SEMTECH TCLAMP1202P.TGT

TClamp 1202P provides dedicated surge and ESD protection for RS-485 and other 12V lines in industrial applications. It features high surge current capability of 100A (tp = 8/20μs) and low clamping voltage making them ideal for use in harsh transient environments. This device is designed to replace mulitple discrete components by integrating low capacitance, surgerated compensation diodes with a high power transient voltage suppressor (TVS). Capacitance is limited to 12pF maximum to ensure correct signal transmission on high-speed lines. Each TClamp1202P may be used to protect up to two lines. A voltage bus operating up to 12V can also be optionally protected. The TClamp1202P is in a 5-pin SLP2020P5 package, measuring 2.0×2.0mm with a nominal height of 0.60mm. The fow- through package design simplifes PCB layout.
