Thermal Model
(Discussion applies to ACPL-3130, ACPL-J313 and ACNW3130)
The steady state thermal model for the ACPL-3130 is
shown in Figure 32. The thermal resistance values given
in this model can be used to calculate the temperatures
at each node for a given operating condition. As shown
by the model, all heat generated flows through q
raises the case temperature T
q
therefore, determined by the designer. The value of q
83°C/W was obtained from thermal measurements using a
2.5 x 2.5 inch PC board, with small traces (no ground plane),
a single ACPL-3130 soldered into the center of the board
and still air. The absolute maximum power dissipation
derating specifications assume a q
From the thermal mode in Figure 32 the LED and detector
IC junction temperatures can be expressed as:
