Description
This thermal model assumes that a 16-pin dual-channel
(SOIC-16) optocoupler is soldered into an 8.5 cm x 8.1
cm printed circuit board (PCB). These optocouplers are
hybrid devices with four die: two LEDs and two detec-
tors. The temperature at the LED and the detector of the
optocoupler can be calculated by using the equations
below.
