The OPV302 is a Vertical Cavity Surface Emitting Laser (VCSEL) packaged in a dome lens TO-46 package.
VCSELs offer many advantages in sensing applications when compared to infrared LEDs. These devices require
substantially lower drive currents to obtain the same amount of output power as LEDs. This feature allows
VCSELs to be used in low power consumption applications such as battery operated equipment.
The dome lens packaging creates a narrow beam angle from the device. Long distance applications may benefit
from this feature as secondary optics may be eliminated, reducing total system cost. The OPV302 is optically and
spectrally compatible with Optek’s standard detector products such as the OP800 series phototransistors, OP830
series photodarlingtons and the OP910 photodiode.

Classification is not marked on the device
due to space limitations. See package out-
line for centerline of optical radiance. Oper-
ating devices beyond maximum rating may
result in hazardous radiation exposure.

NOTES:
(1) RMA flux is recommended. Solder dwell time can be increased to 10 seconds when flow soldering.
(2) Threshold Current is based on the two line intersection method specified in Telcordia GR-468-Core. Line 1 from 4 mA to 6 mA. Line 2 from 0 mA to 0.5 mA.
(3) Series Resistance is the slope of the Voltage-Current line from 5 to 8 mA.
(4) Slope efficiency, is the slope of the best fit LI line from 5 mA to 8 mA with 0.25mA test intervals.
