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 (- 55C to +125C) * 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.
