(3) Light source is an unfiltered GaAs LED with a peak emission wavelength of 935 nm and a radiometric intensity level which varies less than 10% over the entire lense surface of the phototransistor being tested. (4) To calculate typical collector dark current in µA, use the formula ICED = 10 (0.040T A-3.4) when TA is ambient temperature in °C. Description The OP770 consists of an NPN phototransistor and 1000 pF capacitor molded in a clear 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 OP770 is 100% production tested using an infrared light source for close correlation with Optek’s GaAs and GaAIAs emitters. Side-looking package is designed for easy PC board mounting of slotted optical switches or optical interrupt detectors.
