This diode-transistor optocoupler uses an insulating layer between a LED and an integrated photodetector to provide electrical insulation between input and output. Separate connections for the photodiode bias and output-transistor collector increase the speed up to a hundred times that of a conventional phototransistor coupler by reducing the base-collector capacitance.
This single channel optocoupler is available in a 8-pin DIP package.
It is similar to the HCPL-4502, HCPL-0452, and HCNW4502 optocouplers but have increased common mode transient immunity of 15 kV/ms minimum at VCM = 1500 V guaranteed.
