SD1440-004

SD1440 Silicon Phototransistor FEATURES • Compact, metal can coaxial package • 24¡ (nominal) acceptance angle • Wide sensitivity ranges • Wide operating temperature range (- 55¡C to +125¡C) • Mechanically and spectrally matched to SE1450 and SE1470 infrared emitting diodes INFRA-63.TIF DESCRIPTION The SD1440 is an NPN silicon phototransistor mounted in a glass lensed metal can coaxial package. The package may have a tab or second lead welded to the can as an optional feature (SD1440-XXXL). Both leads are flexible and may be formed to fit various mounting configurations.
