The ULN2003 devices are high-voltage, high-current Darlington transistor arrays. Each consists of seven NPN Darlington pairs that feature high-voltage outputs with common-cathode clamp diodes for Simplified Block Diagram switching inductive loads. The collector-current rating of a single Darlington ..

The EL817 Phototransistor Photocoupler series of devices each consist of an infrared emitting diodes, optically coupled to a phototransistor detector. They are packaged in a 4-pin DIP package and available in wide - lead spacing and SMD option.EL817 series of devices are Photo transistor based photo..

The TCRT5000 and TCRT5000L are reflective sensors which include an infrared emitter and phototransistor in a leaded package which blocks visible light. The package includes two mounting clips. TCRT5000L is the long lead version.Features of TCRT5000 Reflective Infrared Optical Sensor Photoelectric Sw..

The photodiode is a semiconductor device that converts light energy into electrical energy causes current flow. The current is generated when photons are absorbed in the photodiode. A small amount of current is also produced when no light is present.Features of Photodiode 5MM:Excellent linearity of ..

The IR photo diode or IR receiver is a high speed & high sensitive diode. The photodiode is spectrally matched to infrared matching diode. It has fast response time, high photo sensitivity and small junction capacitance.Features of Photodiode(3 MM):Package type: leaded.Dimensions (in mm): 3mm.Ra..
