Abstract
A snubber circuit for use with hold circuits employed in telecommunication applications that employ an SCR as the principle control device. The included circuit prevents false hold turn on in response to static discharge. Voice band impedance and ringing signals are not adversely affected by the addition of the circuit to a standard SCR type hold circuit.
