Product details

Overview

IAUTN06S5N008GATMA1 from Infineon is an automotive-grade N-channel enhancement-mode power MOSFET in PG-HSOG-8-1 package, rated for 60 V V_DS, 0.78 mΩ R_DS(on) at V_GS = 10 V, and 504 A chip-limited continuous drain current. It supports high-current motor drives and DC-DC converters in engine control units and battery management systems.

For engineers reviewing the IAUTN06S5N008GATMA1 datasheet, IAUTN06S5N008GATMA1 pinout, IAUTN06S5N008GATMA1 application, or IAUTN06S5N008GATMA1 equivalent, key selection criteria include its AEC-Q101 qualification, 175 °C operating temperature, MSL1 reflow rating, 100% avalanche testing, and low gate charge (Q_g = 273 nC) for fast switching in high-efficiency traction inverters and 48 V mild-hybrid systems.

Technical Context

This OptiMOS™ 5 device uses trench-gate superjunction technology optimized for automotive thermal and reliability demands. Its R_DS(on) of 0.78 mΩ at 100 A/10 V and Q_gd of 54 nC enable high-frequency synchronous rectification with minimal conduction and switching losses.

The MOSFET integrates a robust body diode with t_rr = 86 ns and Q_rr = 128 nC, supporting hard-switched topologies. Thermal resistance R_thJC = 0.42 K/W ensures efficient heat transfer to the PCB copper pad under sustained 504 A load conditions.

Pinout & Package

PG-HSOG-8-1 is a thermally enhanced surface-mount package with exposed source-tab on bottom side and 8-pin layout optimized for high-current PCB routing and low-inductance gate loops.

Pin/Terminal	Circuit Role	Design Meaning
1–3, 5–7	Source	Parallel low-impedance return path; connects directly to large copper pour for thermal and current handling.
4	Gate	High-impedance control input requiring <3.5 Ω series resistance to damp ringing during fast switching.
8	Drain	Main power output terminal; electrically tied to exposed metal tab for direct heatsinking to PCB ground plane.
Tab (bottom)	Drain	Primary thermal and current path; must be soldered to ≥200 mm² 2-oz copper area for R_thJC = 0.42 K/W performance.

Key Features

Feature	Design Value

Equivalent & Alternatives

The following parts are listed as comparable options for similar automotive power switching applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
IAUTN06S5N008GATMA2	Same die and package; differs only in tape-and-reel packaging configuration (1,000 pcs vs. 2,000 pcs per reel).	No functional difference; identical electrical, thermal, and reliability specs.	Select based on production line feeder compatibility and lot-size planning.
IPB180N04S4H5ATMA1	40 V V_DS, 1.8 mΩ R_DS(on), TSDSO-8 package, lower current rating (180 A).	Suitable for 12 V/24 V subsystems but not 48 V main power rails due to voltage margin limitation.	Choose only when system bus voltage ≤32 V and thermal budget permits higher R_DS(on).

Compared with IAUTN06S5N008GATMA1, the ATMA2 variant offers identical performance in alternate packaging, while the IPB180N04S4H5ATMA1 trades voltage headroom and current capacity for smaller footprint and lower cost in lower-voltage automotive sub-systems.

FAQ

What is the maximum allowable PCB copper area for optimal thermal performance?

The PG-HSOG-8-1 package requires a minimum 200 mm² of 2-ounce copper connected to the drain tab to achieve the specified R_thJC = 0.42 K/W. Larger copper areas (≥400 mm²) with thermal vias to internal ground planes further reduce steady-state junction temperature by up to 15 °C at 504 A.

Does this MOSFET require external gate resistors in half-bridge configurations?

Yes - a 3.5 Ω non-inductive gate resistor is recommended per the datasheet's switching characterization conditions. This value damps gate loop oscillation, controls dV/dt during turn-on, and prevents unintended Miller-induced turn-on when used with high-side drivers in bridge topologies.

Is the body diode suitable for continuous freewheeling in BLDC motor drives?

Yes - the body diode is fully characterized with I_S = 504 A continuous and t_rr = 86 ns at 100 A. Its soft recovery behavior and low Q_rr minimize voltage spikes and EMI, making it suitable for unidirectional freewheeling in trapezoidal commutation without external Schottky parallel devices.

How does the 175 °C rating impact system-level derating rules?

The 175 °C maximum junction temperature allows full-rated current operation up to 125 °C ambient when mounted on a properly designed PCB. No additional derating is required below that ambient point, simplifying thermal design versus legacy 150 °C-rated MOSFETs that demand 20–30 % current reduction at 105 °C.
