Infrared Light Emitting Diode
OP180 & OP280 Series
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 LED s are mechanically and spectrally matched to OP580 series phototransistors.
Features:
• High power GaAs—OP180, 940 nm center wavelength
• High power GaAIAs—OP280K and OP280KT, 875 nm center wavelength
• VCSEL GaAlAs-OP280V, 850 nm center wavelength
• Point Source GaAlAs-OP280PS, 850 nm center wavelength
• PLCC-2 package style with silicon encapsulation
• Half Power Beam angle from 18° to 100°
• Suitable for single device or array applications

Notes:
1. Solder time less than 5 seconds at temperature extreme.
2. Derate linearly at 2.17 mW/° C above 25° C.
3. EE(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. EE(APT) is not necessarily uniform within
the measured area.
