Fairchild Semiconductor MOC3051M, MOC3052M Random-Phase Optoisolators Datasheet
This document is a datasheet for the Fairchild Semiconductor MOC3051M and MOC3052M, which are 6-Pin DIP Random-Phase Optoisolators and Triac Drivers. These devices feature an AlGaAs infrared emitting diode optically coupled to a non-zero-crossing silicon bilateral AC switch (triac). They are designed to provide random phase control of high current triacs or thyristors, isolating low voltage logic from 115 and 240 Vac lines.

What is the maximum isolation voltage for the MOC3051-M/MOC3052-M?
The devices are rated for a minimum isolation voltage of 7500 V peak.
What continuous forward current can the emitter handle?
The emitter can handle a continuous forward current of up to 60 mA.
What is the maximum isolation voltage of the MOC3051-M/MOC3052-M?
The device is rated for a maximum isolation voltage of 7500 Vac peak.
How is the current‑limiting resistor value calculated for a line voltage?
The resistor must limit the driver current to 1 A, so R = Vp AC / 1 A (peak line voltage divided by 1 A).
