Product details
Overview
IRF2804STRL-7P from Infineon Technologies (formerly International Rectifier) is an N-channel automotive-grade HEXFET® Power MOSFET in D2PAK (TO-263) package, rated for 40V VDSS, 1.2–1.6 mΩ RDS(on) at VGS = 10 V, and 160 A continuous drain current at TC = 25°C. It delivers ultra-low conduction loss, 175°C junction operation, and robust repetitive avalanche capability up to TJmax, making it suitable for high-current DC motor drives and battery disconnect circuits in 12 V/24 V automotive systems.
For engineers reviewing the IRF2804STRL-7P datasheet, IRF2804STRL-7P pinout, IRF2804STRL-7P application, or IRF2804STRL-7P equivalent, key selection considerations include its 1.6 mΩ on-resistance at 160 A, 260 nC total gate charge, 175°C thermal rating, and D2PAK thermal performance with RθJC = 0.50°C/W - critical for high-power switching in engine control units and electric power steering modules.
Technical Context
This MOSFET employs advanced silicon processing to minimize RDS(on) per die area while maintaining ruggedness under unclamped inductive switching. Its gate threshold voltage (2.0–4.0 V) enables direct drive from standard 3.3 V/5 V logic with adequate margin, and its 970 pF Crss supports stable high-frequency PWM operation up to 100 kHz in synchronous rectification.
The device integrates a fast, low-VSD (≤1.3 V) body diode with 43–65 ns reverse recovery time and 48–72 nC Qrr, enabling efficient freewheeling in H-bridge motor drivers without external Schottky supplementation. Thermal design is anchored by validated transient impedance curves (Fig. 11) and 100% production-tested EAS of 630 mJ.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 40 V - Maximum blocking voltage compatible with 12 V/24 V automotive battery rails including load dump transients. |
| RDS(on) max | 1.6 mΩ @ VGS = 10 V, TJ = 25°C - Enables ≤256 mW conduction loss at 160 A, reducing heatsink requirements. |
| ID cont | 160 A @ TC = 25°C - Supports high-current loads such as starter relays and HVAC blowers without parallel devices. |
| EAS | 630 mJ - 100% production-tested single-pulse avalanche energy, allowing safe operation during inductive turn-off spikes. |
| Qg | 260 nC max - Determines gate driver power requirement; ~2.6 W average drive power at 100 kHz and 15 V swing. |
| TJ max | 175°C - Enables sustained operation in under-hood environments without derating below ambient +150°C. |
| Ciss | 6930 pF - Input capacitance defining Miller effect and gate drive loop stability in hard-switched topologies. |
Pinout & Package
IRF2804STRL-7P uses the surface-mount D2PAK (TO-263) package with exposed drain pad for low thermal resistance. The three terminals are arranged in standard configuration: Pin 1 = Gate, Pin 2 = Drain (tab), Pin 3 = Source.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Gate (G) | Control input | Receives 10 V logic-level signal to fully enhance channel; 2.0–4.0 V VGS(th) ensures compatibility with microcontroller GPIOs. |
| Drain (D) | High-side or low-side power path | Exposed copper tab serves as primary current path and thermal interface; must be soldered to PCB copper pour for RθJC = 0.50°C/W. |
| Source (S) | Reference node / return path | Connected to system ground or low-side shunt; internal source inductance (7.5 nH) impacts switching ringing in high-di/dt applications. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low RDS(on) | 1.2 mΩ typical at 10 V gate drive - reduces I²R losses by >30% versus prior-gen 40 V MOSFETs at 160 A. |
| 175°C junction rating | Rated continuous operation up to 175°C - eliminates need for thermal shutdown circuitry in engine bay mounting. |
| Fast switching | 17 ns turn-on delay + 105 ns fall time - supports >50 kHz PWM in BLDC motor inverters with minimal dead-time penalty. |
| Repetitive avalanche rated | Validated up to TJmax per Fig. 15/16 - enables reliable operation in unclamped inductive loads like solenoid drivers without snubbers. |
| Automotive-qualified | AEC-Q101 stress-tested - qualified for use in safety-critical subsystems including EPS and transmission control. |

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 |
|---|---|---|---|
| STL220N4F7AG | 40 V, 0.95 mΩ RDS(on), DFN8 5×6 mm package, no exposed drain tab | Limited to PCB-constrained thermal designs; lacks D2PAK's 0.50°C/W RθJC | Select when board space is critical and peak current ≤120 A; requires enhanced copper pour for thermal management. |
| IXTH160N40L2 | 40 V, 1.8 mΩ RDS(on), TO-247 package, higher Qg (320 nC) | Through-hole mounting only; slower switching due to higher gate charge | Prefer for legacy through-hole designs where D2PAK rework is not feasible; accept 20% higher gate drive loss. |
Compared with STL220N4F7AG and IXTH160N40L2, IRF2804STRL-7P offers optimal balance of ultra-low RDS(on), proven D2PAK thermal performance, and automotive qualification - making it the preferred choice for new high-current automotive power stages where reliability and thermal headroom are prioritized over footprint minimization.

FAQ
What is the maximum continuous drain current at 100°C case temperature?
The IRF2804STRL-7P supports 230 A continuous drain current at TC = 100°C per Absolute Maximum Ratings table (Page 2). This value reflects package-limited current handling under forced convection or high-efficiency heatsinking, distinct from the 160 A silicon-limited rating at 25°C.
Does this MOSFET require a gate resistor for automotive 12 V applications?
Yes - a gate resistor (typically 2.6–10 Ω) is required to control dV/dt and suppress ringing caused by 7.5 nH internal source inductance and PCB layout parasitics. The datasheet specifies RG = 2.6 Ω for switching time characterization (Page 3), and values above 10 Ω significantly increase switching losses.
Is the body diode suitable for synchronous rectification in a 40 V buck converter?
No - while the body diode has low VSD (≤1.3 V) and fast trr (43–65 ns), its Qrr (48–72 nC) is too high for efficient synchronous rectification above 100 kHz. External Schottky or GaN FETs are recommended for high-frequency, high-efficiency secondary-side switching.
Can IRF2804STRL-7P replace IRF2804SPBF in existing designs?
Yes - both share identical electrical specifications, D2PAK package, and automotive qualification. IRF2804STRL-7P is the tape-and-reel version optimized for automated SMT assembly, whereas IRF2804SPBF is the bulk-packaged variant. No layout or thermal redesign is needed for drop-in substitution.
