This document is the OP169SL datasheet, which mainly introduces the product's features, parameters, applications, etc.
This document is a product bulletin describing GaAs Plastic Infrared Emitting Diodes of types OP169SL, OP169SLD, and OP169SLC. The devices are molded in end-emitting miniature clear packages with an integral lens designed for a narrow beam angle. They are mechanically and spectrally matched to the TRW OP509 phototransistor series.
Yes, they are mechanically and spectrally matched to the OP509 phototransistor series.
The absolute maximum continuous forward current is 20 mA.
