Semtech RClamp0512TQ


RClamp®0512TQ is specifically designed to provide secondary surge and ESD protection on high-speed ports. RClamp0512TQ 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 20A (tp=8/20us). ESD characteristics are highlighted by high ESD withstand voltage (+/-30kV per IEC 61000-4-2) and extremely low dynamic resistance (0.075 Ohms typical). Each device will protect two lines operating at 5 volts and are qualified to AEC-Q100, Grade 1 (-40 to +125 oC) for automotive applications.
