Feb ru ary 2000
NPN Phototransistor with Collector-Emitter Capacitor
Types OP770A, OP770B, OP770C, OP770D
Features
Supresses high frequency noise
Variety of sensitivity ranges
Wide receiving angle
Side looking package for space limited
applications
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.

Notes:
(1) RMA flux is rec om mended. 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 lense surface of the
phototransistor being tested.
(4) To calculate typical collector dark current in µA, use the formula ICED = 10 (0.040TA-3.4) when
TA is ambient temperature in °C.
Typi cal Per form ance Curves
The device’s wide receiving angle
provides relatively even reception over a
large area.
Typical Spectral Response
Schematic
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.
