The S12498 is a silicon photodiode designed for applications such as non-destructive X-ray inspection and general industrial measurement. It features a spectral response range from 400 to 1100 nm, with a peak sensitivity wavelength at 920 nm. The photosensitive area measures 6.0 vó 6.0 mm, and the device allows for easy mounting of a scintillator directly on the chip due to its back-illuminated design, which eliminates the presence of wires in the sensitive area. In terms of electrical characteristics, the S12498 has a short circuit current of 75 µA under standard illumination conditions and a dark current of up to 150 pA. The device operates effectively within a temperature range of -20 to +60 °C and has a maximum reverse voltage rating of 10 V. The rise time is specified at 15 µs, and the terminal capacitance is approximately 330 pF at 0 V. This photodiode is suitable for engineers looking for reliable performance in measurement and inspection applications.
A scintillator can be mounted directly on the chip.
The S12498 is a Si photodiode suitable for non-destructive inspection of baggage and the like and general industrial measurement. As it is a back-illuminated photodiode, photosensitive area does not have wires, and therefore a scintillator can be mounted directly on the photodiode.
