silicon phototransistor sd3443/5443 description 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 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. infra-57.tif outline dimensions in inches (mm) 3 plc decimals 0.005(0.12) tolerance 2 plc decimals 0.020(0.51) 3. collector 2. base 1. emitter (tab) leads: .046(1.17) .036(.91) 2 1 3 dia.
