Product details

Overview

AUIRLS4030 from Infineon Technologies is an automotive-grade N-channel HEXFET® Power MOSFET in D2Pak (TO-263) package, rated for 100V V_DSS, 3.4mΩ typ. R_DS(on) at 10V V_GS, and 180A continuous drain current at T_C = 25°C. It serves as a high-efficiency main power switch in 12V/24V automotive DC-DC converters, motor control inverters, and battery disconnect circuits.

For engineers reviewing the AUIRLS4030 datasheet, AUIRLS4030 pinout, AUIRLS4030 application, or AUIRLS4030 equivalent, key selection criteria include its 175°C junction rating, 87nC total gate charge, 110A repetitive avalanche capability, logic-level gate drive compatibility down to 4.5V, and RoHS-compliant lead-free construction.

Technical Context

This MOSFET employs advanced planar silicon processing to achieve ultra-low on-resistance per die area while maintaining robust short-circuit withstand time and thermal stability. Its intrinsic body diode supports synchronous rectification with 50ns reverse recovery time and 88nC Q_rr at 25°C.

The device features a fully characterized dynamic capacitance profile: C_iss = 11360pF, C_oss = 670pF, and C_rss = 290pF at V_DS = 25V, enabling precise switching loss estimation in hard-switched topologies operating up to 100kHz.

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
STL220N10F7	100V, 2.2mΩ R_DS(on), 220A I_D, DFN8 5x6 package, no exposed drain tab	Higher current density but limited to PCB-only cooling; unsuitable for bolted heatsink mounting	Select when board space is constrained and thermal interface uses thermal vias + copper pour instead of mechanical heatsink
IRFB4115PBF	150V, 4.5mΩ R_DS(on), 110A I_D, TO-220 package, non-automotive grade	Lower voltage rating margin and no AEC-Q101 qualification; higher R_DS(on) increases conduction loss by ~33%	Select only for non-automotive industrial prototypes where cost is prioritized over qualification and thermal performance

Compared with STL220N10F7 and IRFB4115PBF, AUIRLS4030 uniquely balances automotive qualification, low R_DS(on), D2Pak thermal scalability, and logic-level drive-making it optimal for production-grade 12V/48V power stages requiring long-term reliability and field-proven ruggedness.

FAQ

What is the maximum gate-source voltage rating for AUIRLS4030?

The absolute maximum V_GS is ±16V. Operation beyond ±16V risks permanent gate oxide damage. Recommended gate drive is 4.5V to 15V, with 10V providing full enhancement and lowest R_DS(on). Gate resistors must limit dv/dt-induced ringing to avoid false turn-on during fast switching transitions.

Does AUIRLS4030 have an integrated body diode, and what are its key parameters?

Yes, it includes an integral p-n junction body diode with V_SD = 1.3V max at 110A and 25°C, t_rr = 50ns, and Q_rr = 88nC. This diode supports freewheeling in inductive loads and synchronous rectification, but is not rated for continuous reverse conduction above 110A due to thermal limits.

Can AUIRLS4030 be used in parallel configurations?

Yes, its positive R_DS(on) temperature coefficient (0.10%/°C) enables stable current sharing. Parallel operation requires matched gate drive layout, identical source inductance, and thermal coupling via shared heatsink. Derate total current by 15% for 2-device paralleling and 25% for 3+ devices to ensure thermal balance.

Is AUIRLS4030 compliant with lead-free soldering standards?

Yes, it is RoHS-compliant and qualified for lead-free reflow per J-STD-020 Rev E, with peak soldering temperature tolerance of 260°C for 10 seconds at 1.6mm from case. The D2Pak package supports both wave and reflow processes, and the exposed drain tab must be soldered to a thermal pad with ≥60% copper fill for optimal thermal performance.
