This package style is intended for direct mounting into PC boards. o Notes: (1) No-clean or low solids, RMA flux is recommended. Duration can be extended to 10 seconds max. when flow soldering. (2) Derate linearly 1.00 mW/o C above 25o C. (3) X defines the Testing Level per ESA/SCC 5000 Generic Specification Chart III. X will be either "B"(full processing) or "C"(reduced processing). N defines Lot Acceptance Tests per ESA/SCC Generic Specification 5000 Chart V. N will be either 1, 2, or 3. See Generic Processing Table for details. All devices are processed to Optek's 100 percent screening program patterned after ESA/SCC Generic Specification No. 5000. See page 13-4 for details. Part Number Guide OP224ESA-XN Optek High Reliability Part Number Gallium aluminum arsenide features twice the radiated output of gallium arsenide at the same forward current. With a wavelength centered at 890 nanometers, it closely matches the spectral response of silicon phototransistors, such as Optek's OP600 high reliability series. Optek Technology, Inc. o 1215 W.

(5) Ee(APT) is measured using a 0.031 inches (0.78 mm) diameter apertured sensor placed 0.50 inches (12.7 mm) from the mounting plane. (6) Ie is calculated from the measured value of Ee(APT) assuming the source to be located at the mounting plane. The conversion for this aperture and distance is Ie(mW/Sr) = Ee(APT)(mW/cm2) x 1.61. Optek reserves the right to make changes at any time in order to improve design and to supply the best possible product. Optek Technology, Inc. 1215 W.
