Product details
Overview
AUIRFR3710ZTRL from Infineon is an automotive-grade N-channel D-Pak power MOSFET with 100 V VDS, 18 mΩ max RDS(on) at VGS = 10 V, 42 A package-limited continuous drain current, and 175 °C maximum junction temperature-designed for high-efficiency DC-DC converters and motor control in engine management systems.
For engineers reviewing the AUIRFR3710ZTRL datasheet, AUIRFR3710ZTRL pinout, AUIRFR3710ZTRL application, or AUIRFR3710ZTRL equivalent, key selection criteria include avalanche energy rating (200 mJ tested), gate charge (69–100 nC), thermal resistance (1.05 °C/W junction-to-case), and automotive qualification per AEC-Q101.
Technical Context
This HEXFET® device employs advanced silicon process technology to achieve ultra-low on-resistance per die area while maintaining robust unclamped inductive switching capability. Its 175 °C rated junction enables operation in under-hood environments without derating penalties typical of commercial-grade MOSFETs.
The device supports fast switching (tr = 43 ns, tf = 42 ns) with low output capacitance (Coss = 290 pF at VDS = 25 V) and exhibits stable threshold voltage (2.0–4.0 V) across temperature, enabling reliable gate drive design in 12 V automotive battery systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| RDS(on) max | 18 mΩ @ VGS = 10 V, ID = 33 A - Enables <1.5 W conduction loss at 40 A in TO-252 footprint |
| ID (package) | 42 A @ TC = 25 °C - Matches PCB-mount thermal limits of standard 1"² FR-4 land pattern |
| EAS tested | 200 mJ - Validated single-pulse avalanche energy at TJ = 25 °C, L = 0.28 mH, IAS = 33 A |

IC Role / Device Role / Timing Role: Synchronous rectifier or pre-charge switch managing inrush current into bulk capacitors during AC plug-in. Use Value: 100 V VDS withstands 1.5× nominal bus voltage; low Coss (290 pF) minimizes switching loss at 100 kHz operation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel power MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STL130N10F7 | RDS(on) = 9.5 mΩ (lower), but VDS = 100 V, TJmax = 175 °C, Qg = 85 nC - higher gate charge increases driver loss | Not AEC-Q101 qualified; intended for industrial/commercial use only | Select only if automotive qualification is not required and lower conduction loss is prioritized over qualification compliance |
| IRF3710ZPBF | Same silicon die and RDS(on), but TO-220AB package - higher RθJA (62 °C/W) limits power density in space-constrained modules | Non-automotive grade; lacks AEC-Q101 validation and extended temperature characterization | Acceptable for prototyping or non-safety-critical 12 V systems where through-hole mounting is preferred |
Compared with STL130N10F7 and IRF3710ZPBF, AUIRFR3710ZTRL uniquely combines AEC-Q101 qualification, D-Pak thermal performance (1.05 °C/W), and validated 200 mJ avalanche energy-making it the only choice for production automotive power stages requiring both reliability and compactness.

FAQ
What is the maximum continuous drain current for AUIRFR3710ZTRL at 100 °C case temperature?
The maximum continuous drain current is 39 A at TC = 100 °C and VGS = 10 V, limited by silicon thermal saturation-not package constraints. This value is derived from the device's RDS(on) temperature coefficient and thermal resistance, ensuring safe operation without exceeding 175 °C junction temperature under sustained load.
Does AUIRFR3710ZTRL require a gate resistor for automotive 12 V systems?
Yes-a gate resistor between 2.2 Ω and 10 Ω is recommended to control dV/dt and prevent parasitic oscillation during switching. The device's 69–100 nC total gate charge and 25 nC gate-to-drain charge necessitate controlled turn-on/turn-off to avoid shoot-through in half-bridge configurations common in motor drivers.
Can AUIRFR3710ZTRL be used in synchronous rectification applications?
Yes-it supports synchronous rectification in 12 V DC-DC converters due to its low RDS(on) (15 mΩ typ.), fast body diode recovery (trr = 35–53 ns), and low Qrr (41–62 nC). However, external gate timing control is required since the device lacks integrated gate driver logic or adaptive dead-time control.
Is the exposed drain pad on AUIRFR3710ZTRL electrically isolated from the PCB ground plane?
No-the drain pad is electrically connected to the internal drain metallization and must be isolated from any conductive layer using solder mask-defined clearance or insulated thermal interface material. Direct connection to ground violates the device's 100 V isolation rating and risks short-circuit failure during transients.
