| Vertical Cavity Surface Emitting Laser in Plastic Lateral Package Features * * * * 850nm VCSEL Technology High thermal stability Low drive current/high output intensity Plastic Lateral Flat convex lens for extra narrow beam angle. Description The OPV282 is a high performance 850nm VCSEL packaged for sensing applications. This product's combination of features including high speed, high output power and concentric beam makes it an ideal transmitter for integration into all types of position sensing equipment. Applications include: Absolute Maximum Ratings (TA = 25 C unless otherwise noted) Maximum Forward Peak Current Maximum Reverse Voltage Storage Temperature Operating Temperature Soldering Lead Temperature 30 mA 5 Volts -40 to +125C -40 to +85 C 260 C for 10 Seconds Photoelectric Sensors Light Curtains Position Sensors Encoders Additional laser safety information can be found on the Optek website. See application #221. Classification is not marked on the device due to space limitations. See package outline for centerline of optical radiance. Operating devices beyond maximum rating may result in hazardous radiation exposure. September 2003 Issue 2.1 Optek Technology, Inc.

Line 1 from 6 mA to 8 mA. Line 2 from 0 mA to 2 mA. Series Resistance is the slope of the Voltage-Current line from 8 to 12 mA. Slope efficiency, is the slope of the best fit LI line from 8 mA above threshold to 12 mA.
