ABSTRACT:
A simplified solid state transient voltage and overcurrent protector for telecommunications equipment providing uniform protection characteristics between telephone lines and between either line and ground is shown in which two symmetrical thyristor chips are mounted with their normal common layer connected together on an enlarged heat sink. The assembly, together with current limiting PTC elements is encapsulated to form a dual-in-line package.
