1. Pin Function Specifications and Circuit Principle
Device Overview: Model: IKW75N65ES5 Type: N-channel MOSFET Voltage Rating: 650V Current Rating: 75A Package: TO-220 Technology: Trench MOSFET Pinout for TO-220 Package:The IKW75N65ES5 is packaged in a TO-220 style, which is a common package for power semiconductors. This package typically has 3 pins.
Pin Number Pin Name Pin Function Pin 1 Gate (G) The gate is the control pin. It controls the switching of the MOSFET. A positive voltage applied between the gate and the source will turn the MOSFET "ON". Pin 2 Drain (D) The drain is the main current path for the MOSFET. When the MOSFET is "ON", current flows from drain to source. Pin 3 Source (S) The source is the reference point for the gate and drain voltages. It is the return path for current when the MOSFET is conducting. Circuit Principle: When a voltage is applied to the gate (Pin 1), it creates an electric field that allows or prevents current flow between the drain and source. The MOSFET operates as a switch: when the gate-to-source voltage exceeds the threshold voltage (V_GS(th)), the device turns "ON" and current can flow from drain to source. When the voltage is below this threshold, the MOSFET is "OFF", and no current flows.2. Pin Function List (TO-220 Package)
As the model has 3 pins, they are detailed below:
Pin Number Pin Name Pin Function Pin 1 Gate (G) The Gate pin controls the operation of the MOSFET. A positive voltage at this pin compared to the source pin turns the MOSFET on, allowing current to flow between the drain and source. Pin 2 Drain (D) The Drain pin is the output side of the MOSFET. This pin carries the current from the MOSFET when it is turned on. It is the path for current flowing from source to drain when the MOSFET is in the "ON" state. Pin 3 Source (S) The Source pin is the reference pin of the MOSFET. It is the common terminal for both the gate and the drain. The current flows from the source through the device to the drain when the device is turned on.3. Frequently Asked Questions (FAQ)
