Infineon Technologies IRF1010NPBF

Overview

IRF1010NPBF from Infineon Technologies (formerly International Rectifier) is a 55V, 85A N-channel enhancement-mode HEXFET® Power MOSFET in TO-220AB package, featuring 11mΩ R_DS(on) at V_GS = 10V, 175°C max junction temperature, and fully avalanche-rated operation. It serves as a high-current, low-loss main switch in DC-DC converters, motor drives, and UPS inverters.

For engineers reviewing the IRF1010NPBF datasheet, IRF1010NPBF pinout, IRF1010NPBF application, or IRF1010NPBF equivalent, key selection criteria include its 120nC total gate charge, 41nC Miller charge, 69ns reverse recovery time, and thermal resistance of 0.85°C/W junction-to-case - critical for thermal design and switching loss estimation in high-power industrial systems.

Technical Context

This MOSFET employs advanced planar HEXFET processing to achieve ultra-low on-resistance per die area while maintaining rugged unclamped inductive switching (UIS) capability. Its body diode exhibits 1.3V forward voltage at 43A and 220nC reverse recovery charge, enabling reliable freewheeling in hard-switched topologies.

The device supports fast switching with 13ns turn-on delay, 76ns rise time, and 39ns turn-off delay under standard test conditions (V_DD = 28V, I_D = 43A, R_G = 3.6Ω), and is characterized for linear derating (1.2W/°C) above 25°C case temperature.

Manufacturer

Infineon Technologies is a global semiconductor leader headquartered in Munich, Germany, specializing in power management, sensor, and automotive ICs with strong heritage in power discretes from its acquisition of International Rectifier in 2015.

The HEXFET® product line was originally developed by International Rectifier to deliver rugged, high-current MOSFETs for industrial motor control and power conversion - emphasizing avalanche robustness, low R_DS(on), and thermal reliability in standard packages.

FAQ

Is IRF1010NPBF suitable for synchronous rectification in high-frequency DC-DC converters?

Yes - its 69ns reverse recovery time and 220nC Q_rr enable efficient body-diode conduction during dead-time intervals up to 500kHz. However, gate drive must account for 120nC Q_g and 41nC Q_gd to minimize switching losses; external Schottky clamping is unnecessary due to full avalanche rating.

What is the maximum continuous power dissipation at 100°C case temperature?

At T_C = 100°C, linear derating applies: PD = 180W − (100 − 25) × 1.2W/°C = 90W. This assumes ideal heatsinking with R_θCS ≤ 0.5°C/W and ambient below 50°C; actual dissipation depends on measured Z_thJC transient response per Figure 11.

Does IRF1010NPBF require a gate resistor for safe operation in hard-switched circuits?

Yes - a gate resistor (typically 3.6–10Ω) is required to dampen ringing caused by gate loop inductance and prevent spurious turn-on from dv/dt coupling. The 3.6Ω value used in datasheet timing tests ensures controlled 13ns td(on) and 39ns td(off); lower values increase EMI risk without meaningful speed gain.

Can IRF1010NPBF replace older IRF1010 devices in existing designs?

Yes - IRF1010NPBF is a direct drop-in replacement for IRF1010 with identical pinout, electrical specs, and TO-220AB package. The "PbF" suffix indicates lead-free construction; thermal and switching characteristics are identical, and no layout or drive circuit changes are needed for migration.
