Product details

Overview

IAUC64N08S5L075ATMA1 from Infineon Technologies is an N-channel enhancement-mode logic-level OptiMOS™-5 power MOSFET rated for 80 V V_DS, 7.5 mΩ R_DS(on) at V_GS = 10 V, and 64 A continuous drain current at T_C = 25 °C. It operates up to 175 °C junction temperature, features 100% avalanche testing, and is qualified for automotive powertrain and body electronics.

For engineers reviewing the IAUC64N08S5L075ATMA1 datasheet, IAUC64N08S5L075ATMA1 pinout, IAUC64N08S5L075ATMA1 application, or IAUC64N08S5L075ATMA1 equivalent, key selection criteria include its 7.5 mΩ on-resistance at 10 V gate drive, 256 A pulsed drain capability, MSL1 reflow rating, and integrated avalanche ruggedness for high-reliability 12 V/24 V automotive switching.

Technical Context

This MOSFET uses trench-based silicon technology optimized for low conduction and switching losses in high-current DC-DC converters and motor control stages. Its gate threshold voltage (1.2–2.0 V) enables direct logic-level drive from microcontrollers, while its 2.0 K/W R_thJC supports high-power density thermal design on 2s2p PCB layouts.

The device integrates a robust body diode with 36 ns reverse recovery time and 29 nC Q_rr, making it suitable for synchronous rectification and freewheeling in bidirectional power stages. Its 2106 pF C_iss and 338 pF C_oss support stable operation under fast-switching conditions up to several hundred kHz.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	80 V - Maximum blocking voltage for 12 V/24 V automotive battery systems with load dump margin.
R_DS(on) max	7.5 mΩ at V_GS = 10 V - Enables ≤4.8 W conduction loss at 64 A DC, critical for high-efficiency power distribution units.
I_D continuous	64 A at T_C = 25 °C - Supports high-current solenoid drivers and electric power steering pre-drivers without external heatsinking.
E_AS	56 mJ - Confirmed single-pulse avalanche energy allows safe inductive turn-off in relay and motor coil circuits.
R_thJC	2.0 K/W - Enables direct thermal coupling to copper planes or heatsinks for compact 75 W power dissipation handling.
Q_g total	37 nC - Determines gate driver strength requirement; compatible with standard automotive gate drivers (e.g., BTS7xx series).
t_r/t_f	2 ns / 8 ns - Supports >500 kHz switching in DC-DC converters with minimal switching loss trade-off.

Pinout & Package

PG-TDSON-8-33 is a thermally enhanced 8-pin exposed-pad surface-mount package with dual-side cooling capability. The exposed drain pad occupies 75% of the bottom footprint and must be soldered to a large copper thermal plane for optimal R_thJC.

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 3, 4, 5, 6, 7, 8 (Drain)	Power Drain Terminal	All top-side pins and full bottom pad are internally connected to drain - requires full-solder thermal pad for rated 75 W dissipation.
Source (pins 1–3)	Source Connection	Pins 1–3 are source terminals; used for Kelvin sensing or low-inductance source return in high-di/dt applications.
Gate (pin 4)	Control Input	Single gate input with 1.2 Ω internal gate resistance - limits dV/dt during switching and reduces EMI risk.

Key Features

Feature	Design Value
Logic-level gate drive	V_GS(th) = 1.2–2.0 V - Eliminates need for gate driver ICs in 3.3 V/5 V MCU-controlled loads like HVAC actuators.
100% avalanche tested	Single-pulse E_AS = 56 mJ - Guarantees ruggedness against inductive kickback in starter relays and fuel pump drivers.
MSL1 reflow rating	Peak reflow ≤260 °C - Ensures compatibility with standard lead-free SMT assembly lines without moisture sensitivity concerns.
Automotive qualification	AEC-Q101 qualified - Validated for engine bay environments including 175 °C continuous operation and thermal cycling.
Green product	RoHS-compliant, halogen-free - Meets EU ELV and OEM sustainability requirements for vehicle production.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STL220N6F7AG	60 V V_DS, 2.2 mΩ R_DS(on) at 10 V, 220 A I_D - higher current, lower voltage rating	Better suited for 48 V mild-hybrid systems; insufficient for 80 V load-dump transients in 12 V systems	Select only if system maximum V_DS stress remains <65 V and higher current headroom is required.
IPB180N08N5L-03	80 V V_DS, 3.0 mΩ R_DS(on) at 10 V, 180 A I_D - lower R_DS(on), larger die, higher cost	Targeted at premium powertrain modules where thermal margin is critical; overqualified for BCM-level loads	Choose when board space allows TO-263-7 package and thermal budget demands sub-3 mΩ conduction loss.

Compared with STL220N6F7AG and IPB180N08N5L-03, IAUC64N08S5L075ATMA1 delivers optimal balance of 80 V robustness, 7.5 mΩ on-resistance, and PG-TDSON-8-33 compactness for mainstream 12 V automotive modules where cost, size, and AEC-Q101 compliance are jointly constrained.

FAQ

Is IAUC64N08S5L075ATMA1 AEC-Q101 qualified?

Yes, IAUC64N08S5L075ATMA1 is fully AEC-Q101 qualified for automotive applications. It undergoes stress testing including high-temperature operating life (HTOL), temperature cycling, and unbiased highly accelerated stress testing (uHAST) per AEC-Q101 Rev D standards, with full qualification data available in Infineon's official release documentation.

What is the maximum PCB copper area required for thermal performance?

For rated 75 W power dissipation at T_C = 25 °C, the PG-TDSON-8-33 package requires ≥400 mm² of 2-oz copper on both top and bottom layers, connected via ≥8 thermal vias (0.3 mm diameter) under the exposed drain pad. JEDEC-standard 2s2p FR4 layout achieves R_thJA = 24.6 K/W with this configuration.

Can this MOSFET replace older OptiMOS™-3 or -4 devices in existing designs?

Yes, IAUC64N08S5L075ATMA1 is a direct drop-in replacement for IAUC64N08S4L075 and IAUC64N08S3L075 in most cases. It maintains identical pinout, package outline, and gate threshold range while improving R_DS(on) by up to 15% and reducing Q_g by ~10%, enabling lower switching losses without layout changes.

Does the body diode support synchronous rectification in buck converters?

Yes, the integrated body diode has t_rr = 36 ns and Q_rr = 29 nC at T_j = 25 °C, enabling use in synchronous buck topologies up to 300 kHz. For optimal efficiency, pair with a controller featuring adaptive dead-time control to minimize shoot-through and reverse recovery losses.
