Product details
Overview
AUIRFS8407-7P from Infineon Technologies (formerly International Rectifier) is an automotive-grade N-channel D2Pak-7PIN HEXFET® Power MOSFET designed for high-current, low-voltage switching in safety-critical power paths. It delivers 40V VDS, 1.0 mΩ typ. RDS(on) at VGS = 10V, 240A package-limited continuous drain current, and 175°C maximum junction temperature - enabling robust operation in electric power steering, battery disconnect, and start-stop micro-hybrid systems.
For engineers reviewing the AUIRFS8407-7P datasheet, AUIRFS8407-7P pinout, AUIRFS8407-7P application, or AUIRFS8407-7P equivalent, key selection criteria include its ultra-low on-resistance under high-temperature bias, validated repetitive avalanche capability up to Tjmax, and D2Pak-7PIN thermal performance with 0.65°C/W RθJC.
Technical Context
This MOSFET employs advanced silicon processing to achieve sub-1.3 mΩ RDS(on) while sustaining 175°C junction operation - critical for under-hood automotive environments. Its gate charge profile (Qg = 150–225 nC) and low Ciss (7437 pF) support fast, efficient hard-switching in DC-DC converters and motor control inverters.
The integrated body diode exhibits 37 ns reverse recovery time (Tj = 25°C), 34 nC Qrr, and 3.5 V/ns peak dv/dt immunity - enabling reliable freewheeling in inductive loads without external snubbers. Repetitive avalanche energy (EAR) is rated per JEDEC AEC-Q101 conditions, with validated safe operating area up to 100A at 40V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 40 V - Maximum blocking voltage for 12V/24V automotive battery rail protection and load switching. |
| RDS(on) typ. | 1.0 mΩ @ VGS = 10V, Tj = 25°C - Enables <1.0 W conduction loss at 100A, reducing heatsink requirements. |
| ID (Package) | 240 A @ TC = 25°C - Package-limited current defines PCB trace and mounting design for high-power battery switches. |
| EAS (tested) | 508 mJ - Single-pulse avalanche energy rating verified per IRF test conditions (L = 0.069 mH, IAS = 100A). |
| RθJC | 0.65 °C/W - Junction-to-case thermal resistance enables direct heatsink mounting for >1 kW power dissipation. |
| Qg | 150–225 nC - Total gate charge determines driver strength requirement for <100 ns switching transitions. |
| Tj max | 175°C - Automotive-grade junction temperature rating supports operation in engine bay enclosures. |
Pinout & Package
Supplied in a surface-mount D2Pak-7PIN (TO-263-7) package with exposed drain pad for enhanced thermal transfer. The 7-pin configuration includes three source terminals (S), one gate (G), and three drain terminals (D) - optimized for parallel bond-wire current sharing and low-inductance PCB layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| G | Gate | Control input; requires 10V drive for full enhancement; internal RG = 2.2 Ω limits ringing. |
| D (Pins 1, 2, 7) | Drain | High-current power output node; pins 1, 2, and 7 are internally connected to the exposed drain pad. |
| S (Pins 3, 4, 6) | Source | Power return path; three parallel pins reduce source inductance and improve current sharing in paralleled configurations. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low RDS(on) | 1.0 mΩ typ. at 100A/10V - reduces conduction losses by >40% vs. legacy 40V automotive MOSFETs. |
| Repetitive avalanche rating | Validated up to Tjmax - allows safe operation during unclamped inductive switching events without derating. |
| 175°C junction rating | Qualified per AEC-Q101 - ensures reliability in under-hood ambient temperatures exceeding 125°C. |
| Fast body diode recovery | trr = 37 ns, Qrr = 34 nC - minimizes switching losses and EMI in synchronous rectification and H-bridge topologies. |
| D2Pak-7PIN thermal design | RθJC = 0.65°C/W - enables >1.5 kW pulsed power handling with standard heatsink mounting. |
Applications

IC Role / Device Role / Timing Role: High-current bidirectional switch in 12V/48V bi-directional DC-DC converter for energy recovery. Use Value: Low Qg (150 nC) and fast switching (tf = 51 ns) minimize dead-time losses during frequent start/stop transitions. |
Use Scenario: Primary-side synchronous rectifier switch in 48V-to-12V buck converter for next-gen vehicle architectures. IC Role / Device Role / Timing Role: High-frequency (100–300 kHz), high-duty-cycle power switch requiring low Coss and stable RDS(on) over temperature.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-current automotive power switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STL220N4F7AG | 40V, 220A, RDS(on) = 1.2 mΩ, DFN8 5x6 package, RθJC = 0.8°C/W | Limited to lower peak current due to smaller thermal interface; not qualified for 175°C continuous operation. | Preferred for space-constrained PCBs where thermal budget allows 0.15°C/W higher junction rise. |
| IXTH30N40P | 400V, 30A, RDS(on) = 140 mΩ, TO-247 package, RθJC = 0.4°C/W | Higher voltage rating but 14× higher RDS(on); unsuitable for <50A continuous automotive loads. | Only viable if system requires 400V isolation margin and can accept >10× higher conduction loss. |
Compared with STL220N4F7AG and IXTH30N40P, AUIRFS8407-7P uniquely balances ultra-low on-resistance, 240A package current, and 175°C junction rating - making it the only option qualified for sustained high-power EPS and battery-switching duty cycles in AEC-Q101-compliant designs.

FAQ
What is the maximum continuous drain current for AUIRFS8407-7P at 100°C case temperature?
The continuous drain current is 216A at TC = 100°C and VGS = 10V, as specified in the Absolute Maximum Ratings table. This reflects silicon-limited current derating due to thermal constraints, distinct from the 240A package-limited rating at 25°C.
Does AUIRFS8407-7P support logic-level gate drive?
No - its gate threshold voltage (VGS(th)) ranges from 2.2V to 3.9V, but full enhancement requires VGS ≥ 10V to achieve the rated 1.0 mΩ RDS(on). Driving at 5V yields significantly higher on-resistance and is not recommended for high-current operation.
How is the D2Pak-7PIN pinout configured for PCB layout optimization?
Pins 1, 2, and 7 are internally bonded to the exposed drain pad; pins 3, 4, and 6 connect to source; pin 5 is the gate. This triple-source/triple-drain layout minimizes parasitic inductance and enables symmetric current distribution - critical for minimizing voltage spikes in high-di/dt EPS and battery-switching applications.
Is repetitive avalanche operation validated per AEC-Q101?
Yes - the device is qualified for repetitive avalanche up to Tjmax under conditions defined in AN-1005, with energy curves (Fig. 15) and current-vs.-pulsewidth limits (Fig. 14) provided in the datasheet. Operation must stay within the SOA boundary where ΔTj does not exceed 150°C above ambient.
