The RCLAMP3321P provides ESD protection for USB3.0,

HDMI1.3/1.4, and other high-speed ports. It may be used

to meet the ESD immunity requirements of IEC 61000-4-2. The

RCLAMP3321P is designed to minimize both the ESD peak

clamping and the TLP clamping. The dynamic resistance is minimized

(0.47 Ohms typical) for optimum protection of sensitive

circuits. Maximum ca-pacitance is only 0.35pF. This allows the

RClamp3321P to be used in applications operating in excess of

5GHz without signal attenuation. These devices are manufac-tured

using Semtech’s proprietary low voltage technol-ogy for superior

characteritics at operating voltages up to 3.3 volts.

The RClamp3321P is in a 2-pin SLP1006P2 package. It

measures 1.0 x 0.6 x 0.5mm. The leads are spaced at a pitch of

0.65mm and are fi nished with lead-free NiPdAu. Each device will

protect one line operating at 3.3 volts. The combination of low

peak ESD clamping, low dynamic resistance, and low

capacitance makes this device suit-able for applications such as

USB 3.0, HDMI and V-By-One interfaces in portable devices.
