Pin No. Pin Name Description 1 Drain (D) Drain pin - The high-voltage output terminal of the MOSFET. This pin is connected to the load in the circuit. 2 Source (S) Source pin - This pin is connected to the ground or the return path of the circuit. 3 Gate (G) Gate pin - This controls the switching behavior of the MOSFET. A voltage applied to this pin determines whether the MOSFET is in an "on" or "off" state. Detailed Explanation: Drain (D): This is the output terminal of the MOSFET where the voltage is applied. It is typically connected to the high-voltage part of the circuit, such as the drain of a transformer or an inductive load. Source (S): This pin is the reference point of the MOSFET, which in most cases is the ground or negative terminal of the circuit. The current flows from the drain to the source. Gate (G): The gate controls the conduction of the MOSFET. By applying a voltage to the gate, the MOSFET can be turned "on" (allowing current to flow) or "off" (no current flow).Circuit Principles:
The SPP20N60C3 is an N-channel power MOSFET. Here’s a simplified working principle:
When the gate-to-source voltage (V_GS) exceeds a certain threshold, the MOSFET conducts, and current flows from the drain to the source. If V_GS is below the threshold, the MOSFET is "off," and no current can flow. The SPP20N60C3 is typically used in high-voltage switching applications, including power supplies and motor drivers.FAQ Section (20 Common Questions):
