Diodes - Rectifiers - Single: MCL101C-TR3 application field and working principle

MCL101C-TR3 (also known as MCL-TR3 series) is a miniature single-phase ultrafast rectifier diode with extremely low forward voltage drop. It has been specifically designed for use in switching power supplies, power factor correction (PFC) and EMI filtering circuits, as well as various other applications with 100mA to 3A rated current. It has a soft recovery behavior and its anode-cathode voltage rating of 500 volts makes it suitable for a wide range of applications. The MCL101C-TR3 has a hermetically sealed construction, which allows it to operate at high frequencies with minimal power dissipation and improved reliability and is also RoHS complaint.

Application

The application fields of MCL101C-TR3 are quite wide. For example, it can be used in switching power supplies, power factor correction (PFC) and EMI filtering circuits, free-wheeling and snubber circuits, non-inverting and inverting converters, bridge rectifiers and soft start circuits. It is also useful in electronic cooling and DC-DC converters. In addition, it is suitable to be used in the snubbers and flyback converters, phase control, and full-bridge phase circuit.

Working Principle

MCL101C-TR3 is based on the anode-cathode (A-K) rectifier principle. This is a basic rectifier circuit, wherein a voltage source is connected across a diode bridge. The current flows in the forward direction, when the forward voltage applied across the diode bridge exceeds the reverse voltage of the bridge. When the reverse voltage exceeds the forward voltage, the current flow is stopped, and the diode goes into the off-state.

The unique feature of the MCL101C-TR3 rectifier diode is the ultrafast recovery time due to its soft recovery behavior. This enables it to quickly recover from high-voltage, low-power conditions and to start operation again as soon as the voltage reaches its operating point. This is an important feature when used in a power factor correction (PFC) circuit, since it prevents oscillations that could otherwise occur in the circuit, leading to damage to the components.

Conclusion

MCL101C-TR3 has numerous application fields and provides an excellent range of services in a variety of applications. With its soft recovery behavior and hermetic construction, it provides high reliability and minimal power dissipation. In conclusion, its unique features make it an ideal choice for rectifier applications requiring high currents and high voltages.
