Working Principle

The NTLUS3A39PZTAG is a three-terminal MOSFET. The source (S) terminal acts as a current reservoir and the drain (D) terminal is the output terminal. The body or substrate of the MOSFET is electrically isolated from the source and drain terminals and is generally connected to the source terminal. The gate (G) terminal is used to control current through the device. When the gate-to-source voltage (VGS) is low, the MOSFET is OFF and no current flows through the device. When VGS is raised to the threshold voltage, current begins to flow through the channel and the device is turned ON.

The NTLUS3A39PZTAG is an enhancement mode MOSFET which requires a positive VGS to turn ON. The voltage applied to the gate terminal must remain positive relative to the source terminal. When the voltage is removed from the gate terminal, current will stop flowing through the device and it will turn off.

The NTLUS3A39PZTAG is a low RDSon MOSFET, meaning that it has a low resistance when current is flowing through the device. This is beneficial for efficiency as it allows for lower power losses. Additionally, the FET has a low gate charge, meaning that the charge required to turn the device ON is also low. This makes it easier to control the device, as the voltage applied to the gate can be controlled more precisely.

The NTLUS3A39PZTAG is rated for an operating temperature range of -55°C to +150°C and can be used in automotive and battery management applications. This makes it suitable for a wide range of applications where a low-voltage, low-power switching device is needed.
