Vishay IRF840 Series Power MOSFET, 500V Drain Source Voltage, 8A Continuous Drain Current - IRF840PBF
This power MOSFET is a high-voltage N-channel transistor designed for switching and power-handling roles in industrial and electronic systems. It operates over a wide ambient range and is supplied in a through-hole TO-220 package for straightforward mounting and heatsinking in control assemblies.
Features and Benefits:
• 500V drain voltage supports high-voltage switching applications
• 8 A continuous drain current enables substantial load drive
• 125W power dissipation allows sustained thermal loading
• 850 mΩ RDS(on) reduces conduction losses under load
• 63 nC typical gate charge offers predictable switching behaviour
• 20V maximum gate-source rating protects the gate from overdrive
• 8 A continuous drain current enables substantial load drive
• 125W power dissipation allows sustained thermal loading
• 850 mΩ RDS(on) reduces conduction losses under load
• 63 nC typical gate charge offers predictable switching behaviour
• 20V maximum gate-source rating protects the gate from overdrive
Applications
• Suitable for high-voltage switch-mode power supplies
• Ideal for industrial motor control stages
• Used for load switching in power distribution modules
• Can be used for laboratory high-voltage test rigs
• Suitable for discrete amplifier and converter circuits

What ambient temperature range can it tolerate in operation?
It operates between -55 °C and 150 °C, allowing use in harsh thermal environments and elevated junction scenarios.
How is it mounted and cooled in a system?
It is supplied in a TO-220AB through-hole package enabling bolted heatsink attachment for efficient thermal management.
What gate drive constraints should designers observe?
Gate drive must remain within ±20V to avoid exceeding the maximum gate-source rating and to preserve device integrity.
How does switching performance relate to gate charge?
The typical 63 nC gate charge gives designers a basis on which to calculate driver current and switching transition times for specified drive voltages.
