S8594 uses a window-less package with no protection for the photodiode chip. Always take the following precautions when
handling.
I Handling precautions
G Handle the photodiode in a clean room.
G Never touch the photodiode chip surface and wire bonding.
G Wear dust-proof gloves and dust-proof mask.
G Use an air dust cleaner to blow dust and foreign matter away from the photodiode chip surface.
G Do not clean the photodiode by any method other than air blow.
