Vishay IRFR420 Series Power MOSFET, 500V Maximum Drain Source Voltage, 42W Maximum Power Dissipation - IRFR420TRPBF
This power MOSFET is a high-voltage N-channel enhancement device designed for switching and power-management roles in industrial and electronic equipment. It operates across a broad temperature range for demanding environments and is supplied in a compact surface-mount package suited to board-level assemblies.
Features and Benefits:
• 500V maximum drain-source voltage for high-voltage switching capability
• 3Ω Rds(on) enabling predictable conduction losses
• 2.4A continuous drain current for steady-state load handling
• 19nC gate charge supporting efficient switching transitions
• 42W maximum power dissipation for thermal performance budgeting
• 20V gate-source rating to accommodate strong gate-drive margins
• 3Ω Rds(on) enabling predictable conduction losses
• 2.4A continuous drain current for steady-state load handling
• 19nC gate charge supporting efficient switching transitions
• 42W maximum power dissipation for thermal performance budgeting
• 20V gate-source rating to accommodate strong gate-drive margins
Applications
• Suitable for high-voltage switch-mode power supplies
• Ideal for industrial motor-control front ends
• Used with isolated DC-DC converters in power systems
• Can be used for lamp and heater switching circuits
• Appropriate for rugged electronics operating at extreme temperatures

What mounting method should be used for reliable operation?
The package is a TO-252 surface-mount type, so standard SMT reflow processes and compatible land patterns are appropriate for PCB assembly.
What thermal limits must designers consider during layout?
The device dissipates up to 42W
copper area, thermal vias and adequate heat-sinking on the PCB are required to manage junction temperature within limits.
How does gate-drive choice affect switching performance?
A drive capable of approaching the 20V gate-source limit provides faster turn-on while the 19nC gate charge figure helps estimate required drive current and switching losses.
What environmental extremes can it endure?
It is specified to operate from -55°C to 150°C, allowing use in applications with wide ambient and junction temperature swings.
