Plastic Point Source Infrared Emitting Diode OP245PS Features: x Point source irradiance pattern x Side-looking package for space-limited applications x Wavelength matched to silicon’s peak response x Higher power output than GaAs at equivalent drive currents x Fast switching speed Description: Each OP245PS device is an infrared emitting diode with a 850 nm GaAIAs chip, molded in a clear IR-transmissive side-looking epoxy package. This package makes these devices ideal for PCBoard mounted slotted switches and for mounted interrupt detectors. The stable forward VF vs TA characteristic make them suitable for applications that have limited voltage, such as battery operation; whereas, the low TR/TF makes them ideal for high-speed operations. Please refer to Application Bulletins 208 and 210 for additional design information and reliability (degradation) data. Applications: x Space-limited applications x PCBoard mounted slotted switch x Mounted interrupt detector x High-speed applications Ordering Information Part Number LED Peak Wavelength Lens Type Total Beam Angle Lead Length (min.)

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. EE(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” (16.6 mm) from the lens tip. EE(APT) is not necessarily uniform within the measured area. OPTEK reserves the right to make changes at any time in order to improve design and to supply the best product possible.
