Product details
Overview
AUIRFP2907Z from Infineon Technologies is an automotive-grade N-channel enhancement-mode HEXFET® Power MOSFET in TO-247AC package, rated for 75 V V(BR)DSS, 4.5 mΩ RDS(on) max at 10 V VGS, and 170 A continuous drain current at 25°C. It features 175°C maximum junction temperature, repetitive avalanche capability up to TJmax, and ultra-low on-resistance optimized for high-efficiency DC-DC conversion and motor drive stages in engine control units.
For engineers reviewing the AUIRFP2907Z datasheet, AUIRFP2907Z pinout, AUIRFP2907Z application, or AUIRFP2907Z equivalent, key selection criteria include its 75 V breakdown voltage, 4.5 mΩ on-resistance, 180 nC total gate charge, 175°C thermal rating, and AEC-Q101 qualification - all critical for high-current, high-temperature automotive power switching.
Technical Context
This MOSFET employs advanced planar silicon process technology to achieve low RDS(on) per die area while maintaining robust avalanche performance. Its gate threshold voltage (2.0–4.0 V) enables direct 3.3 V/5 V logic-level drive compatibility when paired with appropriate gate drivers, and its 13 nH internal source inductance supports fast switching with controlled di/dt.
The device integrates a co-packaged body diode with 1.3 V forward voltage and 41–61 ns reverse recovery time, enabling synchronous rectification and freewheeling in half-bridge topologies. Repetitive avalanche operation is thermally limited and validated per Fig. 12a–16 under defined L=0.13 mH, RG=25 Ω, IAS=90 A conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| V(BR)DSS | 75 V - Withstands up to 75 V drain-source blocking voltage before avalanche onset, suitable for 48 V automotive systems and 24 V battery-fed inverters. |
| RDS(on) max | 4.5 mΩ @ VGS = 10 V, TJ = 25°C - Enables <1 W conduction loss at 150 A, reducing heatsink requirements in high-current motor drives. |
| ID @ TC = 25°C | 170 A - Supports peak load currents in starter solenoid drivers and electric power steering H-bridges without derating. |
| EAS (tested) | 520 mJ - Validated single-pulse avalanche energy ensures robustness against inductive turn-off transients in relay and solenoid control. |
| Qg | 180–270 nC - Determines gate driver power requirement; ~2.7 mJ energy needed per full switch cycle at 15 V drive. |
| TJ max | 175°C - Allows operation in under-hood environments without forced cooling, meeting ASIL-B thermal safety margins. |
| Qualification | AEC-Q101 qualified - Certified for automotive use with MSL1, HBM Class H2 (4 kV), and CDM Class C5 (1.125 kV) ESD robustness. |

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 | 75 V V(BR)DSS, 3.2 mΩ RDS(on), TO-247-3L package, 150 A ID, no AEC-Q101 certification | Industrial-grade only; lacks automotive qualification and repetitive avalanche validation | Acceptable for non-safety-critical 48 V industrial converters where AEC-Q101 is not mandated. |
| IXFH75N30P3 | 300 V V(BR)DSS, 12.5 mΩ RDS(on), TO-247 package, 75 A ID, AEC-Q101 qualified | Higher voltage rating but higher on-resistance and lower current capacity limits use in 48 V systems | Preferred only when system requires >100 V blocking margin or legacy 300 V design reuse. |

FAQ
What is the maximum continuous drain current at 100°C case temperature?
The AUIRFP2907Z supports 120 A continuous drain current at TC = 100°C with VGS = 10 V, as specified in the Absolute Maximum Ratings table. This derating reflects thermal limitations of the TO-247AC package and must be applied when heatsink ambient exceeds 70°C or airflow is restricted.
Does AUIRFP2907Z require a gate resistor for safe operation?
Yes - a gate resistor (typically 5–25 Ω) is required to control dv/dt and di/dt during switching, prevent oscillation, and limit peak gate current. The datasheet specifies RG = 25 Ω for avalanche testing and recommends matching gate driver output impedance to minimize ringing in high-frequency PWM applications.
Can AUIRFP2907Z replace older IRFP2907 in existing designs?
No - AUIRFP2907Z is the automotive-qualified variant with tighter parameter distributions, enhanced avalanche testing, and AEC-Q101 certification, whereas IRFP2907 is industrial-grade. While electrically compatible, replacement requires revalidation of thermal, EMI, and functional safety compliance per ISO 26262.
What is the significance of the "Z" suffix in AUIRFP2907Z?
The "Z" suffix denotes Infineon's automotive-grade packaging and screening: lead-free (RoHS-compliant), MSL1 moisture sensitivity level, and full AEC-Q101 qualification including extended temperature cycling, mechanical shock, and accelerated life testing per automotive reliability standards.
