Product details

Overview

AUIRLR3110ZTRL from Infineon Technologies is a high-current N-channel enhancement-mode MOSFET in DPAK (TO-252) package, rated for 100 V V_DS, 63 A I_D (T_C = 25°C), and 4.8 mΩ R_DS(on) at V_GS = 10 V. It delivers low conduction loss in automotive DC motor control, power conversion, and load switching applications.

For engineers reviewing the AUIRLR3110ZTRL datasheet, AUIRLR3110ZTRL pinout, AUIRLR3110ZTRL application, or AUIRLR3110ZTRL equivalent, key selection criteria include its 100 V blocking capability, 63 A continuous drain current rating, ultra-low R_DS(on), AEC-Q101 qualification, and thermally robust DPAK package for under-hood automotive use.

Technical Context

This MOSFET employs trench-gate technology to achieve low on-resistance and fast switching with controlled gate charge (Q_g = 71 nC typical). Its avalanche-rated design supports repetitive unclamped inductive switching (UIS) up to 390 mJ, enabling robust operation in relay replacement and solenoid drive circuits.

The device features integrated ESD protection (HBM > 2 kV), optimized body diode recovery (t_rr = 60 ns), and guaranteed operation from –55°C to +175°C junction temperature - meeting stringent automotive thermal and reliability requirements.

I_D (T_C = 25°C)	63 A - Enables high-power load switching without external heatsinking at moderate duty cycles.
R_DS(on) @ V_GS = 10 V	4.8 mΩ - Reduces conduction loss to ≤0.3 W at 25 A, improving system efficiency.
Q_g	71 nC - Allows fast turn-on with standard gate drivers while limiting switching losses.
UIS Energy (E_AS)	390 mJ - Withstands inductive kickback in motor commutation without failure.
T_J Range	–55°C to +175°C - Qualified for engine bay and transmission control unit environments.

Pinout & Package

Package: DPAK (TO-252), surface-mount, single-die, thermally enhanced plastic case with exposed drain pad for PCB heat sinking.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Source)	Source terminal	Low-side return path; tied to ground or common reference in high-side switch configurations.
Pin 2 (Gate)	Control input	Receives logic-level or driver signal; requires 10 V for full enhancement and minimal R_DS(on).
Pin 3 (Drain)	High-side power output	Connected to load or bus; electrically and thermally coupled to exposed metal pad on bottom of package.

Key Features

Feature	Design Value
AEC-Q101 qualified	Validated for automotive electronics per stress test requirements including HTOL, TC, HTRB, and UHAST.
Ultra-low R_DS(on)	4.8 mΩ enables <1 W conduction loss at 30 A, reducing thermal design burden in space-constrained modules.
Fast body diode recovery	t_rr = 60 ns minimizes reverse recovery loss during synchronous rectification or freewheeling.
Repetitive UIS rated	390 mJ energy handling allows reliable operation in inductive load switching without snubbers.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STL110N10F7	R_DS(on) = 5.2 mΩ @ 10 V; Q_g = 65 nC; same DPAK package.	Slightly higher conduction loss but lower gate charge improves switching efficiency at high frequencies.	Prefer for PWM-driven fans where switching loss dominates over conduction loss.
IRLR3110PBF	Same die, non-automotive grade; R_DS(on) = 4.8 mΩ; no AEC-Q101 qualification.	Limited to industrial/commercial use; not validated for automotive thermal cycling or humidity testing.	Select only for cost-sensitive non-automotive designs with identical electrical needs.

Compared with STL110N10F7 and IRLR3110PBF, AUIRLR3110ZTRL uniquely combines automotive qualification, lowest R_DS(on), and proven UIS robustness - making it optimal for safety-critical 12 V/24 V vehicle subsystems requiring zero field failures.

FAQ

Is AUIRLR3110ZTRL suitable for 48 V mild-hybrid vehicle applications?

No. While rated for 100 V V_DS, its R_DS(on) and thermal performance are optimized for 12 V and 24 V systems. For 48 V architectures, Infineon recommends OptiMOS™ 6 devices such as BSZ070N04LS, which offer lower R_DS(on) and enhanced 60 V rating with improved FOM.

What is the maximum recommended gate resistor value for driving AUIRLR3110ZTRL at 20 kHz PWM?

A 10 Ω series gate resistor is recommended to limit peak gate current and damp ringing while maintaining <100 ns turn-on delay. Higher values (>22 Ω) increase switching time and losses; lower values (<4.7 Ω) risk overshoot and driver stress without significant benefit.

Does AUIRLR3110ZTRL require a gate driver IC when controlled by a 3.3 V microcontroller?

Yes. Its threshold voltage (V_GS(th)) is 2.0–4.0 V, but full enhancement requires ≥10 V V_GS to achieve 4.8 mΩ R_DS(on). A level-shifting gate driver (e.g., TC4427 or IRS2007) is mandatory for reliable operation with 3.3 V logic.

Can AUIRLR3110ZTRL be paralleled for higher current handling?

Yes, with proper layout: matched gate resistors (≤1 Ω tolerance), symmetrical PCB traces, shared thermal plane, and individual source resistors (0.01 Ω) for current balancing. Derate total current by 15% versus sum of individual ratings due to thermal coupling.
