The STP45N65M5 is a N-Channel MOSFET designed for use in high power handling inverter applications such as those found in industrial inverters and motor drives. It is a single and discrete part, meaning it can be used as a single FET or in combination with other FETs to form a bridge or bridge/buck topology.

N-channel MOSFETs are power transistors that provide high-current switching and low on-resistance. They use an oxide field-effect-transistor structure in which the source, drain, and gate are connected through an oxide layer. This oxide layer allows for strong control of the electrical field generated between the source and drain, and provides the basis for efficient switches. MOSFET devices such as the STP45N65M5 are commonly used for high-current switching applications in a variety of industries, including automotive, industrial motor drives, computing, appliance motor control, office equipment, and in consumer electronics.

In a high power inverter application, the STP45N65M5 can be used in a three-level bridge topology. In this topology, the FETs are switched in pairs to either directly or indirectly control the direction of current flow through the bridge. This switching of the FETs allows for the control of the voltage and power output of the inverter.

The STP45N65M5 has a source-drain current rating of up to 45A and a maximum drain-source voltage (VDS) rating of 650V. This device is capable of handling complex power loads which require a fast switching speed. It has an RDS(on) rating of 0.84Ω, a gate-source threshold voltage (VGS) rating of 4V, and a maximum junction temperature of 150°C. The device has a low gate charge and low operational power consumption, making it an efficient MOSFET for high-current switching applications.

When used in combination with other N-Channel MOSFETs, the STP45N65M5 can be used in various configurations to facilitate various power conversions such as AC to DC, DC to DC, and AC to AC. It can also be used in circuit designs to provide multiple gate drive signals for improved noise immunity and greater control of the power output of the inverter. This device is also available in a dual package which offers a level of redundancy for increased reliability and safety.

In conclusion, the STP45N65M5 is a robust, high current N-Channel MOSFET designed for use in industrial inverters, motor drives, and other applications requiring a high power current switch. It offers excellent performance with a low on-resistance, low gate charge and low power consumption, as well as its ability to form part of a three-level bridge topology. Additionally, it is available in a dual package for greater redundancy and reliability.
