The AUIRLS3034-7TRL from Infineon Technologies is an automotive-grade N-channel power MOSFET built on advanced HEXFET® trench technology, delivering industry-leading low on-resistance in the D2PAK 7-pin package. Qualified to AEC-Q101 standards, this device is specifically engineered for demanding automotive power applications where reliability, efficiency, and thermal performance are critical. With a 40V drain-source voltage rating and 380A continuous drain current capability (silicon limited), the AUIRLS3034-7 achieves extremely low conduction losses with just 1.4mΩ maximum on-resistance at 10V VGS. The device supports logic-level gate drive with a gate threshold as low as 1.0V, enabling direct interface with 3.3V and 5V microcontroller outputs. Its high avalanche energy rating (250mJ single pulse) and robust body diode provide reliable performance in inductive switching applications. The 7-pin D2PAK package offers excellent thermal characteristics with 0.40°C/W junction-to-case thermal resistance, supporting efficient heat dissipation in compact designs. Supplied in tape-and-reel packaging (800 pieces per reel), the AUIRLS3034-7TRL is ideal for high-current automotive systems including electric power steering, motor drives, DC-DC converters, and power distribution modules.

The AUIRLS3034-7TRL operates as an N-channel enhancement-mode power MOSFET, functioning as a voltage-controlled switch. When a positive voltage is applied to the gate terminal relative to the source, an electric field forms beneath the gate oxide, creating an inversion layer (channel) in the p-type silicon body. This channel allows current to flow between the drain and source terminals. The HEXFET® trench technology forms the gate in vertical trenches etched into the silicon, enabling a much higher cell density than planar MOSFET structures, which directly translates to lower on-resistance per unit area. The device is turned on when VGS exceeds the gate threshold voltage VGS(th) of 1.0–2.5V, and is turned off when VGS drops below this threshold. During switching, the gate charge Qg represents the total charge required to charge and discharge the gate capacitance, and is a key parameter determining switching losses and drive circuit requirements. The body diode (formed by the p-body and n-drain junction) can conduct current from source to drain when forward biased, which is useful for freewheeling in motor drive and synchronous rectifier applications. The device features a robust body diode with fast recovery characteristics for high-frequency operation.

Pin Name Description
1-6 Source (S) Source terminals (pins 1-6 connected internally, multiple pins for high current carrying)
Tab Drain (D) Drain terminal (tab/heatsink, also pin 7 area)
7 Gate (G) Gate control terminal

Note: This is a D2PAK-7 (TO-263-7) package with 6 source pins, 1 gate pin, and the drain connected to the exposed tab for thermal dissipation. The 6 source pins are internally bonded together to handle high continuous and pulsed current levels up to 380A and 1540A respectively.
