Description
These optocouplers consist of two gallium-arsenide light-emitting diodes connected in a
reverse-parallel configuration for ac-input applications and a silicon n-p-n phototransistors
mounted for each channel in standard 4, 8 and 16-pin dual-in-line packages.
Absolute Maximum Ratings (TAMB = 25°C u.o.s.)
Input-to-Output Isolation Voltage (note 1) ±5000 Vdc
Collector-Emitter Voltage (note 2) 35 V
Emitter-Collector Voltage 7 V
Input Diode Continuous Forward Current (TA ≤ 25°C) (note 3) ±50 mA
Continuous Power Dissipation (TA ≤ 25°C)
PhotoTransistor 150 mW
Input Diode + Phototransistor per Channel (note 5) 200 mW
Storage Temperature Range -55°C to 125°C
Lead Temperature 1.6 mm from case, 10 secs 260°C
Notes
1. This rating applies for sine-wave operation at 50 or 60 Hz.
2. This value applies when the base-emitter diode is open-circuited.
3. Derate linearly to 100°C free-air temperature at 0.67 mA/°C
4. Derate linearly to 100°C free-air temperature at 2 mW/°C
5. Derate linearly to 100°C free-air temperature at 2.67 mW/°C

Notes
6. These parameters are measured between all input-diode leads shorted together and all phototransistor leads
shorted together.
7. The higher of the two values of IC(ON) generated by the two diodes is taken as IC(ON)1.
8. These parameters apply to either direction of the input current.
