The GKR130/12 is a rectifier diode utilized in a wide range of applications including power conversion circuits, freewheeling and snubber circuits, and AC-to-DC rectification. In AC applications, rectifiers are typically used to shore up the existing circuit and to reduce the amount of power that is dissipated by the other components of the circuit.

The device is a single diode built on a silicon platform and is designed to handle power up to 130W with a repetitive peak reverse voltage of 12V. It operates in two discrete modes, referred to as conduction and reverse blocking. In conduction mode, the device acts as a low loss, unipolar switch with low voltage drop and low leakage currents. In blocking mode, it serves to block the current flow by impeding conduction by the forward bias.

The device is typically used in medium power diodes, such as lighting and motor control, for controlling or regulating the current or voltage in a circuit. It is suitable for high frequency operation, helping to reduce RFI, EMI, and electromagnetic interference. It is also a good choice for use in applications traditionally where a p-n junction diode was used such as rectification, motor speed control, and ripple removing. The device eliminates the need for multiple diodes to achieve the same effect.

The GKR130/12 works by creating a potential barrier (barrier voltage) between a positive and a negative terminal (anode and cathode). When a voltage is applied across the two terminals, a small amount of current can penetrate the barrier, allowing electric current to flow. As the voltage across the two terminals increases, the current through the diode also increases until it eventually reaches its full rated current capacity.

The device helps maintain the circuit’s voltage and current stability and minimizes losses due to thermal effects. The device\'s ability to minimize losses is especially advantageous in applications such as rectification, and when multiple diodes are wired in series as a bridge rectifier.

The GKR130/12 also provides other interesting features such as temperature protection, ESD (electrostatic discharge) protection, high peak reverse voltage (greater than 10V), low forward voltage drop, and thermal resistance. This makes the device well-suited for power conversion applications, motor drives, and AC to DC rectification.

Overall, the GKR130/12 is an excellent choice for applications where low losses and higher current ratings are needed. It provides excellent protection features and can withstand high peak currents up to 130W. The device is well-suited for use in medium power diode applications and for use in AC to DC rectification in applications where a p-n junction diode was traditionally used.
