Each OP993 and OP999 device consists of a PIN silicon photodiode molded in a dark blue injection molded shell package

that provides excellent optical and mechanical axis alignment, optical lens surface, control of chip placement and

consistency of the outside package dimensions.

OP993 has a TO-18 package style and a wide receiving angle that provides excellent on-axis coupling. OP999 has a T-1¾

package style and a narrow receiving angle that provides excellent on-axis coupling.

Both devices are 100% production tested for close correlation with OPTEK GaAIAs emitters.

Please refer to Application Bulletins 208 and 210 for additional design information and reliability (degradation) data.

Applications:

 Choice of TO-18 (OP993) or T-1¾ package (OP999)

 Small package style ideal for space-limited applications

 Linear response vs. irradiance

 Fast switching time

 Choice of narrow or wide receiving angle

To avoid stress cracking, we suggest using

ND Industries’ Vibra-Tite for thread-locking.

Vibra-Tite evaporates fast without causing

structural failure in OPTEK'S molded plastics.
