The transistor is a "single direction current flow" device. Typically, for an NPN device, the collector must be more positive than the emitter for the device to bias on.

You could use the transistor in an AC circuit, but it would only conduct on half the cycle.

They are. Many logic ICs are based on transistor switching.
