Low Capacitance RailClamp® 4-Line Surge and ESD Protection

Add to Watch List

RClamp® 0532T is a high performance TVS array designed to protect two differential lines from overvoltage events caused by ESD, lightning, CDE (Cable Discharge Events) and EFT (electrical fast transients). RClamp0532T features high surge current capability and may be used to protect Ethernet interfaces in MagJacks, communications equipment, security cameras, and industrial equipment.

RClamp0532T 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 10A (tp=8/20us). ESD characteristics are highlighted by high ESD withstand voltage (+/-30kV per IEC 61000-4-2) and extremely low dynamic resistance (0.020 Ohms typical). Each device will protect two lines operating at 5 volts.
