IR Emitter Die
Introduction
Pyreos is pleased to present infra-red light emitters ( light sources) provided as bare die for
customer’s to assemble into their own package and die arrangement. This die has pseudoblackbody emission properties, and is capable of being modulated over a wide frequency
range, and can be controlled by either the current or voltage supply. The die can be
incorporated into TO packages or into surface mount compatible packages. Please contact
Pyreos if you require a customized emitter die design.

All Device Parameters are nominal values and measured at 550C
