Abstract

A silicon controlled rectifier device including an SCR portion controlled by an input voltage signal to a voltage comparator and having a latching circuit to permit the SCR portion to remain in the conducting state once switched even in the absence of the input voltage signal. Such a device is especially useful when a narrow input voltage signal is used to switch the SC portion into its conducting state.
