Product details

Overview

IPP042N03LGHKSA1 from Infineon Technologies is a 30 V, 100 A, N-channel enhancement-mode power MOSFET in TO-220FP package, featuring 4.2 mΩ R_DS(on) at V_GS = 10 V, optimized for high-efficiency DC-DC converters and motor control in automotive body electronics.

For engineers reviewing the IPP042N03LGHKSA1 datasheet, IPP042N03LGHKSA1 pinout, IPP042N03LGHKSA1 application, or IPP042N03LGHKSA1 equivalent, key selection criteria include low conduction loss at 12 V gate drive, avalanche ruggedness (E_AS = 275 mJ), and AEC-Q101 qualification for under-hood use.

Technical Context

This MOSFET employs Infineon's OptiMOS™ 3 technology, delivering reduced switching losses via low Q_g (38 nC) and Q_gd (12 nC), enabling efficient operation in synchronous rectification and high-frequency PWM circuits up to 500 kHz.

Its integrated body diode exhibits t_rr = 42 ns and Q_rr = 49 nC, supporting fast commutation in half-bridge topologies without external Schottky clamping, while the 100% UIS-tested structure ensures robustness against inductive load transients.

Key Specifications

Parameter	Value and Actual Design Meaning
R_DS(on) max @ V_GS = 10 V	4.2 mΩ - Enables ≤1.2 W conduction loss at 100 A continuous drain current in thermally constrained PCB layouts.
I_D continuous @ T_C = 25°C	100 A - Supports high-current loads such as electric power steering (EPS) H-bridge legs and HVAC blower drivers.
V_DS max	30 V - Rated for 12 V automotive systems with transient overvoltage tolerance up to ISO 7637-2 Pulse 5a (75 V).
Q_g typ	38 nC - Reduces gate driver power demand and enables use of low-cost SOT-23 gate drivers like 1EDN7512B.
E_AS @ I_D = 50 A	275 mJ - Guarantees single-pulse avalanche capability during inductive turn-off in motor phase-legs without derating.
t_r/t_f	12 ns / 10 ns - Allows clean switching edges in 200–500 kHz SMPS designs, minimizing EMI filter size.

Pinout & Package

Delivered in TO-220FP (Full-Pak) package with isolated flange, enabling direct heatsink mounting without insulating pads. Drain connected to flange; source and gate on leads.

Pin/Terminal	Circuit Role	Design Meaning
Drain (Flange)	Main current path output terminal	Electrically tied to heatsink; requires thermal interface but no electrical isolation pad in most chassis-grounded applications.
Source	Reference node for gate drive and current sensing	Provides low-inductance return path for high di/dt currents; used for shunt-based current feedback in motor control.
Gate	Control electrode for channel conduction	Accepts standard 10 V logic-level drive; Miller plateau voltage ~3.5 V ensures noise immunity in noisy automotive environments.

Key Features

Feature	Design Value
AEC-Q101 qualified	Validated for automotive temperature range (−40 °C to 175 °C junction), including HTOL, TC, and UHAST stress testing.
Low R_DS(on) × Q_g figure-of-merit	159 mΩ·nC - Optimized trade-off between conduction and switching loss for 12 V battery-fed systems.
100% UIS tested	No screening failure across production lots - eliminates field failures due to unclamped inductive switching events.
Enhanced dv/dt ruggedness	≥50 V/ns - Prevents spurious turn-on during fast voltage transients in half-bridge configurations.

Applications

12 V DC-DC Buck Converter

Use Scenario: Driving high-current solenoids for door locks and trunk latches in BCMs.

IC Role / Device Role: Low-side switch controlling 30–60 A peak inductive loads.

Use Value: 4.2 mΩ R_DS(on) limits self-heating to <15 K rise at 50 A, eliminating need for forced air cooling.

Use Scenario: High-efficiency 12 V → 5 V/3.3 V step-down converter for infotainment domain controllers.

IC Role / Device Role: Synchronous rectifier in 300 kHz buck stage.

Use Value: Low Q_rr (49 nC) and fast t_rr (42 ns) minimize reverse recovery loss and cross-conduction risk.

Electric Power Steering (EPS) Motor Phase Leg

Automotive HVAC Blower Driver

Use Scenario: Half-bridge leg in 3-phase EPS inverter driving 15 kW brushless motor.

IC Role / Device Role: High-side and low-side switching element with integrated avalanche capability.

Use Value: 275 mJ E_AS withstands worst-case short-circuit energy during torque assist transients.

Use Scenario: PWM-controlled 12 V blower motor driver in climate control system.

Use Value: TO-220FP flange enables direct bolt-to-chassis thermal path, sustaining 100 A pulsed current without thermal shutdown.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STL220N3LLHAG	R_DS(on) = 3.8 mΩ @ 10 V, but Q_g = 49 nC - higher switching loss at >200 kHz.	Qualified to AEC-Q101 but lacks 100% UIS test documentation in public datasheet.	Preferable only when absolute minimum R_DS(on) dominates over switching frequency constraints.
ON Semiconductor NTMFS4C09NT1G	R_DS(on) = 4.5 mΩ @ 10 V, Q_g = 35 nC - slightly lower gate charge but higher conduction loss.	TO-220-3L (non-isolated flange); requires insulating pad for heatsink mounting.	Choose when gate drive efficiency is prioritized and thermal interface complexity must be minimized.

Compared with STL220N3LLHAG and NTMFS4C09NT1G, IPP042N03LGHKSA1 uniquely balances ultra-low R_DS(on), industry-leading UIS robustness, and isolated flange packaging-making it optimal for safety-critical, thermally dense automotive power stages where reliability trumps marginal R_DS(on) gains.

FAQ

What is the maximum junction temperature rating for IPP042N03LGHKSA1?

The absolute maximum junction temperature is 175 °C, validated per AEC-Q101 stress testing. Continuous operation at this temperature requires thermal design ensuring case temperature remains ≤110 °C under worst-case ambient and power dissipation conditions, as defined in the official Infineon datasheet Rev. 2.0 (2022).

Does IPP042N03LGHKSA1 support 5 V gate drive?

No - the device is not specified for full enhancement at 5 V. Its threshold voltage V_GS(th) ranges from 1.0 V to 2.5 V, but R_DS(on) is guaranteed only at V_GS = 10 V. At 5 V, typical R_DS(on) exceeds 12 mΩ, increasing conduction loss by >180% versus rated performance.

Is the TO-220FP flange electrically isolated from the source pin?

Yes - the TO-220FP package features an isolated flange internally connected to the drain. This allows direct mechanical attachment to a grounded heatsink without electrical shorting, provided the PCB layout maintains clearance between flange-mounting screws and source traces.

Can IPP042N03LGHKSA1 replace IPP045N03L in existing designs?

Yes, with minor validation - both share identical pinout, package, and V_DS rating, but IPP042N03LGHKSA1 offers 7% lower R_DS(on) (4.2 mΩ vs. 4.5 mΩ) and improved UIS rating (275 mJ vs. 250 mJ). Thermal and layout compatibility is maintained; no schematic or firmware changes required.
