The MOC3071M, MOC3072M and MOC3073M consist of a GaAs infrared emitting diode optically coupled to a non-zero- crossing silicon bilateral AC switch (triac). These devices isolate low voltage logic from 240 VAC lines to provide random phase control of high current triacs or thyristors. These devices feature greatly enhanced static dv/dt capability to ensure stable switching performance of inductive loads.

• Excellent IFT Stability—IR Emitting Diode Has Low Degradation
• 800 V Peak Blocking Voltage
• Safety and Regulatory Approvals– UL1577, 4,170 VACRMS for 1 Minute– DIN EN/IEC60747-5-5 (pending approval)
