Working principle

The MBRF2050CTHE3/45 device consists of interconnected P-channel and N-channel enhancement mode silicon MOSFETs with a Schottky rectifier which allows for use as a low voltage, low forward voltage device. The device is especially suitable for applications with low voltage and high speed requirements in a high frequency, moderate power environment.

The integrated P-channel MOSFET acts as a switch. This switch is triggered by the gate when the output voltage is lower than the reference voltage. The integrated Schottky diode prevents current from being reversely directed to the gate, thus ensuring that the transistor switch is not damaged by excessive gate current.

The N-channel MOSFET acts as an output buffer, providing short circuit protection and ESD protection. The P-channel and N-channel MOSFETs are interconnected in the device with a depletion mode gate resistor which allows for safe operation at low voltages. The MBRF2050CTHE3/45 also has diodes for reverse conduction in the drain and source connections.
