The S4753-02 silicon PIN photodiode was designed for fast detection of blue and blue-green diode lasers. The device features a spectral response range from 320 to 1000 nm, with peak sensitivity at 800 nm. Minimum sensitivity at 425 nm is 0.22 A/W and at 530 nm is 0.30 A/W. The detector has a cutoff frequency of 1.2 GHz and a reverse voltage of 5 V. Dark current is typically 1 pA.
