NPN Silicon Phototransistors
OP515A, OP515B, OP515C, OP515D
Notes:
(1) E
e(APT)
is a measurement of the average apertured radiant energy incident upon a sensing area 0.250” (6.35mm) in diameter and
perpendicular to and centered to the mechanical axis of the emitting surface at a distance of 0.466” (11.84mm). E
e(APT)
is not nec-
essarily uniform within the measured area.
(2) Derating Linearly 0.71 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 nA, use the formula I
CED
= 10
(0.040T
A
-3.4)
where T
A
is ambient temperature in °C.
