Thermal measurements of R

JC
are referenced to the point on
the heat tab indicated with an
‘X’. Measurements should be
taken with device orientated
along its vertical axis.
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:
IEEE 472 (2.5 KV)
Lamp Dimmer (NEMA Part DC33, 3.4.2.1)
NEMA ICS 2–230.45 Showering Arc
