Note: Drawing not to scale

The SP3145 represents an industry first: unidirectional

ESD protection in a 01005 type package. Unidirectional

protection should be favored over bi directional

performance, particularly on logic and data lines, which

typically do not transit zero volts during standard

operation. Fast-acting, semiconductor based technology

can withstand multiple ESD events, without wear-out or

degradation. Low nominal capacitance makes this product

meaningful for interfaces running at high data rates,

approaching 5 GHz clock speeds.
