SMP75-8

® SMP75-8 TRISILTM FEATURES Bidirectional surge arrestor. Very low stand-off voltage : VRM = 8 V. High repetitive surge capability : IPP = 75 A (10/1000µs). Very low capacitance : C < 75 pF Low leakage current : < 2 µA DESCRIPTION The SMP75-8 is a very low voltage transient surge arrestor especially designed to protect sensitive telecommunication equipment against lightning strikes and other transients. SMB (JEDEC DO-214AA) MAIN APPLICATION XDSL TRANSMISSION EQUIPMENT SCHEMATIC DIAGRAM BENEFITS Protection against high energy surges. Very low breakover voltage : VBO < 15 V, thus avoiding saturationof transformer. No signal distortion thanks to very low capacitance.
