Typical Applications
IAUZ40N10S5N130ATMA1 is suitable for 7 applications: 48V Mild-Hybrid Automotive DC-DC Converter, Automotive LED Lighting Drivers, Synchronous Rectification in SMPS, BLDC Motor Drive Half-Bridge, Solar Microinverter / Power Optimizer, Battery Protection & Hot-Swap, USB-PD High-Current Sink.
48V Mild-Hybrid Automotive DC-DC Converter
The IAUZ40N10S5N130ATMA1 is well suited for 48 V mild-hybrid DC-DC converter primary and secondary-side switches, where its 100 V V<sub>DS</sub> rating provides >2x transient margin above the 48 V nominal bus and its 13 mΩ max R<sub>DS(on)</sub> minimizes conduction loss in high-current 1-2 kW power stages. Placed in a half-bridge or synchronous buck topology with 100-200 kHz switching frequency, the OptiMOS 5 die's low Q<sub>g</sub> reduces driver losses and enables smaller magnetics. AEC-Q101 qualification supports ASIL-B system integration for safety-relevant powertrain ECUs, and the 3.3 × 3.3 mm PG-TSDSON-8-33 package saves board area versus D2PAK alternatives.
Recommended
Automotive LED Lighting Drivers
In automotive LED headlamp and daytime-running-light driver stages, the IAUZ40N10S5N130ATMA1 serves as the high-side or low-side switch in buck/boost LED current regulators. Its 40 A continuous current comfortably drives multi-LED strings up to 5-10 A per channel, and its 10 mΩ typical R<sub>DS(on)</sub> keeps conduction loss under 1 W at full load, eliminating the need for an external heatsink on the lighting PCB. AEC-Q101 qualification meets automotive headlamp reliability targets, and the small PG-TSDSON-8-33 footprint enables compact driver layouts inside headlamp housings where thermal headroom is constrained.
Recommended
Synchronous Rectification in SMPS
The IAUZ40N10S5N130ATMA1 functions as the synchronous rectifier MOSFET in 48 V-input telecom, server, and industrial SMPS, replacing Schottky diodes to gain 1-3% system efficiency. At 100 V V<sub>DS</sub> it handles 48 V nominal with adequate transient margin for telecom battery plants, and its 13 mΩ on-resistance minimizes rectifier conduction loss at 20-30 A output currents. The OptiMOS 5 technology provides an excellent R<sub>DS(on)</sub> × Q<sub>g</sub> figure of merit, allowing high-frequency (200-500 kHz) operation without sacrificing efficiency, which directly reduces magnetic component size.
Recommended
BLDC Motor Drive Half-Bridge
In 48 V brushless-DC (BLDC) motor drives for electric power-steering, water pumps, and HVAC blowers, the IAUZ40N10S5N130ATMA1 is deployed as the low-side switch in a three-phase inverter. Its 40 A continuous and 160 A pulsed ratings handle motor inrush and reverse-recovery transients, while the 10 mΩ typical R<sub>DS(on)</sub> reduces I²R heating that would otherwise demand active cooling. The compact PG-TSDSON-8-33 package lets the inverter fit inside the motor housing or ECU, and AEC-Q101 qualification is essential for automotive motor-control safety standards.
Recommended
Solar Microinverter / Power Optimizer
In residential solar microinverters and DC power optimizers, the IAUZ40N10S5N130ATMA1 serves as the high-frequency primary switch in isolated or non-isolated DC-DC stages. Its 100 V V<sub>DS</sub> rating suits 60 V<sub>oc</sub> PV panel maximum power points with >1.5x safety margin against cold-panel open-circuit transients, and its low Q<sub>g</sub> supports 100-300 kHz operation that reduces transformer and inductor size. The OptiMOS 5 efficiency gain over older MOSFET generations directly improves CEC-weighted inverter efficiency by 0.3-0.5%, which materially affects solar energy yield over the system's 25-year lifetime.
Recommended
Battery Protection & Hot-Swap
In 48 V battery protection circuits, hot-swap controllers, and e-fuse designs, the IAUZ40N10S5N130ATMA1 acts as the main disconnect / current-limit switch. Its 13 mΩ R<sub>DS(on)</sub> keeps the path loss under 50 mV at 40 A load, preserving system efficiency during normal operation, while its 160 A pulsed rating handles inrush transients during hot-plug events. The PG-TSDSON-8-33 package is footprint-compatible with standard hot-swap reference designs, simplifying layout migration from older D2PAK or SO-8 parts.
Recommended
USB-PD High-Current Sink
In 100 W-class USB Power Delivery sink designs, the IAUZ40N10S5N130ATMA1 is used as the protection / hot-swap switch on the 20 V input rail from a Type-C connector. Its 100 V rating easily handles 28 V PD EPR (Extended Power Range) transients with significant margin, and its 13 mΩ on-resistance introduces less than 50 mV drop at 5 A continuous load. The PG-TSDSON-8-33 package footprint is small enough to fit inside a laptop docking station's tight board area while dissipating 5-8 W without forced cooling.

Design Notes
Estimated: at 68 W maximum dissipation and a typical PG-TSDSON-8-33 RθJA near 50 °C/W on a 4-layer 2-oz FR-4 board, junction temperature rise is roughly 50 °C above ambient at full DC load. The exposed drain pad must be soldered to at least 25 mm² of continuous top-side copper to maintain thermal headroom, with thermal vias to inner copper planes for additional spreading. For continuous operation at currents above 25 A, design the copper area around the package to keep junction-to-ambient below 100 °C.
Keep the gate-drive loop area under 1 cm² by routing the gate trace directly over the drain copper, and place the gate-driver IC adjacent to the gate pin to minimize parasitic inductance. Use a 10 Ω gate-source resistor and a small gate-driver pull-up to prevent false turn-on from drain-voltage transients. Kelvin source connection is provided by dedicated source pins; do not use the exposed drain pad as the only ground return path.
Do not exceed VGS = ±20 V absolute maximum; OptiMOS 5 gate oxide is sensitive to overvoltage and ESD. Add a 10 kΩ gate pull-down to guarantee the FET stays off during controller power-up. The R<sub>DS(on)</sub> specification is given at VGS = 10 V; driving at 4.5 V (logic-level) will increase on-resistance by 50-100%, and at 6 V by 20-30%. Use a true 10 V gate drive for full rated performance.
Recommended land pattern follows JEDEC MO-240 with the central thermal pad at 2.0 × 2.0 mm minimum. Use NSMD (non-solder-mask-defined) pads on the source leads to control solder joint thickness and improve thermal-cycle reliability. A 4-layer stack-up with 2 oz top copper for the drain thermal pad and 1 oz inner planes is recommended for automotive applications targeting 1000+ thermal cycles per AEC-Q101.
