It delivers a continuous drain current of 42 A at 25°C case temperature with a drain-source breakdown voltage of 40 V — a combination sized for high-current switching in 12 V and 24 V vehicle electrical systems: solenoid drivers, DC motor bridges, and load switches in body controllers or transmission ECUs. The through-hole TO-251AA (IPak) package suits wave-solder assembly and gives a low-inductance path to the PCB for the high di/dt edges. ## 4.9 mΩ Rds(on) — what it buys the power budget That keeps conduction losses under 9 W at full load — manageable with the 140 W package limit if the thermal path is right. The gate drive is rated for both 4.5 V and 10 V logic, so a 5 V microcontroller output can turn it on, though the Rds(on) roughly doubles at the lower drive voltage. Gate charge is 56 nC at 4.5 V, which means the driver sees a moderate capacitive load; a standard automotive pre-driver handles it without a separate gate resistor for damping. ## 175°C junction — engine-bay ready That covers cold crank at -40°C and under-hood soak at 150°C with margin. The input capacitance is 3810 pF at 25 V Vds — moderate for a 42 A device, so switching losses at 20 kHz PWM stay within the SOA without aggressive gate drive tuning. ## Active lifecycle, AEC-Q101 trace Listed as Active by Infineon — no NRND flag or last-time-buy notice on this code. The AEC-Q101 qualification means each wafer lot ships with traceability to the process control data, which is what automotive tier-1s require for PPAP submission. The -701TRL suffix denotes the tape-and-reel packing variant; the device itself is the same die as the tube-packed AUIRLU3114Z.","metaTitle":"Infineon AUIRLU3114Z-701TRL N-Channel MOSFET, 40V 42A","metaDescription":"Infineon AUIRLU3114Z-701TRL automotive N-channel HEXFET MOSFET. 40V Vdss, 42A continuous drain, 4.9mOhm Rds(on) at 10V.
