Product details
Overview
IPI04N03LA from Infineon Technologies is a 25 V, 4.2 mΩ N-channel logic-level Power MOSFET in PG-TO262-3 package, optimized for high-frequency DC/DC converters and synchronous rectification. It delivers 80 A continuous drain current at TC = 25 °C, features 1.4 K/W junction-to-case thermal resistance, and supports 175 °C operation with dv/dt ruggedness up to 6 kV/μs.
For engineers reviewing the IPI04N03LA datasheet, IPI04N03LA pinout, IPI04N03LA application, or IPI04N03LA equivalent, key selection criteria include RDS(on) at 4.5 V gate drive, gate charge (Qg = 24–32 nC), avalanche energy (EAS = 290 mJ), and thermal performance in TO262-3 mounting configurations.
Technical Context
This OptiMOS®2 device uses trench-gate silicon technology to achieve low RDS(on) × Qg figure-of-merit (FOM) for efficient switching in hard-switched and resonant topologies. Its logic-level gate threshold (VGS(th) = 1.2–2.0 V typ.) enables direct drive from 3.3 V or 5 V controllers without level-shifting.
The MOSFET integrates a robust body diode with Qrr = 15 nC and VSD = 0.96–1.2 V at 80 A, supporting synchronous rectification in buck, boost, and LLC converters. Its 6 kV/μs dv/dt rating ensures immunity to parasitic turn-on in high-dI/dt environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 25 V - Maximum blocking voltage for 12 V input rail systems with margin |
| RDS(on) max | 4.2 mΩ @ VGS = 10 V - Enables <1 W conduction loss at 80 A in thermally optimized layouts |
| ID cont. | 80 A @ TC = 25 °C - Limited by bondwire; requires heatsink for sustained current |
| Qg | 24–32 nC - Determines gate driver power requirement and switching speed trade-off |
| EAS | 290 mJ - Supports unclamped inductive switching in converter primary-side snubbers |
| RthJC | 1.4 K/W - Enables precise junction temperature estimation from case measurement |
| dv/dt rating | 6 kV/μs - Prevents false turn-on during fast voltage transients in high-side switching |
Pinout & Package
PG-TO262-3 package: isolated tab (drain), 3-pin through-hole outline with drain-connected metal tab for thermal and electrical connection. Pin 1 = Gate, Pin 2 = Drain (tab), Pin 3 = Source.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Gate) | Control terminal | Accepts logic-level gate drive; low input capacitance (Ciss = 2915–3877 pF) reduces driver loading |
| Pin 2 (Drain / Tab) | High-current output node | Electrically and thermally connected to metal tab; must be mounted to heatsink with insulating pad if isolation required |
| Pin 3 (Source) | Reference node for gate drive | Serves as return path for gate current and load current; critical for stable gate loop layout |
Key Features
| Feature | Design Value |
|---|---|
| Logic-level gate drive | VGS(th) = 1.2–2.0 V enables direct interface with 3.3 V microcontrollers and PWM ICs |
| Low RDS(on) × Qg FOM | ~100 mΩ·nC - balances conduction and switching losses in 300–1000 kHz DC/DC designs |
| 175 °C rated junction | Supports operation in sealed enclosures or high-ambient industrial environments without derating |
| Robust body diode | Qrr = 15 nC and soft recovery reduce EMI and voltage overshoot in synchronous rectifier mode |
| Pb-free & RoHS compliant | Meets EU Directive 2011/65/EU; compatible with lead-free reflow and wave soldering processes |

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 |
|---|---|---|---|
| IPP04N03LA | Identical die, PG-TO220-3 package; RthJC = 1.4 K/W same, but higher RthJA due to smaller footprint | Better suited for prototyping or lower-power designs where TO220 heatsinking suffices | Select when board space allows TO220 mounting and thermal budget permits higher RthJA |
| IPB04N03LA | Same OptiMOS®2 die in PG-TO252-3 (DPAK); RthJC = 2.5 K/W, lower current rating (60 A) | Targeted at space-constrained SMT applications with moderate thermal demand | Choose for surface-mount assembly where TO262-3 through-hole is not feasible |
Compared with IPP04N03LA and IPB04N03LA, IPI04N03LA offers identical electrical performance in a PG-TO262-3 package optimized for high-current, high-reliability through-hole mounting with superior thermal coupling to large heatsinks.

FAQ
What is the maximum gate-source voltage for IPI04N03LA?
The absolute maximum gate-source voltage is ±20 V. Operation beyond ±15 V risks permanent gate oxide damage. For reliable logic-level drive, keep VGS between 4.5 V and 10 V; the gate plateau voltage is 3.3 V, confirming strong turn-on behavior at low drive levels.
Can IPI04N03LA be used in synchronous rectification without an external Schottky diode?
Yes. Its integrated body diode has Qrr = 15 nC and VSD = 0.96–1.2 V at 80 A and 25 °C, enabling direct use in synchronous rectifier configurations. No external diode is needed, though layout must minimize source inductance to avoid shoot-through during dead-time transitions.
How does thermal resistance differ between IPI04N03LA and IPP04N03LA?
Both share identical RthJC = 1.4 K/W, but IPI04N03LA's PG-TO262-3 package achieves lower effective RthJA (40 K/W with 6 cm² copper) versus IPP04N03LA's PG-TO220-3 (62 K/W same condition), due to larger thermal pad area and improved heatsink contact geometry.
Is IPI04N03LA suitable for automotive AEC-Q101 qualification?
No. While rated for 175 °C operation and JEDEC-qualified for target applications, IPI04N03LA is not AEC-Q101 qualified. For automotive-grade use, consider Infineon's AEC-Q101-qualified OptiMOS™ 5 variants such as IPB04N03L3 G, which offer similar RDS(on) with full automotive qualification.
