S8284 is a high-sensitivity Si PIN photodiode optimized for violet laser detection and especially ideal for optical disc pickups using a violet laser
which has now been put into practical use. S8284 offers 30 % higher sensitivity (at 410 nm) than the conventional type (S1651). S8284 also
features high-speed response at a low bias voltage.
