Product details

Overview

IPI120N04S402AKSA1 from Infineon Technologies is a 40 V, 120 A N-channel enhancement-mode MOSFET in PG-TO262-3-1 package, AEC-qualified for automotive powertrain and body electronics, with 1.8 mΩ max R_DS(on) at V_GS = 10 V, 100% avalanche tested, and rated for 175 °C operation.

For engineers reviewing the IPI120N04S402AKSA1 datasheet, IPI120N04S402AKSA1 pinout, IPI120N04S402AKSA1 application, or IPI120N04S402AKSA1 equivalent, key selection criteria include continuous drain current at elevated case temperature, thermal resistance (R_thJC = 0.95 K/W), gate charge profile (Q_g = 103–134 nC), and integrated body diode performance (V_SD = 0.9–1.3 V at 100 A).

Technical Context

This OptiMOS®-T2 device uses trench-gate superjunction technology optimized for low conduction and switching losses in 12 V automotive systems. Its 1.8 mΩ R_DS(on) enables high-efficiency synchronous rectification and motor control, while the 480 A pulsed drain current supports short-term overload conditions.

The MOSFET features a fully characterized reverse diode with t_rr = 60 ns and Q_rr = 65 nC, enabling fast commutation in half-bridge configurations. Gate plateau voltage is fixed at 5.3 V, supporting robust drive with standard 5 V logic-level controllers.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	40 V - Maximum blocking voltage for 12 V battery rail applications including start-stop and load-dump protection.
R_DS(on) max	1.8 mΩ @ V_GS = 10 V - Enables <1.2 W conduction loss at 120 A, reducing heatsink requirements in high-current DC-DC converters.
I_D continuous	120 A @ T_C = 100 °C - Sustains full-rated current under engine bay thermal conditions without derating.
E_AS	480 mJ - Withstands single-pulse inductive energy in motor drive freewheeling without failure.
Q_g	103–134 nC - Determines gate driver power requirement and switching speed in PWM frequencies up to 100 kHz.
t_r/t_f	16/30 ns - Supports fast turn-on/turn-off for reduced switching losses in high-frequency SMPS designs.
V_GS(th)	2.0–4.0 V - Ensures reliable turn-on with automotive-grade 5 V microcontrollers and avoids false triggering near ground noise.

Pinout & Package

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
IPB120N04S4-02	Same die, PG-TO263-3-2 package with larger thermal pad and lower R_thJA (40 K/W vs. 62 K/W).	Better suited for space-constrained PCBs where top-side cooling is preferred over through-hole mounting.	Select when board layout permits SMD-only assembly and thermal management prioritizes PCB copper area over mechanical mounting.
IPP120N04S4-02	Same die, PG-TO220-3-1 package with insulated tab and higher R_thJA (62 K/W), no MSL1 reflow rating.	Designed for through-hole prototyping and legacy automotive modules requiring mechanical screw-mount heatsinks.	Select for manual assembly, repairability, or applications where isolation from chassis ground is required.

Compared with IPB120N04S4-02 and IPP120N04S4-02, IPI120N04S402AKSA1 offers identical electrical performance in a PG-TO262-3-1 package that balances SMT compatibility, thermal performance (R_thJC = 0.95 K/W), and mechanical robustness for automated production lines.

FAQ

What is the maximum allowable gate-source voltage for IPI120N04S402AKSA1?

The absolute maximum V_GS is ±20 V. Operation beyond this risks permanent gate oxide damage. For reliable long-term use, gate drive should be limited to 10–15 V during normal switching, with transient spikes clamped below 18 V using Zener diodes or active gate drivers.

Does IPI120N04S402AKSA1 include an integrated body diode, and what are its key parameters?

Yes, it features a monolithic body diode with forward voltage V_SD = 0.9–1.3 V at 100 A and 25 °C, reverse recovery time t_rr = 60 ns, and Q_rr = 65 nC. These values enable efficient freewheeling in half-bridge motor drives without external diode supplementation.

Can IPI120N04S402AKSA1 be used in synchronous rectification for 48 V mild-hybrid systems?

No - its 40 V V_DS rating is insufficient for 48 V nominal bus applications, which require ≥65 V breakdown voltage to accommodate load-dump transients. It is strictly intended for 12 V automotive systems per ISO 7637-2 and LV124 specifications.

What is the recommended PCB layout practice for thermal management of IPI120N04S402AKSA1?

Mount the drain-connected tab directly to ≥6 cm² of 70 µm thick copper on FR4 PCB, using multiple thermal vias (≥8 × 0.3 mm) to inner ground planes. Maintain >2 mm clearance between gate trace and high-dI/dt drain paths to prevent capacitive coupling-induced false turn-on.
