RClamp3321P
Ultra-Low Capacitance
1-Line, 3.3V ESD protection
PROTECTION PRODUCTS - RailClamp
Description
Features
The RClamp®3321P 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 finished 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.
