This is a 20-piece pack of IRF1404 N-channel power MOSFETs in the TO-220 package. The IRF1404 is a well-known logic-level part rated at 40V drain-source and around 162A continuous drain current, with very low on-resistance, so it suits high-current switching in motor drivers, power supplies and battery circuits. It is a bare transistor, not a module, so it needs a heatsink and proper gate drive to reach its ratings. Buyers choose it over smaller MOSFETs like the IRFZ44N when they need more current headroom; the trade-off is higher gate charge and more heat to manage.

This is a set of 20 IRF1404 MOSFET transistors. A MOSFET can work in one of two modes: depletion mode or enhancement mode.
In depletion mode, the channel conducts at its maximum when there is no voltage on the gate. Raising the gate voltage, positive or negative depending on whether the channel is P-type or N-type semiconductor material, reduces the channel's conductivity.
In enhancement mode, there is effectively no channel and the device does not conduct when there is no gate voltage. Applying voltage to the gate produces a channel, and the greater the gate voltage, the better the device conducts.
