• Manufacturer Part Number: MOC2A6010
• Description: OPTOISOLATOR 2 AMP ZERO CROSS TRIAC OUTPUT 600 VOLTS
• Manufacturer: MOTOROLA [Motorola, Inc]

Terms in the model signify:
T A = Ambient temperature
T S = Optional additional
T S =
T C = Case temperature
T J = Junction temperature
P D = Power dissipation
Values for thermal resistance components are: R CA = 36 C/W/in maximum
Values for thermal resistance components are:
The design of any additional heatsink will determine the values of R SA and R CS .
T C – T A = P D (R CA )
T C – T A
Use care to maintain the minimum spacings as shown.
Safety and regulatory requirements dictate a minimum
of 8.0 mm between the closest points between input
and output conducting paths, Pins 3 and 7. Also, 0.070
inches distance is required between the two output
Pins, 7 and 9.
Keep pad sizes on Pins 7 and 9 as large as possible
for optimal performance.
Each device, when installed in the circuit shown
in Figure 14, shall be capable of passing the fol-
lowing conducted noise tests:
