Product details

Four-channel rail-to-rail clamp for USB 2.0 ports

The Texas Instruments TPD4EUSB30DQAR is a four-channel steering (rail-to-rail) ESD protection diode array. Each of the four unidirectional channels shunts ESD current to the supply or ground rail. The reverse standoff voltage is rated at 5.5 V max.

45 W peak pulse — what it clears

10-USON footprint and assembly

The 10-USON (2.5x1.0 mm) package uses a 0.50 mm pitch with no exposed leads — the terminations are flush with the package body. The land pattern requires a solder paste stencil aperture that matches the pad geometry exactly; a 0.125 mm stencil thickness is typical for this pitch.
