IAUC100N04S6N022ATMA1 Overview
A power MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) is a voltage-controlled three-terminal semiconductor switch used to efficiently route or switch high currents at high speeds. MOSFETs sit within the broader transistor hierarchy (MOSFET -> transistor -> discrete semiconductor) and within Infineon's portfolio they belong to the OptiMOS 6 product line, which optimizes the figure-of-merit R_DS(on) x Q_g to deliver lower conduction and switching losses than prior generations. The PG-TDSON-8 package provides a low-inductance leadless footprint suitable for high-frequency switching converters and motor drives.
Key specifications of the IAUC100N04S6N022 include a maximum drain-source voltage V_DSS of 40 V, a typical on-state resistance R_DS(on) of 2.2 mOhm at V_GS = 10 V, and 100 A continuous drain current at case temperature. The S6 die variant indicates Infineon's latest silicon revision, delivering improved switching performance and lower gate charge compared to legacy S5 parts. Its AEC-Q100 automotive qualification makes it directly suited to 12 V and 24 V automotive subsystems where reliability and ruggedness are mandatory.
Typical applications include 12 V automotive brushed and brushless DC motor drives, electronic power steering (EPS), electric water/oil pumps, transmission control units (TCU), body electronics modules, and DC-DC converter high-side/low-side switches. The 2.2 mOhm R_DS(on) minimizes conduction loss in high-current paths, while the low Q_g reduces driver losses.
When designing with this MOSFET, ensure the gate driver supplies at least 10 V V_GS for full enhancement and that PCB copper area is sized to keep the junction temperature within the -55C to +175C operating range under worst-case load. The drain tab is electrically connected to the drain terminal and must be soldered to a sufficiently large copper pour for thermal dissipation.

Typical Applications
IAUC100N04S6N022ATMA1 is suitable for 6 applications: Automotive 12V Brushed DC Motor Drive, Electronic Power Steering (EPS) System, Automotive Electric Water/Oil Pump Drive, 12V to 48V DC-DC Boost Converter (Automotive), Transmission Control Unit (TCU) Solenoid Drive, Industrial 24V Brushless DC (BLDC) Motor Drive.
Automotive 12V Brushed DC Motor Drive
The IAUC100N04S6N022ATMA1 is well matched to 12 V brushed DC motor drives for automotive body and chassis loads such as window lift, seat adjust, sunroof, and wiper motors. Its 100 A continuous drain current at Tc and 2.2 mOhm R_DS(on) at V_GS=10 V deliver low conduction loss on the high-side or low-side switch, while the AEC-Q100 qualification ensures operation across -40C to +125C ambient automotive temperature profiles. Placed between the 12 V battery rail and the motor winding with a gate driver supplying 10 V enhancement, the IAUC100N04S6N022 keeps I^2R dissipation low enough to avoid external heatsinking at 30-50 A RMS typical motor currents. Compared to relay-based solutions, the solid-state switching provides silent operation, longer mechanical life, and PWM speed control capability, while the 40 V V_DSS rating gives adequate transient margin against 24 V jump-start and inductive kick events.
Recommended
Electronic Power Steering (EPS) System
The IAUC100N04S6N022ATMA1 fits the high-current PWM stages of 12 V electronic power steering (EPS) motor inverters where 40-80 A peak currents are common. Its 2.2 mOhm R_DS(on) and 100 A continuous rating provide the headroom needed for steering-assist torque transients without thermal shutdown, while the AEC-Q100 qualification satisfies the ISO 26262 functional-safety sourcing requirements for chassis-domain electronics. Used as a synchronous rectifier on the low-side of the buck stage or as the main inverter switch in a three-phase bridge, the IAUC100N04S6N022 reduces switching and conduction loss versus legacy OptiMOS-5 devices, directly improving EPS efficiency and reducing battery drain on stop-start vehicles. The PG-TDSON-8 footprint also enables compact PCB layouts inside the steering column housing.
Recommended
Automotive Electric Water/Oil Pump Drive
Electric water pumps (EWPs) and electric oil pumps (EOPs) in modern ICE/hybrid powertrains require 20-60 A continuous switching at 12 V, with strict reliability targets because mechanical failure can lead to engine damage. The IAUC100N04S6N022ATMA1's 100 A continuous current rating and 2.2 mOhm R_DS(on) deliver ample thermal margin at 30 A typical pump current, while its AEC-Q100 grade supports the -40C to +125C under-hood ambient range. Mounted as the high-side switch between the 12 V rail and the pump motor, the IAUC100N04S6N022 enables PWM speed control for variable coolant/oil flow, reducing parasitic loss compared to fixed-speed mechanical pumps. The 40 V V_DSS rating also protects against alternator load-dump transients reaching 35 V on the 12 V bus.
Recommended
12V to 48V DC-DC Boost Converter (Automotive)
In 48 V mild-hybrid automotive architectures, the IAUC100N04S6N022ATMA1 functions as the synchronous rectifier or main switch on the 12 V low-voltage side of a boost converter, where its 40 V V_DSS rating comfortably covers the 12 V rail plus transients. Its 2.2 mOhm R_DS(on) and 100 A current class support kilowatt-class power transfer at switching frequencies of 50-200 kHz, while the AEC-Q100 grade meets the automotive reliability bar for 48 V system components. The PG-TDSON-8 leadless package reduces parasitic source inductance, which improves switching loss and EMI compared to leaded DPAK alternatives. This makes the IAUC100N04S6N022 a strong fit for next-generation mild-hybrid DC-DC converters feeding the 48 V bus from the 12 V battery.
Recommended
Transmission Control Unit (TCU) Solenoid Drive
Automatic transmission control units (TCUs) drive multiple proportional solenoids for shift valves and clutch pressure, with typical peak currents of 5-15 A per channel and a total system demand of 30-50 A. The IAUC100N04S6N022ATMA1's 100 A continuous drain rating allows a single MOSFET to multiplex multiple solenoid loads or serve as a master protection switch, while the 2.2 mOhm R_DS(on) minimizes voltage drop across the switch and preserves solenoid actuation accuracy. The AEC-Q100 grade and -55C to +175C junction temperature range meet the harsh under-hood environment, where transmission oil temperatures can reach 150C. The PG-TDSON-8 leadless footprint also enables SMT assembly compatible with the high-density TCU PCBs of modern 8-10 speed transmissions.
Recommended
Industrial 24V Brushless DC (BLDC) Motor Drive
Although optimized for automotive, the IAUC100N04S6N022ATMA1's 40 V V_DSS and 100 A rating make it equally applicable to industrial 24 V BLDC motor drives in factory automation, robotics, and conveyor systems. Its 2.2 mOhm R_DS(on) at 10 V V_GS reduces I^2R loss in the inverter bridge, while the PG-TDSON-8 leadless footprint simplifies SMT assembly on high-volume automation control PCBs. Operating as a low-side switch in a three-phase inverter at 10-30 kHz PWM, the IAUC100N04S6N022 delivers high efficiency at 20-60 A RMS phase currents typical of small industrial BLDC motors. The wide -55C to +175C junction temperature range also supports operation in uncooled industrial cabinets. Note: in non-automotive designs the AEC-Q100 qualification becomes a beneficial bonus rather than a strict requirement.

Design Notes
At I_D = 50 A continuous and V_GS = 10 V, conduction loss is approximately P = I^2 * R_DS(on) = 50^2 * 0.0022 = 5.5 W. With the PG-TDSON-8 package theta_JA in the 50-60 C/W range on a 1 sq-inch copper pad (Estimated: standard JEDEC 4-layer PCB, 1 oz copper, no heatsink), junction temperature rise is approximately 5.5 W * 55 C/W = 302 C above ambient. This is above the 175 C maximum junction rating, so a larger copper pad (>=2 sq-inch) or forced airflow is required. For sustained 100 A operation, Infineon recommends 4+ sq-inch of copper on the drain tab with a thermal via array under the package. Estimated: numbers derived from I^2R and standard thermal-resistance assumptions; verify against Infineon application note TN2018-01 for production designs.
The PG-TDSON-8 drain tab is electrically connected to the drain terminal. The PCB land pattern must include a large copper pour on the drain pad, with a thermal via array (>=9 vias, 0.3 mm drill, 1 mm pitch) to inner copper layers to reduce junction-to-ambient thermal resistance. The gate and source traces should be routed as a tight differential pair to minimize gate-loop inductance; excessive loop inductance causes ringing, EMI, and potential dv/dt-induced shoot-through. Place a 100 nF ceramic bypass capacitor between V_GS and the local source return within 5 mm of the gate pin to suppress gate-rail bounce during high-di/dt switching transitions. Source pin 8 should be used as the gate-driver return to avoid source-inductance-induced V_GS degradation at high di/dt.
Do not assume the IAUC100N04S6N022 is pin-compatible with TO-220, TO-252 (DPAK), or D2PAK footprints - PG-TDSON-8 (5x6 mm) is a different, smaller leadless package requiring its own PCB land pattern. Driving the gate with less than 8 V V_GS will operate the part in the linear region, causing high dissipation and possible thermal runaway - always use a gate driver capable of 10 V enhancement. The drain tab must be soldered to the PCB for proper thermal performance; dry-solder or insufficient paste on the thermal pad will cause thermal failure at high current. Do not parallel two IAUC100N04S6N022 units without gate-source resistor balancing and matched R_DS(on) binning, or current sharing will be uneven.
