Vishay IRF820 Series Power MOSFET, 500V Drain Source Voltage, 2.5A Continuous Drain Current - IRF820PBF


This power MOSFET is a high-voltage N-channel enhancement device designed for switching and amplification tasks in industrial electronics. It suits applications requiring elevated drain-source voltages and moderate continuous current, operating across a wide temperature span and mounted in a standard through-hole package for straightforward board assembly.

Features and Benefits:


• 500V drain-source rating enables high-voltage switching
• 2.5A continuous current supports moderate load handling
• 50W power dissipation allows sustained thermal performance
• 3 Ω on-resistance reduces conduction-related losses
• 24 nC typical gate charge yields predictable drive requirements
• Vgs ±20V tolerance protects gate from overvoltage events

Applications


• Suitable for SMPS primary-side switching in industrial supplies
• Ideal for linear amplifier stages requiring high-voltage transistors
• Used for motor-drive Interface circuits with moderate currents
• Can be used for high-voltage test rigs and laboratory power supplies
• Suitable for retrofit through-hole designs in control panels

What mounting approach does this device require?


It is supplied for through-hole assembly in a TO-220AB package, allowing conventional soldering and heatsinking options.

What thermal range can it tolerate during operation?


It can operate between -55 °C and 150 °C, permitting use in harsh ambient and elevated-junction scenarios.

How does gate drive impact switching behaviour?


The typical gate charge of 24 nC at rated gate voltage determines required driver current and switching-speed trade-offs.

What must be considered for power dissipation management?


With a 50W maximum dissipation, external heatsinking and mounting orientation are necessary to maintain safe junction temperatures at higher loads.

Are there specific electrical limits to observe at the gate?


The gate-source voltage must not exceed ±20V to avoid damaging the gate oxide and compromising device integrity.
