Lateral Package
Description
The OPV282 is a high performance 850nm VCSEL pack-
aged for sensing applications. This product’s combina-
tion 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:
♦ Photoelectric Sensors
♦ Light Curtains
♦ Position Sensors
♦ Encoders
Maximum Forward Peak Current 30 mA
Maximum Reverse Voltage 5 Volts
Storage Temperature -40 to +125°C
Operating Temperature -40 to +85° C
Soldering Lead Temperature 260° C for 10 Seconds
Absolute Maximum Ratings
(T
A
= 25° C unless otherwise noted)
Features
• 850nm VCSEL Technology
• High thermal stability
• Low drive current/high output intensity
• Plastic Lateral Flat convex lens for extra narrow
beam angle.
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.

OPV282 Technical Data
NOTES:
(1) Threshold Current is based on the two line intersection method specified in Telcordia GR-468-Core. Line 1 from 6 mA to 8 mA. Line 2 from 0
mA to 2 mA.
(2) Series Resistance is the slope of the Voltage-Current line from 8 to 12 mA.
(3) Slope efficiency, is the slope of the best fit LI line from 8 mA above threshold to 12 mA.
