Working Principle of GSOT04C-G3-18

The working principle of GSOT04C-G3-18 is based on a gas breakdown phenomenon between two electrodes. When the voltage across the anode and cathode terminals exceeds its breakdown voltage, and ionization of the gas between the electrodes will occur and allow current to flow. Once the transient voltage passes, the dielectric property of the gas will be restored and the current flow will stop.

The GSOT04C-G3-18 diode array has two separate protection zones for positive and negative polarity. This allows it to protect two signal or power lines with one diode array. The superior capability and robust design of the device makes it an optimal choice for automotive, industrial, medical, commercial, consumer, networking, telecommunications, defense, and aerospace applications.

Furthermore, the diode array is capable of suppressing electromagnetic interference (EMI) as well as EMI related transient signals owing to its fast response time. GSOT04C-G3-18 provides an effective protection level and can withstand up to 8kV ESD peak pulses. The device features an open drain design, and it can be driven with a 3V power supply for various protection levels.

Conclusion

In conclusion, GSOT04C-G3-18 is a highly desirable TVS diode array suitable for a variety of applications due to its wide applicability, robust design, superior performance, and EMI/ESD protection capability. It has two protection zones and can be driven with 3V for various protection levels. With it’s fast response time and high ESD peak pulse energy, it is an optimal choice for designers looking for a reliable surge protection solution.
