Product details
Overview
AUIRLR3110Z from Infineon Technologies is a 100 V, 42 A, N-channel enhancement-mode MOSFET in DPAK package with 15 mΩ RDS(on) at VGS = 10 V, optimized for high-efficiency DC-DC converters and automotive motor control circuits.
For engineers reviewing the AUIRLR3110Z datasheet, AUIRLR3110Z pinout, AUIRLR3110Z application, or AUIRLR3110Z equivalent, key selection criteria include RDS(on), Qg, thermal resistance (RthJA), avalanche ruggedness rating, and AEC-Q101 qualification status.
Technical Context
This MOSFET employs trench-gate silicon technology to achieve low conduction loss and fast switching with 38 nC total gate charge. It supports hard-switched topologies up to 200 kHz and features 100% UIS-tested avalanche capability rated at 170 mJ (TC = 25 °C).
The device integrates an integrated ESD protection diode and is specified for operation from –55 °C to +175 °C junction temperature, meeting automotive-grade reliability requirements per AEC-Q101 Rev D.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 100 V - maximum drain-source blocking voltage for 12 V/24 V automotive power rails |
| ID (continuous) | 42 A @ TC = 25 °C - continuous current handling with heatsink mounting |
| RDS(on) | 15 mΩ @ VGS = 10 V - enables <1 W conduction loss at 20 A load |
| Qg | 38 nC - determines gate drive power requirement and switching speed in PWM stages |
| RthJA | 62 K/W - thermal resistance from junction-to-ambient in standard PCB layout (1 cm² copper) |
| EAS | 170 mJ - single-pulse avalanche energy rating ensures robustness during inductive turn-off |
Pinout & Package
Package: DPAK (TO-252-3), surface-mount, single-drain tab design with exposed drain pad for thermal conduction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Source) | Source terminal | Low-side reference node; connects directly to ground plane or source return path |
| Pin 2 (Gate) | Control input | Receives PWM signal; requires 10 V drive for full enhancement and minimal RDS(on) |
| Pin 3 (Drain) | Power output node | Connected to load or inductive rail; tab is electrically tied to drain for thermal and electrical conduction |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive under-hood applications including engine control and EPS |
| 100% UIS tested | Each unit verified for unclamped inductive switching robustness up to 170 mJ |
| Low Qgd/Qg ratio | 0.29 - reduces Miller-induced shoot-through risk in half-bridge configurations |
| Fast body diode recovery | trr = 55 ns - minimizes reverse recovery loss in synchronous rectification |
Applications
| Engine Control Unit (ECU) Power Stage | Electric Power Steering (EPS) H-Bridge |
|---|---|
Use Scenario: High-current switching of fuel injector drivers and solenoid valves in gasoline/diesel ECUs. IC Role / Device Role / Timing Role: Low-side switch controlling coil energization timing with precise PWM duty cycle.

IC Role / Device Role / Timing Role: Synchronous rectifier in secondary-side FET position operating at 500 kHz. Use Value: 55 ns trr reduces reverse recovery loss by >40% vs. standard MOSFETs, improving efficiency above 92%. | Use Scenario: PWM-controlled blower motor driver in climate control systems with variable airflow demand. IC Role / Device Role / Timing Role: Low-side switch modulating motor current with 1–10 kHz PWM frequency. Use Value: 62 K/W RthJA allows 30 A continuous operation on standard 2-layer PCB without forced air cooling. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel 100 V power MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STL130N10F7 | RDS(on) = 11.5 mΩ @ 10 V; Qg = 42 nC; no AEC-Q101 certification | Not qualified for automotive safety-critical systems; suitable for industrial DC-DC only | Select when higher efficiency is prioritized over automotive qualification |
| IRLR3110PBF | Same die, non-automotive grade; RthJA = 65 K/W; no UIS testing | Limited to commercial temperature range (–55 °C to +150 °C); not for under-hood use | Acceptable for cost-sensitive consumer or industrial motor drives |
Compared with STL130N10F7 and IRLR3110PBF, the AUIRLR3110Z uniquely combines AEC-Q101 qualification, 100% UIS testing, and 175 °C max TJ, making it the only choice for production automotive power stages requiring functional safety compliance.

FAQ
What is the maximum junction temperature rating for AUIRLR3110Z?
The AUIRLR3110Z is rated for continuous operation up to +175 °C junction temperature, validated per AEC-Q101 stress test conditions including high-temperature operating life and temperature cycling. This enables deployment in under-hood environments where ambient temperatures exceed +125 °C.
Does AUIRLR3110Z require a gate resistor for automotive PWM applications?
Yes - a 10 Ω to 22 Ω series gate resistor is recommended to dampen ringing and limit peak gate current during 10 V drive transitions. This prevents overshoot beyond ±20 V absolute maximum rating and controls dV/dt-induced crosstalk in multi-MOSFET layouts.
Can AUIRLR3110Z replace IRLR3110 in existing designs?
No direct drop-in replacement: AUIRLR3110Z has identical pinout and RDS(on), but its enhanced thermal spec (175 °C TJ max vs. 150 °C) and AEC-Q101 qualification require revalidation of thermal margin and system-level reliability testing before substitution in production automotive hardware.
Is the drain tab electrically isolated in the DPAK package?
No - the exposed drain pad in the DPAK package is electrically connected to Pin 3 (Drain). It must be soldered to a dedicated drain copper pour tied to the high-side power net; isolation requires insulating thermal interface material or mechanical standoff.
