Product details

Overview

IAUC45N04S6L063H from Infineon Technologies is an AEC-Q101-qualified N-channel logic-level power MOSFET in PG-TDSON-8-57 package, rated for 40 V V_DS, 6.3 mΩ R_DS(on) at V_GS = 10 V, and 45 A continuous drain current at T_C = 85 °C. It serves as a half-bridge high-side or low-side switch in automotive motor control and DC-DC converters.

For engineers reviewing the IAUC45N04S6L063H datasheet, IAUC45N04S6L063H pinout, IAUC45N04S6L063H application, or IAUC45N04S6L063H equivalent, key selection criteria include its 175 °C operating temperature, 100% avalanche tested ruggedness, 3.7 K/W R_thJC, and logic-level gate drive compatibility with 4.5 V microcontrollers.

Technical Context

This OptiMOS™-6 device uses trench-based silicon technology optimized for low conduction and switching losses in automotive 12 V systems. Its gate threshold voltage (1.2–2.0 V) enables reliable turn-on with standard logic-level drivers, while its 7.4 mΩ R_DS(on) at V_GS = 4.5 V supports efficient operation in battery-powered ECUs.

The MOSFET integrates a robust body diode with 20 ns t_rr and 8 nC Q_rr, enabling fast freewheeling in synchronous rectification. Its MSL1 rating and 260 °C peak reflow tolerance ensure compatibility with lead-free PCB assembly processes.

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 @ V_GS=10 V	6.3 mΩ - Enables ≤1.4 W conduction loss at 45 A, reducing heatsink requirements.
I_D continuous @ T_C=85 °C	45 A - Sustains full-load current in compact motor driver modules without derating.
E_AS single pulse	38 mJ - Withstands inductive energy spikes in solenoid and BLDC phase-leg switching.
R_thJC	3.7 K/W - Supports direct thermal coupling to copper pads or heatsinks for high-power density layouts.
Q_g total	10–13 nC - Low gate charge enables fast switching with <10 ns rise/fall times using 3.5 Ω gate resistor.
t_rr	20 ns - Minimizes reverse recovery losses during hard commutation in half-bridge configurations.
V_GS(th)	1.2–2.0 V - Ensures stable turn-on with 3.3 V/5 V MCU GPIOs without level-shifting circuitry.

Pinout & Package

PG-TDSON-8-57 is a thermally enhanced 8-pin surface-mount package with exposed drain pad (pins 1–3, 5–8 = source; pin 4 = gate; pin 6 = drain tab). The footprint complies with JEDEC MO-263AB and enables low-inductance, high-current routing.

Pin/Terminal	Circuit Role	Design Meaning
1,2,3,5,7,8	Source	Common source connection for dual-channel half-bridge layout; low-inductance parallel routing reduces shoot-through risk.
4	Gate	Logic-level input requiring <13 nC total charge; isolated from drain by 16 V max V_GS rating.
6	Drain (exposed pad)	Main power output node; soldered to large copper pour for thermal dissipation and EMI suppression.

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
STL220N4LF8AG	40 V, 2.2 mΩ R_DS(on) @ 10 V, but 8 mm × 8 mm PowerFLAT™ 8x8 package vs. PG-TDSON-8-57's 5.15 mm × 6.25 mm footprint.	Higher current capability (220 A pulsed), but larger board area and higher gate charge (29 nC).	Prefer for ultra-low R_DS(on) needs where space and gate drive strength permit.
ON Semiconductor NTMFS4C09NT1G	40 V, 7.0 mΩ R_DS(on) @ 10 V, same PG-TDSON-8 package, but only AEC-Q101 qualified at T_j ≤ 150 °C (not 175 °C).	Limited high-temperature operation in under-hood locations exceeding 150 °C ambient.	Select when cost sensitivity outweighs extended thermal margin requirement.

Compared with STL220N4LF8AG and NTMFS4C09NT1G, IAUC45N04S6L063H delivers optimal balance of compact size, 175 °C operation, and logic-level drive-critical for space-constrained, high-reliability automotive modules where thermal headroom and MCU compatibility are prioritized over absolute lowest R_DS(on).

FAQ

What is the maximum allowable gate-source voltage for IAUC45N04S6L063H?

The absolute maximum V_GS is ±16 V, as specified in the Absolute Maximum Ratings table. Exceeding this value risks permanent gate oxide damage. For reliable operation, gate drive circuits must clamp voltage within this limit using Zener diodes or active clamping, especially during fast switching transients or ESD events.

Can IAUC45N04S6L063H be used in parallel configurations?

Yes-its positive temperature coefficient of R_DS(on) (increasing resistance with junction temperature) enables inherent current sharing. Successful parallel operation requires matched gate drive impedance, symmetrical PCB layout, and thermal coupling via shared copper pour to minimize thermal imbalance between devices.

Is the body diode suitable for continuous freewheeling in synchronous rectification?

Yes-the integrated body diode is rated for 45 A continuous forward current at T_C = 25 °C and exhibits 0.85–1.1 V V_SD at 22 A and 25 °C. Its 20 ns t_rr and low Q_rr (8 nC) make it appropriate for high-frequency synchronous rectification in buck converters up to 1 MHz.

Does IAUC45N04S6L063H require a gate resistor for safe operation?

Yes-a gate resistor (typically 3.5 Ω for 10–13 nC Q_g) is required to control dV/dt and prevent parasitic oscillation or shoot-through in bridge configurations. The resistor also limits peak gate current during switching and dampens ringing caused by PCB trace inductance and gate capacitance interaction.
