MBRF30200CT C0G

The MBRF30200CT C0G (Class 1, Grade 0) rectifier diode array is a single monolithic construction of two series avalanche diodes in a common cathode configuration, as shown in Fig. 1. This 15 Amp/200 Volt rectifier diode array is particularly suitable for use in pulse-load and other applications where high efficiency is a priority. It is capable of providing excellent surge capability while operating at junction temperatures up to +175°C.

The MBRF30200CT C0G provides a number of advantages, including: high efficiency (better than 95%), fast reverse recovery (down to 2 µs), low forward voltage drop (VDC of 2.0 Volts maximum), excellent surge performance (up to 6.5A peak current), and outstanding junction-temperature stability (no significant changes in forward voltage drop with temperature).

Due to its high efficiency and low forward voltage drop, the MBRF30200CT C0G is particularly beneficial for applications that require high levels of efficiency. Examples include Power Factor Correction (PFC) for use in AC-DC power supplies and solar systems, DC-DC conversion for hybrid electric vehicles, and AC-DC rectification in automotive body control modules.

The working principle of the MBRF30200CT C0G is fairly straightforward. When a current is passed through the diode, a bias voltage is produced, allowing the diode to go into forward conduction mode and allowing a relatively high current to flow. This current is limited by the dynamic resistance of the diode. As the current flows, the voltage drop across the diode will start to increase, resulting in a voltage loss across the diode. This voltage loss is proportional to the current: the higher the current, the higher the voltage loss.

When the current reaches a certain maximum (determined by the rating of the diode and the external circuit parameters), the diode will start to go into a reverse breakdown mode. In this mode, the bias voltage is increased due to the formation of a depletion region formed by the minority carriers in the PN junction of the diode. This region causes a parasitic potential barrier, leading to a drastic increase in the reverse leakage current and a decrease in the static resistance.

The MBRF30200CT C0G is a fast recovery, high efficiency rectifier array, suitable for applications where power efficiency and reliability are essential. Its fast recovery time enables it to handle high frequency switching applications, while its high efficiency and low forward voltage drop help reduce power loss and extend product life. In summary, the MBRF30200CT C0G is an efficient and reliable rectifier suitable for a variety of power conditioning applications.
