Diodes are semiconductor devices that allow current to flow through them in one direction.

The UF5403-E3/73 is a single rectifier diode specifically designed for applications involving high-speed power conversion and high frequency switching. Its low forward voltage drop and small reverse recovery time make it ideal for use in power line rectification, high-speed power conversion, and high frequency inverter circuits. This diode features an optimized current-voltage characteristic that allows it to provide superior performance in applications that require input current ranging from low to high currents.

The UF5403-E3/73 is a three-terminal diode, constructed with an anode, cathode and an additional gate terminal. The gate terminal is typically used in applications where instantaneous control of the diode is required. The anode and cathode act as the two conducting terminals for the device, with the anode being the positive side and the cathode being the negative side. The current flow direction is determined by the applied voltage, with current flowing from the anode to the cathode when a positive voltage is applied. The diode exhibits a relatively low reverse recovery time, allowing it to be used efficiently in high frequency inverter circuits.

The UF5403-E3/73 has a maximum current rating of 4A, is RoHS compliant, and has an operating temperature range of -55°C to +125°C. It is available in a TO-220 package and its dimensions are 2.4mm x 10mm x 10mm. The maximum allowable power dissipation is 4W.

The working principle of the UF5403-E3/73 is relatively simple: when a positive voltage is applied to the anode, current will flow from the anode to the cathode. This will cause the diode to become “forward-biased” and create a circuit. When the voltage drops below a certain threshold, the diode will become “reverse-biased”, meaning current will be prevented from flowing in the opposite direction. This principle of operation is the same across all types of diodes, although each particular diode will have different maximum ratings.

The UF5403-E3/73 is an ideal component for applications in power line rectification, high-speed power conversion, and high frequency inverter circuits. Its low forward voltage drop and small reverse recovery time make it suitable for use in a variety of applications. The diode can be used in circuits that require input current ranging from low to high currents, with a maximum current rating of 4A. Its small size and wide temperature range make it an ideal choice for use in a variety of circuits and applications.
