Product details

Overview

AUIRFSL4010 from Infineon is an automotive-grade N-channel enhancement-mode HEXFET® Power MOSFET in TO-262 (I²PAK) package, rated for 100 V V_BRDSS, 3.9 mΩ typ. R_DS(on) at V_GS = 10 V and I_D = 106 A, 175°C maximum junction temperature, and qualified to AEC-Q101. It serves as a high-current main switch in 12 V/24 V automotive powertrain and body control modules.

For engineers reviewing the AUIRFSL4010 datasheet, AUIRFSL4010 pinout, AUIRFSL4010 application, or AUIRFSL4010 equivalent, key selection criteria include its 180 A continuous drain current at T_C = 25°C, 318 mJ single-pulse avalanche energy, 143 nC total gate charge, and TO-262 thermal resistance of 0.40°C/W (junction-to-case).

Technical Context

This MOSFET employs Infineon's advanced planar HEXFET process optimized for low R_DS(on)/area and robust unclamped inductive switching. Its gate threshold voltage (2.0–4.0 V) enables compatibility with standard 10 V gate drivers, while the 175°C operating temperature supports under-hood deployment without derating in high-ambient environments.

The device integrates a fast-recovery body diode with t_rr = 72 ns (T_J = 25°C), Q_rr = 210 nC, and dv/dt capability up to 31 V/ns - enabling efficient synchronous rectification and hard-switched DC-DC topologies in automotive ADAS and EPS systems.

Key Specifications

Parameter	Value and Actual Design Meaning
V_BRDSS	100 V - Withstands 100 V drain-source blocking voltage before avalanche onset; suitable for 24 V nominal battery systems with load dump transients.
R_DS(on) typ.	3.9 mΩ @ V_GS = 10 V, I_D = 106 A - Enables <1 W conduction loss at 180 A, critical for high-efficiency motor drive inverters.
I_D cont. @ T_C = 25°C	180 A - Supports high-power solenoid actuation and HVAC blower control without external heatsink in compact layouts.
E_AS	318 mJ - Specifies single-pulse avalanche energy limit; allows safe operation during inductive turn-off in relay driver and fuel injector circuits.
Q_g max.	215 nC - Determines gate driver strength requirement; necessitates ≥2 A peak sourcing/sinking capability for 50 ns switching transitions.
R_θJC	0.40 °C/W - Confirms direct thermal path from die to case; enables precise junction temperature estimation using case temperature measurement.
t_r/t_f	86 ns / 77 ns - Fast switching reduces switching losses in 20–100 kHz PWM applications like electric power steering (EPS) motor controllers.

Pinout & Package

TO-262 (I²PAK) package with isolated mounting tab. Three terminals: Gate (G), Drain (D), Source (S). Case is electrically connected to Drain.

Pin/Terminal	Circuit Role	Design Meaning
G	Control input	Receives gate drive signal; requires 10 V for full enhancement; internal R_G = 2.0 Ω limits dV/dt-induced ringing.
D	High-side power path	Connected to load supply rail; shares thermal interface with package base; must be routed for minimal inductance in high-di/dt paths.
S	Power return reference	Source node ties to system ground or low-side switch; forms common reference for gate drive and current sensing.

Key Features

Feature	Design Value
Automotive qualification	AEC-Q101 qualified for engine bay use; validated across -55°C to +175°C ambient with zero defects in HTOL and TC testing.
Ultra-low on-resistance	3.9 mΩ typ. R_DS(on) reduces conduction loss by >35% vs. legacy 100 V MOSFETs, directly improving system efficiency in 48 V mild-hybrid architectures.
Repetitive avalanche rating	Rated for repetitive avalanche events up to T_Jmax; eliminates need for external snubbers in inductive load switching (e.g., fuel injectors, ABS solenoids).
Fast body diode recovery	t_rr = 72 ns and Q_rr = 210 nC enable clean commutation in bidirectional DC-DC converters used in vehicle-to-load (V2L) inverters.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-current automotive MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STL220N10F7	100 V, 2.2 mΩ typ. R_DS(on), TO-220FP package, 175°C rating, but lower I_D = 120 A @ T_C = 25°C	Smaller package footprint; higher R_θJA limits power density in high-ambient environments	Select when board space is constrained and peak current ≤120 A; verify thermal margin with PCB copper area.
IPB180N10N3 G	100 V, 1.8 mΩ typ. R_DS(on), TO-263 (D2PAK), 175°C, but non-AEC-Q101 qualified	Lacks automotive qualification; not approved for safety-critical powertrain functions per ISO 26262	Acceptable only for non-safety body electronics; requires full requalification for ECU integration.

Compared with STL220N10F7 and IPB180N10N3 G, AUIRFSL4010 delivers optimal balance of 180 A current handling, AEC-Q101 compliance, and TO-262 thermal performance - making it the preferred choice for production-grade EPS and fuel injection systems where reliability and regulatory approval are mandatory.

FAQ

What is the maximum continuous drain current for AUIRFSL4010 at 100°C case temperature?

The maximum continuous drain current is 127 A at T_C = 100°C and V_GS = 10 V, as specified in the Absolute Maximum Ratings table. This reflects thermal derating due to reduced heat dissipation capacity at elevated case temperatures, and must be verified against actual PCB layout and heatsink performance.

Does AUIRFSL4010 have a built-in body diode, and what are its key recovery parameters?

Yes, AUIRFSL4010 integrates a monolithic p-n junction body diode. Key recovery parameters include reverse recovery time t_rr = 72 ns (T_J = 25°C), Q_rr = 210 nC, and peak reverse recovery current I_RRM = 5.3 A - all measured at V_DD = 85 V, I_F = 106 A, and di/dt = 100 A/µs.

Can AUIRFSL4010 be used in parallel configurations, and what layout considerations apply?

Yes, AUIRFSL4010 supports paralleling for higher current capacity. Critical layout requirements include matched gate trace lengths (<5 mm difference), Kelvin source connections to minimize current imbalance, and symmetrical thermal mounting to ensure uniform junction temperature rise across devices.

What is the gate threshold voltage range, and how does it vary with temperature?

The gate threshold voltage V_GS(th) ranges from 2.0 V to 4.0 V at T_J = 25°C, with a positive temperature coefficient of ~0.1 V/100°C. At 175°C, typical V_GS(th) increases to ~3.2 V, ensuring enhanced short-circuit immunity during overtemperature events.
