Product details

Overview

IPP50N12S3L15AKSA1 from Infineon Technologies is an AEC-Q101 qualified N-channel enhancement-mode power MOSFET in PG-TO220-3-1 package, rated for 120 V V_DS, 50 A continuous drain current at T_C = 25 °C, and 15.4 mΩ R_DS(on) max at V_GS = 10 V. It operates up to 175 °C junction temperature and is 100% avalanche tested for automotive motor control and DC-DC converter primary-side switching.

For engineers reviewing the IPP50N12S3L15AKSA1 datasheet, IPP50N12S3L15AKSA1 pinout, IPP50N12S3L15AKSA1 application, or IPP50N12S3L15AKSA1 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-220 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 low conduction and switching losses in 12 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 44–57 nC total gate charge supports efficient PWM operation at frequencies up to several hundred kHz.

The MOSFET integrates a fast-recovery body diode (t_rr = 80 ns, Q_rr = 185 nC) with soft recovery characteristics, reducing EMI in hard-switched topologies. Thermal design is enabled by its 1.5 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	120 V - Supports 12 V automotive battery systems with ≥2× overvoltage margin against load dump transients
R_DS(on) max	15.4 mΩ @ V_GS = 10 V - Enables ≤7.7 W conduction loss at 50 A, critical for thermally constrained engine bay layouts
I_D cont	50 A @ T_C = 25 °C - Rated for high-current motor phase legs and starter solenoid drivers
E_AS	330 mJ - Guarantees single-pulse avalanche ruggedness under inductive turn-off stress without external snubbers
t_rr	80 ns - Limits reverse recovery switching loss and dv/dt-induced shoot-through risk in half-bridge configurations
Q_g	44–57 nC - Determines gate driver power requirement and switching speed trade-off in 20–200 kHz SMPS designs
T_j max	+175 °C - Allows operation in under-hood environments without derating below 150 °C ambient

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
IPB50N12S3L15AKSA1	PG-TO263-3-2 package; lower R_thJA (40 K/W on 6 cm² PCB) vs. TO-220's 62 K/W	Better suited for surface-mount, space-constrained PCBs with limited heatsink area	Select when board-level thermal management favors D²PAK over through-hole mounting
IPI50N12S3L15AKSA1	PG-TO262-3-1 package; identical die but non-insulated tab; R_thJC = 1.5 K/W same as IPP version	Requires isolated mounting hardware if heatsink is grounded; lower assembly cost in chassis-grounded systems	Select when mechanical mounting allows direct tab-to-chassis contact and isolation is not required

Compared with IPB50N12S3L15AKSA1 and IPI50N12S3L15AKSA1, IPP50N12S3L15AKSA1 offers electrical equivalence and identical silicon performance but provides insulated mounting and through-hole reliability preferred in high-vibration engine bay environments.

FAQ

What is the maximum allowable gate-source voltage for IPP50N12S3L15AKSA1?

The absolute maximum V_GS is ±20 V. Operation beyond this risks irreversible gate oxide damage. Recommended gate drive is 10 V for full R_DS(on) specification compliance, though 4.5 V is sufficient for logic-level compatibility with 16.1 mΩ typical on-resistance.

Does IPP50N12S3L15AKSA1 require a gate resistor, and what value is recommended?

Yes-a gate resistor is required to control dV/dt and prevent oscillation. For 50 A switching at 100 kHz, a 3.5 Ω resistor is validated in the datasheet to achieve optimal t_r/t_f balance. Lower values increase EMI risk; higher values raise switching losses.

Can IPP50N12S3L15AKSA1 be used in parallel configurations?

Yes-its positive temperature coefficient for R_DS(on) (increasing ~0.5%/°C) enables inherent current sharing. Layout symmetry, matched gate drive paths, and individual source resistors are required to ensure balanced dynamic current distribution across paralleled devices.

Is thermal pad soldering required for the TO-220 tab, and what solder mask clearance is advised?

Yes-the drain-connected metal tab must be soldered to a large copper pour for thermal integrity. A minimum 10 mm × 10 mm exposed copper area with 2 oz copper weight is specified. Solder mask should be fully removed from the tab footprint; no solder mask dams are permitted under the tab.
