Product details

Overview

IAUC120N04S6N010ATMA1 from Infineon Technologies is an AEC-Q101-qualified N-channel enhancement-mode power MOSFET in PG-TDSON-8 package, rated for 40 V V_DS, 1.0 mΩ max R_DS(on) at V_GS = 10 V, and 120 A continuous drain current at T_C = 25 °C. It operates up to 175 °C junction temperature and is 100% avalanche tested-designed for high-efficiency automotive power stages including BLDC motor control and DC-DC converters.

For engineers reviewing the IAUC120N04S6N010ATMA1 datasheet, IAUC120N04S6N010ATMA1 pinout, IAUC120N04S6N010ATMA1 application, or IAUC120N04S6N010ATMA1 equivalent, key selection criteria include its 1.0 mΩ R_DS(on), 480 A pulsed drain capability, 400 mJ single-pulse avalanche energy, MSL1 reflow rating, and integrated source-drain diode with 57 ns t_rr.

Technical Context

This OptiMOS™-6 device uses trench-based silicon technology optimized for low R_DS(on) × Q_g figure-of-merit in automotive 12 V systems. Its gate threshold voltage (2.2–3.0 V) enables robust TTL/CMOS-level drive compatibility while maintaining noise immunity.

The MOSFET integrates a fast-recovery body diode (t_rr = 57 ns, Q_rr = 64 nC) and exhibits low output capacitance (C_oss = 1602–2082 pF), supporting high-frequency switching in synchronous rectification and half-bridge topologies.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	40 V - Maximum blocking voltage for 12 V automotive battery rail applications with transient margin.
R_DS(on) max	1.0 mΩ @ V_GS = 10 V - Enables <1.2 W conduction loss at 120 A, critical for thermal management in compact ECUs.
I_D cont	120 A @ T_C = 25 °C - Package-limited current handling suitable for high-power motor phases and starter solenoid drivers.
E_AS	400 mJ - Confirmed single-pulse avalanche ruggedness supports inductive load switching without external snubbers.
t_rr	57 ns - Fast body diode recovery reduces switching losses and EMI in synchronous buck and H-bridge configurations.
R_thJC	1.0 K/W - Enables direct heatsink mounting for efficient thermal transfer in space-constrained automotive modules.

Pinout & Package

IAUC120N04S6N010ATMA1 is housed in PG-TDSON-8 (exposed drain pad), a thermally enhanced 5 mm × 6 mm surface-mount package with 1.27 mm pitch. The exposed drain pad provides low-inductance, high-current path and primary thermal interface to PCB copper.

Pin/Terminal	Circuit Role	Design Meaning
1–3, 5–7	Source	Parallel-source configuration lowers on-resistance and improves current sharing across multiple pins.
4	Gate	Single low-capacitance gate input (Q_g = 81–108 nC) compatible with standard gate drivers.
8	Drain (Exposed Pad)	Thermally and electrically connected to internal die drain; must be soldered to large PCB copper area for thermal and electrical performance.

Key Features

Feature	Design Value

Equivalent & Alternatives

The following parts are listed as comparable options for similar N-channel automotive power MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
IAUZ40N04S5L022ATMA1	Higher R_DS(on) (2.2 mΩ), lower I_D (40 A), same 40 V rating and PG-TDSON-8 package.	Better suited for lower-current auxiliary loads (e.g., seat heaters, pumps) where thermal budget allows higher on-resistance.	Select when cost sensitivity outweighs conduction loss requirements and peak current stays below 45 A.
IPB180N04S4H02ATMA1	Same 40 V rating but higher R_DS(on) (2.0 mΩ), 180 A rating, larger TO-263-7 package with different thermal interface.	Requires larger PCB footprint and different heatsinking; used in high-current engine control modules where package size is less constrained.	Choose only if system layout permits TO-263-7 and thermal design targets >150 A continuous operation.

Compared with IAUZ40N04S5L022ATMA1 and IPB180N04S4H02ATMA1, IAUC120N04S6N010ATMA1 delivers optimal balance of ultra-low R_DS(on), compact PG-TDSON-8 footprint, and automotive-grade ruggedness for mid-to-high power 12 V applications where board space and thermal resistance are critical.

FAQ

What is the maximum allowable gate-source voltage for IAUC120N04S6N010ATMA1?

The absolute maximum gate-source voltage is ±20 V. Operation beyond this range risks permanent gate oxide damage. Recommended drive is 10 V for full enhancement, with minimum 4.2 V gate plateau voltage ensuring reliable turn-on under varying conditions.

Does IAUC120N04S6N010ATMA1 require a gate resistor for safe switching?

Yes-a gate resistor is required to control dV/dt and prevent oscillation. Typical values range from 2.2 Ω to 10 Ω depending on driver strength and layout parasitics. The device's Q_g of 81–108 nC and Q_gd of 16–24 nC inform optimal gate drive design for 200–500 kHz operation.

Can IAUC120N04S6N010ATMA1 be used in parallel configurations?

Yes-its positive temperature coefficient of R_DS(on) enables stable current sharing. Layout symmetry, matched gate drive paths, and identical thermal mounting are essential. Derating by 15% per device is recommended for sustained parallel operation above 200 A total.

Is the body diode suitable for synchronous rectification in DC-DC converters?

Yes-the body diode has characterized t_rr = 57 ns and Q_rr = 64 nC at T_j = 25 °C, making it viable for synchronous rectification up to ~300 kHz. Performance degrades above 125 °C, so thermal design must maintain junction temperature below 150 °C for consistent recovery behavior.
