描述 Description

RClamp1221H-RClamp3621H series is a low capacitance

ESD protection device specifically designed to protect highspeed

Ethernet lines. They offer desirable characteristics

for board-level protection, including fast response time,

low operating and clamping voltage, and no device

degradation. These devices feature a large cross-sectional

area for conducting high surge capability of 15A-35A (tp

= 8/20 μs). RClamp1221H-RClamp3621H has a typical

capacitance of only 1.7pF and 1.8pF, which is ideal for

high-speed lines. Each device will protect one high-speed

data line.

RClamp1221H-RClamp3621H series is in a 2-pin SOD-323

package; leads are finished with lead-free Matte tin. They

may be used to protect 12V, 15V, 24V, and 36V systems.

The combination of small size, low capacitance, and high

ESD surge capability makes them ideal for use in industrial

and telecom applications.
