TVS Diode ESD Suppressors

Eaton Electronics TVS Diode ESD Suppressors provide a 3.3V to 70V reverse working range with a peak pulse current of up to 240A and capacitance as low as 0.07pF. These suppressors deliver highly reliable protection against fast and damaging voltage transients, such as electrostatic discharge, electrically fast transients, and induced lightning. The TVS diodes are offered in discrete and arrays and feature a fast response time, high-voltage withstand capability, long life, and low capacitance. These attributes make these diodes ideal for sensitive ICs with high-speed interfaces. Eaton TVS Diodes are designed for various consumer, computing, power systems, medical, and industrial applications.
