Product details

Overview

IAUA180N10S5N029AUMA1 from Infineon is an N-channel enhancement-mode automotive power MOSFET in PG-HSOF-5-4 package, rated for 100 V V_DS, 2.9 mΩ R_DS(on) at V_GS = 10 V and I_D = 90 A, with 175 °C maximum junction temperature and AEC-Q101 qualification. It serves as a high-current main switch in 12 V/24 V automotive power distribution systems including battery disconnect and motor control.

For engineers reviewing the IAUA180N10S5N029AUMA1 datasheet, IAUA180N10S5N029AUMA1 pinout, IAUA180N10S5N029AUMA1 application, or IAUA180N10S5N029AUMA1 equivalent, key selection criteria include R_DS(on) stability over temperature, single-pulse avalanche energy (E_AS = 561 mJ), gate charge (Q_g = 81–105 nC), and MSL3 reflow compatibility up to 260 °C.

Technical Context

This OptiMOS™-5 device uses trench-gate superjunction technology optimized for low conduction loss and fast switching in automotive DC-DC converters and high-side load switches. Its 2.3–2.9 mΩ R_DS(on) range (V_GS = 10 V, I_D = 90 A) and 1.4 Ω typical gate resistance support robust gate drive design under high dV/dt conditions.

The MOSFET features 100% unclamped inductive switching (UIS) tested to 561 mJ at T_C = 25 °C, and reverse diode parameters include V_SD = 0.9–1.2 V at I_F = 90 A and t_rr = 62 ns - enabling efficient freewheeling in H-bridge motor drivers without external Schottky supplementation.

Key Specifications

FAQ

What is the maximum allowable gate-source voltage for IAUA180N10S5N029AUMA1?

The absolute maximum V_GS is ±20 V per the datasheet. Operation above +15 V or below –10 V risks permanent gate oxide damage. For reliable enhancement, V_GS should be maintained between 4.7 V (plateau voltage) and 10 V - higher voltages reduce R_DS(on) but increase Q_g demand and ESD sensitivity.

Does IAUA180N10S5N029AUMA1 require a gate resistor in automotive applications?

Yes - a gate resistor (typically 3.5–10 Ω) is required to dampen ringing, control dV/dt, and limit peak gate current during switching. Infineon's recommended test condition uses R_G = 3.5 Ω; values below 2 Ω increase risk of oscillation and shoot-through in bridge configurations.

How does the dual-source pin configuration improve performance?

Pins 2 and 4 are both internally connected to source - this reduces effective source inductance by ~40% versus single-source packages, minimizing voltage overshoot during turn-off and improving current sharing in paralleled devices. It also enables Kelvin source sensing for accurate current measurement without disturbing the main power loop.

Is IAUA180N10S5N029AUMA1 suitable for 48 V mild hybrid systems?

Yes - its 100 V V_DS rating provides sufficient margin for 48 V nominal systems experiencing ISO 16750-2 load dump transients up to 65 V. Combined with 175 °C T_j max and 561 mJ E_AS, it supports reliable operation in bidirectional DC-DC converters and regenerative braking interfaces.
