Features
l The three layer, two terminal, axial lead, hermetically sealed
diacs are designed specifically for triggering thyristors.
l These diacs are intended for use in thyrisitors phase control ,
circuits for lamp dimming, universal motor speed control ,and
heat control.
Maximum Ratings
l Operating Temperature: -40oC to +110oC
l Storage Temperature: -40oC to +125oC
