Vishay IRF840 Series Power MOSFET, 500V Drain Source Voltage, 125W Power Dissipation - IRF840PBF
This power MOSFET is a high-voltage semiconductor device intended for switching and amplification in power electronics. It operates across a broad temperature span and is supplied in a through-hole TO-220AB package suited to heatsinking. The component is RoHS-compliant and employs an N-channel enhancement topology for controlling drain-source conduction in high-voltage circuits.
Features and Benefits:
• 500V drain-source rating for high-voltage applications
• 8A continuous drain current supports sustained loads
• 125W power dissipation for elevated thermal handling
• 850mΩ Rds(on) balances conduction losses and control simplicity
• 63nC total gate charge enables predictable switching control
• 20V maximum gate-source voltage allows robust gate drive
• 8A continuous drain current supports sustained loads

What ambient temperatures can it tolerate during operation?
It is specified to function from -55°C up to 150°C, allowing use in demanding thermal environments.
How should it be mounted for optimal thermal performance?
The TO-220AB through-hole format is designed for attachment to a heatsink using the tab and fastener to maximise thermal conduction.
What gate drive constraints must designers observe?
Gate-source voltage must not exceed 20V
typical gate drive circuitry should provide controlled transitions to manage the 63nC gate charge.
Are there any automotive-grade assurances for use in vehicles?
It is not listed as an automotive standard device, so designers should assess suitability before vehicle applications.
