The QSE257 from ON Semiconductor is an OPTOLOGIC IC photosensor designed for various detection applications. It features a medium wide reception angle of 50° and is housed in a sidelooker package with black epoxy material.
This photosensor operates with a supply voltage ranging from 4.0V to 16.0V and has a typical wavelength sensitivity of 880nm. The device includes a Schmitt trigger at the output for noise immunity and pulse shaping, making it suitable for direct TTL/LSTTL interface.
Key electrical characteristics include a positive-going threshold irradiance between 0.025 and 0.250 mW/cm², a hysteresis ratio of 1.10 to 2.00, and a maximum supply current of 5.0 mA. The output can drive up to ten TTL loads.
The QSE257 is built with bipolar silicon IC technology and is Pb-Free. Its operating temperature range is -40°C to 85°C, and it comes in a radial, 3-lead, side-view package.
