Diodes are semiconductor components which allow current to flow through them in one direction only. Rectifiers are electronic components that convert alternating current (AC) to direct current (DC). Single rectifiers are diodes that are designed to pass current in one direction only and block it from passing in the opposite direction. The 1N4002-G diode is a general-purpose rectifier that is used in many circuits where DC voltage levels from a low to a moderate level are required.

The 1N4002-G diode is a single rectifier rated for 1A at a Vf of 1.2V for general-purpose equipment. It has an anode (A) and a cathode (−). When the anode is positive with respect to the cathode, it will conduct current, allowing it to flow through the diode. When the voltage is reversed, no current will flow. The current will only flow through the diode when the anode is more positive than the cathode. This is called the forward bias.

The 1N4002-G diode is a thermionic diode and is typically used in general-purpose rectifier circuits. It is well-suited for use in circuits with high inrush currents, such as those found in automotive and power supply applications. It has a low reverse leakage current and is externally rated for up to 800V. Due to its high reliability and low cost, the 1N4002-G diode is commonly used in many applications including power supplies, motor control circuits, low-voltage level converters, and automated test equipment.

When used as a rectifier, the 1N4002-G diode is placed in series with a load. When the input voltage is positive, the diode is forward biased and current flows through the load. When the input voltage is negative, the diode is reversed biased and no current flows. This allows for the conversion of AC voltage to DC voltage by rectifying it with the 1N4002-G diode. Additionally, the diode can be used to protect components from over-voltage damage by safely dropping any voltage spikes or transients above the diode’s rated breakdown voltage.

The 1N4002-G diode is a widely used general-purpose rectifier for AC to DC voltage conversions. It is highly reliable and offers good current regulation. Its low Vf, low thermal resistance and low power dissipation make it suitable for many applications. Its small size makes it a preferred choice when space is at a premium. It is also commonly used in power supplies, motor control, low-voltage level converters, and automated test equipment.
