DESCRIPTION
The SE3450/5450 series consists of a gallium arsenide
infrared emitting diode mounted in a TO-46 metal can
package. The SE3450 series has flat window cans
providing a wide beam angle, while the SE5450 series
has glass lensed cans providing a narrow beam angle.
The TO-46 packages offer high power dissipation
capability and are ideally suited for operation in hostile
environment.
