IR-enhanced Si PIN photodiode



Enhanced near IR sensitivity, using a MEMStechonology

The S12028 is Si PIN photodiode that offers enhanced near infrared sensitivity due to a MEMS structure formed on the backside of the photodiode. The S12028 offers signifi cantly higher sensitivity than our previous product (S5821).

- High sensitivity in near infrared range: 0.5 A/W (λ=1060 nm)
- Photosensitive area: φ1.2 mm
- High reliability package : 2-pin TO-18
