Ambient Tempera- ture: Measured approximately 1.25 cm above the opto- coupler with no forced air. 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. 'T E1A = A 11 P E1 + A 12 P E2 +A 13 P D1 +A 14 P D2 'T E2A = A 21 P E1 + A 22 P E2 +A 23 P D1 +A 24 P D2 'T D1A = A 31 P E1 + A 32 P E2 +A 33 P D1 +A 34 P D2 'T D2A = A 41 P E1 + A 42 P E2 +A 43 P D1 +A 44 P D2 where: 'T E1A = Temperature difference between ambient and LED 1 'T E2A = Temperature difference between ambient and LED 2 'T D1A = Temperature difference between ambient and detector 1 'T D2A = Temperature difference between ambient and detector 2 P E1 = Power dissipation from LED 1; P E2 = Power dissipation from LED 2; P D1 = Power dissipation from detector 1; P D2 = Power dissipation from detector 2 A xy thermal coefficient (units in °C/W) is a function of thermal imped- ances T 1 through T 10 . |
