OP245PS

Plastic Point Source Infrared Emitting Diode OP245PS Features: x x x x x Point source irradiance pattern Side-looking package for space-limited applications W avelength matched to silicon’s peak response Higher power output than GaAs at equivalent drive currents 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 OP245PS LED Peak Wavelength 850 nm Lens Type Flat Total Beam Angle ±18° Lead Length (min.) 0.5” / 12.7 mm 1 2 Pin # NOTES; 1. OUTSIDE DISCRETE SHELL IS POLYSULFONE P1700-11 CLEAR. 2. THIS LED IS BUILT WITH A 0.011” X 0.011” GaAIAs CHIP. 3. MAX ALLOWABLE EPOXY MENSCUS IS 0.010”. 1 ANODE 2 CATHODE [MILLIMETERS] INCHES LED Anode Cathode 1 2 DIMENSIONS ARE IN: To avoid stress cracking, we suggest using ND Industries’ Vibra-Tite for thread-locking. Vibra-Tite evaporates fast without causing structural failure in OPTEK' molded plastics.

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.
