• 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
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.
