WebbModes Ι– and ΙΙΙ+ are, however, less sensitive configurations requiring a greater gate current to cause triggering than the more common triac triggering modes of Ι+ and ΙΙΙ–. Also, just like silicon controlled rectifiers (SCR’s), triac’s also require a minimum holding current I H to maintain conduction at the waveforms cross over point.
