IXFP4N85X 850V N-Channel MOSFET for Mining PSU & DC-DC Converters

IXFP4N85X 850V N-Channel MOSFET | HiPERFET Power Transistor for Mining PSU & DC-DC Converters

The IXFP4N85X is a high-performance X-class HiPERFET™ N-channel MOSFET rated for 850V breakdown voltage and 3.5A continuous current — built specifically for the high-voltage primary-side switching used in ASIC mining power supplies, DC-DC converters, and PFC circuits. With its avalanche-rated reliability and standard TO-220 package, it slots cleanly into PSU repair workflows where high-voltage MOSFET failure is a common fault.

This HiPERFET part combines the headroom needed for 24/7 mining operation with the thermal envelope (-55°C to +150°C, 150W power dissipation) and switching characteristics (low 7nC gate charge) to keep efficiency high under sustained load. For repair benches stocking common high-voltage MOSFETs across an APW / Whatsminer PSU mix, the IXFP4N85X is a reliable line-replaceable part.

Low RDS(ON) 2.5Ω | TO-220 Package | -55°C to +150°C — Ideal for Harsh Mining Environments

• Ultra-low 2.5Ω RDS(ON) — minimises power losses across continuous mining duty cycles.
• High-temperature tolerance (-55°C to +150°C) — withstands rigorous mining-farm conditions.
• TO-220 package — industry-standard form factor for fast through-hole installation.
• 7nC low gate charge — enables faster switching and improved PSU efficiency.
• 150W power handling — robust performance for high-load mining applications.
• Avalanche-rated — reliable behaviour under transient overvoltage events.

Where the IXFP4N85X Fits in a Mining PSU

The IXFP4N85X targets the high-voltage primary side of switching power supplies — the section that handles the rectified mains DC bus before the transformer. In ASIC PSUs, MOSFET failure at this stage is a common outcome of long-term thermal stress and surge events. Replacing the failed device with a fresh HiPERFET-class part restores switching performance and avoids cascading failures in the gate-driver chain.
