Vishay IRF840S Series Power MOSFET, 500V Drain Source Voltage, 125W Maximum Power Dissipation - IRF840SPBF
This power MOSFET is a high-voltage N-channel switching device designed for surface-mount applications in power conversion and control systems. It operates across a wide thermal range and is intended for use where robust voltage handling and moderate current capability are required, such as industrial power supplies and high-voltage switching stages.
Features and Benefits:
• 500V drain-source rating enables high-voltage switching
• 8A continuous drain current supports sustained load currents
• 125W power dissipation allows high-power handling
• 850mΩ Rds(on) reduces conduction losses at operational currents
• 63nC typical gate charge permits predictable switching performance
• 20V gate-source limit provides wide gate-drive margin
• 8A continuous drain current supports sustained load currents
• 125W power dissipation allows high-power handling
• 850mΩ Rds(on) reduces conduction losses at operational currents
• 63nC typical gate charge permits predictable switching performance
• 20V gate-source limit provides wide gate-drive margin
Applications
• Suitable for high-voltage power-supply switching stages
• Ideal for motor-drive inverter front-ends
• Used with boost-converter topologies in industrial units
• Can be used for switch-mode power-rectification modules
• Suitable for high-voltage load switching in test equipment

What mounting method is required for reliable assembly?
It is supplied in a TO-263 package configured for surface-mount PCB attachment, enabling reflow soldering and thermal connection to a PCB copper area.
How does the device perform across temperature extremes?
The junction is rated to operate from -55°C up to 150°C, allowing use in environments with wide ambient and thermal swings.
What gate-drive limitations must be observed?
Gate-source voltage must not exceed 20V to prevent device damage, so gate-drive circuitry should include appropriate clamping or level control.
Are there automotive qualifications for this part?
It is not specified as meeting automotive standards, so it should not be assumed automotive-grade for vehicle-safety applications.
