The TPA series are TRISIL devices, specially designed for protecting sensitive telecommunications equipment against lightning and transient voltages induced by AC power lines. They are available in the F126 axial package. TRISIL devices provide bidirectional protection by crowbar action. Their characteristic response to transient overvoltages makes them particularly suited to protect voltage sensitive telecommunications equipment.
The TPA series are TRISIL devices specifically designed to protect sensitive telecommunication equipment against lightning and transient voltages induced by AC power lines. These devices provide bidirectional protection via a crowbar action mechanism and are available in the F126 axial package.
The document details absolute maximum ratings, electrical characteristics for various voltage types (from 62V to 270V), thermal resistances, and compliance with international standards such as CCITT ITU-K20, VDE0433, IEC-1000-4-5, FCC Part 68, and BELLCORE TR-NWT-001089. It also includes test circuit diagrams for verifying holding current and surge parameters.
