UF4003 R0G

The UF4003 R0G is a diode rectifier from the single diode product family, used mainly in applications requiring high power and strong reverse voltage capabilities. Designed for a wide range of rectifying tasks, this part has a large current capacity, making it suitable for circuit designs with high currents. In addition, the device has high surge capability, a reverse leakage current of only 50nA, and a noise figure of -80dBm.

The UF4003 R0G is an ideal choice for applications such as switch-mode power supplies, bridge rectifiers, DC-DC converter circuits and high-speed switching circuits. It can also be used in a flyback circuit, and is ideal for applications such as power, lighting, and motor control applications.

The UF4003 R0G has a maximum forward current rating of 40A and a pulse forward current of 101A. It also has a low forward voltage drop of 1.6V and a maximum reverse voltage of 200V. The diode is also suitable for use in low-frequency designs, with a maximum reverse recovery time of 50ns.

Working Principle:

The UF4003 R0G operates on the principle of rectification. A rectifier is an electrical device that converts alternating current (AC) into direct current (DC) by allowing current flow in one direction only. This is done by blocking current in the reverse direction, which is an effect achieved through a structure of PN junctions. In the case of the UF4003 R0G, the device is configured as a two terminal leaded package, each comprising two PN junctions. This configuration ensures that current is blocked in the reverse direction, and the desired current flow is only allowed in the forward direction.
