TVS diodes, also known as transient voltage suppression diodes, are electronic components that protect against transient over-voltage, which can be caused by factors such as lightning, electrostatic discharge, and electrical surges. The SM15T10CAY TVS diode is designed to provide protection from destructive voltage transients for a wide range of voltage inputs. In this article, we will take a closer look at the SM15T10CAY and its application field and working principle.

Applications of the SM15T10CAY TVS Diode

The SM15T10CAY TVS diode is highly popular for use in computers, machines, control systems, and digital products. It can be used for direct protection of computer I/O ports, including serial ports and USB ports. The device is also suitable for the protection of power supplies, internal wiring, and external wiring. Additionally, the SM15T10CAY TVS diode is suitable for protecting ac power lines, dc power lines, telephone lines, and various DC circuits.

Working Principle of the SM15T10CAY TVS Diode

The working principle of the SM15T10CAY TVS diode is based around the avalanche breakdown voltage principle, wherein an excess amount of voltage is applied to a semiconductor diode, resulting in suddenly increased electrical current. The increased current results in the production of a huge amount of heat that momentarily causes a change in the electric properties of the diode. This sudden change in electric properties of the diode at the avalanche breakdown voltage helps protect the connected circuit against overvoltage and surges.

The SM15T10CAY TVS diode also includes a Zener diode layer with a high breakdown voltage of around 93V and a peak pulse power rating of up to 15 kW. The TVS diode can also provide electrical isolation up to 1500Vrms/minute. It is delivered in a SO-8-A package and is designed for direct mounting onto printed circuit boards.
