S12426_15 Datasheet, PDF (1/5 Pages) Hamamatsu Corporation – Low bias operation, high-speed Si APD for 900 nm

Si APD
S12426 series
Low bias operation, high-speed Si APD
for 900 nm
The S12426 series Si APDs are designed to provide a peak sensitivity wavelength in the 900 nm band where optical
rangefinders are increasingly used. The S12426 series deliver faster response and lower bias operation than our existing Si APD
(S9251 series).
Features
Peak sensitivity wavelength: 840 nm (gain=100)
Low bias operation: Breakdown voltage=200 V max.
High-speed response: Cutoff frequency=650 MHz typ.
(S12426-02, λ=900 nm, M=100)
