Silicon Phototransistor and Photo Darlington in 1210 SMD Package OP525, OP525DA, OP525F OP525 and OP525DA Features: OP525F High Speed and High photo sensitivity Fast response time 1210 package size High Current Gain Water clear and black lens choices Narrow Viewing Receiving Angle Compatible with IR Reflow soldering process Moisture Sensitivity Level: MSL3 Description: These devices consist of an NPN silicon phototransistor and photo darlington mounted in a miniature SMD package with a 1210 size chip carrier that is compatible with most automated mounting and position sensing equipment. The OP525 devices have a 1.8mm domed lens and viewing acceptance angle of 25 with higher collector current gains due to the lenses on package. The OP525 and OP525DA have a water clear lens that senses ambient light to higher wavelengths for applications from 450nm to 1120nm. The OP525F has a black domed lens to reduce ambient light noise. The OP525 series are tested using infrared light for close correlation with Optek GaAs and GaAlAs emitters. Photo darlington devices are normally used in application where light signals are low and more current gain is needed than is possible with phototransistors.
