Product details

Overview

IPG20N04S412ATMA1 from Infineon Technologies is a dual-channel AEC-Q101-qualified N-channel enhancement-mode MOSFET in PG-TDSON-8 package, rated for 40 V V_DS, 12.2 mΩ R_DS(on) at 10 V V_GS, and 20 A continuous drain current per channel. It operates up to 175 °C, features 100% single-pulse avalanche testing, and is optimized for automotive body electronics and high-efficiency DC-DC converters.

For engineers reviewing the IPG20N04S412ATMA1 datasheet, IPG20N04S412ATMA1 pinout, IPG20N04S412ATMA1 application, or IPG20N04S412ATMA1 equivalent, key selection criteria include its 3.7 K/W junction-to-case thermal resistance, 14–18 nC total gate charge, 1130–1470 pF input capacitance, and integrated freewheeling diode with 0.9–1.3 V forward voltage at 17 A.

Technical Context

This dual N-channel MOSFET uses Infineon's OptiMOS™-T2 silicon technology to deliver low conduction and switching losses in automotive-grade packaging. Its gate threshold voltage (2.0–4.0 V) enables robust TTL/CMOS-level drive compatibility, while the 5.5 V gate plateau voltage supports stable turn-on under varying load conditions.

The device integrates a co-packaged Schottky-like body diode with 32 ns reverse recovery time and 25 nC Q_rr, enabling efficient synchronous rectification and flyback operation. Thermal performance is validated with MSL1 rating (260 °C peak reflow) and 6 cm² PCB copper area requirement for specified R_thJA = 60 K/W.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
IPG20N04S4L12ATMA1	Logic-level gate (V_GS(th) = 1.0–2.5 V); same R_DS(on), package, and avalanche rating	Preferred for 3.3 V MCU-driven systems where 10 V gate drive is unavailable	Select when driving from low-voltage microcontrollers without level-shifting circuitry
IRF7341PBF	Higher R_DS(on) (24 mΩ), lower Q_g (12 nC), non-AEC-Q101, SO-8 package	Suitable for industrial non-automotive DC-DC and motor control where qualification is not required	Choose for cost-sensitive non-automotive designs needing smaller gate drive energy

Compared with IPG20N04S412ATMA1, the logic-level IPG20N04S4L12ATMA1 reduces system BOM count in 3.3 V domains, while IRF7341PBF trades automotive reliability for lower gate charge in commercial applications - neither offers identical thermal or qualification profile.

FAQ

What is the maximum allowable junction temperature during continuous operation?

The absolute maximum operating junction temperature is +175 °C, validated per AEC-Q101 stress testing. Continuous operation at this limit requires full thermal derating per the Safe Operating Area (SOA) curves on page 4 of the datasheet, with junction-to-case thermal resistance held at ≤3.7 K/W via proper PCB copper layout and heatsinking.

Does IPG20N04S412ATMA1 support parallel operation of both channels?

Yes - both channels share common drain terminals (pins 1,2,3,4,7,8) and have independent sources (pins 5 and 6) and gates (unlabeled but assigned per channel). Parallel use is supported for higher current capability, provided matched gate drive and symmetric PCB layout minimize current imbalance and thermal runaway.

Is the body diode suitable for continuous freewheeling in buck converters?

Yes - the integrated body diode is rated for 20 A continuous forward current and 80 A pulsed current per channel. Its 0.9–1.3 V V_SD at 17 A and 32 ns t_rr make it suitable for synchronous rectification in buck converters up to 500 kHz, though external Schottky diodes may be preferred for ultra-low V_F at light loads.

How is avalanche ruggedness verified for this part?

Avalanche ruggedness is confirmed by 100% single-pulse testing at I_D = 10 A, yielding E_AS = 80 mJ. Test conditions follow JEDEC JESD24-11, with energy measured across the full V_DS–I_D trajectory. This validates safe operation during inductive turn-off events such as solenoid or motor coil de-energization.
