Product details

Overview

IPI50N10S3L16AKSA1 from Infineon Technologies is an AEC-Q101 qualified N-channel enhancement-mode power MOSFET in PG-TO262-3-1 package, rated for 100 V V_DS, 50 A continuous drain current at T_C = 25 °C, and 12.8–15.4 mΩ R_DS(on) at V_GS = 10 V. It delivers robust avalanche performance (330 mJ single-pulse E_AS) and operates up to 175 °C junction temperature-used in automotive DC-DC converters, motor control inverters, and high-reliability industrial power switches.

For engineers reviewing the IPI50N10S3L16AKSA1 datasheet, IPI50N10S3L16AKSA1 pinout, IPI50N10S3L16AKSA1 application, or IPI50N10S3L16AKSA1 equivalent, key selection criteria include its 100 V breakdown voltage, low gate charge (49–64 nC), 1.5 K/W R_thJC, integrated body diode with 80 ns t_rr, and AEC-Q101 qualification for automotive powertrain systems.

Technical Context

This OptiMOS™-T device uses trench-gate superjunction technology optimized for low conduction and switching losses in hard-switched topologies. Its gate threshold voltage (1.2–2.4 V) enables reliable turn-on with standard 5 V or 10 V logic-level drivers, while the 3.7 V gate plateau voltage supports stable Miller region control during commutation.

The MOSFET integrates a fast, soft-recovery body diode (t_rr = 80 ns, Q_rr = 185 nC) and is fully characterized for unclamped inductive switching (UIS) up to 330 mJ at T_j = 25 °C. Thermal resistance of 1.5 K/W (junction-to-case) ensures efficient heat transfer to heatsinks in TO-262 mounting configurations.

Key Specifications

FAQ

What is the maximum gate-source voltage rating for IPI50N10S3L16AKSA1?

The absolute maximum gate-source voltage is ±20 V. Operation beyond ±16 V risks permanent oxide damage. For reliable switching, gate drive should be limited to 10 V for full R_DS(on) optimization or 4.5 V for logic-level compatibility-both within safe operating area per datasheet Figure 8.

Does IPI50N10S3L16AKSA1 include an integrated body diode, and what are its key parameters?

Yes, it features a monolithic body diode with 50 A continuous forward current rating, 0.6–1.2 V forward voltage at 50 A and 25 °C, 80 ns reverse recovery time, and 185 nC reverse recovery charge. These values are measured under standardized conditions (V_R = 50 V, dI/dt = 100 A/µs) and support synchronous rectification in buck and flyback topologies.

Can IPI50N10S3L16AKSA1 be used in parallel configurations, and what layout considerations apply?

Yes, it supports paralleling due to positive temperature coefficient of R_DS(on). Critical layout practices include matched gate trace lengths, Kelvin source connections, symmetrical thermal paths to heatsink, and individual gate resistors (3.5 Ω typical) to prevent dynamic current imbalance. PCB copper area must be ≥6 cm² per device for optimal R_thJA.

Is IPI50N10S3L16AKSA1 compliant with RoHS and REACH regulations?

Yes, it is fully RoHS compliant (2011/65/EU) and REACH SVHC-free per Infineon's declaration dated June 2023. The device contains no lead, mercury, cadmium, hexavalent chromium, PBB, or PBDE, and meets JEDEC MSL1 reflow requirements up to 260 °C peak temperature.
