Infineon HEXFET Series MOSFET, 40V Maximum Drain-Source Voltage, 159A Maximum Continuous Drain Current - IRFH7440TRPBF


This MOSFET is an enhancement-mode N-channel power transistor designed for high-current switching in surface-mounted applications. It operates across a broad temperature range and conforms to RoHS requirements, making it suitable for environments where compact, low-resistance switching is required without automotive certification constraints.

Features and Benefits:


• 2.4mΩ Rds(on) lowers conduction losses
• 104W Pd enables sustained power handling
• 159A continuous current supports heavy loads
• 92 nC gate charge balances drive speed and control
• 20V Vgs max provides gate overvoltage protection

Applications


• Suitable for high-current DC power stages
• Ideal for switch-mode power supplies
• Used with Compact thermal management systems
• Can be used for motor-drive inverter legs
• Used for synchronous rectification in converters

What mounting style does it require?


It is supplied in a PQFN package intended for surface-mount assembly.

What thermal range can it withstand during operation?


It is rated to function from -55°C up to 150°C.

How does its forward voltage affect efficiency?


Its forward voltage of 0.9V reduces voltage drop during conduction, affecting overall system losses.

Is it suitable for automotive-qualified designs?


It is not qualified to automotive standards and should not be selected where automotive certification is required.
