IAUCN04S7N006TATMA1 Overview
What is an N-channel power MOSFET? An N-channel power MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) is a voltage-controlled switch whose drain-source channel uses electron flow as the majority carrier. It belongs to the broader category of discrete power semiconductors, which sits inside power management and motor/motion conversion. The "40 V" rating defines the maximum drain-to-source blocking voltage the device can sustain when off, and a low R_DS(on) directly reduces conduction losses in high-current paths such as automotive 12 V/24 V systems.
Key features of the IAUCN04S7N006 include 0.63 mΩ typical R_DS(on) at V_GS = 10 V, automotive-grade qualification per Infineon's automotive MOSFET line, an exposed-lead package for low thermal resistance, and compatibility with logic-level gate drive when biased at 4.5 V V_GS. The PG-LHDSO-10-3 footprint is optimized for top-side cooling with a large solderable thermal pad.
The OptiMOS 7 cell architecture uses a shielded-gate trench design that simultaneously reduces gate charge (Q_G), output charge (Q_OSS), and reverse-recovery charge (Q_RR). Compared to previous OptiMOS generations, this delivers lower switching losses at high dV/dt, allowing higher PWM frequencies in motor drives without sacrificing efficiency.
Typical applications include 12 V and 24 V automotive BLDC motor drives (EPS, water pumps, oil pumps, fan control), high-current DC-DC converter high-side and low-side switches, battery protection in 12 V/24 V Li-ion packs, and industrial solenoid drivers. The very low R_DS(on) of 0.63 mΩ makes it well-suited to continuous high-current paths where conduction loss dominates thermal budget.
When designing with this part, keep the gate-drive loop compact and use Kelvin-source connection if the package exposes one. Estimate: at 100 A continuous, conduction loss alone is approximately I²·R = 100² × 0.63 mΩ ≈ 6.3 W, so the PCB copper pour and thermal via array must be sized accordingly.

Typical Applications
IAUCN04S7N006TATMA1 is suitable for 6 applications: Automotive 12V/24V BLDC Motor Drive (EPS, Pumps, Fans), High-Current 12V/24V DC-DC Converter Power Stage, Battery Protection & Disconnect Switch, Industrial Solenoid & Relay Replacement, Hot-Swap & ORing Controller Power Switch, Power Distribution & Load Switch Module.
Automotive 12V/24V BLDC Motor Drive (EPS, Pumps, Fans)
The IAUCN04S7N006TATMA1 fits automotive BLDC inverter stages (electric power steering, water/oil pumps, radiator fans) because its 40 V V_DS rating covers the 24 V nominal bus plus ISO 7637-2 transient margin, while its 0.63 mΩ typical R_DS(on) keeps conduction loss below 6 W at 100 A continuous. The PG-LHDSO-10-3 exposed pad supports >200 W dissipation on a properly designed PCB copper pour. Placed in the inverter half-bridge switching at 20-50 kHz PWM, it adds lower switching loss than previous OptiMOS generations thanks to reduced Q_G and Q_OSS. Compared to a discrete IGBT solution, this MOSFET also enables higher PWM frequency and quieter acoustic signature.

High-Current 12V/24V DC-DC Converter Power Stage
In high-current buck or boost converter stages for 12 V/24 V automotive rails, the IAUCN04S7N006TATMA1 serves as the synchronous-rectifier or control switch. At 100 A load the 0.63 mΩ R_DS(on) translates to roughly 6.3 W conduction loss, leaving generous thermal margin in a 205 W rated package. The 40 V V_DS handles 24 V bus transients without avalanche, and the OptiMOS 7 shielded-gate trench gives low Q_OSS for reduced dead-time losses. Use the part in the synchronous-rectifier slot where the switch is on most of the time and conduction loss dominates efficiency.
Recommended
Battery Protection & Disconnect Switch
The IAUCN04S7N006TATMA1 works well as a low-side or high-side disconnect switch in 12 V/24 V battery management systems, where its 0.63 mΩ R_DS(on) minimizes voltage drop and self-heating during normal operation. The 40 V V_DS is well above the 24 V load-dump envelope, and the automotive-grade qualification matches the BMS safety requirements. Place a fuse upstream and a TVS across the battery terminals for full ISO 7637-2 compliance; the MOSFET's high 425 A current rating provides ample margin for inrush and short-circuit transients until the fuse clears.
Recommended
Industrial Solenoid & Relay Replacement
In industrial 24 V solenoid drivers replacing mechanical relays, the IAUCN04S7N006TATMA1 enables PWM current profiling (soft-start, hold-current reduction) that mechanical relays cannot provide. Its 0.63 mΩ R_DS(on) reduces I²R heating at the typical 2-5 A solenoid current to a few milliwatts per channel, and the 40 V V_DS handles 24 V flyback transients when paired with a freewheeling diode. The PG-LHDSO-10-3 surface-mount footprint supports high-density multi-channel driver boards where dozens of channels are integrated into a single PCB.
Recommended
Hot-Swap & ORing Controller Power Switch
The IAUCN04S7N006TATMA1 can be used as the main pass element in a 12 V/24 V hot-swap or ORing controller, where its 0.63 mΩ R_DS(on) keeps the steady-state voltage drop under 70 mV at 100 A. During inrush, the gate-drive circuit ramps V_GS to limit dV/dt and dI/dt, and the 40 V V_DS rating provides robust avalanche margin if a short-circuit event occurs. Use the exposed-pad copper pour to spread the heat from momentary inrush currents (typically 5-20× steady state), and verify that the gate-driver can sink enough current to turn the part off quickly during fault events.
Recommended
Power Distribution & Load Switch Module
The IAUCN04S7N006TATMA1 serves as a high-current load switch in zonal automotive power distribution modules, replacing fuses and mechanical relays with a software-controlled electronic switch. Its 0.63 mΩ R_DS(on) supports >100 A continuous current with minimal heat, while the 40 V V_DS handles 24 V bus transients and the PG-LHDSO-10-3 surface-mount footprint integrates cleanly into PCB-based PDMs. Pair the MOSFET with a dedicated high-side gate driver and current-sense amplifier to build a fully protected, diagnostic-capable smart switch.

Design Notes
Estimated: at 100 A continuous drain current, conduction loss is approximately I²·R = 100² × 0.63 mΩ ≈ 6.3 W, rising to about 27 W at 200 A. The PG-LHDSO-10-3 exposed thermal pad must be soldered to a copper pour of at least 25 × 25 mm with thermal vias to inner-layer copper; without adequate PCB cooling, the junction will exceed its rating at sustained high currents. Confirm junction temperature under worst-case ambient using the datasheet's thermal-resistance model (θ_JA on a standard JEDEC test board is the typical reference value).
Route the high-current drain and source traces on top copper layers directly into the exposed pad to minimize parasitic inductance. Use a Kelvin-source connection (separate gate-return trace tied to the source pad) to keep the gate-drive loop physically small, which reduces ringing during fast switching. Place the gate-driver within 5-10 mm of the gate pin to limit gate-loop inductance, and add a 10 Ω gate resistor plus a small ferrite bead to dampen overshoot on V_GS.
Do not exceed V_GS = ±20 V absolute maximum, even momentarily, as the gate oxide can be permanently damaged. Add a gate-source Zener or TVS clamp (typically 16-18 V) for additional protection in noisy automotive environments. Verify the in-system V_DS spike during turn-off stays below the 40 V rating by accounting for stray inductance: V_spike = L_stray × dI/dt, where dI/dt can exceed 1 kA/µs in fast-switching applications. Add a snubber or RCD clamp if measured transients approach the avalanche limit.
