AK3-170C is a transient voltage suppressor (TVS) diode manufactured by the Taiwan Semiconductor Company, designed to protect other electronic components from voltage overloading due to power surges or transients. The device is constructed to provide surge protection up to 20kV/us in devices, depending upon the model.

The main components of the AK3-170C diode are a silicon substrate, a nitride layer, a polysilicon layer, a nickel gate layer, and a gold layer. The silicon substrate is the basic material on which the device is built. It is generally composed of a high resistance, low oxidation silicon. The nitride layer is an alumina-like insulator that serves to reduce leakage and heat build-up in the device. The polysilicon layer acts as a contact to the silicon substrate. The nickel gate layer is responsible for providing conduction paths as well as serving to increase the device\'s ability to withstand voltage surges. The gold layer on the device helps to reduce current leakage.

The AK3-170C is designed to protect against transient voltage overshoot, or "TVS-events", in electronic components, which occur when there is sudden, large voltage surges. The device is designed with a reverse breakdown voltage of +/- 170V. When an input voltage reaches this level, the device will act to clamp the voltage to a fixed level which will prevent the voltage from going any higher and damaging the device.

The AK3-170C is a popular choice for surge protection in many different applications, including: control systems, embedded systems, telecom equipment, power supplies, industrial automation, and consumer electronics. The device can be used as either over voltage or reverse voltage protection. This makes it an excellent choice for protecting against both overloads and reversed polarity conditions. The device is also designed with low clamping voltage, low leakage current, and low capacitance implementation. This makes it ideal for use in many high frequency applications, such as in RF systems.

The AK3-170C is a low-cost, dependable solution for protecting a wide variety of electronic applications from transient voltage overshoot due to power surges. Thanks to its robust construction and low cost, it is quickly becoming a popular choice for protecting electronic devices in industrial, automotive, and consumer applications. Its low capacitance, low leakage current, and high voltage surge protection make it a dependable choice for users who want the most out of their electronic components.
