Product details
Overview
IPB80N04S303ATMA1 from Infineon Technologies is an N-channel enhancement-mode automotive-qualified MOSFET in PG-TO263-3-2 package, rated for 40 V VDS, 80 A continuous drain current at TC = 25 °C, and ultra-low 2.5–3.2 mΩ RDS(on) (SMD version). It operates up to 175 °C, is AEC-Q101 qualified, 100% avalanche tested, and used in high-current DC-DC converters and motor control stages.
For engineers reviewing the IPB80N04S303ATMA1 datasheet, IPB80N04S303ATMA1 pinout, IPB80N04S303ATMA1 application, or IPB80N04S303ATMA1 equivalent, key selection criteria include RDS(on) at 80 A/10 V, thermal resistance (RthJC = 0.8 K/W), avalanche energy (EAS = 526 mJ), and gate charge (Qg = 83–110 nC) for switching loss optimization.
Technical Context
This OptiMOS®-T device uses trench-based silicon technology optimized for low conduction and switching losses in high-efficiency power stages. Its gate threshold voltage (2.1–4.0 V) enables robust 10 V gate drive compatibility while maintaining noise immunity, and its integrated body diode supports synchronous rectification with trr = 46 ns and Qrr = 73 nC.
The MOSFET features a thermally enhanced SMD package (PG-TO263-3-2) with direct-drain copper pad for low-inductance PCB mounting. Its dynamic parameters-including Ciss = 5600–7300 pF, Coss = 1540–2000 pF, and Crss = 240–350 pF-are specified at VGS = 0 V and f = 1 MHz, supporting accurate snubber and gate driver design.

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel 40 V power MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IPB80N04S403ATMA1 | Lower RDS(on) (2.0–2.6 mΩ), higher Qg (120–150 nC), same package | Better conduction loss but higher switching loss at >200 kHz | Select when thermal budget dominates over switching frequency constraints |
| IRF8721TRPBF | Higher RDS(on) (3.8 mΩ), lower Qg (25 nC), SO-8 package | Limited to ≤30 A continuous; unsuitable for automotive under-hood use | Select only for cost-sensitive, low-power industrial SMPS where AEC-Q101 is not required |
Compared with IPB80N04S303ATMA1, the IPB80N04S403ATMA1 improves conduction efficiency at the expense of gate drive strength and switching speed, while the IRF8721TRPBF trades off current rating, ruggedness, and qualification for footprint and cost reduction in non-automotive designs.

FAQ
What is the maximum allowable gate-source voltage for IPB80N04S303ATMA1?
The absolute maximum gate-source voltage is ±20 V. Operation above +15 V or below −10 V risks permanent gate oxide damage. Recommended drive is +10 V for full enhancement and minimal RDS(on), with fast fall-time (<50 ns) to avoid Miller-induced false turn-on during switching transitions.
Is IPB80N04S303ATMA1 suitable for synchronous rectification in a 48 V buck converter?
Yes. Its low RDS(on) (2.5 mΩ typ.), fast body diode (trr = 46 ns), and low Qrr (73 nC) make it well-suited for synchronous rectification at 48 V input and up to 80 A output. Layout must minimize source inductance and ensure Kelvin source connection for accurate gate drive referencing.
How does the thermal resistance RthJC = 0.8 K/W translate to practical PCB layout requirements?
This value assumes direct thermal coupling between the exposed drain pad and a ≥6 cm² copper area on 1.5 mm FR4 PCB, vertically mounted in still air. To achieve rated 80 A continuous current, the PCB copper must be solid (70 µm thick), unbroken, and thermally connected to a heatsink or ambient airflow path-otherwise derating to ≤50 A is required.
Does IPB80N04S303ATMA1 require external avalanche protection in motor drive applications?
No. It is 100% factory-tested for single-pulse avalanche energy (EAS = 526 mJ at 80 A), making external clamping diodes unnecessary for typical inductive load switching. However, repetitive avalanche operation is not guaranteed and should be avoided through proper snubber design and layout.
