Product details

Overview

AUIRFS4115-7TRL from Infineon is an automotive-grade N-channel D2PAK (TO-263AB) HEXFET® Power MOSFET with 150 V V_BR(DSS), 10.3 mΩ typical R_DS(on) at V_GS = 10 V, 99 A continuous drain current at T_C = 25°C, and 175°C maximum junction temperature - deployed in high-current DC-DC converters and motor control inverters for electric power steering and HVAC compressors.

For engineers reviewing the AUIRFS4115-7TRL datasheet, AUIRFS4115-7TRL pinout, AUIRFS4115-7TRL application, or AUIRFS4115-7TRL equivalent, key selection criteria include its 0.40 °C/W R_θJC, 77 nC total gate charge, 86 ns reverse recovery time, repetitive avalanche rating up to T_Jmax, and RoHS-compliant lead-free construction.

Technical Context

This device uses Infineon's advanced trench-gate process to achieve ultra-low on-resistance per die area while sustaining 150 V blocking capability. Its 175°C rated junction enables operation in under-hood environments without derating penalties common in commercial-grade MOSFETs.

The integrated body diode exhibits 1.3 V forward voltage at 62 A and 86 ns reverse recovery time at 25°C, supporting synchronous rectification and unclamped inductive switching. Gate drive requirements are defined by 2.3 Ω internal gate resistance and 26 nC Q_gd, enabling fast turn-off with minimal Miller-induced shoot-through risk.

Key Specifications

Parameter	Value and Actual Design Meaning
V_BR(DSS)	150 V - Sustains full battery transients in 12 V/24 V automotive systems without breakdown.
R_DS(on) typ.	10.3 mΩ @ V_GS = 10 V, I_D = 62 A - Enables <1.0 W conduction loss at 100 A, critical for thermal management in compact modules.
I_D cont.	99 A @ T_C = 25°C - Supports high-current motor phase legs and starter solenoid drivers without parallel devices.
E_AS	230 mJ - Allows safe energy absorption during unclamped inductive switching events in BLDC controllers.
Q_g	77 nC - Defines minimum gate driver current requirement (~1.5 A peak for 50 ns rise time) in high-frequency PWM stages.
R_θJC	0.40 °C/W - Enables direct heatsink mounting with predictable junction-to-case thermal path for thermal modeling.
t_rr	86 ns @ T_J = 25°C - Limits diode commutation losses in synchronous buck and half-bridge topologies.

Pinout & Package

Package: D2PAK (TO-263AB), surface-mount, single-ended heatsink tab (Drain-connected). Thermal pad soldered to PCB copper pour for low R_θJA.

Pin/Terminal	Circuit Role	Design Meaning
Tab (Backside)	Drain (D)	Primary thermal and electrical connection point; must be soldered to large copper area for heat dissipation and low-inductance return path.
Lead 1	Source (S)	Low-side reference node; connects to ground plane or shunt resistor for current sensing and gate drive return.
Lead 2	Gate (G)	High-impedance control input; requires low-inductance routing and local 10–100 nF decoupling near package.
Lead 3	Source (S)	Second source terminal for Kelvin sensing or reduced loop inductance in high-di/dt applications.

Key Features

Feature	Design Value
175°C operating junction temperature	Eliminates thermal derating in engine bay locations where ambient exceeds 105°C, enabling smaller heatsinks.
Repetitive avalanche rated to T_Jmax	Supports robust operation in inductive load switching without external snubbers or clamping circuits.
Ultra-low 10.3 mΩ R_DS(on)	Reduces conduction losses by >35% vs. legacy 150 V MOSFETs, improving efficiency in 48 V mild-hybrid systems.
Fast 73 ns rise time / 39 ns fall time	Enables >100 kHz switching in DC-DC converters while maintaining <5% switching loss contribution.
RoHS-compliant, lead-free construction	Meets automotive ELV directive and supports Pb-free reflow profiles without reliability compromise.

Applications

Electric Power Steering (EPS)

48 V Mild-Hybrid DC-DC Converter

Use Scenario: High-current H-bridge driving 3-phase brushless motor in rack-and-pinion EPS module.

IC Role / Device Role / Timing Role: Low-side and high-side switching element in 20–40 kHz PWM inverter stage.

Use Value: 175°C rating avoids thermal shutdown during sustained assist torque; 230 mJ E_AS absorbs inductive kickback during fault conditions.

Use Scenario: Primary switch in bidirectional buck-boost converter linking 12 V starter battery and 48 V Li-ion storage.

IC Role / Device Role / Timing Role: Main power switch operating at 150–250 kHz with synchronous rectification.

Use Value: 10.3 mΩ R_DS(on) limits conduction loss to <0.8 W at 100 A, enabling >96% peak efficiency at full load.

HVAC Compressor Inverter

Start-Stop System Solenoid Driver

Use Scenario: Three-phase inverter powering variable-speed scroll compressor in vehicle cabin climate control.

IC Role / Device Role / Timing Role: Phase-leg switch handling 60–120 A peak currents with 10–20 kHz carrier frequency.

Use Value: 0.40 °C/W R_θJC allows direct heatsink mounting on aluminum chassis, reducing system thermal mass by 40%.

Use Scenario: High-side driver for 12 V starter solenoid coil requiring 300 A inrush current for <50 ms.

Equivalent & Alternatives

The following parts are listed as comparable options for similar N-channel 150 V power MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STL110N10F7	100 V V_BR(DSS), 5.5 mΩ R_DS(on), TO-220FP package, 175°C rated	Lower voltage rating limits use to 12 V systems only; not suitable for 24 V/48 V transient immunity.	Select only for cost-sensitive 12 V auxiliary loads where 150 V margin is unnecessary.
IXFH110N15T2	150 V V_BR(DSS), 11.5 mΩ R_DS(on), TO-247 package, 175°C rated, 110 nC Q_g	Higher gate charge increases driver complexity; TO-247 requires larger footprint and manual assembly.	Prefer when higher avalanche energy (420 mJ) is required and board space permits through-hole mounting.

Compared with STL110N10F7 and IXFH110N15T2, AUIRFS4115-7TRL uniquely balances 150 V rating, ultra-low R_DS(on), D2PAK surface-mount compatibility, and automotive qualification - making it optimal for space-constrained, thermally demanding inverter modules requiring AEC-Q101 compliance.

FAQ

What is the maximum allowable case temperature for continuous operation?

The AUIRFS4115-7TRL supports continuous operation up to 175°C junction temperature. With a 0.40 °C/W R_θJC, the maximum case temperature depends on power dissipation: for 100 W loss, T_C must remain ≤135°C to maintain T_J ≤175°C. Derating begins above 25°C ambient per the 2.5 W/°C linear factor.

Is this MOSFET suitable for synchronous rectification in a 48 V buck converter?

Yes - its 1.3 V body diode forward voltage at 62 A and 86 ns reverse recovery time enable efficient synchronous rectification at 150–250 kHz. The low 10.3 mΩ R_DS(on) further reduces conduction loss versus external Schottky diodes, especially at high load currents.

Does AUIRFS4115-7TRL require a negative gate voltage for reliable turn-off?

No - the gate threshold voltage is specified from 3.0 V to 5.0 V, and the device is fully enhanced at V_GS = 10 V. A negative gate voltage is not required; however, applying –5 V to –10 V improves noise immunity and prevents spurious turn-on in high-dv/dt environments like motor drives.

How does the repetitive avalanche rating impact circuit protection design?

The 230 mJ single-pulse avalanche energy (E_AS) and explicit repetitive avalanche allowance up to T_Jmax mean the device can safely absorb inductive energy multiple times without external clamping. This eliminates need for TVS diodes or RCD snubbers in properly designed gate-driven inverter legs.
