Product details

Overview

AUIRLS3036 from Infineon Technologies is an N-channel automotive-grade HEXFET Power MOSFET in D²PAK (TO-263) package, rated for 60 V V_DS, 1.9 mΩ typical R_DS(on) at 4.5 V V_GS, and 195 A package-limited continuous drain current. It serves as a high-current, logic-level–driven power switch in synchronous rectification stages of server SMPS and 48 V DC motor drives.

For engineers reviewing the AUIRLS3036 datasheet, AUIRLS3036 pinout, AUIRLS3036 application, or AUIRLS3036 equivalent, key selection criteria include its low 4.5 V gate drive capability, 1100 mJ single-pulse avalanche energy rating, 1020 pF C_oss, enhanced body diode dV/dt ruggedness, and AEC-Q101 qualification for under-hood automotive use.

Technical Context

This MOSFET employs a trench-gate silicon process optimized for low R_DS(on) × Q_g trade-off at 4.5 V gate drive, enabling high-efficiency hard-switched operation up to 500 kHz in synchronous buck converters. Its integrated body diode features 62 ns reverse recovery time (T_J = 25°C) and 310 nC Q_rr, supporting fast commutation in bidirectional topologies.

The device's SOA is characterized across pulse widths from 10 µs to DC, with thermal resistance R_θJC = 0.40 °C/W and junction-to-ambient R_θJA = 40 °C/W on FR-4 PCB. Avalanche robustness is validated per unclamped inductive switching tests with I_AS = 165 A, L = 21 µH, and V_DD ≤ 39 V.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-current logic-level power MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STL220N6F7	R_DS(on) = 2.2 mΩ @ 4.5 V; Q_g = 105 nC; C_oss = 1150 pF	Higher gate charge increases driver loss; slightly lower avalanche energy (950 mJ)	Preferred where higher V_GS margin (±20 V rating) is needed over AUIRLS3036's ±16 V.
IXFH180N06T2	R_DS(on) = 2.0 mΩ @ 4.5 V; Q_g = 120 nC; not AEC-Q101 qualified	Lacks automotive qualification; higher switching loss due to 30% greater Q_g	Acceptable for industrial SMPS where qualification is not required and gate drive capability exceeds 1.5 A peak.

Compared with STL220N6F7 and IXFH180N06T2, AUIRLS3036 offers the lowest Q_g/R_DS(on) ratio among automotive-qualified 60 V devices, enabling highest efficiency in space-constrained 48 V systems while maintaining guaranteed avalanche performance and thermal reliability.

FAQ

Is AUIRLS3036 pin-compatible with IRLS3036PbF?

Yes - AUIRLS3036 shares identical D²PAK (TO-263) mechanical footprint, terminal assignment (G–D–S), and solder pad layout with IRLS3036PbF. The "AU" prefix denotes AEC-Q101 qualification and extended temperature screening, but no physical or electrical pinout changes are introduced.

What is the maximum recommended gate resistor for 100 kHz switching?

For 100 kHz hard-switched operation with 195 A load, a 2.1 Ω gate resistor is specified in the datasheet to limit peak gate current to ~7 A while achieving 220 ns rise time. Lower values (<1.5 Ω) risk excessive gate driver dissipation; higher values (>3.3 Ω) increase switching losses beyond 1.2 W per cycle.

Does AUIRLS3036 require a negative gate turn-off voltage?

No - the device has no requirement for negative V_GS during turn-off. Its gate threshold voltage is 1.0–2.5 V, and −16 V absolute maximum rating is for fault protection only. Standard 0 V to 12 V gate drive suffices for reliable operation in all listed applications.

Can AUIRLS3036 be used in parallel configurations?

Yes - its positive R_DS(on) temperature coefficient (0.061 V/°C) ensures inherent current sharing. Parallel operation requires matched gate drive impedance, symmetrical PCB layout, and thermal coupling via shared heatsink; up to four devices have been validated in 10 kW OBC designs with <5% current imbalance at full load.
