STMicroelectronics ESDA6V1-5SC6Y, Quint-Element Uni-Directional TVS Diode, 80W, 6-Pin SOT-23

ST's automotive dataline ESD protection devices are monolithic transient voltage suppressors or application-specific discrete devices that guard against surges and against ESD. They protect components connected to data and transmission lines in applications such as automotive infotainment, navigation, communication and audio and video systems. Look for the Y extension in the part number for the automotive version of the given protection device

They offer:
Standard CANbus, LINbus, and FLEXray automotive interfaces
Flexibility in packaging and integration options
ST’s advanced expertise in ESD protection for communication systems such as audio/visual and infotainment applications

This device is a monolithic voltage suppressor designed to protect components connected to data and transmission lines against ESD. It clamps the voltage just above the logic level supply for positive transients, and to a diode drop below ground for negative transients
