Features
l The three layer, two terminal, axial lead, hermetically sealed
diacs are designed specifically for triggering thyristors.
• Lead Free Finish/Rohs Compliant (Note1) ("P"Suffix designates
Compliant. See ordering information)
• Moisture Sensitivity: Level 1 per J-STD-020C
l These diacs are intended for use in thyrisitors phase control ,
circuits for lamp dimming, universal motor speed control ,and
heat control. Type number is marked.
Maximum Ratings
l Operating Temperature: -40^oC to +110^oC
l Storage Temperature: -40^oC to +125^oC
