Description
The OPV280 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
Absolute Maximum Ratings (TA = 25°C unless otherwise noted)
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
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

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.
Optek reserves the right to make changes at any time in order to improve design and to supply the best product possible.
