SMP100LC is a series of low capacitance transient surge arrestors designed by ST for the protec- tion of high debit rate communication equipment. Its low capacitance avoids any distortion of the sig- nal and is compatible with digital transmission line cards (xDSL, ISDN.).
The SMP100LC series are low‑capacitance transient surge arrestors (Trisil™) designed for protection of high‑speed communication equipment such as ADSL and ISDN lines. They offer bidirectional crowbar protection, a voltage range of 8 V to 400 V, and low leakage current, making them suitable for central‑office and subscriber‑side applications.
The document includes detailed electrical characteristics, thermal resistances, ordering codes, mechanical dimensions, test procedures, and compliance with standards such as GR‑1089, IEC‑61000‑4‑5, FCC Part 68, and VDE‑0433. It also provides packaging information (SMB, JEDEC DO‑214AA) and revision history.
