Description
TEFT4300 is a high speed and high sensitive silicon NPN epitaxial planar phototransistor in a standard T–1 (ø 3 mm) plastic package.
The epoxy package itself is an IR filter, spectrally matched to GaAs IR emitters with λp ≥ 900nm).
The plastic lens provides a wide viewing angle of ± 30°.
