Product details

Overview

IPP120N06S403AKSA1 from Infineon Technologies is a 60 V, 120 A N-channel enhancement-mode MOSFET in PG-TO220-3-1 package, AEC-Q101 qualified for automotive power switching, with R_DS(on) max 3.2 mΩ at V_GS = 10 V and 100% single-pulse avalanche tested to 392 mJ. It operates up to 175 °C and supports high-current DC-DC converters and motor control inverters.

For engineers reviewing the IPP120N06S403AKSA1 datasheet, IPP120N06S403AKSA1 pinout, IPP120N06S403AKSA1 application, or IPP120N06S403AKSA1 equivalent, key selection criteria include its 0.9 K/W junction-to-case thermal resistance, 120 A continuous drain rating at T_C = 100 °C, integrated body diode with 115 ns reverse recovery time, and RoHS-compliant green packaging.

Technical Context

This OptiMOS™-T2 device uses trench-gate superjunction technology optimized for low conduction and switching losses in 12 V–48 V automotive and industrial power stages. Its gate threshold voltage (2.0–4.0 V) enables robust TTL/CMOS-level drive compatibility while maintaining noise immunity.

The MOSFET features a fully characterized dynamic parameter set including C_iss = 13.15 nF, C_oss = 3.22 nF, and Q_g = 160 nC, supporting precise gate driver sizing for hard-switched topologies. Its 100% avalanche-tested ruggedness ensures reliability under inductive load turn-off stress.

Pin 1 (Source)	Source terminal of N-channel MOSFET	Reference node for gate drive and current sensing; connects to low-side return path
Pin 2 (Gate)	Control electrode	Accepts 0–10 V logic-level signal; requires 160 nC charge for full enhancement
Pin 3 (Drain)	Main current-carrying terminal	Internally bonded to metal tab; must be electrically isolated from heatsink unless system design permits common-drain configuration

Key Features

Feature	Design Value

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
IPP120N06N3G	R_DS(on) max = 2.7 mΩ; newer OptiMOS™-6 generation; lower Q_g (135 nC)	Better efficiency in high-frequency (>300 kHz) SMPS; higher cost	Select when optimizing for switching loss over conduction loss and budget allows upgrade
IRFB4115PBF	R_DS(on) max = 4.5 mΩ; non-AEC-Q101; TO-220AB package; no MSL1 rating	Suitable for industrial-only designs without automotive qualification or lead-free reflow needs	Choose only for cost-sensitive non-automotive applications where 1.3 mΩ higher R_DS(on) is acceptable

Compared with IPP120N06N3G, IPP120N06S403AKSA1 offers proven AEC-Q101 reliability and higher avalanche robustness but trades 25 nC more gate charge; versus IRFB4115PBF, it delivers 31% lower R_DS(on) and full automotive compliance at modest premium.

FAQ

What is the maximum allowable gate-source voltage for IPP120N06S403AKSA1?

The absolute maximum gate-source voltage is ±20 V. Operation beyond ±15 V risks permanent gate oxide damage. For reliable 10 V enhancement, a gate driver with tight regulation and transient clamping (e.g., TVS at gate) is recommended to suppress ringing-induced overshoot during fast switching.

Does IPP120N06S403AKSA1 require a negative gate voltage for turn-off in high-noise environments?

No. Its gate threshold voltage range (2.0–4.0 V) provides sufficient noise margin with 0 V turn-off. However, applying –5 V enhances immunity against dv/dt-induced false turn-on in high-side configurations with rapid drain voltage transients exceeding 50 V/ns.

Can IPP120N06S403AKSA1 be paralleled with identical units for higher current capacity?

Yes-its positive temperature coefficient of R_DS(on) (increases with junction temperature) enables inherently self-balancing current sharing. Use matched gate resistors (±5%) and symmetrical PCB layout with equal trace lengths to minimize dynamic imbalance during switching transitions.

Is the drain tab electrically isolated in the PG-TO220-3-1 package?

No-the drain is internally connected to the metal tab. Electrical isolation from the heatsink requires an insulating washer and thermal pad. Failure to isolate results in short-circuit if the heatsink is grounded or biased to another potential, violating safe operating area constraints.
