The S1226-44BK is a silicon photodiode with a 3.6 × 3.6 mm photosensitive area, packaged in a TO-5 case, designed for UV to visible light detection with suppressed near-infrared sensitivity. It operates within a reverse voltage range of -40 to +100 °C and a storage temperature range of -55 to +125 °C. The device uses borosilicate glass as the window material and exhibits a spectral response range of 320 to 1000 nm, with a peak responsivity at 720 nm. It has a typical short-circuit current of 10 µA at VR=10 mV, a shunt resistance of 1 GΩ at VR=10 mV, and a terminal capacitance of 10 pF at VR=0 V. The dark current is specified at 20 pA maximum. The photodiode has a spectral responsivity of 0.10 to 0.12 A/W from 190 to 1000 nm and a temperature coefficient of dark current of 1.0 %/°C.
