OPV280

Vertical Cavity Surface Emitting Laser in Plastic Lateral Package Features • • • • • 850nm VCSEL Technology High thermal stability Low drive current/high output intensity Narrow and concentric beam angle Plastic Lateral Flat Lens Package Description Absolute Maximum Ratings (TA = 25° C unless otherwise noted) The OPV280 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. 30 mA Maximum Reverse Voltage 5 Volts Storage Temperature Operating Temperature Soldering Lead Temperature Applications include: ♦ ♦ ♦ ♦ Maximum Forward Peak Current -40 to +125°C -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 cause devices to exceed rated classification September 2003 Issue 2.2 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. Optek reserves the right to make changes at any time in order to improve design and to supply the best product possible. Optek Technology, Inc.
