Diodes are a basic building block of electronic components, and rectifiers are an essential class of diode. At the most basic level, they are two-terminal semiconductor devices that allow current to flow in one direction only, and they are used to convert AC signals into DC signals. The SS26/54 is an example of a single rectifier, which is a type of rectifier that consists of a single device.

The SS26/54 is an ultrafast-recovery rectifier specifically designed for high-frequency applications. It is a low forward voltage drop rectifier that is suitable for high-frequency bridge rectifiers and DC-to-DC converters. It features a low forward voltage drop, fast switching time, and low thermal impedance, making it suitable for use in modern, highly efficient power conversion applications.

The SS26/54 has an average rectified forward current of 26A and a repetitive reverse voltage of 54V. It has a very low forward voltage drop of 0.39V at a current of 25A. The maximum reverse recovery time of this diode is 95ns, and its maximum average forward power dissipation is 75W. It has a thermal resistance of 2.1°C/W junction to case, offering good thermal performance.

The way the SS26/54 works is relatively straightforward. When forward biased, the diode creates a low resistive path that allows current to flow in one direction only. The current causes a voltage drop across the diode, and this voltage drop is proportional to the current flowing through it. When the input voltage is alternating, a bridge rectifier is used to rectify it and convert it to a DC voltage. The SS26/54 is an ideal choice for this application due to its low voltage drop and fast switching time.

When the voltage is reversed, the diode becomes reverse biased and the current flow is blocked. This is known as the “reverse recovery”, and the SS26/54 has one of the fastest reverse recovery times of any rectifier on the market. This makes it suitable for high-frequency applications, where fast switching is required.

The SS26/54 is an ideal rectifier for use in high-frequency bridge rectifiers and DC-to-DC converters. Its low forward voltage drop, fast switching time, and low thermal resistance make it suitable for use in modern, highly efficient power conversion applications. It has a maximum average forward power dissipation of 75W and a maximum reverse recovery time of 95ns, making it an excellent choice for high-frequency applications.
