TVS - Diodes

TVS is a kind of diode which is transil that works very well when used to protect circuits from overvoltage.

The SZ1.5SMC20AT3G is one of the most popular TVS diode. It has a maximum working voltage of 5.5V. It is mainly used to protect circuits from static electricity, surge pulses, and abnormal voltage. It can also be used as a safety device in high power circuits and systems.

Application Field

The SZ1.5SMC20AT3G is widely applied in many electronic devices such as computers, mobile phones, tablets, and home appliances. It can effectively protect the circuits from high-energy pulse surges.

In particular, it is very useful in the medical, automotive, and industrial sectors, where sensitive devices and components are prone to overload or damage due to surges in the power input. It can prevent short circuit, fire, and smoke caused by over voltage.

The SZ1.5SMC20AT3G is also used in isolators, control circuits, and signal lines. It can help protect the equipment from voltage surges which may be caused by lightning, the switch of the capacitor bank, and other power disturbances.

Working Principle

The SZ1.5SMC20AT3G has a bidirectional operation voltage: the P/N junction is in the on state when the reverse voltage is applied and then changes back to the off state when the forward voltage is applied.

When the external electric field is applied, the P/N junction of the SZ1.5SMC20AT3G will absorb excess electrons to prevent the current from spreading. This prevents the circuits from over voltage and keeps the electric field within a safe range.

Besides, the SZ1.5SMC20AT3G has a high withstand voltage and strong clamping capabilities, which makes it able to protect the circuits from high-energy spikes and surge pulses.

Conclusion

The SZ1.5SMC20AT3G is a TVS diode with high working voltage. It can be used in a wide range of applications, such as computers, mobile phones, tablets, and medical equipment. It has a working principle based on a bidirectional voltage: the P/N junction absorbs excess electrons to prevent the current from spreading. It also has a high withstand voltage and strong clamping ability, which makes it able to protect the circuits from high-energy spikes and surge pulses.
