Description
The OP775 consists of an NPN
phototransistor and 1000 pF capacitor
molded in a blue tinted epoxy package.
The internal collector-emitter capacitor
allows the device to be used in
applications where external high
frequency emissions could compromise
signal integrity.
The device’s wide receiving angle
provides relatively even reception over a
large area.
The OP775 is 100% production tested
using an infrared light source for close
correlation with Optek’s GaAs and
GaAIAs emitters.
The side-looking package is designed for
easy PC board mounting of slotted
optical switches or optical interrupt
detectors.
