TVS (transient voltage suppressor) diode is one of the most important components for circuit protection and one of the most applications for it is surge protection. GSOT04-HG3-18 is a kind of TVS diode with low capacitance and integrated into a small package. It is suitable for use in a wide variety of high-speed, high-frequency circuit intergrations in its automotive application field and suited for I/O protection and other power switching protection.

The working principle of a TVS diode is to suppress surge or transient overvoltages that can damage integrated circuits. It is an avalanche junction diode with a breakdown voltage (VBR) higher than the normal working voltage. When an over voltage occurs, the avalanche diode rapidly switches from high resistance to low resistance and thereby supplies a controlled low impedance path for the discharge of transient energy.

When GSOT04-HG3-18 is used for overvoltage protection, it can provide bidirectional protection. Thus, it can prevent ESD (electrostatic discharge) damage and resultant shorts caused by static electricity and AC interference. The drain to source resistance (RDSon) of the GSOT04-HG3-18 is extremely low, which allows it to handle relatively high transient voltages while maintaining low leakage current. Moreover, GSOT04-HG3-18 comes with fast response time and strong reliability, making it an ideal choice for overvoltage protection in a variety of automotive systems.

In summary, GSOT04-HG3-18 is a type of TVS diode highly suitable for protecting automobile circuits against transient over voltage. It provides bidirectional protection and features a low drain to source resistance, making it capable of handling relatively high transient voltages while maintaining low standby current. Furthermore, it has a fast response time and strong reliability, which makes it an ideal choice for overvoltage protection in automotive systems.
