A 500V monolithic bidirectional 2×2 crosspoint array

This paper will report on a high voltage IC employing a gated diode switch replacing metallic switches normally used for the concentrator function that meets the telephone loop switch requirements, which are voltage blocking to +500V, surge conduction to 1A levels and interruption of direct currents forced by the 48V dc normally used to power telephone loops.
