Description
RClamp®03371P is an ultra low capacitance ESD
protection device specifically designed to protect highspeed
Ethernet lines. It offers desirable characteristics
for board level protection including fast response time,
low operating and clamping voltage, and no device
degradation. The device features high surge capability
of 6A (tp = 8/20 μs). RClamp03371P has a typical
capacitance of only 0.23pF, which is ideal for high speed
lines. Each device will protect one high-speed data line
operating up to 3.3 volts.
RClamp03371P is in a DFN 1.0 x 0.6 x 0.55mm 2-Lead
package. This ultra small package design simplifies
PCB layout and facilitates matching trace lengths for
consistent impedance between high speed differential
lines. The combination of small size, low capacitance, and
high ESD surge capability makes them ideal for use in
industrial and consumer applications.
