TVS – Diodes: SMP16-E3/85A application field and working principle

A Transient Voltage Suppressor diode (TVS) is a type of diode designed specifically for limiting transient overvoltage spikes from sources outside the immediate system environment, such as those caused by lightning or electrical surges. In normal operation, TVS diodes are reverse-biased, allowing signal current to pass but blocking any spikes or transients. They are frequently used in power supplies and power distribution systems, telecommunication systems, automotive electronics, and other sensitive circuits. The SMP16-E3/85A is one of the many types of transil TVS diodes available on the market. It is a three-terminal monolithic Transient Voltage Suppressor (TVS) diode designed for protection of data lines. It is equipped with an Integrated Interfacial Layer (IIL) on the top surface of its ceramic package to provide additional protection against high electromagnetic field exposure. Its main features include excellent suppression performance, ultra-low capacitance, high surge current capability, and a wide operating temperature range from -55°C to 155°C.The SMP16-E3/85A is particularly suitable for ESD protection of data lines exposed to high electro-magnetic fields. The ultra-low capacitance property of the IIL minimizes interference in signal lines while still providing excellent ESD protection for sensitive IC chips. This combination of features makes it ideal for use in a variety of applications such as automotive electronics, medical systems, telecommunications, and consumer electronics.The working principle of the SMP16-E3/85A can be summed up as follows. In normal operation, the device is reverse biased, allowing free signal current to pass through it but blocking any transient spikes. When a surge voltage is encountered, the impedance of the diode decreases, allowing the transient spike to pass and protecting the sensitive components in the system. The IIL, when exposed to a high electro-magnetic fields, is able to absorb the physical stress, thus providing additional protection against transient surge voltages. This combination of features makes the SMP16-E3/85A an ideal choice for applications in which reliable protection from transient overvoltage spikes is of paramount importance.To summarize, the SMP16-E3/85A is an ultra-low capacitance three-terminal monolithic Transient Voltage Suppressor. Its main features include excellent suppression performance, low capacitance, high surge current capability, and wide operating temperature range. Furthermore, its IIL provides additional protection when the device is exposed to high electromagnetic fields. This combination of features makes it suitable for a variety of applications such as automotive electronics, telecommunications, and consumer electronics. Overall, the SMP16-E3/85A is a reliable and durable choice for reliable overvoltage suppression.
