LCP1521SRL ST Transient Voltage Suppressors (TVS)

The LCP1521SRL is a line current protector (LCP) from STMicroelectronics, designed for telecommunication line protection against overcurrents and overvoltages. For selection, verify holding current rating, switching voltage, surge capability, and operating temperature suitable for telecom applications. Features include bidirectional protection for AC or bipolar signal lines, low leakage current for minimal signal distortion, and compliance with ITU-T K.20/K.21 telecom surge protection standards. Ideal for telecommunications line protection (modems, SLICs, xDSL), set-top boxes, answering machines, fax machines, and any telecom equipment requiring robust overcurrent and overvoltage protection with low capacitance to preserve signal quality.
