The Honeywell SE5470-004 series consists of aluminum gallium arsenide infrared emitting diodes mounted in a TO-46 metal can package. These devices provide a narrow beam angle and exhibit 70% greater power output than gallium arsenide devices at the same forward current. The TO-46 packages offer high power dissipation capability and are ideally suited for operation in hostile environments. They are often used in applications requiring precise infrared emission, such as remote control systems, optical sensors, and industrial automation.
