OIT25C 6-ch. phototransistor array 0.68mm optical pitch on plastic SMD package General Description OIT25C consists in a six single diced silicon phototransistor. The phototransistors have a common collector on the back substrate, which is tied to a single pad and every emitter is accessible to specific pad. The optical pitch of the array is 0.68 mm, the LCC package electrical pitch is 1.27 mm. The active area of each element is 0.20 x 0.45 mm2. The advantages of this product are the high uniformity of the silicon sensors, due to the monolithic construction and to the extremely controlled microelectronic process, the high stability of the signal and the high optical responsivity, due to the antireflective coating deposited on the phototransistor’s areas. The encapsulant is a clear silicone material, having medium hardness, in order to be robust against RoHS soldering processes and high optical performances (transmittance close to 100% in the range 300-900nm). Two reference marks are available for the precise collimator positioning. Applications Optical encoders Incremental encoders Features ■ High uniformity of silicon cells ■ High temperature range ■ High transparency resin ■ High gain ■ Designed to meet industrial specifications ■ Reference holes for precise mounting ■ Reference dots for very precise mounting Pin Functions Optical Receivers Controls/drives Function Not connected Phototransistor A Emitter Phototransistor C Emitter Phototransistor E Emitter Phototransistor F Emitter Phototransistor D Emitter Phototransistor B Emitter Common collector OIT25C 13-ch. phototransistor array 0.68mm optical pitch on plastic SMD package
