1N6643US Discrete Semiconductor Products

Introduction

A 1N6643US is a single-phase, full-wave bridge rectifier diode meant for high temperature power-supply applications. It features a maximum repetitive reverse voltage rating of 2000 V and a maximum peak repetitive reverse voltage of 5000 V. It also has a maximum direct continuous current of 15 A.

TThe 1N6643US diode is primarily used in power supplies, particularly in high temperature applications like welding machines, radios, and other process control equipment. It is rated for junction temperatures up to 300 °C, making it an ideal choice for applications that receive high amounts of heat.

1N6643US Working Principle

A 1N6643US bridge rectifier works by converting an AC input waveform into a DC waveform. It does this by passing the incoming current through four diodes, which limit the current to only flow in one direction. Any voltage waveform that is greater than the threshold voltage of the diodes will be switched on and will allow current to pass freely through it.

When the first two diodes are forward biased, they allow current to pass freely through the bridge rectifier. When the last two diodes are forward biased, they switch the current back to the other side of the bridge rectifier, resulting in a DC waveform. This DC waveform is then used in power supplies and other electronic applications as a power source.

1N6643US Application

The 1N6643US bridge rectifier is used in a variety of power supply applications, including radios and welders. It is often used in high temperature applications due to its ability to operate at temperatures up to 300 °C. It is also used in a variety of high current applications, such as audio amplifiers, motors, and battery chargers.

The 1N6643US diode is also commonly used in other applications such as AC to DC converters, power supplies, and DC motor control circuits. It can be used in inverters and choppers, as well as in AC phase control circuits. Due to its high temperature rating, the 1N6643US is often used in applications that must withstand large amounts of heat, such as those found in welding machines.
