T-1 PACKAGE
NPN PHOTOTRANSISTOR
MID-38A22
Description
The MID-38A22 is a NPN silicon phototransistor mou-
nted in a lensed , special dark plastic package.The lens-
ing effect of the package allows an acceptance half view
angle of 20 that is measured from the optical axis to the
half power point .
Features
