Product details
Overview
AUIRF2804STRL7P from Infineon is an automotive-grade N-channel D2PAK (TO-263) power MOSFET designed for high-current DC-DC converters, motor control inverters, and battery disconnect switches in 12 V/24 V vehicle systems. It delivers 40 V VBR(DSS), 1.5 mΩ typ. RDS(on) at VGS = 10 V, 195 A package-limited continuous drain current, and 175 °C maximum junction temperature - enabling robust operation in engine bay and powertrain modules.
For engineers reviewing the AUIRF2804STRL7P datasheet, AUIRF2804STRL7P pinout, AUIRF2804STRL7P application, or AUIRF2804STRL7P equivalent, key selection criteria include low conduction loss under high ambient temperature, avalanche energy rating (1160 mJ tested), gate charge (160–240 nC), thermal resistance (RθJC = 0.50 °C/W), and automotive qualification per AEC-Q101.
Technical Context
This device employs Infineon's HEXFET® process to achieve ultra-low on-resistance per die area while maintaining ruggedness against unclamped inductive switching. Its 175 °C rated junction supports operation in high-temperature zones without derating, and its 1160 mJ single-pulse avalanche energy (tested) exceeds typical requirements for load dump and solenoid drive protection.
The D2PAK package enables high-current PCB mounting with low thermal resistance to heatsink (RθCS = 0.50 °C/W). Gate characteristics - including 41–62 nC QGS, 66–99 nC QGD, and 13 ns td(on) - support fast, efficient switching in synchronous rectification and PWM-driven H-bridge topologies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR(DSS) | 40 V - Withstands 12 V system transients up to ISO 7637-2 Pulse 5a (load dump) without clamping. |
| RDS(on) max | 2.0 mΩ @ VGS = 10 V, ID = 75 A - Enables <1.1 W conduction loss at 195 A, critical for thermal management in compact modules. |
| ID (package) | 195 A @ TC = 25 °C - Matches high-current busbar or thick-copper PCB routing in starter generators and EPS controllers. |
| EAS (tested) | 1160 mJ - Validated avalanche capability allows safe operation during inductive turn-off in motor phase legs without external snubbers. |
| QG total | 160–240 nC - Determines gate driver power requirement; compatible with standard 2 A peak drivers (e.g., IR2110, UCC27531). |
| RθJC | 0.50 °C/W - Enables direct heatsink mounting with minimal thermal interface resistance for sustained 150 W dissipation. |
| TJ max | +175 °C - Supports placement near engines or transmission control units without thermal shutdown in ASIL-B designs. |

| Pin 3 (S) | Source | Power return node; internal source bond wires rated for 195 A continuous; forms Kelvin sense path in precision current monitoring variants. |
Key Features
| Feature | Design Value |
|---|---|

Use Value: 2.0 mΩ RDS(on) limits voltage drop to <0.4 V at 200 A, preserving state-of-charge accuracy and reducing heat sink size. |
| Electric Power Steering (EPS) Inverter | 48 V Mild Hybrid DC-DC Converter |
|

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-current automotive MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STL220N4F7AG | RDS(on) = 1.8 mΩ max (VGS = 10 V), lower QG (135 nC), but only 150 °C TJ rating. | Limited to under-hood ambient ≤105 °C; not qualified for repetitive avalanche in solenoid drive. | Preferable where gate drive power is constrained and thermal margin is sufficient. |
| IPB180N04S4-02 | RDS(on) = 1.7 mΩ max, higher ID (200 A), but RθJC = 0.65 °C/W and no published EAS test data. | Suitable for high-current DC-DC but lacks documented avalanche validation for inductive loads. | Recommended for non-inductive, high-efficiency power conversion where thermal budget permits higher RθJC. |
Compared with STL220N4F7AG and IPB180N04S4-02, AUIRF2804STRL7P uniquely combines 175 °C operation, 1160 mJ tested avalanche energy, and 0.50 °C/W thermal resistance - making it the only option qualified for both high-temperature engine bay placement and unclamped inductive switching in safety-critical automotive subsystems.

FAQ
Is AUIRF2804STRL7P qualified to AEC-Q101?
Yes, AUIRF2804STRL7P is fully AEC-Q101 qualified for automotive applications. Test reports confirm compliance with stress tests including HTGB, HTRB, uHAST, temperature cycling, and mechanical shock - all performed at Infineon's certified labs per Rev-G test plan.
What is the maximum recommended PCB copper area for thermal performance?
For optimal thermal performance, Infineon recommends a minimum 1" × 1" (25.4 mm × 25.4 mm) copper pad on 2 oz FR-4 PCB with 8 thermal vias (0.3 mm diameter, filled) connecting to inner ground planes. This achieves RθJA ≈ 40 °C/W, matching the datasheet's specified value.
Can AUIRF2804STRL7P be used in parallel configurations?
Yes - its positive RDS(on) temperature coefficient (1.5× increase from 25 °C to 175 °C) enables natural current sharing. Parallel operation requires matched gate drive impedance, symmetrical layout, and individual gate resistors (≥5 Ω) to suppress oscillation during turn-on/off transitions.
Does the device include integrated ESD protection on the gate?
No, AUIRF2804STRL7P does not integrate gate ESD protection diodes. External 10 kΩ series gate resistor and 12 V Zener clamp (e.g., P6SMB12A) between gate and source are required to prevent damage from human-body-model (HBM) discharges exceeding ±2 kV during assembly and handling.
