Hamamatsu Photonics Europe Photo IC for optical switch S6841

The S6841 is a photo IC designed for optical switch applications, capable of operating in both transmission and reflection modes when paired with an LED. It features a compact transparent plastic package measuring 4.5 vó 5.5 mm and includes multiple terminal functions such as operation display, synchronous/asynchronous switching, and output logic switching. The device has a high sensitivity of 0.05 OºW/mm² (typical) and incorporates a built-in short-circuit protective circuit. The S6841 operates within a supply voltage range of -0.3 to +7 V and can handle a power dissipation of up to 250 mW. It is rated for an operating temperature range of -25 to +60 °C and a storage temperature range of -40 to +100 °C. The spectral response range is from 380 to 1120 nm, with a peak sensitivity wavelength at 820 nm. The device can tolerate background light levels up to 3500 lx, making it suitable for various lighting conditions. Engineers considering the S6841 for their projects should note its electrical characteristics, including current consumption and output current specifications, which are critical for integration into optical switching systems.
