ON2179

The ON2179 is CNZ2179 is a reflective photosensor with a long focal distance, in which a high efficiency GaAs infrared light emitting diode is used as a light emitting element and a high sensitivity Si phototransistor is used as the light detecting element.

The features of ON2179 can be summarized as (1)long focal distance : 6 mm (typ.); (2)visible light cutoff resin is used.

The absolute maximum ratings of ON2179 are (1)input (light emitting diode) reverse voltage VR: 3 V/forward current IF: 50mA/power dissipation *1( input power derating ratio is 1.25mW/°C at Ta 25°C.) PD: 75mW; (2)output (photo transistor) collector-emitter voltage(base open) VCEO: 20 V/emitter-collector voltage(base open) VECO: 5V/collector current IC: 20 mA; (3)Collector power dissipation *2( output power derating ratio is 1.67mW/°C at Ta 25°C) PC: 100 mW; (4)temperature operating ambient temperature Topr: -25 to +80 °C/storage temperature T stg: -30 to +85°C.
