Product details

Overview

AUIRLR3636TRL from Infineon is an automotive-grade N-channel enhancement-mode HEXFET® Power MOSFET in D-Pak (TO-252AA) package, rated for 60 V V_DS, 5.4 mΩ R_DS(on) at V_GS = 10 V and 50 A continuous drain current (package-limited), with 175°C maximum junction temperature and logic-level gate drive compatibility. It serves as a high-efficiency main or synchronous rectifier switch in 12 V/24 V automotive power systems including engine control modules and DC-DC converters.

For engineers reviewing the AUIRLR3636TRL datasheet, AUIRLR3636TRL pinout, AUIRLR3636TRL application, or AUIRLR3636TRL equivalent, key selection criteria include its low R_DS(on) at 4.5 V gate drive (6.6 mΩ typ.), fast switching (t_r = 216 ns, t_f = 69 ns), repetitive avalanche rating (E_AR up to 200 mJ), and AEC-Q101 qualification for under-hood use.

Technical Context

This MOSFET employs Infineon's advanced silicon process to achieve ultra-low on-resistance per die area while maintaining robust thermal performance. Its gate threshold voltage (1.0–2.5 V) enables direct interface with 3.3 V and 5 V microcontrollers, and its internal gate resistance (0.6 Ω typ.) supports controlled turn-on/turn-off without external gate resistors in many designs.

The device integrates a fast, low-loss body diode (t_rr = 27 ns at T_J = 25°C, Q_rr = 31 nC) suitable for synchronous rectification and freewheeling in buck, boost, and half-bridge topologies. Its R_θJC of 1.05 °C/W allows high-power operation when mounted on copper-clad PCBs with thermal vias.

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
STL220N6F7	R_DS(on) = 2.2 mΩ @ 10 V, but DFN5x6 package limits thermal mass and peak current handling.	Better suited for space-constrained, lower-current (<30 A) modules where board area is critical.	Select when footprint size outweighs thermal derating needs; verify PCB copper area matches DFN thermal requirements.
IRLR3636TRLPBF	Same die and specs, but legacy marking; RoHS-compliant variant with identical AEC-Q101 certification and D-Pak packaging.	No functional difference - only part number revision and tape/reel labeling distinction.	Preferred for new designs requiring latest Infineon traceability and documentation; drop-in replacement for legacy builds.

Compared with STL220N6F7, AUIRLR3636TRL offers superior thermal robustness and higher continuous current (50 A vs. 30 A) in D-Pak, while IRLLR3636TRLPBF provides identical performance with updated compliance labeling-making it ideal for production continuity and audit readiness.

FAQ

What is the maximum continuous drain current for AUIRLR3636TRL at 100°C case temperature?

The maximum continuous drain current at T_C = 100°C is 70 A (silicon-limited), as specified in the Absolute Maximum Ratings table. This value assumes proper PCB thermal design with ≥1"² FR-4 copper area and still-air conditions. Derating begins at 0.95 W/°C beyond 25°C ambient, and actual usable current depends on layout, heatsinking, and duty cycle.

Does AUIRLR3636TRL support gate drive from a 3.3 V microcontroller?

Yes - its gate threshold voltage range is 1.0–2.5 V, and R_DS(on) is characterized down to V_GS = 4.5 V (6.6 mΩ typ.). While full enhancement occurs at ≥4.5 V, stable switching is achievable with 3.3 V logic when paired with low-capacitance gate drivers or reduced switching frequency to manage Q_g-related losses.

How is the body diode performance validated for synchronous rectification?

Body diode parameters are measured per JEDEC JESD24-11: t_rr = 27 ns and Q_rr = 31 nC at T_J = 25°C, with di/dt = 100 A/µs and V_R = 51 V. The diode forward voltage is 1.3 V at I_S = 50 A and T_J = 25°C. These values are confirmed in Figures 7 and 20 of the official datasheet and validated under AEC-Q101 stress testing.

Is AUIRLR3636TRL compatible with lead-free reflow soldering processes?

Yes - it is RoHS-compliant and qualified for lead-free reflow per IPC/JEDEC J-STD-020D. The maximum soldering temperature is 300°C for 10 seconds at 1.6 mm from the case, matching standard Pb-free profile requirements. The D-Pak package uses matte tin-plated leads compatible with SAC305 and other common lead-free alloys.
