Description The MOC3051M and MOC3052M devices consist of a GaAs infrared emitter diode that is optically coupled to a two-sided silicon alternating current switch (Triac) that does not cross with the zero point. These devices isolate the low-voltage logic of 115-VAC and 240-VAC lines to allow random phase control of high-current Triacs or thyristors. These devices feature greatly improved static dv/dt capability to ensure stable switching behaviour under inductive loads. Applications • Solenoid/valve controls • Lamp ballasts • Static AC power switch • Coupling of microprocessors to 115-VAC and 240-VAC peripherals • Semiconductor relays • Light bulb dimmer • Temperature controls • Motor controllers Features • Excellent low-degradation IFT stability IR emission diode • 600-V repetitive peak off-state voltage • Safety and official approvals - UL1577, 4.170 VACRMS for one minute - DIN EN/IEC60747-5-5 https://elecena.pl/product/27808564/moc3052sm-optocoupler-triac-600-v-100-ma-10-ma-7500-v-smd-6 2025-02-07 https://elecena.pl/product/27808564/moc3052sm-optocoupler-triac-600-v-100-ma-10-ma-7500-v-smd-6 2026-02-12
