A 1N4004AT-82 is a type of single rectifier diode. It is a rectifier that is used to convert alternating current (AC) to direct current (DC) and to protect the electrical circuits. A diode is a two-terminal semiconductor device that uses electric current to move the charge carriers such as electrons or holes through the device. It acts as a gate to allow the current in one direction and to block the current in the opposite direction. The 1N4004AT-82 diode is specifically used in power applications where it is typically used as a reverse polarity protection device. It is a rugged, reliable, and cost-effective device.

The 1N4004AT-82 diode is a power rectifier made from silicon and is formed from a P-type semiconductor material with a heavy-duty epoxy moulded case for strong mechanical integrity. It has high surge current and low forward voltage drop with a reverse recovery time of 150ns. There is no in-built limiting resistor required and the power dissipation of the device is up to 20 Watts. It has a maximum repetitive surge peak reverse voltage of 400 Volts and a maximum repetitive peak forward current of 0.1 Amps. Its maximum junction temperature is 150oC.

A 1N4004AT-82 diode can be used in a variety of applications including line bracing AC power supplies, relay and motor control, AC/DC converters, and line drop compensation circuits. It is also often used in battery charging applications where it is typically used as a polarity protection device. It can be used to protect electrical circuit boards from electric surges or to provide over-voltage protection by preventing voltages greater than the diode forward voltage drop. It is also commonly used to ensure that current flows in the right direction within electrical circuits.

The 1N4004AT-82 diode works on the principle of diode action. In diode action, a semiconductor diode is connected with one side to the external circuit and the other side to the internal circuit path. When a voltage is applied across the two terminals, a current flows only in the forward direction, which means a negative voltage applied to the anode will cause a current flow and a positive voltage applied to the anode will cause no current flow. When a voltage is applied in the reverse direction, the diode is said to be in a reverse-biased condition and no current will flow through the device.

The 1N4004AT-82 diode is a popular device and widely used in diverse applications. It has good durability and is available in a variety of packages to allow for easy mounting and installation. The device is also cost-effective and reliable, making it one of the most popular rectifier devices available on the market.
