Product details

Overview

IPB240N04S41R0ATMA1 from Infineon Technologies is an AEC-Q101 qualified N-channel enhancement-mode MOSFET in PG-TO263-7-3 package, rated for 40 V V_DS, 1.0 mΩ R_DS(on) at 100 A/10 V, and 240 A continuous drain current at T_C = 25 °C. It features 100% single-pulse avalanche testing (750 mJ), 175 °C max operating temperature, and ultra-low gate charge (Q_g = 170–221 nC), targeting high-efficiency 12 V automotive power stages.

For engineers reviewing the IPB240N04S41R0ATMA1 datasheet, IPB240N04S41R0ATMA1 pinout, IPB240N04S41R0ATMA1 application, or IPB240N04S41R0ATMA1 equivalent, key selection criteria include R_DS(on) stability over temperature, avalanche ruggedness under inductive switching, thermal resistance (R_thJC = 0.65 K/W), and gate drive compatibility with 5.5 V plateau voltage.

Technical Context

This OptiMOS™-T2 device uses trench-gate superjunction technology optimized for low conduction and switching losses in 12 V automotive systems. Its 0.85–1.00 mΩ R_DS(on) range at 100 A/10 V and 5.5 V gate plateau enable robust turn-on control with standard 5 V logic drivers while maintaining fast switching (t_r = 28 ns, t_f = 47 ns).

The MOSFET integrates a co-packaged body diode with 0.9–1.3 V forward voltage at 100 A and 80 ns reverse recovery time, supporting synchronous rectification and freewheeling in DC-DC converters and motor drives. Thermal design is enabled by its 0.65 K/W junction-to-case resistance and MSL1 reflow rating up to 260 °C.

Key Specifications

t_r/t_f	28 ns / 47 ns - Fast edge rates minimize switching transition losses in hard-switched topologies

Pinout & Package

IPB240N04S41R0ATMA1 uses the PG-TO263-7-3 surface-mount package with exposed drain pad (pins 1–3 and 7 are drain), single gate (pin 4), and source terminals (pins 5–6). The package supports high-current PCB routing and efficient thermal transfer via bottom-side copper area.

Pin/Terminal	Circuit Role	Design Meaning

4	Gate (G)	Control input requiring <221 nC charge; sensitive to ESD and ringing
5, 6	Source (S)	Power return path; referenced for gate drive and current sensing

Key Features

Feature	Design Value

Equivalent & Alternatives

The following parts are listed as comparable options for similar 40 V automotive power MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STL220N4LF8AG	R_DS(on) = 0.95 mΩ, Q_g = 205 nC, R_thJC = 0.70 K/W, same PG-TO263-7-3	Slightly higher conduction loss and thermal resistance; identical AEC-Q101 and avalanche rating	Preferred where Infineon supply continuity is constrained but identical footprint and drive requirements apply
IRL40B216TRPBF	R_DS(on) = 1.15 mΩ, Q_g = 192 nC, R_thJC = 0.60 K/W, TO-263AB-7	Higher R_DS(on) offsets lower thermal resistance; no 100% avalanche test documentation	Used when marginally higher on-resistance is acceptable and tighter thermal budget allows smaller heatsink

Compared with STL220N4LF8AG and IRL40B216TRPBF, IPB240N04S41R0ATMA1 delivers the lowest R_DS(on) and highest verified avalanche energy, making it optimal for safety-critical 12 V power stages where conduction loss and fault robustness are prioritized over minor gate charge differences.

FAQ

What is the maximum allowable gate-source voltage for IPB240N04S41R0ATMA1?

The absolute maximum V_GS is ±20 V, with recommended operating range of –10 V to +10 V. Exceeding ±20 V risks permanent gate oxide damage. Gate drive circuits must include clamping (e.g., Zener diodes) to prevent overshoot during fast switching transitions, especially in high-dV/dt environments like motor drives.

Does IPB240N04S41R0ATMA1 require a gate resistor, and what value is recommended?

Yes-a gate resistor is required to dampen ringing and control dV/dt. For typical 12 V automotive applications with 5 V gate drivers, a 3.5 Ω resistor is validated in the datasheet for 240 A switching. Values between 2.2 Ω and 5.6 Ω balance switching speed, EMI, and driver stress; lower values increase peak gate current and may exceed driver capability.

Can IPB240N04S41R0ATMA1 be used in parallel configurations?

Yes-its positive temperature coefficient of R_DS(on) (increasing with junction temperature) enables stable current sharing. Parallel use requires matched layout (symmetrical trace lengths, shared heatsink), identical gate drive paths, and individual gate resistors. Derating to ≤200 A per device is advised for long-term reliability under thermal cycling.

Is the body diode suitable for continuous freewheeling in synchronous rectification?

Yes-the integrated body diode is rated for 240 A continuous forward current and 960 A pulsed current, with V_SD = 0.9–1.3 V at 100 A and t_rr = 80 ns. It supports synchronous rectification in buck converters, but external Schottky diodes may be preferred where ultra-low forward drop (<0.5 V) is mandatory at light loads.
