Product details

Overview

AUIRFR1018E from Infineon is an automotive-grade N-channel enhancement-mode HEXFET® Power MOSFET in D-Pak (TO-252AA) package, designed for high-efficiency DC-DC conversion and motor control in engine management and body electronics. It delivers 7.1 mΩ typical R_DS(on) at V_GS = 10 V, 60 V V_DSS, 79 A silicon-limited continuous drain current at T_C = 25°C, and operates up to +175°C junction temperature.

For engineers reviewing the AUIRFR1018E datasheet, AUIRFR1018E pinout, AUIRFR1018E application, or AUIRFR1018E equivalent, this page provides verified electrical parameters, thermal performance data, gate charge characteristics, avalanche capability, and automotive qualification context essential for power stage design validation and BOM selection.

Technical Context

This MOSFET employs advanced trench-gate process technology to minimize conduction loss while maintaining robust switching behavior. Its low 7.1 mΩ R_DS(on) and 46 nC total gate charge enable high-frequency operation with reduced switching losses in synchronous buck converters and H-bridge drivers.

The device supports unclamped inductive switching with 11 mJ repetitive avalanche energy and 88 mJ single-pulse rating, validated under automotive thermal stress conditions. Its 21 V/ns diode recovery dv/dt and 26 ns reverse recovery time ensure stable commutation in inductive loads without external snubbers.

Equivalent & Alternatives

The following parts are listed as comparable options for similar N-channel automotive power MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STL220N6F7	60 V, 2.2 mΩ R_DS(on), 220 A ID, PowerFLAT 5x6 package	Higher current capacity but larger footprint; requires different PCB layout and thermal pad design	Select when higher peak current (>100 A) and lower R_DS(on) are prioritized over board space and legacy compatibility.
IRF1018ELPbF	60 V, 7.5 mΩ R_DS(on), same D-Pak package, non-automotive grade	Lacks AEC-Q101 qualification; not approved for safety-critical vehicle systems	Acceptable only for non-automotive industrial prototypes where qualification is not required.

Compared with STL220N6F7 and IRF1018ELPbF, AUIRFR1018E uniquely balances automotive qualification, D-Pak footprint compatibility, and 7.1 mΩ conduction loss-making it optimal for cost-sensitive, space-constrained ECU and BCM designs requiring production-grade reliability.

FAQ

What is the maximum allowable case temperature for continuous operation?

The absolute maximum case temperature is not specified directly, but continuous operation is limited by junction temperature. With R_θJC = 1.32°C/W and T_Jmax = 175°C, sustained case temperatures above ~150°C require derated current to maintain thermal margin. At T_C = 100°C, silicon-limited I_D drops to 56 A per datasheet Figure 9.

Is AUIRFR1018E suitable for synchronous rectification in DC-DC converters?

Yes-its 26 ns reverse recovery time, 21 V/ns diode dv/dt rating, and low Q_rr (24 nC) make it suitable for secondary-side synchronous rectification in 12 V input buck converters up to 500 kHz. Gate drive must be precisely timed to avoid shoot-through due to body diode conduction delay.

Does AUIRFR1018E require a gate resistor for stability?

Yes-a 5–10 Ω series gate resistor is recommended to dampen parasitic oscillation caused by trace inductance and internal gate resistance (0.73 Ω). This improves EMI performance and prevents unintended turn-on during fast dv/dt transients in high-noise automotive environments.

How does its avalanche rating compare to standard industrial MOSFETs?

AUIRFR1018E is rated for 11 mJ repetitive avalanche energy-significantly higher than most industrial MOSFETs of similar voltage class, which typically specify only single-pulse ratings. This reflects its AEC-Q101 qualification for unclamped inductive switching in automotive actuators without external protection.
