Vishay IRF840A Series Power MOSFET, 500V Drain Source Voltage, 125W Power Dissipation - IRF840APBF
This power MOSFET is a high-voltage N-channel enhancement device intended for switching and power-control roles in industrial electronics. It operates across a broad ambient range and is supplied in a TO-220AB through-hole package for straightforward mounting in power assemblies. The device is suitable where durable thermal margins and standard gate-drive levels are used.
Features and Benefits:
• 500V drain rating enables high-voltage switching applications
• 8A continuous drain current supports moderate load currents
• 125W power dissipation allows substantial power handling
• 850mΩ Rds(on) reduces conduction losses at low gate drive
• 38nC typical gate charge minimises switching energy
• 30V gate-source limit provides robust gate-voltage tolerance
• 8A continuous drain current supports moderate load currents
• 125W power dissipation allows substantial power handling
• 850mΩ Rds(on) reduces conduction losses at low gate drive
• 38nC typical gate charge minimises switching energy
• 30V gate-source limit provides robust gate-voltage tolerance
Applications
• Suitable for industrial high-voltage converters and inverters
• Ideal for switch-mode power supply primary switching
• Used with discrete motor-control stages requiring 8A switching
• Can be used for power-management in lab test equipment
• Suitable for replacement in compatible TO-220AB assemblies

What thermal extremes can it tolerate during operation?
The device is rated to operate from -55°C up to 150°C junction temperature, supporting use in demanding temperature environments.
What mounting and board-assembly approach is recommended?
The TO-220AB package is designed for through-hole mounting and allows direct fastening to heatsinks for improved thermal dissipation.
How does the gate-charge value affect switching design?
A 38nC gate charge determines the drive current and driver selection to achieve desired switching speeds and limits driven switching losses.
What gate-voltage constraints should be observed to avoid damage?
Gate-source voltage must not exceed 30V to prevent gate-oxide stress and ensure long-term reliability.
