High Speed Photocouplers

Lite-On Inc. High Speed Photocoupler

Lite-On, Inc. and Digi-Key offer diode-transistor photocouplers

These diode-transistor photocouplers from Lite-On, Inc. consist of an AlGaAs LED optically coupled to high speed photodetector transistors. Separate connections for the bias of the photodiode and output transistor collector increase the speed up to several times that of a conventional phototransistor photocoupler by reducing the capacitance of the base-collector.
