Product details

Overview

IPP50N10S3L16AKSA1 from Infineon Technologies is an N-channel enhancement-mode OptiMOS™-T power MOSFET in PG-TO220-3-1 package, rated for 100 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 is AEC-Q101 qualified, supports 175 °C operation, and features 100% single-pulse avalanche testing - used in automotive DC-DC converters and motor control H-bridge high-side switches.

For engineers reviewing the IPP50N10S3L16AKSA1 datasheet, IPP50N10S3L16AKSA1 pinout, IPP50N10S3L16AKSA1 application, or IPP50N10S3L16AKSA1 equivalent, key selection criteria include R_DS(on) at 4.5 V/10 V, avalanche energy (E_AS = 330 mJ), thermal resistance (R_thJC = 1.5 K/W), diode forward voltage (V_SD = 0.6–1.2 V), and gate charge (Q_g = 49–64 nC).

Technical Context

This MOSFET employs trench-gate silicon technology optimized for low conduction and switching losses in hard-switched 12 V/24 V automotive systems. Its gate threshold voltage (V_GS(th) = 1.2–2.4 V) enables robust TTL/CMOS-level drive compatibility, while the integrated body diode exhibits fast reverse recovery (t_rr = 80 ns, Q_rr = 185 nC) and low forward drop (V_SD ≤ 1.2 V at 50 A).

The device operates with a maximum junction temperature of 175 °C and is qualified per AEC-Q101 Rev D. Thermal performance is defined by R_thJC = 1.5 K/W and R_thJA = 62 K/W (leaded), enabling stable operation under pulsed loads up to I_D,pulse = 200 A and avalanche stress up to E_AS = 330 mJ at I_D = 25 A.

Key Specifications

Parameter	Value and Actual Design Meaning

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
IPP50N10S3-16	No AEC-Q101 qualification; identical R_DS(on), V_DS, and package	Not approved for automotive safety-critical systems; suitable for industrial/commercial use only	Select when automotive qualification is not required and cost optimization is prioritized
IPB50N10S3L-16	PG-TO263-3-2 package (D²PAK); same electrical specs and AEC-Q101 grade	Surface-mount assembly; higher thermal resistance (R_thJC = 1.6 K/W) than TO220 variant	Choose for automated SMT lines where board space and reflow compatibility outweigh thermal margin

Compared with IPP50N10S3L16AKSA1, IPP50N10S3-16 lacks automotive qualification but offers identical performance in non-automotive settings, while IPB50N10S3L-16 trades through-hole ease-of-use and lower R_thJC for SMT manufacturability - both require layout and thermal redesign.

FAQ

What is the maximum allowable gate-source voltage for IPP50N10S3L16AKSA1?

The absolute maximum gate-source voltage is ±20 V. Operation beyond this range risks permanent oxide damage. Recommended drive is 10 V for full enhancement and minimal R_DS(on), with 4.5 V sufficient for logic-level control in low-voltage systems. Gate resistors should limit dV/dt to avoid spurious turn-on during high-di/dt events.

Does IPP50N10S3L16AKSA1 include an integrated body diode, and what are its key parameters?

Yes, it integrates a fast-recovery epitaxial body diode rated for 50 A continuous forward current and 200 A pulsed current. Key parameters include V_SD = 0.6–1.2 V at 50 A and 25 °C, t_rr = 80 ns, and Q_rr = 185 nC under specified test conditions (V_R = 50 V, di/dt = 100 A/µs). This diode supports synchronous rectification and freewheeling in bridge topologies.

How does the thermal resistance R_thJC = 1.5 K/W impact heatsink selection?

With R_thJC = 1.5 K/W and a maximum junction temperature of 175 °C, a 100 °C case temperature allows 50 W of power dissipation before thermal limiting. For 50 A continuous operation, a heatsink with R_thCS + R_thSA ≤ 1.0 K/W is recommended to maintain safe margins under worst-case ambient and airflow conditions.

Is IPP50N10S3L16AKSA1 suitable for use in linear mode (saturation region) applications?

No - this device is optimized for switching operation, not linear mode. Its Safe Operating Area (SOA) curve shows limited DC capability above 10 V V_DS; sustained linear operation risks thermal runaway due to positive temperature coefficient of R_DS(on). It must be operated in saturation only for brief transitions, not steady-state regulation.
