Honeywell SD3443002 Silicon Phototransistor

The Honeywell SD3443/5443 series consists of an NPN silicon phototransistor mounted in a TO-46 metal can package. The SD3443 features a flat window providing a wide acceptance angle, while the SD5443 has a glass lensed can for a narrower acceptance angle. These packages are suitable for operation in hostile environments. The base is connected on standard products, offering added control. The device is mechanically and spectrally matched to Honeywell SE3450/5450, SE3455/5455 and SE3470/5470 infrared emitting diodes, making it ideal for light detection and control applications.
