SMCJ170C is a type of TVS - Diodes that is ideal for protecting sensitive electronic equipment from overvoltage transients. It has a wide range of applications in automotive, consumer, industrial and communication applications, and is capable of suppressing transients as high as 170V. The device has an industry-standard surface mount package that allows for easy installation and design integration.

The SMCJ170C is a unidirectional device, meaning it conducts current in one direction and blocks current in the other direction. This feature makes it ideal for use in a variety of applications, including overvoltage protection of power supplies, general-purpose protection of controlling logic, and in-circuit protection of communication ports and buses. The SMCJ170C provides fast response times and low leakage current (which is important for power protection).

The working principle of SMCJ170C is based on the avalanche breakdown of a semiconductor junction. When voltage between the anode and cathode of the diode exceeds the critical breakdown voltage (also known as the avalanche voltage), a large current starts to flow. This large current increases exponentially, causing the junction temperature to rise and the diode to break down. The diode then clamps the voltage to a level that is safe for the connected circuit. It is this breakdown phenomenon that makes SMCJ170C ideal for overvoltage protection applications.

In applications where a large transient voltage is expected, the SMCJ170C can be connected in parallel with a low-capacitance capacitor for additional protection. This configuration can provide additional protection and lower the total capacitance of the transient voltage protection circuit. The SMCJ170C is also RoHS compliant, making it suitable for use in a variety of industries and applications.
