Product details
Overview
IPA041N04NGXKSA1 from Infineon Technologies is an N-channel enhancement-mode MOSFET optimized for high-efficiency DC/DC converters, featuring 40 V VDS, 4.1 mΩ RDS(on) max at VGS = 10 V, 70 A continuous drain current (TC = 25 °C), and TO-220-FP package with isolated drain tab. It serves as a primary synchronous rectifier or high-side switch in 12 V–24 V industrial power supplies.
For engineers reviewing the IPA041N04NGXKSA1 datasheet, IPA041N04NGXKSA1 pinout, IPA041N04NGXKSA1 application, or IPA041N04NGXKSA1 equivalent, key selection criteria include RDS(on) × Qg figure-of-merit, avalanche ruggedness (EAS = 70 mJ), thermal resistance (RthJC = 4.3 K/W), and gate plateau voltage (5.1 V) for PWM timing margin analysis.
Technical Context
This OptiMOS™3 device uses trench-gate superjunction technology to achieve low conduction loss while maintaining fast switching speed. Its 3.5 mΩ typical RDS(on) and 42–56 nC total gate charge enable high-frequency operation in synchronous buck converters up to 1 MHz.
The MOSFET integrates a robust body diode with 19 nC reverse recovery charge (Qrr) and 0.87 V forward voltage (VSD) at 29 A, supporting efficient hard-switched and quasi-resonant topologies without external freewheeling diodes.

Pinout & Package
IPA041N04NGXKSA1 is housed in PG-TO220-FP (TO-220 Full-Pak) package with electrically isolated drain tab for simplified heatsinking and enhanced creepage/clearance. The plastic body provides reinforced insulation between drain and source terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Gate) | Control input | Receives PWM signal; requires <2.4 Ω external gate resistor to limit dV/dt-induced shoot-through risk |
| Pin 2 (Drain) | High-side power node | Connected to drain tab; electrically isolated for direct heatsink mounting without insulator |
| Pin 3 (Source) | Power return / reference | Serves as local ground reference for gate driver; ties to PCB source plane or low-side switch source |
Key Features

| Optimized FOM (RDS(on) × Qg) | ≤0.17 Ω·nC - Reduces combined conduction + switching loss in 300–500 kHz DC/DC designs |
| 100% Avalanche Tested | Single-pulse EAS = 70 mJ - Guarantees ruggedness against inductive load transients without derating |
| Low Qgd/Qg ratio | 5.3/56 ≈ 9.5% - Minimizes Miller-induced gate oscillation during high-dV/dt commutation |
| Pb-free & Halogen-free | RoHS-compliant plating per IEC61249-2-21 - Meets IPC-J-STD-020 moisture sensitivity level 1 (MSL1) |

FAQ
What is the maximum allowable gate-source voltage for IPA041N04NGXKSA1?
The absolute maximum gate-source voltage is ±20 V. Operation above +12 V or below –5 V risks permanent gate oxide damage. For reliable PWM control, maintain VGS between 4.5 V (to ensure full enhancement) and 10 V (to avoid excessive gate current and overshoot).
Does IPA041N04NGXKSA1 require a gate resistor, and what value is recommended?
Yes, an external gate resistor is required to dampen ringing and control slew rate. With typical gate resistance of 1.6–2.4 Ω and 56 nC total gate charge, a 1.6 Ω resistor limits peak gate current to ~6.25 A and achieves ~16 ns turn-on delay, matching the datasheet test condition.
Can IPA041N04NGXKSA1 be used in linear (analog) mode for hot-swap or inrush limiting?
No - this MOSFET is not characterized or qualified for linear-mode operation. Its Safe Operating Area (SOA) curve shows limited DC capability beyond 10 A at VDS > 10 V, and thermal runaway risk increases rapidly above Tj = 125 °C in analog bias.
Is the drain tab electrically isolated from the source pin in IPA041N04NGXKSA1?
Yes - the TO-220-FP package features a fully isolated drain tab, allowing direct mounting to a grounded heatsink without insulating hardware. This reduces thermal resistance by eliminating thermal interface material layers and improves system-level EMI performance.
