Product details

Overview

IPI50N12S3L15AKSA1 from Infineon Technologies is an AEC-Q101 qualified N-channel enhancement-mode power MOSFET in PG-TO262-3-1 package, rated for 120 V V_DS, 50 A continuous drain current at T_C = 25 °C, and 15.4 mΩ max R_DS(on) at V_GS = 10 V. It operates up to 175 °C junction temperature, supports 100% single-pulse avalanche testing (E_AS = 330 mJ), and is used in automotive DC-DC converters and motor control inverters.

For engineers reviewing the IPI50N12S3L15AKSA1 datasheet, IPI50N12S3L15AKSA1 pinout, IPI50N12S3L15AKSA1 application, or IPI50N12S3L15AKSA1 equivalent, key selection criteria include its 120 V breakdown voltage, low 15.4 mΩ on-resistance at 10 V gate drive, AEC-Q101 qualification, TO-262 thermal performance (R_thJC = 1.5 K/W), and integrated body diode with 80 ns t_rr.

Technical Context

This OptiMOS™-T device uses trench-gate superjunction technology optimized for high-efficiency switching in 12 V–48 V automotive systems. Its gate threshold voltage (1.2–2.4 V) enables robust 3.3 V/5 V logic-level compatibility while maintaining noise immunity, and its low Q_gd/Q_g ratio (8–12 nC / 44–57 nC) supports fast, controllable turn-off in hard-switched topologies.

The MOSFET integrates a co-packaged freewheeling diode with 0.6–1.2 V forward voltage at 50 A and 185 nC reverse recovery charge, enabling synchronous rectification and bidirectional energy handling in H-bridge and buck-boost configurations without external diode addition.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	120 V - Withstands 120 V drain-source blocking voltage, suitable for 48 V automotive battery systems with margin.
R_DS(on) max	15.4 mΩ @ V_GS = 10 V - Enables <1.5 W conduction loss at 50 A, critical for thermally constrained engine bay modules.
I_D continuous	50 A @ T_C = 25 °C - Supports high-current motor phase legs and starter solenoid drivers.
E_AS	330 mJ - Guarantees ruggedness against inductive switching transients in automotive load dumps and relay coil de-energization.
t_rr	80 ns - Limits diode reverse recovery losses during commutation, reducing EMI and gate driver stress.
Q_g	44–57 nC - Determines gate drive power requirement; compatible with standard 1–2 A peak gate drivers.

Pinout & Package

Package: PG-TO262-3-1 (leadless variant of TO-262, surface-mount compatible with through-hole footprint). Thermal pad on drain terminal enables direct PCB copper pour attachment for enhanced heat dissipation.

Pin 1 (Drain)	Main current path output	Connected to large copper area on PCB; primary thermal path to heatsink via case.
Pin 2 (Gate)	Control input	High-impedance MOS gate requiring low-inductance routing and RC snubber for EMI suppression.
Pin 3 (Source)	Reference node	Return path for load current and gate drive loop; must be low-inductance connection to minimize shoot-through risk.

Key Features

Feature	Design Value
AEC-Q101 qualification	Validated for automotive powertrain and chassis applications per stress test requirements including HTGB, HTRB, and temperature cycling.
100% avalanche tested	Each unit undergoes single-pulse avalanche stress at I_D = 25 A, ensuring consistent ruggedness without screening fallout.
MSL1 rating	Compatible with standard 260 °C lead-free reflow profiles without popcorn or delamination risk.
Green product (RoHS)	Lead-free, halogen-free construction compliant with EU Directive 2011/65/EU and automotive ELV requirements.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
IPP50N12S3L-15	Same die, PG-TO220-3-1 package; higher R_thJA (62 K/W vs. 40 K/W on PCB) and no exposed thermal pad.	Better suited for prototyping or low-volume manual assembly where through-hole mounting is preferred.	Select when board space permits larger footprint and thermal design relies on heatsink clamping rather than PCB copper area.
IPB50N12S3L-15	Same die, PG-TO263-3-2 package; identical R_thJC but different pin layout and marking (3N12L15).	Optimized for automated SMT placement on double-sided boards with bottom-side thermal relief.	Select when using reflow-only processes and requiring maximum thermal performance with minimal board real estate.

Compared with IPP50N12S3L-15 and IPB50N12S3L-15, IPI50N12S3L15AKSA1 offers the best compromise between TO-262 mechanical robustness and SMT-compatible thermal performance-its PG-TO262-3-1 footprint supports both wave soldering and reflow while delivering 1.5 K/W junction-to-case resistance.

FAQ

Is IPI50N12S3L15AKSA1 pin-compatible with IPP50N12S3L-15?

No. IPI50N12S3L15AKSA1 uses PG-TO262-3-1 packaging with gull-wing leads, while IPP50N12S3L-15 uses PG-TO220-3-1 with through-hole pins. Footprint, thermal pad layout, and soldering method differ; mechanical adaptation is required for substitution.

What is the maximum gate-source voltage rating?

The absolute maximum gate-source voltage is ±20 V. Operation beyond ±16 V risks permanent oxide damage. For reliable 10 V gate drive, use a dedicated gate driver IC with rail-to-rail output and overvoltage clamping, such as the 1EDN7512B.

Does this MOSFET require a gate resistor for stability?

Yes. A 5–10 Ω series gate resistor is recommended to dampen parasitic oscillation caused by gate-drain capacitance and PCB trace inductance. Values below 3 Ω increase risk of ringing; above 22 Ω slows switching and raises dynamic losses unnecessarily.

Can it replace older OptiMOS™-2 generation parts?

Yes, with validation. IPI50N12S3L15AKSA1 offers lower R_DS(on), improved E_AS, and tighter V_GS(th) distribution versus OptiMOS™-2 equivalents like IPP50N12S2L-15. Layout changes may be needed due to different thermal pad geometry and gate drive timing.
