| Market Reality | The IRF820/830/840 family is the 500V TO-220 workhorse line of off-line SMPS repair, electronic ballasts and the primary-side switching of a generation of power supplies: same 500V body, same ±20V gates, three current classes - 2.5A at 3 ohms, 4.5A at 1.5 ohms, 8A at 0.85 ohms - plus insulated FullPak variants that trade current for a plastic tab. The substitutions inside the ladder follow one arithmetic (up is free after a gate-charge check, down costs conduction loss), and the drawer trap lives one part number away: the IRFZ44N that sits next to them in every TO-220 bin is a 55-VOLT part from the low-voltage world, and the wrong grab turns a mains supply repair into a fireworks display. | The IRF820/830/840 family is the 500V TO-220 workhorse line of off-line SMPS repair, electronic ballasts and the primary-side switching of a generation of power supplies: same 500V body, same ±20V gates, three current classes - 2.5A at 3 ohms, 4.5A at 1.5 ohms, 8A at 0.85 ohms - plus insulated FullPak variants that trade current for a plastic tab.
