The S4KW4C-2N is a rectifier diode array, which is made up of four ultrafast rectifier diodes connected in parallel in a common anode configuration. It has a maximum allowable reverse recovery current of 2 A and a low reverse leakage current of 0.3 μA. It is commonly used in high-frequency switching power supplies, general-purpose power supplies, and high-efficiency LED lighting applications.

Working Principle

The S4KW4C-2N employs a special design of rectifier diodes connected in parallel in a common anode configuration to minimize switching losses. This allows it to operate at high-frequency switching frequencies, which is ideal for low-power applications such as LED lighting. As the rectifier diodes are connected in parallel, the current can be split between them, resulting in a lower voltage drop across diodes and a lower voltage drop across the load. Additionally, the low reverse-leakage current of the S4KW4C-2N allows it to operate efficiently in high-voltage switching power supplies.

Application Fields

The S4KW4C-2N rectifier diode array is primarily used in high-frequency switching power supplies. This is due to its ability to operate efficiently at high switching frequencies and its low reverse-leakage current. Its high reverse-recovery current makes it suitable for applications that require a high current, such as motor applications. Additionally, it is also used in general-purpose power supplies and in high-efficiency LED lighting applications.

The S4KW4C-2N can also be used in DC-DC converters, as its low reverse-leakage current increases the efficiency of the converter. Additionally, its high reverse-recovery current and low forward-voltage drop make it suitable for applications where fast switching is required, such as in data transmission applications. It is also used in level crossings and stop-start applications, where its low reverse-leakage current increases the efficiency of the circuit.

In addition, the S4KW4C-2N can be used in various other applications, such as in AC-to-DC converters, solar panel power supplies, AC battery chargers, and automotive applications.
