Vishay IRF740 Series Power MOSFET, 400V Drain Source Voltage, 10A Continuous Drain Current - IRF740PBF


This power MOSFET is a high-voltage N-channel enhancement device designed for use in industrial switching and power-control circuits. It operates across a wide temperature range and is supplied in a through-hole TO-220AB package suitable for assemblies where robust mounting and straightforward heat-sinking are required. The device is intended for applications demanding sustained current handling and elevated voltage tolerance.

Features and Benefits:


• 400V drain-source rating for high-voltage switching applications • 10A continuous drain current to support moderate power loads • 125W power dissipation for reliable thermal performance • 550mΩ RDS(on) enabling efficient conduction in switching roles • 63nC typical gate charge to inform drive requirements • 20V maximum gate-source voltage for gate-drive margin

Applications


• Suitable for switch-mode power supply primary switching • Ideal for motor-control inverter stages in automation systems • Used for high-voltage power converters in industrial equipment • Can be used for power management in test and measurement rigs

What mounting method does the device require for heat management?


It is a through-hole component in a TO-220AB package, allowing direct attachment to heatsinks using a fastener and insulating hardware if required.

What temperature extremes can it tolerate during operation?


The device is specified to operate down to -55°C and up to 150°C, making it suitable for a wide range of environmental conditions.

What should be considered when designing the gate drive?


The maximum gate-source voltage is 20V and the typical gate charge is 63nC at VGS, so the driver must supply sufficient charge and respect the 20V limit to avoid gate overstress.

Is the device compliant with common environmental material standards?


The component conforms to RoHS directives on restricted hazardous substances.
