Product details

Overview

IPB14N03LA G from Infineon Technologies is an N-channel logic-level OptiMOS®2 power MOSFET in PG-TO263-3-2 package, rated for 25 V V_DS, 30 A continuous drain current at T_C = 25 °C, and 13.6 mΩ R_DS(on) (max) at V_GS = 10 V - optimized for high-frequency DC/DC converters in server VRMs and POL modules.

For engineers reviewing the IPB14N03LA G datasheet, IPB14N03LA G pinout, IPB14N03LA G application, or IPB14N03LA G equivalent, key selection criteria include its 3.2 K/W junction-to-case thermal resistance, dv/dt rating of 6 kV/µs, gate charge total of 6.3–8.3 nC, and 175 °C maximum operating temperature for robust industrial and computing power stages.

Technical Context

This MOSFET employs trench-based silicon technology with optimized cell pitch and reduced gate-drain charge (Q_gd = 1.8–2.7 nC) to achieve low gate charge × R_DS(on) figure-of-merit (FOM), enabling efficient switching in synchronous buck topologies above 300 kHz. Its logic-level gate threshold (V_GS(th) = 1.2–2.0 V) ensures full enhancement with 3.3 V or 5 V gate drivers.

The device integrates a robust body diode with Q_rr ≤ 10 nC and V_SD ≤ 1.2 V at I_F = 30 A, supporting high-efficiency synchronous rectification and hard-switched flyback designs. Thermal design is enabled by its low R_thJC (3.2 K/W) and compatibility with standard FR4 PCBs featuring ≥6 cm² copper area on drain pad.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	25 V - supports 12 V input rails with margin for transient spikes in point-of-load converters
R_DS(on) max	13.6 mΩ at V_GS = 10 V - enables <1 W conduction loss at 30 A in compact thermal layouts
Q_g total	6.3–8.3 nC - allows fast switching with low gate drive power in high-frequency operation
R_thJC	3.2 K/W - permits direct heatsink mounting for >40 W power dissipation without derating
T_j max	175 °C - sustains reliable operation under sustained overload or ambient temperatures up to 125 °C
dv/dt rating	6 kV/µs - prevents spurious turn-on in noisy high-di/dt environments like motor drives
I_D pulsed	210 A - handles short-circuit events in protection-enabled SMPS designs

Pinout & Package

IPB14N03LA G uses the PG-TO263-3-2 (D²PAK) surface-mount package with exposed drain 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 electrode	Logic-level compatible; requires ≤10 V drive for full enhancement; low C_iss (784–1043 pF) minimizes driver loading
Pin 2 (Drain)	Main current path output	Exposed copper tab - must be soldered to ≥6 cm² PCB copper pour for thermal management and low-inductance return path
Pin 3 (Source)	Reference node for gate drive	Provides Kelvin sense path for accurate gate voltage control; ties to power ground in synchronous buck high-side configuration

Key Features

Feature	Design Value
Optimized FOM (Q_g × R_DS(on))	Enables >95% efficiency in 500 kHz–1 MHz DC/DC converters with minimal gate drive loss
175 °C rated junction temperature	Eliminates need for thermal derating in sealed enclosures or high-ambient industrial systems
dv/dt ruggedness	Withstands 6 kV/µs without false triggering - critical for half-bridge and LLC resonant converter reliability
Low Q_rr body diode	10 nC reverse recovery charge reduces switching losses and EMI in synchronous rectifier applications
Pb-free & RoHS compliant	Meets global environmental compliance requirements without performance trade-offs

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	R_DS(on) = 12 mΩ @ 10 V, but higher Q_g (18 nC) and no dv/dt rating specified	Lacks documented dv/dt ruggedness and 175 °C rating - unsuitable for high-noise or high-temp environments	Prefer IPB14N03LA G where switching speed, thermal headroom, or noise immunity are critical
STL100N3LLH6	Same V_DS (30 V), lower R_DS(on) (9.5 mΩ), but Q_gd = 4.2 nC - higher switching loss	Better conduction loss but inferior FOM; less suitable for >500 kHz operation	Choose IPB14N03LA G when optimizing for combined conduction + switching loss in high-frequency designs

Compared with IRL3803PBF and STL100N3LLH6, IPB14N03LA G delivers superior dv/dt immunity, tighter thermal resistance control, and balanced FOM - making it optimal for high-reliability, high-frequency DC/DC where gate drive efficiency and ruggedness are prioritized over absolute lowest R_DS(on).

FAQ

Is IPB14N03LA G qualified for automotive applications?

No - while it operates up to 175 °C and meets JEDEC standards for target applications, IPB14N03LA G is not AEC-Q101 qualified. It is intended for industrial, computing, and telecom power systems. For automotive use, consider Infineon's AEC-Q101-qualified OptiMOS™ 5 or 6 series variants with identical voltage/current ratings.

What is the recommended PCB layout for thermal performance?

Mount the device on a vertical FR4 PCB with ≥6 cm² (40 mm × 40 mm) single-layer 70 µm copper area connected to the drain tab. Use multiple thermal vias under the tab to inner ground planes. Keep gate traces short and low-inductance; separate power and signal grounds to minimize noise coupling into the gate loop.

Does IPB14N03LA G support synchronous rectification in flyback converters?

Yes - its low Q_rr (≤10 nC) and V_SD ≤ 1.2 V at 30 A make it suitable for secondary-side synchronous rectification in discontinuous conduction mode (DCM) flyback converters up to 150 kHz. Ensure gate drive timing avoids shoot-through during diode conduction phase.

Can IPB14N03LA G replace older OptiMOS®1 devices in existing designs?

Yes - it is a direct drop-in replacement for IPB12N03LA G and similar OptiMOS®1 parts in PG-TO263-3-2 package, offering improved R_DS(on), lower Q_g, and enhanced dv/dt rating. No layout changes are required, but verify gate drive strength due to slightly higher C_iss (784–1043 pF vs. ~650 pF).
