TLPxxM/G/G-1 PowerSO-10TM TLPxxM is a tripolar transient surge arrestor for telecom line.
The TLPxxM/G/G-1 series are tripolar transient surge arrestors designed for primary and secondary protection of sensitive telecom equipment such as line cards, distribution frames and terminal equipment. They feature a crowbar protection scheme, low capacitance (110 pF typ.) and very low leakage current (5 pA max), ensuring reliable operation without aging or noise.
The document lists electrical characteristics (peak pulse current up to 100 A, holding current 150 mA), thermal resistance (1.0 °C/W junction‑to‑case), mechanical dimensions for various package types (PowerSO‑10, DPAK, PAK) and test procedures for functional holding current. It also includes thermal management guidance for surface‑mount implementations using IMS substrates.
