Are transistor optocouplers faster than photodiodes?

Transistor optocouplers are slower than photodiode types but much faster than photocells. Depending on the biasing of an individual device, transistor devices are capable of a wide range of current transfer ratios, and both types are well-suited to "stepping up" input current.

OPTOCOUPLER DEVICES AND APPLICATION

optocoupler (or an optoelectronic coupler) is basically an interface between two circuits which operate at (usually) different voltage levels. The key advantage of an optocoupler is the electrical isolation between the input and output circuits. With an optocoupler, the only contact between the input and the output is a beam of light.
