Diodes - Rectifiers - Single

Diodes are anessential component in power supply design. A diode consists of two electrodes and a semiconductor material. When current is applied through the electrodes, one electrode will be positive and the other negative. This polarity makes the diode a single-directional device allowing current to only flow in one direction. Diodes are usually categorized into many types, one of which is Rectifiers - Single, which includes SR1504HR0G.

SR1504HR0G application field and working principle

The SR1504HR0G is specifically designed for high frequency switching power supply rectification, with particularly important applications in Offline LLC resonant converter, Flyback converter and other topologies. It is a silicon epitaxial Schottky barrier rectifier in the industry-standard SMA package, offering capacitance and voltage ratings of 500V and 1.2A. Its low reverse leakage current and high surge capability make it ideal for high efficiency, low power consumption converters.

When operated in high frequency switching applications, SR1504HR0G is even more effective as it has very low conduction losses, thanks to its low forward voltage drop and low reverse-recovery time. This enables time-saving in the rectification process. SR1504HR0G is capable of working with power efficiency of up to 95%, making it a valuable asset in any power supply system. Other features such as low self-VF and low thermal resistance aid in both reliable operation and increased overall power efficiency.

The working principle of SR1504HR0G is relatively simple. When a positive voltage source is connected to anode A and cathode C is connected to a negative voltage source, voltage will be applied across the semiconductor junction. This will open up charge carriers and allow only electrons to move to the anode. The electrons then combine and create a current. This current can only flow in one single direction, from the anode and to the cathode.

Other than the rectification process, SR1504HR0G can also be used as a voltage regulator. When a resistor is connected in series with the diode, it resists the flow of current and regulates the output voltage at a particular level. This feature is beneficial in applications where the input voltage is unknown or varying, as SR1504HR0G can stabilize the voltage and ensure the proper functioning of the electronic device.

To protect it against extreme temperature and damages, SR1504HR0G is shipped in a packaging case, which gives protection against heat, moisture and other environmental factors. SR1504HR0G also passes the same testing and quality assurance as any other diode from Kemet, providing long lasting, reliable performance. The SR1504HR0G is recommended for use in power supply design for both general purpose rectification and voltage regulation.
