APPLICATION CONSIDERATIONS
Input Drive Circuit
The MOCZ500 SSR is guaranteed to trigger with an input
current of 10 mA at 25°C. This trigger current increases with
lower ambient temperatures as shown on Figure 3 Forward
Trigger Current (IFT) versus Ambient Temperature.
When the input drive circuit is capable to supply the
MOCZ500 input LED trigger current, only a current limiting
resistor in series with the LED is required. TTL, DTL and
microcontrollers with enhanced current capability output
ports are able to meet this requirement.
Most CMOS logic circuits and Microcontroller output
ports are not rated to sink or source currents required to
trigger the MOCZ500. In this case a drive circuit is required
as shown in Figure 10 or a TTL buffer interface circuit as
shown in Figure 9.

Figure 9. Input Drive Circuit
Snubber Circuit
Snubberless operation of resistive loads is possible, but
snubbers are recommended for all applications. A typical application is shown in Figure 11. The snubber attenuates the
high kickback voltages and commutating dv/dt generated by
inductive loads during the turn off of the SSR. It also protects
the SSR from line transients generated elsewhere within the
equipment (for example inductive loads switched by mechanical contacts such as relays manual on/off switches etc.)
or outside the equipment such as air conditioners, electrical
heaters and motors.

Motorola Optoelectronics Device Data
MOCZ500
Snubbers are also necessary to pass noise immunity tests
such as IEC1000 4–4 for fast transients. In this test fast rising
high voltage spikes are superimposed onto the line voltage
to simulate AC line transients.
Switching Loads with Currents Below the Minimum
Current Rating
The MOCZ500 is capable to switch any inductive or resistive load within its rating of minimum 30 mA and a maximum
of 500 mA RMS.
At operating currents below the minimum specified value
the Power triac remains in the off state and the triac driver
carries the current. This may cause a problem, because the
triac driver has a significant lower commutating dv/dt than
the power triac. For loads below 30 mA AC rms a snubber is
mandatory. Evaluations with various low current inductive
and resistive loads concluded that a snubber of R = 100 Ω
and C = 10 nF is sufficient.

Thermal Considerations
Heat generated inside the MOCZ500’s power triac is
transferred through the leads to the circuit board where it is
dissipated. It is therefore important to solder all leads to the
circuit board. Pin 4 is thermally and electrically direct connected to the Power triac and carries the highest amount of
thermal energy. For loads which approach the maximum current rating of the SSR it is advisable to layout the pad size for
pin 4 as large as possible. See Figure 12 which considers
thermal and Regulatory requirements on a PCB.
Regulatory Safety Considerations
The MOCZ500 is designed to meet the National and
International Regulatory requirements for safe isolation
between input and output and functional isolation creepage
and clearance distances between the AC output pins.
Many equipment standards demand a creepage and clearance distance between input and output circuit of 8mm and a
thickness through insulation of 0.4mm (16 mil). All Motorola
Optocouplers do meet the thickness through insulation requirement. Product with lead bend option “T” meets the
creepage path requirement. The most stringent requirement
for creepage and clearance between the AC output pins is
3.5mm. Figure 12 shows a PCB pattern layout which meets
the regulatory requirements for 115 Vrms and 240 Vrms supply line applications.
