3-ch. phototransistor array 0.60mm
optical pitch on plastic SMD package
OIT29 consists in a three elements silicon
phototransistor’s monolithic array.
The phototransistors have a common collector, every emitter is available as a pad. The pitch of the silicon arrays is 0.6 mm, while the component electrical pitch is 1.27 mm. The active area of each element is 0.2 x 0.45 mm. The encapsulant is an high quality microelectronic transparent silicone resin: its transmission value is greater than 95% between 300nm and 400nm while it is very close to 100% in the range 400-900nm. The phototransistors have an antireflective coating that
guarantees a good spectral bandwith (500-950nm) with a peak responsivity at 755nm. The main advantages of this device are the high uniformity of the silicon sensors in all elctro-optical parameters, due to the monolithic construction and the high optical responsivity, due to the antireflective coating deposited on the phototransistor’s areas.
