Low bias, high-speed Si APD for 900 nm


The S12426 series Si APD are designed to provide a peak sensitivity wavelength in the 900 nm band where optical rangefinders are increasingly used. The S12426 series delivers faster response and lower bias operation than our existing Si APD (S9251 series).

- 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)
