Product details

Overview

IPI120N10S405AKSA1 from Infineon Technologies is a 100 V, 120 A N-channel enhancement-mode MOSFET in PG-TO262-3-1 package, qualified to AEC-Q101 for automotive use, with 5.0 mΩ max R_DS(on) at V_GS = 10 V and 100% single-pulse avalanche tested to 330 mJ. It operates up to 175 °C and supports high-current motor control and DC-DC converter primary-side switching.

For engineers reviewing the IPI120N10S405AKSA1 datasheet, IPI120N10S405AKSA1 pinout, IPI120N10S405AKSA1 application, or IPI120N10S405AKSA1 equivalent, key selection criteria include R_DS(on) stability over temperature, avalanche ruggedness, thermal resistance (R_thJC = 0.8 K/W), and AEC-Q101 qualification for under-hood power electronics.

Technical Context

This OptiMOS™-T2 device uses trench-gate superjunction technology to achieve low conduction loss and fast switching with C_iss = 6540 pF (max) and Q_g = 91 nC (max). Its gate threshold voltage (2.0–3.5 V) enables robust TTL/CMOS-level drive compatibility while maintaining noise immunity.

The integrated body diode exhibits V_SD = 1.3 V (max) at 100 A and t_rr = 65 ns (max), supporting synchronous rectification and freewheeling in hard-switched topologies. Thermal design is enabled by its 0.8 K/W junction-to-case resistance and MSL1 rating for lead-free reflow up to 260 °C.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	100 V - Supports 48 V and 60 V nominal bus systems with 20 % derating margin.
R_DS(on) max	5.0 mΩ at V_GS = 10 V, T_j = 25 °C - Enables <1.2 W conduction loss at 100 A DC.
I_D continuous	120 A at T_C = 25 °C - Requires ≥6 cm² copper area on FR4 PCB for thermal management.
E_AS	330 mJ - Withstands single-pulse inductive energy without failure in motor phase-legs.
R_thJC	0.8 K/W - Allows direct heatsink mounting with minimal thermal interface resistance.
Avalanche rated	100 % production-tested - Eliminates need for external snubbers in flyback or buck-boost converters.
Q_g total	91 nC - Determines gate driver current requirement (~1.8 A peak for 50 ns rise time).

Pinout & Package

PG-TO262-3-1 (3-pin, straight leads, isolated tab), thermally optimized for vertical PCB mounting with drain-connected tab. Pin 1 = Gate, Pin 2 = Drain (tab), Pin 3 = Source.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Gate)	Control terminal	Receives 10 V logic-level signal; requires ≤3.5 Ω series gate resistor to limit dV/dt-induced oscillation.
Pin 2 (Drain)	High-side power node	Internally connected to metal tab; must be soldered to ≥6 cm² copper pour for thermal conduction.
Pin 3 (Source)	Reference return path	Serves as local ground reference for gate drive; layout must minimize inductance to prevent shoot-through.

Key Features

Feature	Design Value
AEC-Q101 qualified	Validated for automotive powertrain and chassis applications per stress test requirements.
175 °C operating temperature	Enables placement near heat sources (e.g., engine bay DC-DC modules) without derating.
MSL1 reflow rating	Withstands industry-standard lead-free reflow profiles without delamination or parameter shift.
Green Product (RoHS)	Complies with EU Directive 2011/65/EU; no lead, mercury, cadmium, hexavalent chromium, PBB, or PBDE.
Integrated body diode	Rated for 120 A continuous forward current and 480 A pulsed, enabling bidirectional current handling.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
IPP120N10S4-05	Same die, PG-TO220-3-1 package; R_thJA = 62 K/W (vs. 40 K/W for SMD version); no isolated tab.	Better suited for prototyping or low-volume industrial supplies where heatsink mounting is via screw.	Select when mechanical mounting flexibility outweighs thermal performance needs.
IPB120N10S4-05	Same die, PG-TO263-3-2 surface-mount package; identical R_DS(on), but 0.1 mm lower profile and solder-reflow compatible.	Preferred for automated assembly in space-constrained automotive ECUs requiring reflow-only processes.	Select when board-level automation and height constraints dominate thermal design.

Compared with IPP120N10S4-05 and IPB120N10S4-05, IPI120N10S405AKSA1 offers optimal thermal resistance (R_thJC = 0.8 K/W) and mechanical robustness for high-reliability through-hole mounting in harsh environments-making it the preferred choice for production automotive power modules where long-term thermal cycling stability is critical.

FAQ

What is the maximum allowable gate-source voltage for IPI120N10S405AKSA1?

The absolute maximum gate-source voltage is ±20 V. Operation beyond this range risks permanent gate oxide damage. For reliable switching, keep V_GS between 4.9 V (gate plateau) and 10 V-exceeding 15 V provides no benefit and increases risk of parasitic turn-on during high-dV/dt events.

Does IPI120N10S405AKSA1 require a negative gate voltage for turn-off in high-noise environments?

No. Its gate threshold voltage (2.0–3.5 V) and low input capacitance (6540 pF max) provide sufficient noise margin with 0 V turn-off. Negative bias is unnecessary unless operating in extreme EMI environments (>30 V/ns dV/dt) where active pull-down is already implemented in the gate driver IC.

Can IPI120N10S405AKSA1 replace IPP120N10S4-05 in an existing TO-220 footprint?

No-it uses PG-TO262-3-1, which has different lead spacing and tab isolation. While both share identical electrical specs, mechanical incompatibility prevents drop-in replacement. A PCB redesign is required to accommodate the wider lead pitch and isolated drain tab of the TO262 package.

Is the body diode in IPI120N10S405AKSA1 suitable for synchronous rectification?

Yes-the body diode is fully rated for 120 A continuous forward current and exhibits V_SD = 1.3 V (max) at 100 A and t_rr = 65 ns (max), making it viable for synchronous rectification in non-isolated DC-DC stages where external Schottky diodes would otherwise be used.
