Random Phase Control: These optocouplers allow the triac to be triggered at any point in the AC cycle. This is different from zero-crossing optocouplers, which only trigger the triac when the AC voltage is near zero volts.High Off-State Voltage: They can block off-state voltages of up to 600V.Optically Isolated: They utilize a Gallium Arsenide (GaAs) infrared emitting diode (LED) optically coupled to a silicon bilateral AC switch (triac), ensuring electrical isolation between the low-voltage control circuit and the high-voltage AC load.Enhanced dv/dt Capability: They feature enhanced static dv/dt capability, which is crucial for stable switching performance, especially when handling inductive loads, where rapid voltage changes can occur.6-Pin DIP Package: They are housed in a standard 6-pin DIP for through-hole mounting.Low Input Trigger Current: The MOC3051 has a maximum trigger current of 15mA, while the MOC3051M has a maximum trigger current of 15mA.High Isolation Voltage: They offer high isolation voltage (4170 Vrms or 7500 Vpk depending on the specific variant) between the input and output, ensuring safety and electrical separation.Wide Operating Temperature Range: They operate reliably across a wide temperature range, typically -40°C to +85°C.
