Product details

Overview

IPI80N04S404AKSA1 from Infineon Technologies is an AEC-Q101 qualified N-channel enhancement-mode power MOSFET in PG-TO262-3-1 package, rated for 40 V V_DS, 4.2 mΩ R_DS(on) (max) at 10 V V_GS, 80 A continuous drain current, and 175 °C operating temperature-designed for high-efficiency 12 V automotive DC-DC converters and motor control stages.

For engineers reviewing the IPI80N04S404AKSA1 datasheet, IPI80N04S404AKSA1 pinout, IPI80N04S404AKSA1 application, or IPI80N04S404AKSA1 equivalent, key selection criteria include its 2.1 K/W junction-to-case thermal resistance, 100 mJ single-pulse avalanche energy, 3.9–4.2 mΩ typical R_DS(on) (SMD version), and ±20 V gate-source voltage rating under automotive-grade reliability constraints.

Technical Context

This OptiMOS™-T2 device uses trench-gate superjunction technology to achieve low conduction loss while maintaining fast switching performance. Its 3.9 mΩ typical R_DS(on) at 10 V gate drive enables high-current operation with minimal I²R heating in compact SMD layouts.

The MOSFET features fully characterized dynamic parameters including 2650–3440 pF input capacitance, 20–46 pF reverse transfer capacitance, and 33–43 nC total gate charge-enabling precise gate driver sizing for PWM frequencies up to 500 kHz in synchronous buck topologies.

Key Specifications

V_DS	40 V - Maximum blocking voltage compatible with 12 V automotive battery systems with transient margin.
R_DS(on) max	4.2 mΩ at V_GS = 10 V, T_j = 25 °C - Enables ≤3.4 W conduction loss at 80 A, critical for thermally constrained modules.
I_D continuous	80 A at T_C = 25 °C - Supported by robust bondwire construction and 2.1 K/W R_thJC.
E_AS	100 mJ (I_D = 40 A) - Confirmed single-pulse avalanche ruggedness for inductive load switching.
Q_g	33–43 nC - Determines gate driver peak current requirement (~2.5 A for 15 ns rise time with 3.5 Ω R_G).
T_j max	+175 °C - Qualified for under-hood automotive environments per AEC-Q101.
V_GS(th)	2.0–4.0 V - Ensures reliable turn-on with standard 3.3 V or 5 V logic-level gate drivers when used with appropriate margin.

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
IPB80N04S4-04	Same die, PG-TO263-3-2 package with exposed drain pad; 3.9 mΩ typical R_DS(on) (SMD).	Better thermal performance on PCB (R_thJA = 40 K/W with 6 cm² copper) but requires surface-mount assembly.	Select for higher-density SMD designs where thermal management via PCB copper is preferred over through-hole mounting.
IPP80N04S4-04	Same die, PG-TO220-3-1 package; identical R_DS(on) and ratings but higher R_thJA (62 K/W).	Suitable for prototyping and lower-volume through-hole production; less effective thermal spreading than TO262/TO263 variants.	Select for manual assembly, legacy board compatibility, or cost-sensitive non-automotive industrial use.

Compared with IPB80N04S4-04 and IPP80N04S4-04, the IPI80N04S404AKSA1 offers a balanced trade-off: TO262's mechanical robustness and ease of through-hole rework, plus thermal performance closer to TO263 than TO220-making it optimal for volume automotive production with mixed-technology PCBs.

FAQ

What is the maximum gate-source voltage rating for safe operation?

The absolute maximum V_GS is ±20 V. Operation beyond this risks irreversible gate oxide breakdown. For reliable 12 V gate drive, a 15 V clamp or Zener protection is recommended-especially in noisy automotive environments where transients may exceed 12 V rail.

Does this MOSFET require a gate resistor, and what value is recommended?

Yes-a series gate resistor is required to control dV/dt and prevent oscillation. With 33–43 nC Q_g and typical driver output impedance, a 3.5 Ω resistor achieves ~12 ns rise time per datasheet test conditions; values between 2.2 Ω and 10 Ω balance switching loss and EMI.

How is thermal performance affected when mounted without a heatsink?

Without external heatsinking, thermal performance relies entirely on PCB copper area. With 6 cm² of 70 µm copper on FR4, R_thJA is 40 K/W-allowing ~45 W dissipation at ΔT = 150 K. Below that area, derating is mandatory; at 1 cm², R_thJA exceeds 100 K/W.

Is the body diode suitable for freewheeling in synchronous rectification?

Yes-the integrated Schottky-like body diode has V_SD = 0.9–1.3 V at 80 A and t_rr = 39 ns, making it viable for synchronous rectification in buck converters up to ~300 kHz. However, external Schottky diodes remain preferred for ultra-low-loss or high-frequency (>500 kHz) designs.
