Carrollton, Tex. Now available in a 1206 case size, TT electronics OPTEK Technology's new series of NPN silicon transistors are designed for infrared detection in sensing applications. The new miniaturized surface-mount OP520/OP521 series devices tout fast response times of 15 microseconds for machine automation, miniature optical encoders and other high-speed, non-contact position sensing systems.
The OP520 and OP521 series devices are silicon NPN phototransistors designed to detect 880-nm wavelength infrared light. Both IR detectors are packaged in a 1206 chip with a flat molded lens. The OP520 features an opaque lens to shield it from ambient light, while the OP521 lens is water clear, giving it a wider response range.
Electrical performance of the OP520/521 series is characterized at a collector-emitter voltage of 30 V, emitter-collector voltage of 5 V, and collector current of 20 mA. The devices offer power dissipation of 75 mW at 25°C. They are RoHS-compliant, as well as compatible with high temperature (260°C) lead-free soldering processes, and are rated for operation from -25°C to 85°C.
The OP520/OP521 Series are designed to be mechanically and spectrally matched to OPTEK’s OP250 series of surface-mount infrared LEDs.
Typical pricing for the OP520/OP521 series phototransistors starts at $0.20 each in quantities of 1,000. Samples are available immediately. Production quantity lead times are from stock to eight weeks, if not available in stock.
