The SMP50-xxx series is a bidirectional crowbar protection device designed to protect telecommunication equipment against lightning and transient induced by AC power lines. It features a voltage range from 62V to 270V, low capacitance from 15pF to 30pF (typ.@ 50V), low leakage current (IR = 2µA max.), holding current (IH = 150mA min.), and repetitive peak pulse current (IPP = 50A).
The SMP50-xxx series is a component designed to protect telecommunication equipment, such as line cards and central office equipment, against lightning and transients induced by AC power lines. These Trisil™ devices utilize the SMA package (JEDEC DO-214AC) optimized for die size ratio.
