Product details

Overview

IAUC45N04S6N070HATMA1 from Infineon Technologies is an AEC-Q101 qualified automotive-grade N-channel enhancement-mode power MOSFET in PG-TDSON-8-57 package, rated for 40 V V_DS, 7.0 mΩ R_DS(on) at V_GS = 10 V, and 45 A continuous drain current at T_C = 85 °C. It operates up to 175 °C junction temperature and is 100% avalanche tested for robustness in half-bridge motor control and DC-DC converter stages.

For engineers reviewing the IAUC45N04S6N070HATMA1 datasheet, IAUC45N04S6N070HATMA1 pinout, IAUC45N04S6N070HATMA1 application, or IAUC45N04S6N070HATMA1 equivalent, key selection criteria include its 3.7 K/W R_thJC, 9.0 nC total gate charge, 539 pF input capacitance, and MSL1 reflow compatibility - critical for high-reliability automotive power stage design.

Technical Context

This OptiMOS™-6 device implements a normal-level gate drive architecture optimized for half-bridge configurations with integrated body diode recovery (t_rr = 16 ns, Q_rr = 6 nC). Its R_DS(on) remains stable across -55 °C to 175 °C (7.0 mΩ max at 25 °C, 14.5 mΩ at 175 °C), supporting wide-temperature operation without derating penalties.

The MOSFET features low Crss (21 pF max) and fast switching (t_d(on) = 3 ns, t_f = 2 ns) under 3.5 Ω gate resistance, enabling high-frequency PWM in 48 V mild-hybrid systems while maintaining EMI control via controlled dV/dt.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	40 V - Maximum blocking voltage for 48 V automotive bus applications
R_DS(on) max	7.0 mΩ at V_GS = 10 V, I_D = 22 A - Enables <1.5 W conduction loss at 45 A in half-bridge high-side
I_D continuous	45 A at T_C = 85 °C - Supports sustained motor phase current in EPS and HVAC blowers
E_AS	38 mJ single-pulse - Withstands inductive kickback without failure in brushed DC motor drives
Q_g	9–12 nC - Low gate drive power requirement for 100 kHz+ synchronous rectification
R_thJC	3.7 K/W - Enables direct heatsink mounting for thermal management in compact ECUs
t_rr	16 ns - Minimizes body diode reverse recovery loss in hard-switched buck converters

Pinout & Package

PG-TDSON-8-57 is a thermally enhanced 8-pin exposed-pad surface-mount package with dual drain-source paralleling capability. The exposed thermal pad (pin 8) must be soldered to PCB copper for optimal R_thJC performance.

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 3, 4, 5, 6	Drain (D)	Internally paralleled drain terminals - reduce current density and parasitic inductance in high-current paths
7	Source (S)	Main source connection - referenced ground node for gate driver feedback and current sensing
8	Thermal Pad / Drain	Exposed copper pad tied to drain potential - primary thermal path to PCB heatsink
G	Gate (G)	Single gate input (pin not numbered; located between pins 6 and 7 per outline) - requires <10 Ω series resistance for EMI control

Key Features

Feature	Design Value
AEC-Q101 qualification	Validated for automotive powertrain and chassis applications per stress test requirements
100% unclamped inductive switching (UIS) tested	Guarantees single-pulse avalanche energy handling up to 38 mJ at 25 °C
MSL1 rating (260 °C peak reflow)	Enables standard lead-free SMT assembly without moisture sensitivity concerns
Low Crss (21 pF max)	Reduces Miller-induced shoot-through risk in high-dV/dt half-bridge environments
175 °C operating temperature	Supports placement near heat sources (e.g., inverters, DC-DC stages) without derating

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
IAUZ40N04S5N012HATMA1	Lower R_DS(on) (1.2 mΩ), higher Q_g (22 nC), same 40 V rating	Better conduction efficiency but higher switching loss above 50 kHz	Select when thermal budget allows larger heatsink and switching frequency ≤30 kHz
IPB180N04S4-02	Higher R_DS(on) (2.0 mΩ), TO-263 package, no MSL1 rating	Limited to manual or selective reflow; unsuitable for automated SMT lines	Select only for prototyping or low-volume repair where reflow compatibility is not required

Compared with IAUZ40N04S5N012HATMA1 and IPB180N04S4-02, IAUC45N04S6N070HATMA1 delivers optimal balance of low R_DS(on), moderate Q_g, and full automotive SMT readiness - making it preferred for volume production of 48 V power modules requiring MSL1 and AEC-Q101 compliance.

FAQ

What is the maximum allowable gate-source voltage for IAUC45N04S6N070HATMA1?

The absolute maximum gate-source voltage is ±20 V, with recommended operating range of -4 V to +15 V for reliable long-term performance. Exceeding ±20 V risks irreversible oxide damage. Gate drive circuits must include clamping (e.g., Zener diodes) to prevent transients during hot-plug or load dump events in automotive environments.

Does IAUC45N04S6N070HATMA1 support Kelvin source configuration for current sensing?

No, this device does not feature a dedicated Kelvin source pin. Its single-source terminal (pin 7) serves both power and signal return functions. For accurate high-side current sensing, external shunt resistors or isolated current sensors are required - unlike Infineon's newer TOLL-packaged variants that integrate separate sense pins.

Can IAUC45N04S6N070HATMA1 be used in parallel configurations?

Yes, the device supports paralleling due to its positive temperature coefficient of R_DS(on) (increases with junction temperature), which promotes natural current sharing. Layout must ensure matched trace lengths and thermal coupling; use of external gate resistors ≥5 Ω per device is recommended to suppress oscillation during turn-on/turn-off transitions.

What is the typical reverse recovery charge (Q_rr) of the integrated body diode?

The typical reverse recovery charge is 6 nC under conditions of V_R = 20 V, I_F = 45 A, and di_F/dt = 100 A/µs. This value is measured at T_j = 25 °C and decreases slightly at elevated temperatures - enabling predictable freewheeling behavior in synchronous rectifier and H-bridge topologies.
