This device greatly reduces the snap-on effects that are present in symmetrical trigger circuits and mini- mizes control circuit hysteresis. This performance is possible with a AR .2yt single RC time constant, whereas a symmetrical circuit of comparable performance would require at least three additional passive components.

Zero voltage crossing is sensed via the base emitter diode drop of the 2N3859 which then allows the 4N40 SCR portion to be triggered and apply gate signal to the SC151 triac. The transient immunity is designed in through use of the GE-MOV, the snubber network and the choice of 400 volt semiconductors.
