Description

RClamp®3552TQ is a low voltage RailClamp which can

provide ESD protection to IEC 61000-4-2 on highspeed

ports. It is manufactured using Semtech’s proprietary

low voltage technology, designed to minimize both the

ESD peak clamping and TLP clampingvoltage. These

devices “snap-back” to a low on-state voltage when the

breakdown voltage of the device is exceeded. This has

the advantage of lowering the overall ESD clamping

voltage. When the device is in the on-state, the dynamic

resistance is typically 0.30 Ohms, further minimizing

the ESD clamping. Maximum capacitance is only 0.40pF

allowing the RClamp3552TQ to be used in applications

operating in excess of 6GHz without appreciable signal

attenuation. Each device will protect two lines operating

at 3.5 volts.

RClamp3552TQ is in a 3-pin SLP1006N3T package. It

measures 1.0 x 0.6 mm with a nominal height of only

0.4mm. The leads are finished with lead-free NiPdAu.

The combination of low peak ESD clamping, low

dynamic resistance, and low capacitance makes this

device suitable for applications such as USB 3.0, LVDS,

audio, and V-By-One interfaces.
