Product details

Overview

IPZ40N04S5L3R6ATMA1 from Infineon is an N-channel logic-level automotive power MOSFET in PG-TSDSON-8-33 package, rated for 40 V V_DS, 3.6 mΩ R_DS(on) at V_GS = 10 V and 20 A, with 87 A chip-limited continuous drain current and 175 °C maximum operating temperature. It serves as a high-efficiency main or auxiliary switch in 12 V automotive power distribution systems.

For engineers reviewing the IPZ40N04S5L3R6ATMA1 datasheet, IPZ40N04S5L3R6ATMA1 pinout, IPZ40N04S5L3R6ATMA1 application, or IPZ40N04S5L3R6ATMA1 equivalent, key selection criteria include its AEC-Q101 qualification, MSL1 reflow capability, 100% avalanche testing, and low gate charge (Q_g = 25.2–32.8 nC) enabling fast switching in battery management and motor control circuits.

Technical Context

This OptiMOS™-5 device uses trench-gate superjunction technology optimized for low R_DS(on) × Q_g figure-of-merit in 12 V automotive systems. Its logic-level gate threshold (V_GS(th) = 1.2–2.0 V) ensures full enhancement with standard microcontroller GPIOs.

It integrates a robust body diode with t_rr = 31.3 ns and Q_rr = 19.2 nC, supporting synchronous rectification and freewheeling in H-bridge motor drivers. Thermal design is supported by R_thJC = 2.6 K/W and operation up to 175 °C junction temperature.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STL220N4F7AG	R_DS(on) = 3.7 mΩ @ 10 V; Q_g = 34 nC; T_j max = 175 °C; same PG-TSDSON-8-33 package	Slightly higher gate charge increases driver complexity; identical thermal and voltage ratings	Preferred when ST ecosystem integration or dual-sourcing with ST reference designs is required.
ON Semiconductor NTMFS4C09NT1G	R_DS(on) = 3.8 mΩ @ 10 V; Q_g = 29 nC; T_j max = 175 °C; PG-TSDSON-8-33 package	Higher R_DS(on) increases conduction loss by ~5.5% at 50 A; lower Q_g than ST part but higher than Infineon	Selected where ON's automotive qualification documentation or long-term supply assurance aligns with program requirements.

Compared with STL220N4F7AG and NTMFS4C09NT1G, IPZ40N04S5L3R6ATMA1 delivers the lowest R_DS(on) and best R_DS(on) × Q_g trade-off, making it optimal for thermally constrained, high-efficiency 12 V automotive power stages where conduction loss dominates total loss budget.

FAQ

Is IPZ40N04S5L3R6ATMA1 pin-compatible with earlier OptiMOS™ generations?

No. IPZ40N04S5L3R6ATMA1 uses the PG-TSDSON-8-33 package with source-connected pins 1–3 and 5–7, differing from legacy SO-8 or TO-220 footprints. Layout redesign is required; no mechanical or electrical drop-in replacement exists within the OptiMOS™ family.

What is the maximum recommended PCB copper area for thermal performance?

For optimal R_thJA = 39.5 K/W, Infineon specifies a 2s2p FR4 PCB layout per JESD51-5/-7: minimum 100 mm² exposed drain pad copper connected to inner ground plane via ≥4 thermal vias (0.3 mm diameter, 0.8 mm pitch). Larger copper improves thermal margin but does not reduce R_thJC.

Does this MOSFET require external gate resistors in automotive PWM applications?

Yes. Although logic-level compatible, a series gate resistor (typically 2.2–10 Ω) is required to damp ringing, limit peak gate current, and control dV/dt during fast switching in noisy automotive environments. Values must be validated with actual gate driver IC output impedance and PCB parasitics.

Can IPZ40N04S5L3R6ATMA1 be used in 48 V mild-hybrid systems?

No. Its 40 V V_DS rating provides only 10 V margin above nominal 36 V battery voltage, insufficient for 48 V system transients (up to 58 V). Use 60 V or 75 V rated MOSFETs such as IPB180N04S4-03 for 48 V applications.
