TT Electronics - Optek Technology OP535A Silicon Photodarlington

The OP535A is a silicon NPN photodarlington packaged in a green plastic mold. It features a narrow reception angle that offers excellent on-axis coupling. This device is fully tested using infrared light to ensure close performance correlation with Opto Ken GaAs and GaAlAs emitters. Designed for applications requiring low light signal levels and higher current gain, it is ideal for use in portable devices, sensing, and instrumentation. The device is compact with a small package size and includes a 0.050-inch (1.27mm) lead spacing.
