Description:
The
OP180
is a GaAs and the
OP280K, OP280KT
is a GaAIAs infrared LED mounted in plastic leadless PLCC-2 SMD
package with a flat lens window that allows a wide beam angle. The major differentiator from the two High power GaAlAs
LEDs is that
OP280KT
has reversed polarity terminals. The
OP280V
is incorporated into the group with a high performance
850nm invisible VCSEL (Class 1M) with silicon encapsulant. Its high speed, high output and narrow beam pattern (18°) makes
it very suitable for high-speed data equipment applications. The
OP280PS
has a GaAlAs diode in a PLCC-2 package that
features a narrow irradiance pattern. The PLCC-2 packaging is suitable for single device or array applications.
The 180 and 280 Series LEDs are mechanically and spectrally matched to OP580 series phototransistors.

Notes:
1. Solder time less than 5 seconds at temperature extreme.
2. Derate linearly at 2.17 mW/° C above 25° C.
3. E
E(APT)
is a measurement of the apertured radiant incidence upon a sensing area 0.081” (2.06 mm) in diameter, perpendicular to and
centered on the mechanical axis of the lens and 0.590” (14.99 mm) from the measurement surface. E
E(APT)
is not necessarily uniform within
the measured area.
