Hamamatsu Corp. said its new S9251 series of silicon (Si) avalanche photodiodes (APDs) deliver excellent sensitivity in the near infrared (NIR) range and high operational stability for use as a rangefinder and in spatial light transmission applications such as optical telecommunications systems and digital computers.

The four photodiodes cover a spectral response range of 440nm to 1,100nm and achieve peak photosensitivity of 0.52A/W at 860nm. The S9251 series also achieves a peak Quantum Efficiency (QE) of 72 percent at 900nm.

Typical dark current for the S9251-02, S9251-05, S9251-10, S9251-15 is 0.1-, 0.2-, 0.4- and 0.8nA, respectively. Both the S9251-02 and S9251-05 offer a 400MHz cutoff frequency, while the cutoff frequency is 380MHz and 350MHz for the S9251-10 and S9251-15, respectively. Effective active areas range from 0.2mm diameter for the S9251-02 to 1.5mm diameter for the S9251-15.

The S9251-02 and S9251-05 are packaged in TO-18 cans while the S9251-10 and S9251-15 are available in TO-5 cans. The operating temperature range of the S9251 devices is 20C to 85C.

Prices start at $32.56 in OEM quantities. Delivery is five to six weeks.
