Product details
Overview
IPB04N03LA from Infineon Technologies is an N-channel logic-level Power MOSFET in PG-TO263 package, rated for 25 V VDS, 3.9 mΩ RDS(on) (max) at VGS = 10 V, 80 A continuous drain current, and 175 °C operation-designed for high-frequency DC/DC converters in server VRMs and POL modules.
For engineers reviewing the IPB04N03LA datasheet, IPB04N03LA pinout, IPB04N03LA application, or IPB04N03LA equivalent, key selection criteria include gate charge (Qg = 24–32 nC), dv/dt rating (6 kV/µs), thermal resistance (RthJC = 1.4 K/W), and synchronous FET gate drive compatibility (Qg(sync) = 20–27 nC).
Technical Context
This OptiMOS®2 device uses trench-gate superjunction technology to achieve low RDS(on) × Qg figure-of-merit (FOM), enabling high-efficiency switching in hard-switched and synchronous rectifier topologies. Its 1.4 K/W junction-to-case thermal resistance supports high-power density PCB layouts with minimal copper area.
The MOSFET features a fully rated avalanche capability (EAS = 290 mJ), dv/dt immunity up to 6 kV/µs, and gate threshold voltage (VGS(th) = 1.2–2.0 V) optimized for 3.3 V and 5 V logic-level gate drivers-ensuring robust turn-on under low-voltage control conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 25 V - Maximum blocking voltage for 12 V input bus applications with margin |
| RDS(on) max | 3.9 mΩ @ VGS = 10 V - Enables <1 W conduction loss at 80 A in compact VRM designs |
| Qg | 24–32 nC - Determines gate driver power requirement and switching speed in 300–1000 kHz converters |
| RthJC | 1.4 K/W - Allows direct heatsink mounting for thermal management without thermal vias |
| EAS | 290 mJ - Supports single-pulse inductive energy absorption without failure in non-clamped circuits |
| dv/dt rating | 6 kV/µs - Ensures reliable operation in fast-switching synchronous buck converters with steep edge rates |
| Tj max | 175 °C - Permits sustained operation in high-ambient industrial and telecom power systems |
Pinout & Package
PG-TO263-3 (D²PAK) package with isolated tab (drain-connected), standard 3-pin layout: Pin 1 = Gate, Pin 2 = Drain (tab), Pin 3 = Source.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

|---|---|
| Logic-level gate drive | Operates fully enhanced at VGS ≥ 4.5 V-compatible with 3.3 V microcontrollers and dedicated POL gate drivers |
| Low RDS(on) × Qg FOM | ~100 Ω·nC - balances conduction and switching losses for optimal efficiency at 500 kHz |
| Enhanced dv/dt immunity | Rated to 6 kV/µs - prevents spurious turn-on in high-di/dt synchronous rectifier configurations |
| 175 °C rated junction | Enables derating-free operation in sealed enclosures or high-ambient telecom base stations |
| Integrated body diode | VSD = 0.96–1.2 V @ 80 A - supports bidirectional current in synchronous buck and OR-ing applications |

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel logic-level power MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IRL3803PbF | RDS(on) = 4.5 mΩ @ 10 V; Qg = 42 nC; RthJC = 1.7 K/W | Higher gate charge increases driver loss and limits max switching frequency to ~300 kHz | Preferred where cost sensitivity outweighs efficiency and thermal performance requirements |
| STL220N3LLH6 | RDS(on) = 3.0 mΩ @ 10 V; Qg = 48 nC; Tj max = 175 °C; PG-TSDSON8 package | Smaller footprint but higher thermal resistance (RthJC = 2.5 K/W); requires careful PCB thermal design | Selected when board space is constrained and thermal vias can be deployed for heat spreading |
Compared with IRL3803PbF and STL220N3LLH6, IPB04N03LA delivers superior FOM (RDS(on) × Qg) and lowest junction-to-case thermal resistance-making it optimal for thermally limited, high-frequency POL and telecom DC/DC designs where efficiency and power density are prioritized.

FAQ
Is IPB04N03LA suitable for synchronous rectification in flyback converters?
Yes. With Qg(sync) = 20–27 nC at 0–5 V gate swing and VSD = 0.96–1.2 V at 80 A, it delivers low gate drive loss and reduced conduction loss versus Schottky diodes-enabling >2% efficiency gain in 300 kHz flyback designs operating at 12 V output.
What is the maximum recommended PCB copper area for thermal performance?
The datasheet specifies optimal performance with a 40 mm × 40 mm × 1.5 mm FR4 PCB and 6 cm² cooling area on one layer. Using this layout achieves RthJA = 40 K/W; reducing copper area increases junction temperature proportionally-designs must verify Tj ≤ 175 °C under worst-case load and ambient.
Does IPB04N03LA require a gate resistor for stability?
A gate resistor (typically 2.7 Ω) is recommended per Figure 16 in the datasheet to dampen ringing and control switching speed. This value balances EMI reduction and switching loss-lower values increase dv/dt stress; higher values raise turn-on delay and conduction time in high-frequency operation.
Can IPB04N03LA replace older OptiMOS®1 devices in existing designs?
Yes-pin-compatible with IPB03N03LA and IPB02N03LA in PG-TO263 package. It offers lower RDS(on) (3.9 mΩ vs. 4.5/5.2 mΩ) and improved thermal resistance (1.4 K/W vs. 1.6/1.8 K/W), enabling direct drop-in upgrades that reduce conduction loss by up to 15% without layout changes.
