Du ra tion can be ex tended to 10 sec. max. when flow sol der ing. Max. 20 grams force may be applied to leads when soldering. (2) Derate linearly 1.33 mW/° C above 25° C. (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 lens 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) where TA is ambient temperature in ° C. 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.
