Product details
Overview
AUIRF1018E from Infineon Technologies (formerly International Rectifier) is an automotive-qualified single N-channel enhancement-mode HEXFET power MOSFET rated for 60 V VBRDSS, 8.4 mΩ RDS(on) at VGS = 10 V, and 79 A continuous drain current at TC = 25°C. It is housed in a TO-220AB package and certified to AEC-Q101 for under-hood automotive power switching applications including motor control and DC-DC conversion.
For engineers reviewing the AUIRF1018E datasheet, AUIRF1018E pinout, AUIRF1018E application, or AUIRF1018E equivalent, key selection criteria include its 60 V breakdown voltage, low 8.4 mΩ on-resistance, 46 nC gate charge, thermal resistance of 1.32 °C/W (junction-to-case), and AEC-Q101 qualification for automotive reliability.
Technical Context
This MOSFET operates as a unidirectional high-current switch in hard-switched topologies. Its 60 V VBRDSS supports 48 V system rails and transient overvoltage tolerance up to 65 V. The 8.4 mΩ RDS(on) at 10 V gate drive enables efficient conduction in high-duty-cycle loads.
With 46 nC total gate charge and 12 nC gate-to-drain charge, it balances switching speed and EMI control in 20–100 kHz power stages. The 1.32 °C/W Rth(JC) allows 110 W power dissipation at TC = 25°C when mounted on a heatsink with sufficient thermal interface.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBRDSS | 60 V - Withstands 60 V drain-to-source blocking voltage, suitable for 48 V automotive systems with ISO 7637-2 pulse tolerance. |
| RDS(on) @ VGS = 10 V | 8.4 mΩ - Enables ≤0.5 W conduction loss at 8 A DC load, critical for thermally constrained engine bay modules. |
| ID @ TC = 25°C | 79 A - Maximum continuous drain current with case temperature maintained at 25°C using adequate heatsinking. |
| Qg Typ | 46.0 nC - Total gate charge determines drive strength requirement; ~2.3 A peak gate current needed for 20 ns rise time. |
| Rth(JC) | 1.32 °C/W - Junction-to-case thermal resistance; defines minimum heatsink requirement for target junction temperature. |
| PD @ TC = 25°C | 110 W - Maximum power dissipation achievable only when case is held at 25°C via active cooling or large copper area. |
Pinout & Package
TO-220AB package: three-terminal through-hole outline with isolated tab (drain-connected), standard leadform, and center-gate pin configuration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Drain (Tab) | Main current-carrying terminal, electrically connected to metal tab | Must be electrically isolated from heatsink unless circuit design requires common-drain topology; thermal path to heatsink is primary. |
| Source | Reference node for gate drive and current return path | Serves as ground reference for gate driver IC; layout must minimize source inductance to avoid switching oscillation. |
| Gate | Control electrode for channel formation | Requires low-impedance drive path; 20 V absolute maximum rating limits compatible driver selection (e.g., IR2110, UCC27531). |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive temperature cycling, humidity, and mechanical stress per JESD22-A108; supports 15-year vehicle service life. |
| Low RDS(on) (8.4 mΩ) | Reduces conduction losses by >30% vs. legacy 12 mΩ 60 V MOSFETs in 12–48 V motor drivers, improving efficiency at 10–50 A loads. |
| High ID rating (79 A) | Supports peak currents up to 120 A in pulse-width modulated motor phases without derating beyond 100°C case temperature. |
| Optimized Qgd/Qg ratio (0.26) | Improves hard-switching robustness by reducing Miller-induced shoot-through risk during high dv/dt transitions. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel 60 V power MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STL220N6F7 | RDS(on) = 3.3 mΩ @ 10 V; Qg = 105 nC; TO-220FP package (isolated tab) | Higher conduction efficiency but slower switching; better suited for low-frequency, high-current linear regulation. | Select when lowest possible I²R loss dominates over switching loss and gate drive capability permits higher Qg. |
| IXTH76N60L2 | RDS(on) = 12.5 mΩ @ 10 V; Qg = 32 nC; TO-247AC package; 600 V rating | Lower gate charge improves EMI profile but higher RDS(on) increases conduction loss; rated for 600 V, not automotive qualified. | Select only for non-automotive 48 V systems where AEC-Q101 is not required and lower gate drive demand is prioritized. |
Compared with STL220N6F7 and IXTH76N60L2, AUIRF1018E offers the optimal balance of low RDS(on), moderate Qg, and full AEC-Q101 compliance-making it uniquely suitable for cost-sensitive, thermally constrained automotive switching applications requiring production-grade reliability.

FAQ
Is AUIRF1018E pin-compatible with standard TO-220AB MOSFETs?
Yes, AUIRF1018E uses the industry-standard TO-220AB outline with Drain–Gate–Source pin order (viewed from front, leads down). Its pinout matches IRFZ44N, STP60NF06, and other common TO-220AB N-channel MOSFETs, enabling direct PCB footprint reuse in automotive redesigns.
What is the maximum safe operating junction temperature for AUIRF1018E?
The absolute maximum junction temperature is 175°C per the AEC-Q101 stress test conditions. For reliable long-term operation in automotive environments, design should limit TJ to ≤150°C using thermal modeling that accounts for Rth(JC) = 1.32 °C/W and actual heatsink Rth(CA).
Does AUIRF1018E require a gate resistor for automotive EMI compliance?
Yes-a 10–22 Ω gate resistor is recommended to dampen ringing caused by PCB trace inductance and MOSFET output capacitance. This controls dv/dt during switching and meets CISPR 25 Class 5 radiated emissions limits for powertrain modules.
Can AUIRF1018E be used in parallel configurations?
Yes, but only with matched devices and symmetrical PCB layout. Its positive temperature coefficient of RDS(on) enables current sharing above 100°C; however, gate drive skew must be ≤5 ns and source inductance balanced to prevent dynamic imbalance at high di/dt.
