1N6843 is a glass-passivated single rectifier diode. It is a kind of diode usually used in power electronic circuits. There are some characteristics to help you recognize the 1N6843 diode.

The first characteristic of the 1N6843 diode is voltage. It has a nominal voltage of 600V and it is suitable for power supplies with a voltage exceeding 500V. The second characteristic is the maximum average current. This diode can withstand a maximum current of 2A which is good for mainstream power supplies. The third characteristic is its ability to withstand reverse voltage. It can withstanding voltage up to 600V which makes it suitable for power supplies with a voltage greater than 500V.

The fourth characteristic of 1N6843 diode is its non-linear resistance. When the voltage is higher, it will increase the diode resistance and decrease the current passing through the diode. This makes it suitable for power supplies with a high input voltage, as the current passing through the diode will be limited.

The fifth characteristic is that the 1N6843 diode is able to withstand temperatures up to 150 degrees Celsius. This means it can withstand high temperature in power electronic systems. The sixth characteristic is its low-leakage current. The 1N6843 diode can limit the current passing through the diode to a few milliamps when in forward direction.

The seventh characteristic of this diode is that the maximum reverse recovery time. The 1N6843 diode is able to switch from a forward-biased state to a reverse-biased state within a few nanoseconds. This makes it ideal for high speed power supplies.

The working principle of the 1N6843 diode is very simple. When the diode is connected to the power supply\'s positive terminal, current flows from the positive terminal to the negative terminal. When the voltage is high enough, the diode\'s non-linear resistance increases, limiting the current passing to the negative terminal. This helps to protect the power supply from overloading.

The 1N6843 diode is usually used in automotive applications, electronic circuits, power supplies, AC adapters, and other electronic devices. It is an ideal choice for most power electronic applications, as it is capable of withstanding high voltage, it is able to limit the current passing through the diode, and it has a low reverse-recovery time. All of these features make it a reliable choice.
