Vishay IRF840S Series Power MOSFET, 500V Drain Source Voltage, 8A Maximum Continuous Drain Current - IRF840SPBF
This power MOSFET is a surface-mount N-channel device designed for switching and high-voltage applications in industrial electronics. It offers a high drain-source voltage rating and is intended for use where robust power handling and elevated temperature tolerance are required. The device suits assembly on modern boards and systems within automation and electrical equipment.
Features and Benefits:
• 500V drain-source rating enabling high-voltage switching capability • 8A continuous drain current supporting moderate current loads • 850mΩ Rds(on) minimises conduction losses in low-duty circuits • 63nC typical gate charge facilitating predictable drive requirements • 125W power dissipation allowing substantial heat handling at rated conditions • 20V maximum gate-source voltage protecting against excessive drive voltage
Applications
• Suitable for industrial motor drive front-ends requiring high voltage switching • Ideal for switch-mode power supplies handling elevated line voltages • Used for electronic ballast and lighting control in commercial installations • Can be used for power conversion stages in automation controllers • Used with thermal management systems where elevated junction temperature is expected
What mounting style does the device require on a PCB?
It is supplied in a TO-263 surface-mount package requiring a heatsink-capable PCB footprint and soldering for thermal conduction.
What temperature range can it operate within for harsh environments?
The component is specified to function down to -55°C and up to 150°C, supporting high-temperature applications.
How many electrical connections are present for circuit integration?
It has three pins for gate, drain and source connections suitable for standard MOSFET control schemes.
Is it suitable as a direct automotive-grade replacement?
Although not specified to automotive standards, its electrical ratings may match some replacement needs where automotive approvals are not mandatory.
