Transient Voltage Suppressor (TVS) diodes are essential components used in a wide range of electronic devices. They are designed to protect electronic circuits from voltage spikes, lightning, heavy load changes, and other transient events. The SM6T100AHE3/5B is one of the most popular TVS diodes available today. This article looks at its application field and working principle.

The SM6T100AHE3/5B is a surface mount unidirectional TVS diode with an operating voltage range of 6.0 to 100 Volts. It is intended for protecting sensitive electronic components from voltage transients caused by ESD (electro-static discharge), electrical fast transients (EFT), and lightning. Commonly used in telecommunications, automotive and consumer electronics, the device is also suitable for use in numerous other application fields.

The devices are designed to absorb transient voltage events and to provide thermal protection at elevated temperatures. They feature low capacitance, low VF, and fast response times, making them an ideal choice for pulse suppression. The SM6T100AHE3/5B is also RoHS compliant and offers several advantages compared to traditional diode suppressors.

In terms of working principle, the SM6T100AHE3/5B consists of a reversebiased PN junction diode connected in parallel with a reversebiased Zener diode. The device is designed to provide protection from voltages up to 100V, and it can also be used to suppress voltages up to 6.0 volts in some applications. When exposed to transient voltages, the device will begin to restrike and clamp the voltage spike, limiting its magnitude and protecting the component it is connected to.

When used in conjunction with other components in a circuit, the device helps limit current surges that can damage sensitive electronic components. Thanks to its low capacitance and small size, the device can be used in a variety of applications, from automotive to consumer electronics.

In conclusion, the SM6T100AHE3/5B is a versatile device that offers a number of advantages compared to traditional diode suppressors. It has a wide operating voltage range, is suitable for numerous applications, and features low capacitance and fast response times. This makes the device ideal for pulse suppression and protecting sensitive electronic components from voltage spikes.
