TVS diode arrays prevent ESD damage to high-speed interfaces

TVS diode arrays prevent ESD damage to high-speed interfaces
Littelfuse has introduced two series of TVS diode arrays (SPA diodes) designed to safeguard many of the latest high-speed interfaces from damage due to ESD. The SP7538P series TVS diode arrays integrate eight channels of ultra-low capacitance rail-to-rail diodes and an additional Zener diode in a µDFN-9 package. The SP0544T series TVS diode arrays have a similar design but are smaller, with four channels of ultra-low capacitance rail-to-rail diodes instead of eight.
