SD5443

SD3443/5443 Silicon Phototransistor FEATURES • TO-46 metal can package • Choice of flat window or lensed package • 90¡ or 18¡ (nominal) acceptance angle option • Wide operating temperature range (- 55¡C to +125¡C) • External base connection for added control • High sensitivity • Mechanically and spectrally matched to SE3450/5450, SE3455/5455 and SE3470/5470 infrared emitting diodes INFRA-57.TIF DESCRIPTION The SD3443/5443 series consists of an NPN silicon phototransistor mounted in a TO-46 metal can package. The SD3443 has flat window cans providing a wide acceptance angle, while the SD5443 has glass lensed cans providing a narrow acceptance angle. The TO-46 packages are ideally suited for operation in hostile environments. The base is connected on all SD3443 and SD5433 standard products.
