Datasheet - IRFS4229TRLPBF

Infineon HEXFET Series MOSFET, 250V Maximum Drain Source Voltage, 45A Maximum Continuous Drain Current - IRFS4229TRLPBF

This MOSFET is a high-voltage switching transistor designed for surface-mounted power applications where robust drain handling and wide temperature operation are required. It functions as an N-channel power device suitable for fast switching and high-current circuits, operating across an extended ambient range with industry-standard approval for EIA-418.

Features and Benefits:

• 250V drain rating delivers high-voltage switching capability
• 45A continuous drain current supports heavy load currents
• 48mΩ Rds(on) reduces conduction losses under load
• 330W power dissipation enables sustained thermal handling
• 110nC gate charge allows predictable gate-drive sizing
• 1.3V forward voltage minimises diode conduction drop

Applications

• Suitable for high-voltage DC-DC converters
• Ideal for motor-drive stages in power electronics
• Used with switching regulators and power supplies
• Can be used for high-current load switching
• Suitable for surface-mount assemblies on heatsink-backed PCBs

What package and mounting style does it use?

It is supplied in a TO-263 package intended for surface mounting.

What environmental conditions can it withstand?

It is specified to operate from -55°C up to 175°C.

How much gate drive energy should designers budget for?

Designers should account for a typical gate charge of 110nC when sizing gate drivers.

Is it suitable for automotive specification applications?

It is not classified as meeting automotive-grade standards.

What maximum gate-to-source voltage must be observed?

The maximum gate-to-source voltage rating is 20V.
