Product details

Overview

IPI90N04S402AKSA1 from Infineon Technologies is an AEC-Q101 qualified N-channel enhancement-mode MOSFET in PG-TO262-3-1 package, rated for 40 V V_DS, 90 A continuous drain current at T_C = 100 °C, and 2.1 mΩ max R_DS(on) (SMD version). It operates up to 175 °C junction temperature and is 100% avalanche tested for automotive power switching in high-current DC-DC converters and motor control stages.

For engineers reviewing the IPI90N04S402AKSA1 datasheet, IPI90N04S402AKSA1 pinout, IPI90N04S402AKSA1 application, or IPI90N04S402AKSA1 equivalent, key selection criteria include its 1.0 K/W R_thJC, 91–118 nC total gate charge, 7250–9430 pF input capacitance, and SMD-compatible thermal performance on 6 cm² PCB copper area.

Technical Context

This OptiMOS®-T2 device uses trench-based silicon technology optimized for low conduction and switching losses in 12 V automotive systems. Its gate threshold voltage (2.0–4.0 V) enables robust TTL/CMOS-level drive compatibility, while the 5.8 V gate plateau voltage supports stable Miller region control during hard-switching.

The integrated body diode delivers 90 A continuous forward current with 0.9–1.3 V forward voltage at 90 A and 25 °C, and exhibits 53 ns reverse recovery time under 20 V reverse bias and 100 A/µs di/dt - critical for synchronous rectification and freewheeling in buck and half-bridge topologies.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	40 V - Maximum blocking voltage compatible with 12 V automotive battery systems including load dump transients.
R_DS(on) max	2.1 mΩ (SMD version) - Enables <1.9 W conduction loss at 90 A, reducing heatsink requirements in space-constrained modules.
I_D cont.	90 A @ T_C = 100 °C - Supports high-current motor phases and starter solenoid drivers without derating in engine bay environments.
E_AS	475 mJ - Confirmed single-pulse avalanche energy rating ensures reliability during inductive turn-off events in relay/snubberless designs.
Q_g	91–118 nC - Gate drive energy requirement directly determines driver IC selection and switching speed trade-offs in 100–500 kHz SMPS.
t_r/t_f	13 ns / 26 ns - Fast edge rates minimize switching transition losses but require careful PCB layout to suppress EMI in safety-critical ECUs.
T_j max	175 °C - Extended thermal range allows operation in proximity to exhaust manifolds or under-hood power distribution units.

Pinout & Package

Package: PG-TO262-3-1 - 3-pin straight-leaded variant of TO-262, with isolated drain tab for direct heatsink mounting and lead-free (RoHS-compliant) finish. MSL1 rated for peak reflow up to 260 °C.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Source)	Power return path for channel current	Low-inductance connection point for Kelvin source sensing or current monitoring shunt placement.
Pin 2 (Gate)	Control electrode for channel modulation	Requires <100 nF local decoupling and series resistor (3.5 Ω typical) to damp ringing during fast switching.
Pin 3 (Drain)	Main power output terminal	Internally connected to metal tab; must be soldered to ≥6 cm² copper pour for R_thJA = 40 K/W thermal performance.

Key Features

Feature	Design Value
AEC-Q101 qualification	Validated for automotive powertrain and chassis applications per stress test requirements including HTOL, TC, and UHAST.
100% avalanche tested	Each unit subjected to single-pulse I_AS = 90 A at V_DS = 40 V, ensuring field robustness against inductive kickback.
Green Product (RoHS)	Lead-free termination and halogen-free molding compound compliant with EU Directive 2011/65/EU and JESD204B.
Optimized C_iss/C_oss ratio	7250–9430 pF C_iss vs. 1630–2120 pF C_oss enables ZVS capability in resonant LLC converters above 200 kHz.
Low Q_gd/Q_g ratio	12–28 nC Q_gd / 91–118 nC Q_g ≈ 0.11–0.24 - improves Miller immunity and reduces risk of spurious turn-on in high-dV/dt environments.

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
IPB90N04S4-02	PG-TO263-3-2 package; identical R_DS(on), Q_g, and avalanche rating; 0.1 K/W lower R_thJC.	Suitable for surface-mount assembly with thermal pad soldering; requires different footprint and stencil design.	Select when board space permits SMD mounting and automated reflow is preferred over through-hole assembly.
IPP90N04S4-02	PG-TO220-3-1 package; same die, higher R_thJC = 1.1 K/W; no MSL1 reflow rating.	Used in legacy through-hole power modules where mechanical retention and manual soldering are standard.	Choose for cost-sensitive industrial controls where automotive qualification is not required and thermal margin is >15 K.

Compared with IPB90N04S4-02 and IPP90N04S4-02, IPI90N04S402AKSA1 offers optimal balance of AEC-Q101 compliance, through-hole manufacturability, and thermal performance - making it ideal for new automotive ECU designs requiring both reliability and assembly flexibility.

FAQ

Is IPI90N04S402AKSA1 pin-compatible with IPB90N04S4-02?

No - IPI90N04S402AKSA1 uses PG-TO262-3-1 (straight-leaded) packaging, while IPB90N04S4-02 uses PG-TO263-3-2 (surface-mount with thermal pad). Pin numbering is identical (G-S-D), but mechanical mounting, thermal interface, and PCB footprint differ significantly. Direct substitution requires board redesign.

What is the maximum recommended gate resistor value for 300 kHz switching?

For reliable 300 kHz operation with minimal overshoot, a 3.5 Ω series gate resistor is specified in the datasheet under V_DD = 20 V, I_D = 90 A conditions. Increasing beyond 5 Ω risks excessive t_d(on) (>23 ns) and elevated switching losses; values below 2 Ω require active gate driving to avoid ringing.

Does this MOSFET support synchronous rectification in a buck converter?

Yes - its 0.9–1.3 V body diode forward voltage at 90 A and 53 ns t_rr enable efficient synchronous rectification when paired with complementary gate timing. However, external low-V_F Schottky diodes may still be preferred in ultra-low-voltage outputs (<1.2 V) due to intrinsic diode voltage drop limitations.

Can IPI90N04S402AKSA1 be used in non-automotive industrial applications?

Yes - while AEC-Q101 qualified, its 175 °C T_j, 40 V rating, and 90 A current capability make it suitable for industrial motor drives, UPS inverters, and high-power LED drivers. RoHS compliance and 100% avalanche testing provide added robustness beyond standard industrial requirements.
