It features a high maximum ESD withstand voltage of ±17kV contact and ±20kV air discharge per IEC 61000-4-2. RClamp3346P is designed to minimize both the ESD peak clamping and the TLP clamping. Package inductance is reduced at each pin resulting in lower peak ESD clamping voltage. The dynamic resistance is among the industry’s lowest at 0.15 Ohms (typical). Maximum capacitance on each line to ground is 0.65pF allowing the RClamp3346P to be used in applications operating in excess of 5GHz without signal attenuation. Each device will protect up to six lines (three high-speed pairs). The RClamp3346P is in a 7-pin SGP2708N7 package measuring 2.7 x 0.8mm with a nominal height of 0.50mm. The leads have a nominal pin-to-pin pitch of 0.40mm. Flow- through package design simplifies PCB layout and maintains signal integrity on high-speed lines. The combination of low peak ESD clamping, low dynamic resistance, and innovative package design enables this device to provide the highest level of ESD protection for applications such as USB 3.0, eSATA, and DisplayPort. 2.70 0.50 0.80
