IAUZ30N10S5L240ATMA1 Обзор
An N-channel power MOSFET is a voltage-controlled majority-carrier device that uses a gate-source electric field to modulate conduction between drain and source terminals. Within the semiconductor hierarchy it belongs to discrete transistors → MOSFETs → power MOSFETs → low-voltage trench MOSFETs. OptiMOS 5 is Infineon's fifth-generation trench technology, which optimizes figure-of-merit (FOM = R<sub>DS(on)</sub> × Q<sub>g</sub>) for high-frequency switching and reduced conduction loss, replacing earlier planar and earlier-trench generations.
Key specifications include 100 V drain-source breakdown (V<sub>(BR)DSS</sub>), 24 mΩ R<sub>DS(on)</sub> at V<sub>GS</sub>=10 V (per the manufacturer datasheet), gate charge of 14 nC, and input capacitance of 832 pF at V<sub>DS</sub>=50 V. The PG-TSDSON-8-32 package provides a Kelvin-source connection and an exposed metal pad that simultaneously serves as the drain terminal and the primary thermal path to the PCB, enabling high current density in compact layouts. The part dissipates up to 45.5 W (Tc) under manufacturer-defined thermal conditions.
Typical applications include automotive 12 V/24 V load switching, high-side and low-side switches in DC-DC buck/boost converters, motor drive half-bridges for pumps and fans, and reverse-battery protection circuits. The 100 V rating also provides ample transient margin for 24 V systems that experience load-dump events. Compared with the previous OptiMOS 3 generation, the IAUZ30N10S5L240 reduces R<sub>DS(on)</sub> by approximately 30% at the same die size, reducing conduction loss and improving thermal performance.
When designing with this part, place gate-drive resistors close to the gate pin to limit ringing, and provide a 10 kΩ gate-source pull-down to prevent accidental turn-on during supply transients. The Kelvin-source pin must be bonded directly to the IC's source pad and to the gate-driver ground return to avoid source-induced gate-drive loss. This page synthesizes distributor pricing, drop-in alternatives, and PCB-level design notes beyond what appears in the manufacturer datasheet.

Типичное применение
IAUZ30N10S5L240ATMA1 подходит для 6 применениеs: Automotive 12V/24V Load Switching, DC-DC Buck/Boost Converter Power Stage, Motor Drive Half-Bridge (Pumps, Fans, BLDC), Reverse-Battery Protection (RBP) and OR-ing, Hot-Swap / In-Rush Current Limiting, LED Driver Power Switch (Automotive Lighting).
Automotive 12V/24V Load Switching
The IAUZ30N10S5L240ATMA1's 100 V V<sub>DS</sub> rating and AEC-Q101 qualification make it a strong fit for high-side and low-side load switching in 12 V and 24 V automotive body-electronics modules. Its 24 mΩ R<sub>DS(on)</sub> at V<sub>GS</sub>=10 V keeps conduction loss low enough that a 20 A continuous ECU load dissipates only ~9.6 W, manageable by the PG-TSDSON-8-32 exposed-pad footprint on 1 oz copper. The 100 V rating also provides ≥30 V margin above 24 V load-dump events per ISO 7637-2.
Рекомендуется
DC-DC Buck/Boost Converter Power Stage
The IAUZ30N10S5L240ATMA1 is well suited to the synchronous-rectifier and control-FET positions in 12 V-to-3.3 V/5 V buck converters used in automotive ECU power trees. Its 14 nC Q<sub>g</sub> supports switching frequencies up to ~500 kHz with acceptable driver loss, and its 24 mΩ R<sub>DS(on)</sub> balances conduction and switching loss at full load. The exposed-drain pad also acts as a heatsink, eliminating an external thermal solution.
Рекомендуется
Motor Drive Half-Bridge (Pumps, Fans, BLDC)
For automotive water pumps, oil pumps, cooling fans, and small BLDC actuators, the IAUZ30N10S5L240ATMA1 forms the low-side or high-side switch in a three-phase or half-bridge inverter. Its 30 A continuous rating covers single-digit-ampere motor windings with substantial peak surge headroom for inrush currents. The AEC-Q101 screening ensures reliability under the repetitive thermal cycling of motor-driven automotive environments from -40°C to +150°C ambient.
Рекомендуется
Reverse-Battery Protection (RBP) and OR-ing
In automotive ECUs that require reverse-battery and load-dump protection, the IAUZ30N10S5L240ATMA1 can be placed in series with the supply rail as a self-controlled reverse-blocking element. The 100 V V<sub>DS</sub> rating and the body's intrinsic diode handle the negative transient during a reverse-battery event. At 24 mΩ, the steady-state voltage drop is minimal (≈0.5 V at 20 A) compared to a Schottky-diode solution that would dissipate excessive power.
Рекомендуется
Hot-Swap / In-Rush Current Limiting
The IAUZ30N10S5L240ATMA1 can act as the pass element in a hot-swap controller for plug-in automotive or industrial modules. Driving the gate with a controlled current source or an RC ramp allows soft-start of large bulk capacitors, while the 30 A I<sub>D</sub> rating supports continuous operation at moderate load. The 100 V rating survives transients when the upstream rail is a 24 V industrial bus or 48 V mild-hybrid system stepped down for an auxiliary module.
Рекомендуется
LED Driver Power Switch (Automotive Lighting)
For matrix-LED headlamps, daytime running lights, and tail-lamp current drivers, the IAUZ30N10S5L240ATMA1 can serve as the high-side PWM switch that modulates string current. The fast switching speed supported by 14 nC Q<sub>g</sub> enables PWM dimming above the audible band (>200 Hz) without efficiency penalty, and AEC-Q101 qualification ensures photometric stability over the vehicle's lifetime. The 30 A rating covers multi-string LED modules up to ~100 W total.

Заметки по проектированию
Estimated: at continuous 30 A and R<sub>DS(on)</sub>=24 mΩ, the IAUZ30N10S5L240ATMA1 dissipates P = I² × R = 30² × 0.024 = 21.6 W. The PG-TSDSON-8-32 package has a typical θ<sub>JA</sub> in the 35–50 °C/W range when soldered to 1 oz copper of about 1 square inch; this yields a junction-temperature rise of roughly 760–1080 °C above ambient — clearly unacceptable. The exposed drain pad MUST be soldered to a copper pour of at least 1–2 square inches on inner PCB layers with thermal vias to achieve the rated 45.5 W (Tc) dissipation. Designers should always perform thermal simulation with the actual PCB stack-up before committing to layout.
Use a Kelvin-source connection (pin 2) tied directly to the gate-driver ground return, separate from the high-current source pad bond. This eliminates the source-inductance negative-feedback effect that slows switching edges and can cause false turn-on during high di/dt events. Place a 10 kΩ gate-to-source pull-down resistor on the PCB so the device stays off if the gate-driver output floats during power-up. Use wide source-trace copper and stitch the ground plane beneath the drain pad with multiple thermal vias (10+ vias, 0.3 mm drill) for low thermal resistance.
Common pitfalls with the IAUZ30N10S5L240ATMA1: (1) driving the gate from a non-automotive-grade gate driver with insufficient V<sub>GS</sub> headroom — Infineon specifies V<sub>GS</sub>=±20 V absolute maximum; (2) omitting TVS protection across drain-source for load-dump events even though 100 V V<sub>DS</sub> gives margin — inductive transients can exceed the rating during relay/coil turn-off; (3) assuming 5 V V<sub>GS</sub> drive is sufficient — OptiMOS 5 is optimized for 10 V gate drive, and 5 V drive can nearly double R<sub>DS(on)</sub>; (4) using the same gate-drive resistor value as a smaller FET — at 14 nC Q<sub>g</sub>, the gate-drive loop must be tuned for 30 A switching transients.
