Diodes - Rectifiers - Single

A 1SS389, H3F is a single rectifier diode which operates in forward conduction direction. It is made up of a single N-type semiconductor that is housed in a small, round package. This diode is a step-up device, which means it can increase the power from the source of electricity to the desired electrical load or vice versa. It is widely used in applications such as AC/DC power supplies, over-voltage protection and low-level to high-level rectification.

The 1SS389, H3F is a preferred choice of rectifier diode in many designs because of its small size and its high current rating. Additionally, it has a fast switching time with a reverse voltage range of 400V and a forward current rating of 1A. It is generally used in switching power supplies, motor control circuits, and power switching circuits. The 1SS389, H3F is a valued component because it is highly reliable, minimal heat conduction and has a long working life.

The principal of operation of the 1SS389, H3F is determined by its semiconductor material and doping profile. The diode consists of a N-type semiconductor material which is sandwiched between two metal electrodes called an Anode and a Cathode. Current only flows from the Anode to the Cathode which is difficult to reverse. This means that electrical current can only pass through the diode in one direction, thus preventing any reverse current flow.

In addition to the high current rating, the 1SS389, H3F also has a low forward voltage drop which is ideal for high current applications or otherwise known as power switching applications. This low forward voltage drop is achieved due to its comparatively high doping concentrations as compared to other rectifier diodes. It is not only capable of rectifying AC input into DC output with great precision, it is also able to stabilize output voltage to essential levels.

To sum up, the 1SS389, H3F single rectifier diode is one of the most reliable, efficient, powerful and economical components available in the market. It is a great choice for power rectification, power control and protection in DC/DC power conversion applications. The 1SS389, H3F is an excellent choice of diode for many power electronics applications due to its small size and high current rating.
