The SDM40E20LS-7-F is a rectifier diode array. These diode arrays are composed of several identical diode cells connected in parallel to increase the current-handling capacity of the array. As with all diodes, the SDM40E20LS-7-F is a two-terminal, unidirectional device that conducts current in one direction only. This is due to its internal construction, which consists of two differently doped semiconductor layers. The two layers are attached and form a junction, which creates a barrier to current flow in the opposite direction. This creates a rectifier effect, allowing for electrical current flow in one direction only.

The SDM40E20LS-7-F diode array has a low VF (forward voltage drop or voltage drop across the semiconductor junction) of 0.39V at IF=20A, and a high surge capability of up to 250A. This diode array also has a low thermal resistance junction-to-case (RθJC) of 1.4°C/W for improved heat dissipation and a high resistance to reverse recovery, ensuring reliable operation and preventing the release of transient oscillations.

The application field of this diode array is wide, due to its practical advantages. It is used in both standard, general-purpose rectifier circuits, such as automotive and converters, and also in higher-power, higher-current applications, such as welding and electrolysis equipment. Its fast switching speed is also applied to light dimming, PWM motor control, and power supplies.

The working principle of the SDM40E20LS-7-F diode array is simple and efficient. When forward-biased, the diode array is able to conduct the electric current through itself and its output is positive, depending on the input voltage and direction of current flow. When reverse-biased, a barrier voltage is formed, prohibiting any current from flowing through. This makes a diode array ideal for rectifying AC electricity and will have no effect on the other components in the circuit.

The SDM40E20LS-7-F diode array is an excellent choice for applications where high current and surge current needs are present. Its low VF and excellent thermal properties offer reliable current-handling capacity, while its fast switching speed ensures accuracy and efficiency. This diode array is well-suited for both standard and high-power applications and is becoming increasingly popular in a variety of markets.
