A diode rectifier is a vital component in power supply circuitry which is used to convert alternating current (AC) input voltage to direct current (DC) output voltage. The single diode rectifier is composed of a single diode connected in series with the AC source, typically the mains power supply. These rectifiers are often referred to by their model number, with the SET121204 being the commonly used unit.

The key components of a diode rectifier are the diode itself and a resistor. As with all electrical components, a resistance is needed to keep the current within safe limits. The resistor in a rectifier acts as a voltage divider so that a lower voltage is applied to the diode. This keeps the diode from being damaged by over-voltage.

When the AC input voltage travels through the diode, it is rectified or converted to direct current (DC). The diode can be thought of in terms of a one way valve, letting the current through in only one direction. As the voltage passes through the diode, the current flows from the anode (positive) to the cathode (negative).

The output DC voltage from the rectifier is determined by the peak-to-peak voltage of the AC Input voltage divided by the ratio of the voltage divider resistor with the diode. This is known as the chopping voltage. The chopping voltage is then applied to the diode and a lower DC voltage is the result on the output side of the diode. The SET121204 rectifier has a chopping voltage of 5.3V.

The SET121204 is rated at 1A, indicating that its maximum current output is 1A. The actual current output is based on the voltage applied to the diode. The higher the voltage, the higher the current. Generally speaking, the power dissipation of a diode is equal to the voltage across the diode multiplied by the current flowing through it.

Rectifiers are a staple of power supply design and the SET121204 is a very common model. It is used in many high power and low voltage applications such as filtering power, providing protection from reverse polarity, and isolating circuits from input AC sources. These rectifiers can also be used for converting AC line voltages to DC power for many automotive and industrial applications.

The SET121204 diode rectifier is a versatile device for power conversion in many different applications. Its working principle is straightforward, allowing for easy installation into various systems and circuits. Its high current and wide input voltage range make it an ideal choice for many different applications.
