MOC3051SR2-M

Manufacturer Part Number
MOC3051SR2-M
Description
MOC3051SR2-M6-PIN DIP RANDOM-PHASE OPTOISOLATORS TRIAC DRIVERS (600 VOLT PEAK)
Manufacturer
Fairchild Semiconductor
Datasheet
DESCRIPTION
The MOC3051-M and MOC3052-M consist of a AlGaAs infrared emitting diode optically coupled to a non-zero-crossing silicon
bilateral AC switch (triac). These devices isolate low voltage logic from 115 and 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 perfor-
mance of inductive loads.
FEATURES
• Excellent I
• High isolation voltage—minimum 7500 peak VAC
• Underwriters Laboratory (UL) recognized—File #E90700
• 600V peak blocking voltage
• VDE recognized (File #94766)
APPLICATIONS
• Solenoid/valve controls
• Lamp ballasts
• Static AC power switch
• Interfacing microprocessors to 115 and 240 Vac peripherals
• Solid state relay
• Incandescent lamp dimmers
• Temperature controls
• Motor controls

Fairchild Semiconductor Corporation OPTOISOLATORS TRIAC DRIVERS Minimum LED Off Time in Phase Control Applications AC SINE In Phase control applications one intends to be able to control each AC sine half wave from 0 to 180 degrees. Turn on at zero degrees means full power and turn on at 180 degree means zero power. This is not quite possible in reality because triac driver and triac have a fi ...

Figure 9 shows that the delay time depends on the LED trigger current, while the actual trigger transition time t(f) stays constant with about one micro second ...
