ST Series Automotive TVS Diode ESD Suppressors

Eaton Electronics Automotive TVS Diode ESD Suppressors are AEC-Q101-qualified diodes ideal for automotive applications. The TVS diodes protect up to four I/O lines with unidirectional or bi-directional options. The diodes act as electrostatic discharge (ESD) suppressors and operate with ±8V to ±30V typical ESD ratings. The Eaton Electronics Automotive TVS Diode ESD Suppressors feature a low clamping voltage range and a wide junction capacitance range. The TVS diodes are RoHS compliant and ideal for automotive chassis and safety systems, advanced driver assistance systems (ADAS), communications/infotainment systems, powertrain control, and automotive lighting applications.
