PROTECTION PRODUCTS
Description
RClamp®2594N is specifically designed to provide
secondary surge and ESD protection on high-speed
ports. RClamp2594N integrates low capacitance, surge-
rated steering diodes with a high power transient
voltage suppressor (TVS). The TVS utilizes snap-back
or “crow-bar” technology to minimize device clamping
voltage and features high surge current capability of 35A
(tp=8/20us). ESD characteristics are highlighted by high
ESD withstand voltage (+/-30kV per IEC 61000-4-2) and
extremely low dynamic resistance (0.05 Ohms typical).
Each device will protect four lines operating at 5 volts.
RClamp2594N is in a 10-pin SLF3020P10T package. It
measures 3.0 x 2.0 mm with a nominal height of only
0.4mm. The leads are finished with lead-free matte Sn
plate.
