Product details
Overview
IRFS7730-7PPBF from Infineon Technologies (formerly International Rectifier) is a 75 V, 240 A (package-limited), N-channel enhancement-mode HEXFET® Power MOSFET in D2PAK-7L package with 1.70 mΩ typical RDS(on) at VGS = 10 V, optimized for high-current synchronous rectification and half/full-bridge motor drive topologies in battery-powered and resonant-mode power supplies.
For engineers reviewing the IRFS7730-7PPBF datasheet, IRFS7730-7PPBF pinout, IRFS7730-7PPBF application, or IRFS7730-7PPBF equivalent, key selection criteria include avalanche energy rating (897 mJ), gate charge (285 nC typ.), body diode dV/dt ruggedness (11 V/ns), and thermal resistance (0.40 °C/W junction-to-case).
Technical Context
This device employs a trench-gated, superjunction-enhanced silicon structure delivering low conduction loss while maintaining robust unclamped inductive switching capability. Its fully characterized avalanche SOA supports repetitive operation up to 175 °C junction temperature with validated EAS of 897 mJ under 1 mH inductance and 42 A IAS.
The integrated body diode features enhanced dI/dt (1575 A/µs) and reverse recovery performance (Qrr = 63 nC at 25 °C), enabling reliable OR-ing and synchronous rectifier use without external Schottky supplementation in DC/DC converters.
Key Specifications

|---|---|
| VDSS | 75 V - Maximum blocking voltage before avalanche onset; enables use in 48 V and 60 V bus systems with margin. |
| RDS(on) max | 2.00 mΩ - Ensures ≤ 4.8 W conduction loss at 240 A continuous drain current with minimal thermal rise. |
| ID (package) | 240 A - Package-limited continuous current at TC = 25 °C; defines PCB copper and heatsink sizing requirements. |
| EAS | 897 mJ - Single-pulse avalanche energy at TJ = 25 °C, L = 1 mH, IAS = 42 A; validates robustness in inductive load switching. |
| Qg typ. | 285 nC - Total gate charge at VDS = 38 V, ID = 100 A; determines driver strength requirement and switching loss trade-off. |
| dv/dt (diode) | 11 V/ns - Peak diode recovery dv/dt rating at TJ = 175 °C; critical for noise immunity in fast-switching inverters. |
| RθJC max | 0.40 °C/W - Junction-to-case thermal resistance; enables precise heatsink thermal design for 375 W PD dissipation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-current N-channel power MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STL220N7F3AG | 75 V, 220 A, 1.85 mΩ RDS(on), TO-220FP-7L package; higher RθJA (40 °C/W), no Kelvin source. | Limited to lower-frequency (< 100 kHz) motor drives due to higher gate charge (330 nC) and absence of SG pin. | Prefer when cost-sensitive, lower-volume designs require through-hole mounting and simplified gate drive. |
| IXFH70N75X3 | 75 V, 70 A, 7.5 mΩ RDS(on), TO-247-3L; 10× higher RDS(on), but rated for 100% avalanche energy (1200 mJ). | Suitable only for lower-current, ultra-rugged applications where avalanche survival outweighs conduction loss. | Select only when primary requirement is absolute avalanche immunity over efficiency-e.g., aerospace-grade protection circuits. |
Compared with STL220N7F3AG and IXFH70N75X3, IRFS7730-7PPBF uniquely combines sub-2 mΩ on-resistance, Kelvin-source sensing, and 897 mJ avalanche energy in a surface-mount D2PAK-7L package-making it optimal for high-density, high-efficiency motor and power conversion designs demanding both performance and reliability.

FAQ
What is the maximum continuous drain current for IRFS7730-7PPBF at 100°C case temperature?
The maximum continuous drain current at TC = 100 °C is 190 A (silicon-limited), as specified in the Absolute Maximum Ratings table. This value reflects thermal derating from the 240 A package limit at 25 °C, based on 2.5 W/°C linear derating factor and 375 W maximum power dissipation.
Does IRFS7730-7PPBF support Kelvin-source sensing, and how is it implemented?
Yes-IRFS7730-7PPBF includes a dedicated SG (Source Kelvin) pin separate from the main source terminals. This allows gate-drive circuitry to reference VGS directly to the source potential at the die, eliminating voltage drop errors caused by bond-wire and PCB trace resistance during high di/dt switching.
How does the body diode performance compare to standard Schottky rectifiers in synchronous rectification?
Its body diode delivers 1.2 V forward voltage at 100 A and 25 °C, with 63 nC Qrr and 42 ns trr-comparable to medium-voltage Schottkys. While forward drop is higher than Schottky, its integrated nature, avalanche rating, and Kelvin-source compatibility make it superior for high-current, high-reliability synchronous rectifier designs where discrete diodes add layout complexity and parasitic inductance.
Can IRFS7730-7PPBF be used in paralleled configurations, and what layout considerations apply?
Yes-the D2PAK-7L package with three source pins and dual drain connections is explicitly designed for paralleling. Critical layout practices include symmetrical gate drive routing with matched trace lengths, individual gate resistors per device, and shared thermal plane under the exposed drain pad to ensure current sharing and thermal balance across multiple units.
