Product details

Overview

AUIRLS3034-7P from Infineon is an automotive-grade N-channel HEXFET® Power MOSFET in D2PAK-7L package, rated for 40 V V_DS, 1.0 mΩ typical R_DS(on) at 10 V_GS, and 240 A continuous drain current (package-limited), designed for high-current DC-DC conversion and motor control in engine bay environments.

For engineers reviewing the AUIRLS3034-7P datasheet, AUIRLS3034-7P pinout, AUIRLS3034-7P application, or AUIRLS3034-7P equivalent, key selection criteria include its 175°C junction rating, logic-level gate drive compatibility (V_GS(th) = 1.0–2.5 V), repetitive avalanche capability (E_AS = 250 mJ), ultra-low on-resistance, and D2PAK-7L thermal performance with R_θJC = 0.40 °C/W.

Technical Context

This MOSFET employs advanced silicon processing to achieve sub-1.4 mΩ R_DS(on) at 10 V_GS and supports fast switching (t_r = 590 ns, t_f = 200 ns) with low gate charge (Q_g = 120–180 nC). Its body diode features low V_SD = 1.3 V at 200 A and fast recovery (t_rr = 46–49 ns).

The device is qualified to AEC-Q101 standards, operates over −55°C to +175°C, and integrates dynamic dv/dt immunity (1.3 V/ns) and unclamped inductive switching robustness-enabling reliable operation in automotive 12 V/48 V systems with high di/dt transients.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	40 V - Maximum blocking voltage for 12 V automotive battery rail applications with margin against load dump spikes.
R_DS(on) typ.	1.0 mΩ @ V_GS = 10 V - Enables <1 W conduction loss at 200 A, critical for high-efficiency traction inverters and starter generators.
I_D (pkg-limited)	240 A @ T_C = 25°C - Package thermal limit defines maximum sustained current under board-mounted conditions.
E_AS	250 mJ - Single-pulse avalanche energy rating allows safe operation during unclamped inductive turn-off in motor drives.
R_θJC	0.40 °C/W - Low junction-to-case thermal resistance enables direct heatsink mounting for high-power density designs.
V_GS(th)	1.0–2.5 V - Logic-level gate threshold ensures full enhancement with standard 3.3 V or 5 V microcontroller outputs.
Q_g	120–180 nC - Total gate charge determines driver strength requirement; compatible with integrated gate drivers like Infineon's 2EDN series.

Pinout & Package

D2PAK-7L (TO-263-7) package with exposed drain pad for thermal and electrical connection; 7-pin configuration optimized for high-current routing and reduced parasitic inductance.

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 3, 4, 5, 6	Drain (common)	Internally paralleled drain connections tied to large copper tab - primary current path and thermal interface to heatsink.
7	Source	Main source terminal - used for current sensing and low-side switch return path; requires Kelvin connection for precision measurement.
G	Gate	Control input - isolated from power paths; requires low-inductance layout and RC snubber for dv/dt immunity.

Key Features

Feature	Design Value
175°C Junction Rating	Enables operation in under-hood environments without derating; extends lifetime in high-ambient thermal zones.
Repetitive Avalanche Rated	Supports repeated unclamped inductive switching up to T_jmax, eliminating need for external clamping diodes in brushed motor controllers.
Logic-Level Gate Drive	Operates fully enhanced with 4.5 V_GS (R_DS(on) ≤ 1.7 mΩ), reducing gate driver complexity and cost in MCU-based systems.
Ultra-Low R_DS(on)	Minimizes I²R losses in high-current paths - critical for meeting WLTP efficiency targets in 48 V mild hybrid architectures.
Dynamic dv/dt Immunity	Rated to 1.3 V/ns - suppresses false turn-on during high-speed switching in noisy automotive EMI environments.

IC Role / Device Role / Timing Role: High-side switch in interleaved synchronous buck stage, operating with tight duty cycle control.

Use Value: 175°C rating allows compact thermal design without forced air, supporting IP67-rated enclosures near engine compartments.

Electric Power Steering (EPS)

On-Board Charger (OBC) Input Stage

Use Scenario: Torque-assist motor phase leg in column-assist EPS systems subject to high vibration and thermal cycling.

IC Role / Device Role / Timing Role: Low-side switch in three-phase inverter bridge, driven by isolated gate driver with <100 ns propagation delay.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-current automotive MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STL220N4F7AG	40 V, 0.95 mΩ R_DS(on), DFN8 5x6 package, no exposed drain pad	Limited to surface-mount PCB cooling; unsuitable for bolted heatsink mounting	Select when board space is constrained and thermal load ≤ 150 W; avoid for >175°C ambient or high-reliability engine bay use.
IXTH30N40P	400 V, 30 mΩ R_DS(on), TO-247 package, non-automotive grade	Higher voltage rating but 30× higher on-resistance; not AEC-Q101 qualified	Only acceptable for non-automotive industrial prototypes; lacks required temperature range and qualification for production vehicles.

Compared with STL220N4F7AG and IXTH30N40P, AUIRLS3034-7P uniquely combines automotive qualification, D2PAK-7L bolt-down thermal interface, and sub-1.4 mΩ on-resistance - making it the only viable choice for production 48 V traction and starter-generator modules requiring long-term reliability at 175°C.

FAQ

What is the maximum continuous drain current for AUIRLS3034-7P at 100°C case temperature?

At T_C = 100°C, the silicon-limited continuous drain current is 270 A (V_GS = 10 V), per Absolute Maximum Ratings table. However, practical design must respect package thermal limits and PCB layout constraints - the 240 A rating at 25°C case temperature derates linearly at 2.5 W/°C, yielding ~175 A usable current at 100°C case with adequate heatsinking.

Does AUIRLS3034-7P support gate drive from a 3.3 V microcontroller?

Yes - its gate threshold voltage (V_GS(th)) ranges from 1.0 V to 2.5 V, and R_DS(on) is specified at 4.5 V_GS (1.2–1.7 mΩ). While full enhancement occurs at ≥4.5 V, a 3.3 V drive will yield partial conduction; for reliable operation, use a level-shifting gate driver or select a dedicated 3.3 V logic-level MOSFET variant.

How is the D2PAK-7L package different from standard D2PAK?

The D2PAK-7L adds two extra drain pins (pins 5 and 6) versus standard 3-pin D2PAK, reducing package inductance and spreading current across six parallel drain terminals. This lowers effective R_DS(on) and improves thermal coupling to the heatsink via the enlarged exposed copper pad - critical for >200 A applications where parasitic inductance causes voltage overshoot and ringing.

Is avalanche energy rating tested per pulse or cumulative?

The 250 mJ E_AS rating is a single-pulse value measured under defined test conditions (L = 0.010 mH, R_G = 25 Ω, I_AS = 220 A, T_J = 25°C). Repetitive avalanche is permitted only if junction temperature remains below 175°C - requiring thermal modeling of pulse frequency, duty cycle, and Z_thJC to ensure safe operation per Figures 13–15 in the datasheet.
