Product details
Overview
AUIRFR2407TRL from Infineon is an automotive-grade N-channel D-Pak (TO-252AA) HEXFET® Power MOSFET with 75 V V(BR)DSS, 21.8 mΩ typ. RDS(on) at VGS = 10 V and ID = 25 A, 42 A continuous drain current at TC = 25°C, fully avalanche rated, and qualified to AEC-Q101 for engine control, DC-DC converters, and motor drive circuits in under-hood environments.
For engineers reviewing the AUIRFR2407TRL datasheet, AUIRFR2407TRL pinout, AUIRFR2407TRL application, or AUIRFR2407TRL equivalent, key selection criteria include its 175°C junction rating, 5.0 V/ns diode recovery dv/dt capability, repetitive avalanche allowance up to Tjmax, low 1.4 °C/W RθJC, and automotive-compliant thermal and reliability validation.
Technical Context
This MOSFET employs Infineon's Stripe Planar HEXFET architecture optimized for low on-resistance per silicon area and fast switching-enabling high-efficiency synchronous rectification and PWM-controlled loads. Its body diode exhibits 100–150 ns trr and 400–600 nC Qrr at IF = 25 A, TJ = 25°C, supporting moderate-frequency hard-switched topologies.
The device operates across –55°C to +175°C junction range with ±20 V gate voltage tolerance, 2.0–4.0 V VGS(th), and dynamic parameters including 74–110 nC total gate charge and 16 ns turn-on delay under standard test conditions (VDD = 38 V, RG = 6.8 Ω).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| V(BR)DSS | 75 V - Withstands 75 V drain-source blocking voltage before avalanche conduction begins. |
| RDS(on) typ. | 21.8 mΩ @ VGS = 10 V, ID = 25 A - Enables <1.1 W conduction loss at 25 A, critical for thermally constrained automotive modules. |
| ID (TC = 25°C) | 42 A - Silicon-limited continuous drain current usable with adequate heatsinking at case temperature ≤25°C. |
| EAS | 130 mJ - Single-pulse avalanche energy rating ensures robustness against inductive switching transients in motor drives. |
| RθJC | 1.4 °C/W - Low junction-to-case thermal resistance supports high-power density mounting on copper-clad PCBs or heatsinks. |
| trr / Qrr | 100–150 ns / 400–600 nC - Body diode recovery performance suitable for non-resonant flyback and buck-boost converters. |
| dv/dt (diode) | 5.0 V/ns - Confirmed diode recovery dv/dt rating prevents spurious turn-on during high-slew-rate commutation. |

IC Role / Device Role / Timing Role: Power switch controlling injector coil energization/de-energization; must sustain repetitive avalanche during coil flyback. Use Value: 175°C rating enables placement near hot engine components; 21.8 mΩ RDS(on) minimizes I²R heating during extended duty cycles. | Use Scenario: Primary-side synchronous rectifier or high-side switch in 12 V → 5 V/3.3 V isolated DC-DC converters for infotainment and telematics modules. IC Role / Device Role / Timing Role: Main power switch operating at 200–500 kHz; requires low Qg and fast tr/tf to reduce gate drive loss and EMI. Use Value: 74–110 nC Qg and 90 ns rise time support efficient high-frequency operation while maintaining thermal margin. |

IC Role / Device Role / Timing Role: Low-side power switch modulating motor speed; must survive thermal cycling and vibration over 15-year vehicle life. Use Value: AEC-Q101 qualification and –55°C to +175°C operating range ensure long-term reliability in harsh cabin environments. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel automotive power MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STL220N4F7AG | 40 V V(BR)DSS, 1.6 mΩ RDS(on), PowerFLAT 5x6 package, lower voltage rating | Suitable only for 24 V systems; not interchangeable in 48 V or 75 V bus designs | Select only when system bus voltage ≤40 V and ultra-low RDS(on) is prioritized over voltage headroom. |
| IRF3207PbF | 75 V V(BR)DSS, 3.2 mΩ RDS(on), TO-220 package, non-automotive grade | Lacks AEC-Q101 qualification and 175°C rating; unsuitable for under-hood deployment | Acceptable for industrial bench prototypes but not for production automotive use due to reliability and qualification gaps. |
Compared with STL220N4F7AG and IRF3207PbF, AUIRFR2407TRL uniquely balances 75 V blocking, automotive qualification, D-Pak thermal efficiency, and proven avalanche ruggedness-making it the only validated choice for production 12 V/24 V engine bay power stages requiring long-term reliability.

FAQ
What is the maximum allowable gate-to-source voltage for AUIRFR2407TRL?
The absolute maximum VGS is ±20 V. Exceeding this rating-even briefly-can cause irreversible gate oxide damage. Gate drive circuits must clamp voltage within this range using Zener diodes or active clamping, especially during fast switching or inductive load transients where ringing may occur.
Is AUIRFR2407TRL suitable for synchronous rectification in isolated DC-DC converters?
Yes-its 21.8 mΩ RDS(on), low Qrr (400–600 nC), and 100–150 ns trr support efficient synchronous rectification at frequencies up to 300 kHz. However, body diode conduction must be minimized via precise gate timing to avoid reverse recovery losses.
Does AUIRFR2407TRL require a heatsink in typical automotive applications?
At 25 A continuous drain current, junction temperature rise is ~35°C above case temperature (using RθJC = 1.4 °C/W). A modest copper pour (≥1 in²) is sufficient for most applications; forced-air or bolted heatsinks are needed only when TC exceeds 100°C or power dissipation exceeds 40 W.
How does the repetitive avalanche rating impact circuit design?
The 11 mJ repetitive avalanche energy rating allows safe operation during repeated inductive turn-off events-such as fuel injector coil de-energization-without external snubbers, provided pulse width and duty cycle stay within limits defined by TJmax and thermal time constants.
