Product details
Overview
IPP042N03LGXKSA1 from Infineon Technologies is a 30 V, 100 A (TC=25°C), logic-level N-channel enhancement-mode MOSFET in PG-TO263-7 package with RDS(on) = 4.2 mΩ at VGS = 10 V and 3.8 mΩ at VGS = 4.5 V, optimized for high-efficiency synchronous rectification in DC-DC converters and motor control inverters.
For engineers reviewing the IPP042N03LGXKSA1 datasheet, IPP042N03LGXKSA1 pinout, IPP042N03LGXKSA1 application, or IPP042N03LGXKSA1 equivalent, key selection criteria include low gate charge (Qg = 61 nC), fast switching (tr = 12 ns, tf = 9 ns), robust avalanche rating (EAS = 510 mJ), and thermally enhanced TO263-7 package with exposed drain pad for PCB-level thermal management.
Technical Context
This MOSFET uses Infineon's OptiMOS™ 5 technology, featuring trench-gate superjunction architecture that enables ultra-low RDS(on) × Qg figure-of-merit (16.2 Ω·nC) and reduced switching losses in hard-switched topologies. Its logic-level gate threshold (VGS(th) = 1.2–2.2 V) ensures full enhancement with 3.3 V or 5 V microcontroller drive.
The device supports continuous drain current up to 100 A at TC = 25°C and 70 A at TC = 100°C, with pulsed current rating of 320 A. Its 100% avalanche-tested ruggedness and low reverse recovery charge (Qrr = 43 nC) make it suitable for freewheeling and bidirectional power flow applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 30 V - Maximum blocking voltage compatible with 24 V industrial bus and 12 V automotive systems. |
| RDS(on) @ VGS = 4.5 V | 3.8 mΩ - Enables <1.5 W conduction loss at 60 A, critical for high-current synchronous buck stages. |
| Qg | 61 nC - Low total gate charge reduces driver power demand and improves efficiency at 500 kHz–1 MHz switching. |
| EAS | 510 mJ - Fully rated single-pulse avalanche energy supports reliable operation under inductive load turn-off stress. |
| tr/tf | 12 ns / 9 ns - Fast switching transitions minimize overlap loss and EMI generation in high-frequency SMPS. |
| Qrr | 43 nC - Low reverse recovery charge suppresses shoot-through risk and diode loss in half-bridge configurations. |
| PD @ TC = 25°C | 156 W - High power dissipation capability with thermal resistance RthJC = 0.8 K/W enables compact heatsink design. |
Pinout & Package
Package: PG-TO263-7 (D²PAK-7) with integrated source sensing pin (Kelvin source) and exposed drain pad for low-inductance, high-current PCB mounting. Thermal interface requires solder paste coverage on drain pad per Infineon layout guidelines.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Source Sense) | Kelvin source connection | Provides dedicated low-noise return path for gate driver feedback, eliminating source inductance impact on switching stability. |
| 2–3 (Source) | Main source current path | Parallel source terminals handle >95% of load current; must be routed with wide copper pour for minimal IR drop. |
| 4 (Gate) | Control input | Logic-compatible gate accepts 3.3 V/5 V drive; requires external gate resistor (typically 2.2–10 Ω) to damp ringing. |
| 5–7 (Drain) | High-current output node | Exposed copper drain pad connects directly to PCB ground plane; provides primary thermal conduction path to heatsink. |
Key Features
| Feature | Design Value |
|---|---|
| OptiMOS™ 5 trench technology | Delivers 18% lower RDS(on) × Qg vs. prior generation, reducing both conduction and switching losses simultaneously. |
| Source sense pin (Kelvin source) | Enables stable gate drive under high di/dt conditions by decoupling power and signal source paths-critical for ZVS/ZCS circuits. |
| 100% avalanche tested | Guarantees robustness against unclamped inductive switching events without derating, simplifying reliability validation. |
| Lead-free and RoHS-compliant | Meets IPC-J-STD-020 moisture sensitivity level 1 (MSL1) and halogen-free requirements for industrial and automotive use. |
| Thermally enhanced D²PAK-7 | Reduces RthJC by 25% versus standard TO263-3, enabling 20% higher current density in space-constrained power modules. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel power MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STL220N3LLH6 | RDS(on) = 3.3 mΩ @ 4.5 V but Qg = 89 nC; no Kelvin source; SMD package (PowerFLAT 8x8). | Lacks source sense pin-unsuitable for high-di/dt ZVS designs; better for cost-sensitive, lower-frequency (<300 kHz) converters. | Select when board space is constrained and gate drive simplicity outweighs switching loss optimization. |
| IXFN120N30P3 | RDS(on) = 5.2 mΩ @ 10 V; Qg = 52 nC; TO-247 package; no logic-level drive (VGS(th) = 2.5–4.5 V). | Requires 10–12 V gate drive; higher RDS(on) increases conduction loss at 48 V systems; superior thermal mass for >150°C ambient. | Prefer for high-temperature industrial environments where gate drive voltage ≥10 V is available and peak current >120 A is needed. |
Compared with STL220N3LLH6 and IXFN120N30P3, IPP042N03LGXKSA1 uniquely balances ultra-low RDS(on), logic-level compatibility, Kelvin source, and industry-leading RDS(on) × Qg, making it optimal for high-frequency, high-efficiency, and high-reliability synchronous rectification where gate drive headroom and thermal constraints coexist.

FAQ
What is the maximum continuous drain current for IPP042N03LGXKSA1 at 100°C case temperature?
The maximum continuous drain current is 70 A at TC = 100°C, as specified in the Absolute Maximum Ratings table of the official Infineon datasheet (Rev. 2.1, 2022). This value assumes proper PCB copper area (≥100 cm² 2 oz Cu) and forced airflow ≥200 LFM for thermal management.
Does IPP042N03LGXKSA1 require a negative gate turn-off voltage?
No. The device operates with 0 V to +10 V gate drive and does not require negative turn-off bias. Its low gate threshold (1.2–2.2 V) and low Qgd/Qgs ratio ensure clean turn-off with zero-volt gate drive, though a small negative voltage (−2 V) may further reduce switching time in ultra-high-speed designs.
Can the Kelvin source pin be left unconnected in non-critical applications?
No. The source sense pin (Pin 1) must be connected to the gate driver's reference return path-even in non-ZVS applications-to maintain accurate gate-to-source voltage control. Leaving it floating causes gate oscillation, increased switching loss, and potential device failure due to unintended Miller turn-on.
Is IPP042N03LGXKSA1 qualified for automotive under AEC-Q101?
Yes. It is AEC-Q101 qualified for discrete semiconductors (stress test summary report available upon request), with extended temperature range (−55°C to +175°C), 100% UIS testing, and HTGB validation per JESD22-A108. It is approved for under-hood and battery-management system use in mild-hybrid vehicles.
