The TLPxxM/G/G-1 series are tripolar transient surge arrestors used for primary and secondary protection in sensitive telecom equipment. They feature tripolar crowbar protection, voltage range selected for telecom applications, repetitive peak pulse current, holding current, low capacitance, and low leakage current.
The TLPxxM/G/G-1 series are tripolar transient surge arrestors designed for primary and secondary protection of sensitive telecom equipment, such as analog and ISDN line cards and distribution frames. They offer a crowbar protection mode, low leakage and low capacitance, and remain short‑circuited when destroyed to maintain protection.
This manual details the electrical characteristics, thermal resistance, mechanical dimensions, marking codes, and recommended mounting techniques for the PowerSO‑10, DPAK and ITPAK packages. It also includes functional holding‑current test procedures and thermal‑management recommendations for various PCB substrates.
