Product details
Overview
IPDH6N03LAG from Infineon Technologies is an N-channel logic-level OptiMOS®2 power MOSFET in PG-TO252-3-11 package, rated for 25 V VDS, 50 A continuous drain current at TC = 25 °C, and 6 mΩ max RDS(on) at VGS = 10 V. It delivers high-frequency switching performance in synchronous buck converters for server VRMs and telecom POL modules.
For engineers reviewing the IPDH6N03LAG datasheet, IPDH6N03LAG pinout, IPDH6N03LAG application, or IPDH6N03LAG equivalent, key selection criteria include its 2.1 K/W junction-to-case thermal resistance, 14–19 nC total gate charge, 175 °C maximum operating temperature, and JEDEC-qualified reliability for industrial DC/DC converter designs.
Technical Context
This MOSFET employs a trench-based silicon process optimized for low gate charge × RDS(on) figure-of-merit (FOM), enabling efficient operation above 500 kHz in hard-switched topologies. Its logic-level gate threshold (1.2–2.0 V) ensures full enhancement with 3.3 V or 5 V drive, eliminating need for gate boosters in low-voltage control stages.
The integrated body diode exhibits low Qrr (≤10 nC) and fast reverse recovery, supporting synchronous rectification without external Schottky replacement. Thermal design leverages the TO252's exposed drain pad for direct PCB copper conduction, achieving 50 K/W junction-to-ambient with 6 cm² cooling area.
Key Specifications

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 |
|---|---|---|---|
| IPB052N03L G | RDS(on) = 5.2 mΩ @ 10 V; TO-263 package; higher Qg (22 nC) | Larger footprint; better conduction loss but slower switching than IPDH6N03LAG | Prefer when thermal mass > switching speed; avoid in >1 MHz designs due to gate charge penalty |
| IRLHS6342TRPBF | RDS(on) = 7.5 mΩ @ 4.5 V; PQFN 3.3×3.3 mm; RthJC = 3.0 K/W | Smaller footprint and lower profile; higher thermal resistance limits power density | Choose for space-constrained layouts where 50 A peak is intermittent, not continuous |
Compared with IPB052N03LG and IRLHS6342TRPBF, IPDH6N03LAG offers the optimal balance of low RDS(on), moderate gate charge, and proven thermal performance in TO252 - making it preferred for high-reliability, high-current, medium-frequency POL applications.

FAQ
What is the maximum continuous drain current at 100 °C case temperature?
The datasheet specifies 50 A continuous drain current at both TC = 25 °C and TC = 100 °C. This reflects bondwire-limited current handling rather than thermal limitation; actual usable current at elevated case temperatures depends on PCB layout and cooling area, with derating beginning above 100 °C per the safe operating area curve.
Is IPDH6N03LAG suitable for synchronous rectification in a 1 MHz buck converter?
Yes - its 14–19 nC total gate charge, ≤10 nC reverse recovery charge, and fast switching times (tr = 5.4–8 ns, tf = 4.2–6.3 ns) support reliable synchronous rectification at 1 MHz. The low Qrr minimizes turn-on loss and EMI, provided gate drive strength exceeds 2 A peak and layout minimizes parasitic inductance.
Does this MOSFET require a gate resistor for stability in high-speed switching?
A small gate resistor (1–5 Ω) is recommended to dampen ringing caused by gate loop inductance and Miller capacitance. The device's 1.3 Ω intrinsic gate resistance helps limit dv/dt, but external series resistance improves EMI performance and prevents overshoot when driven by high-slew-rate controllers like the IR352xx or MP296x families.
How does the PG-TO252-3-11 package differ from PG-TO252-3-23 in IPFH6N03LAG?
PG-TO252-3-11 has a standard leadframe configuration with full-width drain tab and standard pin pitch; PG-TO252-3-23 features a modified leadframe with enhanced thermal pad geometry and tighter internal wirebonding - resulting in marginally lower RthJC (2.0 vs. 2.1 K/W) and improved pulse current capability, though both share identical pinout and footprint compatibility.
