OP240
OP245
Description:
Each device in this series is a high intensity gallium aluminum arsenide infrared emitting diode that is suited for use as a
PCBoard mounted slotted switch or an easy mount PCBoard interrupter.
Each dome lens
OP240
and
OP245
device is an 890 nm diode that is molded in an IR-transmissive clear epoxy side-looking
package.
OP240 is mechanically and spectrally matched to the OP550 and OP560 series of phototransistors. OP245 is
mechanically and spectrally matched to the OP555 and OP565 series devices.
Please refer to Application Bulletins 208 and 210 for additional design information and reliability (degradation) data.
Applications:
Space-limited applications
PCBoard mounted slotted switch
PCBoard interrupter

Notes:
1. RMA flux is recommended. Duration can be extended to 10 seconds maximum when flow soldering. A maximum of 20 grams force may be
applied to the leads when soldering.
2. Derate linearly 1.33 mW/° C above 25° C.
3. E
E(APT)
is a measurement of the average apertured radiant energy incident upon a sensing area 0.180” (4.57 mm) in diameter perpendicular to
and centered on the mechanical axis of the lens and 0.653” (6.60 mm) from the lens tip. E
E(APT)
is not necessarily uniform within the measured
area.
