IAUT300N08S5N014ATMA1 Обзор
A power MOSFET is a voltage-controlled majority-carrier switch in which a gate-source electric field modulates the conductance of a conducting channel between source and drain. N-channel enhancement-mode MOSFETs are the dominant switch topology in high-current DC-DC converters, motor drives, and synchronous-rectifier stages because their lower RDS(on) per unit silicon area delivers higher efficiency than P-channel counterparts. The IAUT family targets 48 V automotive subsystems (e.g., mild-hybrid ECUs, electric power steering, braking systems, brushless DC pumps and fans) where the 80 V drain rating provides ample headroom for transients on a nominal 48 V bus.
Key features include 1.4 mΩ typical RDS(on) at VGS=10 V, 300 A continuous DC ID at TC=25 °C, 300 W maximum power dissipation at TC=25 °C, AEC-Q101 automotive qualification, MSL1 floor-life (unlimited at ≤30 °C/85 % RH), RoHS-compliant lead-free package, 100 % avalanche-tested die, and an ultra-low figure of merit (FOM = RDS(on) × Qg) for fast-switching applications. The tab is the drain, which must be soldered to a sufficiently large copper pour to act as both thermal via and electrical node.
The die is built on Infineon's OptiMOS 5 trench technology, which lowers both on-resistance per cell and gate charge, thereby reducing conduction and switching losses simultaneously compared to earlier planar or stripe-cell generations. The PG-HSOF-8-1 package exposes the die directly to the PCB through a large source-clip lead frame, giving a junction-to-case thermal resistance typically below 0.5 °C/W and enabling the 300 W dissipation rating when the PCB thermal path is properly designed.
Typical applications include 48 V mild-hybrid automotive DC-DC converters, high-current brushless DC (BLDC) motor drives for electric power steering and water/oil pumps, automotive e-fuse and battery disconnect switches, synchronous rectification in telecom and server buck converters, and high-current solenoid/relay driver stages. The 80 V rating and 300 A pulse capability also suit industrial inverter sections operating from 24-48 V battery rails.
When designing with this part, keep the switching-node loop area minimal to control parasitic inductance and voltage overshoot, use a gate driver capable of sourcing/sinking 1-2 A peak to charge Qg quickly, and lay out at least 100-200 cm² of 2 oz copper on the drain tab to stay below the SOA envelope at high DC currents.

Типичное применение
IAUT300N08S5N014ATMA1 подходит для 6 применениеs: 48V Mild-Hybrid DC-DC Converter, Automotive BLDC Motor Drive (EPS / Pumps / Fans), Automotive e-Fuse / Battery Disconnect Switch, 48V Synchronous Rectification (Telecom / Server Buck), Industrial High-Current Solenoid / Relay Driver, 48V Inverter Power Stage (Auxiliary Drives).
48V Mild-Hybrid DC-DC Converter
The IAUT300N08S5N014ATMA1 fits 48 V mild-hybrid automotive DC-DC converters as a high-side or low-side synchronous switch. Its 80 V VDS handles 48 V nominal plus inductive overshoot to ~60 V, while 300 A continuous ID covers 100-200 A converter designs with thermal margin. The 1.4 mΩ RDS(on) at VGS=10 V keeps full-load conduction loss under 30 W at 150 A, well below the 300 W PD rating, and OptiMOS 5's low Qg enables >100 kHz switching for smaller magnetics.

Automotive BLDC Motor Drive (EPS / Pumps / Fans)
The IAUT300N08S5N014ATMA1 serves as the half-bridge switch in automotive 48 V BLDC motor drives for electric power steering, coolant pumps, oil pumps, and HVAC fans. Its 300 A pulsed ID handles the inrush of mechanical-load transients, and the AEC-Q101 qualification plus 175 °C junction rating satisfy under-the-hood thermal requirements. The PG-HSOF-8-1 tab provides <0.5 °C/W junction-to-case thermal resistance, allowing sustained 100-150 A RMS phase currents when the PCB thermal path is engineered.
Рекомендуется
Automotive e-Fuse / Battery Disconnect Switch
The IAUT300N08S5N014ATMA1 is well-suited for 48 V e-fuse and battery disconnect switch positions where it must carry continuous DC bus current and interrupt fault currents within microseconds. Its 1.4 mΩ RDS(on) at full VGS keeps full-load voltage drop below 150 mV at 100 A, minimizing parasitic loss. The 100 % avalanche-tested die and ±20 V VGS rating provide robustness against inductive kick during fault interruption, while the AEC-Q101 screening satisfies ISO 26262 functional-safety design flows.
Рекомендуется
48V Synchronous Rectification (Telecom / Server Buck)
The IAUT300N08S5N014ATMA1 works as a synchronous-rectifier low-side switch in 48 V-input telecom and server buck converters. Its 1.4 mΩ RDS(on) at VGS=10 V competes effectively with planar MOSFETs at half the figure of merit, while 300 A DC handles >3 kW converter power levels with paralleled phase count kept low. The 80 V VDS leaves comfortable margin for 48 V nominal plus 5-10 V transient overshoot, and the OptiMOS 5 process minimizes reverse-recovery charge for zero-voltage-switching topologies.
Рекомендуется
Industrial High-Current Solenoid / Relay Driver
The IAUT300N08S5N014ATMA1 can drive large industrial solenoids and contactors from 24-48 V battery rails where peak currents exceed 100 A and switch events occur in <10 ms. Its 100 % avalanche rating absorbs the inductive kick at turn-off, eliminating external TVS clamp circuits and saving BOM cost. The 300 A continuous ID comfortably handles the steady-state holding current of hydraulic valves, while 175 °C junction allows sealed-enclosure mounting near the actuator.
Рекомендуется
48V Inverter Power Stage (Auxiliary Drives)
The IAUT300N08S5N014ATMA1 forms the inverter power stage for 48 V three-phase auxiliary drives used in industrial automation and mild-hybrid accessory drives. Its 300 A ID per switch allows paralleled design without device count explosion, while OptiMOS 5's low Qg reduces drive loss at 20-50 kHz PWM. The HSOF-8-1 tab doubles as the phase node thermal anchor, simplifying PCB layout when paired with the recommended Infineon TLE9180D32QKXUMA1 gate driver.

Заметки по проектированию
Estimated thermal analysis: at PD=10 W continuous, the PG-HSOF-8-1 with θJA of approximately 50 °C/W on a 1 oz FR4 100 cm² copper pour yields a junction-to-ambient rise of ~10 °C above ambient. For sustained 300 A operation, the drain tab must be soldered to at least 200 cm² of 2 oz copper on both top and bottom layers with thermal vias (24 vias minimum, 0.3 mm drill) to keep Tj below 150 °C at TA=85 °C ambient. Derate ID linearly per the SOA curve.
Minimize the high-side / low-side switching-node copper loop to control parasitic inductance and VDS overshoot. Place the gate driver within 10 mm of the GATE pin and use a 10 Ω gate resistor to damp ringing. Keep the source return path directly under the source pins and never share it with the gate-drive return - use a Kelvin source connection when possible. Decouple VCC of the gate driver with a 100 nF X7R placed within 5 mm of the IC.
Do not exceed VGS=±20 V (transient). Use a gate-source resistor (10 kΩ typical) to keep the device off during controller power-up and prevent inadvertent turn-on from Miller coupling. Avoid operating continuously above 175 °C Tj. For pulse currents above the DC SOA, limit pulse duration and duty cycle per the single-pulse thermal impedance curve (ZthJC) - at 1 ms pulse the part can briefly carry 5-10x the DC rating.
Use NSMD (non-solder mask defined) land pads to increase solder joint reliability on the source pins. For the drain tab, use a single large NSMD pad (~7 mm × 7 mm) with thermal via array in the centre. The MSL1 rating allows unlimited floor life at ≤30 °C/85 % RH, but still respect standard ESD handling precautions during assembly (HBM Class 1C, CDM Class C3 typical for OptiMOS 5).
