TCST1202 Description

Short technical summary and product information.

The Vishay TCST1202 is a transmissive optical sensor designed for applications requiring precise object detection. It incorporates an infrared emitter and a phototransistor, positioned face-to-face within a leaded package that effectively blocks ambient visible light. This configuration makes it suitable for use as an optical switch or photo interrupter.

Key specifications include a typical gap of 3.1 mm and an aperture width of 0.5 mm. The sensor provides a typical output current of 2 mA under test conditions. It operates with an emitter wavelength of 950 nm and features a daylight blocking filter. The component is lead-free and compliant with RoHS3 directives.

The TCST1202 is housed in a leaded package with dimensions of 11.9 x 6.3 x 10.8 mm, designed for through-hole mounting. Its absolute maximum ratings include a total power dissipation of 250 mW at 25°C ambient temperature, with an operating ambient temperature range of -55°C to 85°C.
