High Speed, High Power, Hermetic Infrared Emitting Diode OP224K Features: • • • • • Hermetically sealed package Mechanically and spectrally matched to other OPTEK devices Designed for direct mount to PCBoard High Modulation Bandwidth High Irradiance Power Description: The OP224K device is an 875 nm gallium aluminum arsenide infrared emitting diode (GaAIAs), mounted in a hermetically sealed “pill” package with an enhanced temperature range and a narrow irradiance pattern that provides high on-axis intensity for excellent coupling efficiency. These devices offer significantly higher power output than GaAs at equivalent drive currents and have a wavelength that is matched to silicon’s peak response. Their small package size permits high device density mounting. All these LEDs are mechanically and spectrally matched to the OP300 series, OP600 series and OP640 series devices. Please refer to Application Bulletins 208 and 210 for additional design information and reliability (degradation) data, and to Application Bulletin 202 for pill-type soldering to PCBoard.

Refer to Application Bulletin 202 which reviews proper soldering techniques for pill-type devices. 2. No clean or low solids. RMA flux is recommended. Duration can be extended to 10 seconds maximum when flow soldering. 3. Derate linearly 1.50 mW/° C above 25° C. 4. EE(APT) is a measurement using a 0.031” (0.787 mm) diameter apertured sensor placed 0.50” (12.7 mm) from the measuring surface. EE(APT) is not necessarily uniform within the measured area.
