Difference between diode and rectifier

The diode and rectifier both semiconductor device but are used in different application due to their different functioning. A diode is a device that allows the flow of current in one direction only while in rectifier is a diode that is able to convert the current from AC to DC. Here this post gives the difference between diode and rectifier to better understand this topic.

Definition:

Diode: A diode is a semiconductor device which conducts when it is forward biased and becomes open circuit when it is reversed biased.
Rectifier: Rectifier is a circuit which consists of a diode, step down transformer and filter circuit which collectively converts AC into pulsating DC.

The main key difference between diode and semiconductor are listed below:
  • The diode is a semiconductor device but a single element or entity in an electronics circuit, While in rectifier itself is an electronics circuit which consists of several elements as its components among which diode holds a crucial place.
  • A diode is a device that allows the flow of current in one direction only, a rectifier is a diode that able to convert from AC to DC.
  • A diode is a semiconductor device which conducts uni-directionally and acts as a switch, while the rectifier is the semiconductor device which converts alternating current into pulsating direct current.
  • Current carrying capability of the diode in low, while rectifier has higher current capability than the conventional diode.
  • Diode example like tunnel diode, PIN diode, Photodiode, Zener diode, etc while the rectifier is basically divided into two categories that are single phase and 3 phase rectifier and single phase is also further subdivided into half wave rectifier and full wave rectifier.
  • A diode is used in switches, clippers and clampers, etc while the rectifier is used in computers, battery, chargers, modulators, demodulators, DC motors, etc.
