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 con-
nected to the Power triac and carries the highest amount of
thermal energy. For loads which approach the maximum cur-
rent 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 clear-
ance 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 re-
quirement. 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 sup-
ply line applications.
