TVS - DiodesA TVS diode (Transient Voltage Suppression diode, also known as a thyrector) is a form of p-n junction diode designed to protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage moments, which are referred to as Electrostatic Discharge (ESD). TVS diodes have several advantages over other protective devices such as Gas Discharge Tubes (GDTs)...they are able to respond in milliseconds, they move more power than other types of protection, and can handle more voltage than GDTs.The TPC27AHM3_A/H is an example of a TVS diode, particularly designed with the automotive industry in mind. This device is designed for transient voltage suppression of automotive functional loads in applications from 5V up to 42V with an environmental temperature range of -40°C to +125°C. This device is compliant with automotive standards such as AEC-Q101 and is aware of both positive and negative transient loads up to 600 watts.The TPC27AHM3_A/H is designed to provide highly reliable surge protection; it has a low turn-ON voltage between 4.6V and 6.5V and a fast turn-ON time of less than 5µs. This device is designed to divert high surge currents, preventing any damage to sensitive circuits and allowing the automotive load, or functional load, to stay within its operating window.The working principle of a TVS diode is simple; it uses a P-N junction device, like a standard diode, to provide a low voltage drop and to quickly and efficiently redirect the surge current away from the protected load. As soon as the protection device sees the surge current, it turns on by changing its internal structure. When the surge voltage and the current decrease, the protection device is turned off by restoring its internal structure and allowing the current and voltage to return to their normal levels. This fast and reliable response time is possible because of the materials used in the protection device; when an overvoltage occurs, it cut off new electron–hole pairs’ recombination and formed a strong space charge layer in front of the built-in field screening the external stimulating source to achieve the protection function.The TPC27AHM3_A/H has several benefits over other protection devices; its low turn-ON and turn-OFF voltage and fast response time make it well suited for automotive functional loads, where the current can spike rapidly and its fast response is very beneficial. It is designed to offer a low voltage drop, making it an ideal choice for sensitive circuits, as it allows them to stay within their operating window.Overall, the TPC27AHM3_A/H is a reliable and cost effective protected device, designed for applications where current can spike rapidly but must be kept within the standard operating windows. Its high response time and low voltage drop make it an ideal choice for automotive functional loads.
