Product details
Overview
IRF7463TRPBF from Infineon Technologies (formerly International Rectifier) is a 30V, 8mΩ, 14A N-channel dual MOSFET in SO-8 package, optimized for synchronous rectification in high-frequency DC-DC converters. It features ultra-low RDS(on) at 4.5V gate drive, fully characterized avalanche capability (320mJ), and integrated body diode with 45ns reverse recovery time. Used in telecom and industrial isolated power supplies.
For engineers reviewing the IRF7463TRPBF datasheet, IRF7463TRPBF pinout, IRF7463TRPBF application, or IRF7463TRPBF equivalent, key selection criteria include low-voltage gate drive compatibility (2.7V–10V), junction-to-ambient thermal resistance (50°C/W), SO-8 footprint suitability for high-density layouts, and avalanche-rated operation in unclamped inductive switching.
Technical Context
This dual N-channel MOSFET integrates two identical die in a single SO-8 package, sharing source terminals (pins 5–8) and enabling complementary high-side/low-side or parallel configurations. Its 8mΩ RDS(on) at VGS = 10V and 9.5mΩ at VGS = 4.5V supports efficient synchronous rectification in buck and flyback topologies operating above 300kHz.
The device exhibits 34nC total gate charge and 180pF reverse transfer capacitance (Crss), enabling fast switching with minimal Miller-induced shoot-through risk. Avalanche robustness (14A IAR, 320mJ EAS) allows reliable operation under transient overcurrent conditions without external snubbers.

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel dual MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Si7852DP-T1-GE3 | RDS(on) = 7.5mΩ @ 10V but higher Qg (42nC); SO-8 with separate sources | Requires modified PCB layout due to non-shared source pins; better for independent channel control | Prefer when gate drive strength exceeds 1A and source isolation is needed for current sensing |
| DMN3025LSD-13 | Lower RDS(on) (6.5mΩ @ 10V) but no avalanche rating; 30V rating same, SO-8 package | Not rated for unclamped inductive switching; unsuitable for flyback or forward converters with leakage spikes | Select only for regulated buck converters with tight voltage clamping and <100ns turn-off timing control |
Compared with Si7852DP-T1-GE3 and DMN3025LSD-13, IRF7463TRPBF uniquely balances low RDS(on), controlled gate charge, and certified avalanche ruggedness-making it optimal for telecom and industrial isolated converters where reliability under transient stress is non-negotiable.

FAQ
What is the maximum continuous drain current at 70°C ambient temperature?
The IRF7463TRPBF supports 11A continuous drain current at TA = 70°C with standard SO-8 mounting on 1in² copper. This rating assumes no forced airflow and accounts for thermal derating of 0.02mW/°C beyond 25°C ambient. At 70°C, power dissipation is limited to 1.6W, consistent with its RDS(on) and thermal resistance profile.
Does IRF7463TRPBF support 3.3V gate drive in practical designs?
Yes-IRF7463TRPBF delivers 20mΩ RDS(on) at VGS = 2.7V and 14A ID, making it functional with 3.3V logic-level gate drivers. However, full performance (8mΩ) requires ≥10V drive; for 3.3V systems, verify that peak current demand stays below 7A to maintain acceptable conduction loss and junction temperature.
How is the SO-8 package thermally enhanced for power dissipation?
The SO-8 package uses pins 1–4 and 6–7 as exposed drain terminals, providing direct thermal paths to PCB copper pours. With 1in² of 2oz copper and 6 thermal vias, junction-to-ambient resistance drops from 50°C/W to ~22°C/W. The package outline conforms to JEDEC MS-012AA, ensuring compatibility with standard reflow profiles and pick-and-place equipment.
Can IRF7463TRPBF be used in parallel configurations?
Yes-the dual-die structure and matched RDS(on) characteristics (±10% typical) enable stable current sharing when paralleled. Use individual gate resistors (≤10Ω) and symmetrical PCB routing to minimize imbalance. Derate total current by 15% versus sum of individual ratings to account for thermal coupling between devices on shared copper areas.
