SZSMF05T2G is a common type of low capacitance, two-channel TVS diode, designed for circuit protection against high-energy ESD events, as well as for prevention of EFT, lightning and power induction related surge pulses. The device is available in a SOD-123 package, and its low capacitance allows it to be used for high-speed data interfaces with relatively short rise times.

The two-channel SZSMF05T2G is designed to be used either as a stand-alone component, or in be integrated into a wider protection system. When integrated into a larger system, the device performs two functions. Firstly, it limits the ESD current, by triggering two separate avalanche diodes in series in the event of an ESD event. Secondly, when this occurs, the device suppresses the remaining voltage surge, allowing the more sensitive components on the circuit board to remain protected.

In terms of the working principle, when an ESD event occurs, the ESD current is triggered by the triggering voltage, which is created by the avalanche of electrons. This voltage is known as the device’s peak pulse power, and is specifically calibrated to prevent the ESD current from damaging sensitive components on the circuit board. When the voltage drops below the device’s peak pulse power, the avalanche is stopped, ensuring that any remaining voltage surge is suppressed.

For increased protection, the SZSMF05T2G can be used in conjunction with a variety of other components, including fuses, TVS diodes, and varistors. The most common application for the two-channel device is to protect SI and USB interfaces from ESD damage. Due to its low capacitance, the device can be used to protect high-speed data interfaces, as well as low voltage systems with relatively short rise times.

The SZSMF05T2G is also a popular choice for analog and digital signal protection, and is used in a variety of commercial and military applications, such as telecommunications, automotive, industrial, consumer electronics, and medical equipment. In addition to these, the device can also be used for general purpose ESD and surge protection in various applications.

Overall, the SZSMF05T2G is an ideal solution for low capacitance, two-channel TVS diode applications, offering fast response time, low capacitance, and the necessary protection from ESD, EFT, lightning, and power induction related surge pulses.
