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
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: -40oC to +125oC l Storage Temperature: -40oC to +125oC l Thermal Resistance Junction to Lead:167oC/W l Thermal Resistance Junction to Ambient: 400oC/W
