Product details

Overview

IPP04N03LA from Infineon Technologies is a logic-level N-channel enhancement-mode MOSFET optimized for high-frequency DC/DC converters, featuring 25 V V_DS, 4.2 mΩ R_DS(on) at V_GS = 10 V and I_D = 55 A, 175 °C maximum junction temperature, and dv/dt ruggedness rated to 6 kV/μs - deployed in synchronous buck converters for server VRMs and telecom power supplies.

For engineers reviewing the IPP04N03LA datasheet, IPP04N03LA pinout, IPP04N03LA application, or IPP04N03LA equivalent, key selection criteria include gate charge (Q_g = 24–32 nC), thermal resistance (R_thJC = 1.4 K/W), reverse diode forward voltage (V_SD = 0.96–1.2 V at 80 A), and SOA robustness under pulsed drain current up to 385 A.

Technical Context

This OptiMOS®2 device uses trench-gate superjunction technology to achieve low R_DS(on) × Q_g figure-of-merit (FOM) for efficient switching in hard-switched topologies. Its gate threshold voltage (V_GS(th) = 1.2–2.0 V) enables direct drive from 3.3 V or 5 V logic controllers without level-shifting.

The integrated body diode supports synchronous rectification with low Q_rr (≤15 nC) and fast recovery, while dv/dt immunity ensures reliable operation during high-slew-rate transients in compact, high-density power stages.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	25 V - defines maximum blocking voltage in low-voltage synchronous buck high-side or low-side switch applications
R_DS(on) max	4.2 mΩ @ V_GS = 10 V, I_D = 55 A - enables <1 W conduction loss at 80 A continuous drain current
Q_g	24–32 nC - determines gate driver power requirement and switching speed in 300–1000 kHz converters
R_thJC	1.4 K/W - allows 76 W power dissipation at ΔT = 107 K with case temperature held at 25 °C
I_D continuous	80 A @ T_C = 25 °C - supported by TO-220 package with copper tab and solderable drain pad
V_GS(th)	1.2–2.0 V - ensures full enhancement with standard logic-level gate drivers (e.g., TI UCC2753x, ON Semi NCP3420)
dv/dt rating	6 kV/μs - prevents false turn-on during high di/dt commutation in multiphase VRMs

Pinout & Package

IPP04N03LA is housed in PG-TO220-3 package: insulated plastic case with three leads - Drain (tab), Source (pin 1), Gate (pin 2). The metal tab is electrically connected to Drain and serves as primary heat path.

Pin/Terminal	Circuit Role	Design Meaning
Drain (Tab)	Main current-carrying terminal, high-side switch node	Electrically tied to heatsink; requires isolation washer if heatsink is grounded
Source (Pin 1)	Reference node for gate drive and current sensing	Low-inductance connection essential for stable gate control and accurate R_DS(on)-based current monitoring
Gate (Pin 2)	Control input for channel modulation	High-impedance node; requires low-impedance gate driver with ≤2.7 Ω series resistance to damp ringing

Key Features

Feature	Design Value
Logic-level gate drive compatibility	Operates fully enhanced at V_GS ≥ 4.5 V - eliminates need for bootstrap or charge-pump gate drivers in 5 V systems
Low R_DS(on) × Q_g FOM	~100 mΩ·nC - balances conduction and switching losses for peak efficiency at 500 kHz in 12 V input VRMs
175 °C rated junction temperature	Enables derated operation in sealed enclosures or high-ambient industrial power modules without forced air
dv/dt ruggedness	6 kV/μs - sustains reliable operation during rapid voltage transients in multi-phase interleaved converters
Integrated robust body diode	V_SD = 0.96 V @ 80 A, Q_rr ≤ 15 nC - reduces reverse recovery loss and EMI in synchronous rectification

Equivalent & Alternatives

The following parts are listed as comparable options for similar logic-level N-channel MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
IRL3803PbF	R_DS(on) = 6.0 mΩ @ 10 V; Q_g = 33 nC; TO-220AB package	Higher conduction loss and slower switching - suitable only for <300 kHz designs with relaxed efficiency targets	Select when legacy design reuse or second-source qualification is required over optimal FOM
STL220N3LLH6	R_DS(on) = 3.2 mΩ @ 10 V; Q_g = 42 nC; PowerFLAT 5x6 package	Lower R_DS(on) but higher Q_g and surface-mount only - demands PCB layout revision and thermal via optimization	Select for new designs prioritizing conduction loss reduction where board space permits SMT integration

Compared with IRL3803PbF, IPP04N03LA delivers 30% lower R_DS(on) and 25% lower Q_g, improving both conduction and switching efficiency; versus STL220N3LLH6, it trades 24% higher R_DS(on) for through-hole assembly compatibility and proven thermal performance in legacy TO-220 heatsink footprints.

FAQ

Is IPP04N03LA suitable for synchronous rectification in LLC resonant converters?

Yes. Its low Q_rr (≤15 nC), soft-recovery body diode, and 6 kV/μs dv/dt rating make it suitable for secondary-side synchronous rectification in LLC converters operating up to 1 MHz. Measured V_SD of 0.96 V at 80 A ensures minimal forward conduction loss during freewheeling intervals.

What is the maximum continuous drain current at 100 °C case temperature?

The datasheet specifies I_D = 80 A at both T_C = 25 °C and T_C = 100 °C. This reflects bondwire-limited current capacity rather than thermal limitation - the device maintains full 80 A rating up to 100 °C case temperature due to its 1.4 K/W R_thJC and robust internal interconnect.

Does IPP04N03LA require a gate resistor for stability in 500 kHz operation?

Yes. A 2.2–2.7 Ω non-inductive gate resistor is recommended to damp high-frequency ringing caused by gate-drain capacitance (Crss = 175–263 pF) and PCB trace inductance. This value aligns with Infineon's reference design guidelines for OptiMOS®2 devices in hard-switched buck converters.

Can IPP04N03LA be used in parallel configurations for higher current handling?

Yes. Its positive temperature coefficient of R_DS(on) (increases with junction temperature) enables inherent current sharing when paralleled. Layout must ensure matched gate drive paths and symmetrical source inductance; typical designs use 2–4 devices per phase with individual 1 Ω gate resistors and Kelvin source connections.
