Product Name: IRF1404 N-Channel MOSFET Transistor Color: Black and Silver Material: Plastic and Metal A MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) is a type of field-effect transistor that controls current flow by varying the width of a conductive channel using a gate voltage. Charge carriers enter through the source and exit through the drain. The gate electrode, insulated from the channel by a thin oxide layer, regulates channel conductivity. MOSFETs operate in two modes: - Depletion mode: Maximum channel conductance with zero gate voltage; conductivity decreases as gate voltage increases. - Enhancement mode: No channel exists at zero gate voltage; a conductive channel forms only when sufficient gate voltage is applied. Conductivity increases with higher gate voltage. Package Includes: 10 x IRF1404 Transistors Note: Actual product color may vary slightly due to lighting and screen settings. Dimensions are subject to a tolerance of ±1–3 cm.
