RCLAMP3321P
Description
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 mi-
nimized (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-tu-
red using Semtech’s proprietary low voltage technol-ogy for su-
perior characteritics at operating voltages up to 3.3 volts.

USB 3.0
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
