Can Transistor serve as rectifier

[rakeshm5]

Hi guys,
            I have a small doubt regarding transistor as rectifier.                                                      Is there any possibility to use transistor in rectifier circuit,if yes how can we use  and how it is different from diode in rectifier circuit

You could probably use the collector-base junction of a transistor as a rectifier diode and its max voltage, max current and max power dissipation are listed on the datasheet.
But avoid using the emitter-base junction because it has avalanche breakdown (like a zener diode) with a reverse voltage of only about 6V for silicon transistors.
