The device is constructed from silicon epitaxial base planar technology. It is available in the hermetically sealed 2-pin TO-263AA package, with a wide wire lead span and a special molding compound for increased reliability. The device features a reverse diode with a high current capacity and low forward voltage drop. The device is particularly well suited for use in high-voltage power supplies, where its capability to reduce forward voltage drop and achieve reliable current rectification is especially valuable.

In order to understand how the JANTX1N485B works, it is important to have a general knowledge of how diodes function. A diode is an electrical device which only allows current to flow in one direction. It is composed of two electrically connected layers of semiconductor material, known as P and N-type layers. When the voltage across the diode is positive, no current passes through the junction. This is known as forward blocking. Conversely, when the voltage across the diode is negative, current is able to pass through the junction. This is referred to as forward conduction.

The JANTX1N485B is designed to work in a similar fashion as other rectifier diodes. It is designed to block current in the forward direction, while allowing current to pass through in the reverse direction. This process is known as rectifying current. The device works in this fashion by forming a reverse-biased junction in the circuit. When the reverse voltage applied is greater than the forward voltage drop, current passes through the device in the reverse direction. As the reverse voltage is reduced, the current flow through the diode is blocked. The device is then reverse biased and current can no longer flow.

The JANTX1N485B is an ideal choice for use in high power, harsh industrial environments and in applications requiring superior surge capacity and high forward current ratings. Combining efficient current rectification with low reverse leakage current and voltage, this device is well suited for use in a variety of infrastructure and industrial applications.
