Datasheet - IRF6644TRPBF

Infineon HEXFET Series MOSFET, 100V Maximum Drain-Source Voltage, 57A Maximum Continuous Drain Current - IRF6644TRPBF

This MOSFET is an N-channel enhancement device designed for power switching and control in electronic systems. It operates over a wide temperature range and is supplied in a Compact SO-8 package for mounting on printed circuit assemblies. The device is suitable where high current handling and modest forward diode drop are required, and it meets RoHS environmental restrictions.

Features and Benefits:

• 100V voltage rating enables high-voltage switching capability
• 57A continuous current supports heavy-load applications
• 13mΩ Rds(on) reduces conduction losses during operation
• 89W power dissipation allows sustained thermal loading
• 28nC gate charge enables predictable gate-drive requirements

Applications

• Suitable for DC-DC converters in power supplies
• Ideal for synchronous rectification in switch-mode supplies
• Used with motor-drive stages requiring high current
• Can be used for high-side or low-side switching
• Suitable for intermediate-bus and power-management circuits

What is the permissible ambient operating temperature range?

It functions across a minimum of -55°C up to a maximum of 150°C.

What gate voltage limits must be observed during drive?

The gate must not exceed ±20V relative to the source to prevent damage.

How does the intrinsic diode behave in forward conduction?

The built-in diode exhibits a forward voltage of 1.3V during conduction.

What packaging should be expected for board assembly?

It arrives in an SO-8 surface-mount package suitable for standard solder assembly.
