Transistor Output
These devices consist of a gallium arsenide infrared emitting diode optically coupled to a monolithic silicon phototransistor detector, in a surface mountable, small outline, plastic package. They are ideally suited for high density applications, and eliminate the need for through–the–board mounting.
· • Convenient Plastic SOIC–8 Surface Mountable Package Style
· • Closely Matched Current Transfer Ratios
· • Minimum V(BR)CEO of 70 Volts Guaranteed · • Standard SOIC–8 Footprint, with 0.050² Lead Spacing
· • Compatible with Dual Wave, Vapor Phase and IR Reflow Soldering
· • High Input–Output Isolation of 3000 Vac (rms) Guaranteed
· • UL Recognized

1. Input–Output Isolation Voltage, VISO, is an internal device dielectric breakdown rating. 2. For this test, pins 1 and 2 are common, and pins 5, 6 and 7 are common.
3. Refer to Quality and Reliability Section in Opto Data Book for information on test conditions.
4. Always design to the specified minimum/maximum electrical limits (where applicable).
5. Current Transfer Ratio (CTR) = IC/IF x 100%.
