts as a short circuit and clamps down the surge voltage across it. The peak voltage is limited to the breakdown voltage of the diode, which is -5.6 V to 5.6 V, and the peak current is limited by the reverse leakage current of the diode.

Once the surge has subsided, the diode stops conducting current and the voltage across it returns to 0 V. When operating within its working voltage range, the diode will protect vulnerable components from surge damage.

Conclusion

STRVS118X02C is an excellent TVS diode for protecting sensitive components from damage caused by transient overvoltage. Its small package size, fast response time, and wide working voltage range make it ideal for use in automotive and industrial applications. This diode works by limiting the surge voltage and clamping the surge current when the surge voltage exceeds its breakdown voltage.
