Key Features
- 150 V drain-source breakdown voltage and 171 A maximum drain current for high-power switching in motor drives and industrial converters
- Ultra-low 5.9 mΩ drain-source on-resistance (Rds-on) minimizing conduction losses and heat dissipation in high-current circuits
- 763 mJ single-pulse avalanche energy rating (Eas) providing robust protection against unclamped inductive switching events in real-world load scenarios
Applications
The IRFP4568PBF is optimized for high-current power switching applications including synchronous motor drives, DC-DC converters, and industrial power supplies operating at up to 150 V. Its extremely low 5.9 mΩ on-resistance reduces I²R conduction losses even at 171 A continuous drain current, making it well suited for high-efficiency inverter bridges and battery management systems. Power supply designers also select this device for server PSUs and solar inverters where thermal performance and rugged avalanche capability are critical.

Frequently Asked Questions
What drain-source voltage and maximum drain current does the IRFP4568PBF support?
The IRFP4568PBF is rated for a 150 V drain-source breakdown voltage and a maximum continuous drain current of 171 A, positioning it for demanding high-power motor drive, inverter, and DC-DC converter designs where both voltage headroom and high current capacity are required simultaneously.
How does the 5.9 mΩ on-resistance of IRFP4568PBF affect power loss in a motor controller?
At 5.9 mΩ Rds-on, conduction losses at 100 A of drain current are approximately 59 W (P = I² × Rds), which is significantly lower than many comparable 150 V MOSFETs in this package class, enabling smaller heatsinks and higher efficiency in 3-phase motor control bridges operating from 48 V to 100 V bus voltages.
What is the significance of the 763 mJ avalanche energy rating on IRFP4568PBF?
The 763 mJ single-pulse unclamped inductive switching (UIS) avalanche energy rating means the device can safely absorb energy spikes from inductive loads—such as motor windings or transformer leakage inductance—without entering destructive breakdown, improving circuit robustness and reducing the need for external snubber components in unclamped designs.
In what package does the IRFP4568PBF come, and what does that mean for thermal management?
The IRFP4568PBF is packaged in the TO-247AC (TO-247 3-lead) through-hole case, which provides a large exposed drain tab with low thermal resistance to a heatsink, typically in the range of 0.4°C/W junction-to-case, allowing the MOSFET to dissipate the high power levels generated at 171 A without exceeding junction temperature limits when properly heatsinked.
