SM6T15CAY is an ultra-low capacitance transient voltage suppressor (TVS) produced by STMicroelectronics. It is available in an SMA package and has an exceptionally low leakage current. It is designed for applications that require high-level ESD protection, such as USB ports and audio-visual equipment. This TVS is capable of limiting the transient voltage up to 15V, with a peak pulse current up to 1.5A. The ultra-low capacitance ensures minimal interference to sensitive signals. The low leakage current maximizes the protection of sensitive electronic components from electrostatic discharge.
