The SK110B M4G is a single diode rectifier that is typically found in low voltage power supply applications. It is a three-terminal discrete device rated for operating at as low as 150 mA with a maximum working voltage of 400V. This rectifier has a typical forward voltage of 1V, a reverse current of up to 1uA, and a thermal resistance of 0.25°C/W.

This diode rectifier is well suited for a wide range of applications including rectified AC-DC power supplies, eliminating the need for a large AC transformer while still allowing the output current to remain over 90%. It is also commonly used as a freewheeling diode in DC inverters and can also be found in both battery charger designs and uninterruptible power supplies (UPS). Finally, these diodes are often used in reverse polarity protection circuits to ensure that the wrong polarity does not cause an overload or damage to the circuit.

At its core, the SK110B M4G rectifier is a three-terminal discrete device consisting of a diode and a resistor that are connected in series. The diode is connected to the anode and cathode, while the resistor is connected between the anode and the third terminal. This resistor serves to restrict the flow of current and convert the AC signal into DC. Additionally, the diode helps to reduce the amount of stray current and loss of voltage.

When operating, the SK110B M4G has two distinct working states: forward biased and reverse biased. During the forward biased state, the anode of the diode is connected to the positive voltage and the cathode to the negative voltage. This brings the voltage over the diode to a positive value, which allows the conduction of current. On the other hand, during the reverse biased state, the diode breakdown voltage prevents the conduction of current and the SK110B M4G does not work.

By combining a low forward voltage, a reverse leakage current, and a fast reverse recovery time, the SK110B M4G is easily capable of handling modern power requirements. This, coupled with its ability to operate in either the forward or reverse biased state makes it an ideal choice for a wide range of low voltage power supply applications.

Overall, the SK110B M4G is a reliable and efficient diode rectifier that is well suited for a variety of applications. From rectifying AC-DC power supplies to providing protection against reverse polarity, this discrete device is a great way to get the job done. With its low forward voltage, low reverse current, and fast reverse recovery time, it is easy to see why the SK110B M4G is a popular choice for many low voltage power supply designs.
