OIT18C13-ch. phototransistor array 0.45mm optical pitch on plastic SMD package General Description OIT18C consists in a silicon phototransistor’s monolithic array of 13 elements. The phototransistors have a common collector on the back substrate, which is tied to two pads and every emitter is accessible to specific pad. The optical pitch of the array is 0.45 mm, the LCC package electrical pitch is 1.27 mm. The active area of each element is 0.25 x 0.50 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 13 bit absoulte encoders Features ■ High uniformity of silicon cells ■ Monolithic construction, low optical pitch ■ High temperature range ■ High transparency resin ■ High gain ■ Designed to meet industrial specifications ■ Reference holes for precise mounting ■ Reference dots for very precise mounting ■ 0.45 mm optical pitch Pin Functions Optical Receivers Controls/drives Light sensors Function Common collector Phototransistor B Emitter Phototransistor D Emitter Phototransistor F Emitter Phototransistor H Emitter Phototransistor J Emitter Phototransistor L Emitter Not connected Not connected Common collector Not connected Phototransistor M Emitter Phototransistor K Emitter Phototransistor I Emitter Phototransistor G Emitter Phototransistor E Emitter Phototransistor C Emitter Phototransistor A Emitter Ordering Information OIT18C 13-ch. phototransistor array 0.45mm optical pitch on plastic SMD package
