Product details
Overview
IRF8304MTRPBF from Infineon Technologies is a 30 V, 28 A N-channel DirectFET® MOSFET in MX package with 1.7 mΩ RDS(on) @ 10 V, 28 nC total gate charge, and ultra-low 0.7 mm profile optimized for synchronous buck converters in CPU core power delivery.
For engineers reviewing the IRF8304MTRPBF datasheet, IRF8304MTRPBF pinout, IRF8304MTRPBF application, or IRF8304MTRPBF equivalent, this part is selected for high-frequency DC-DC conversion where low conduction loss, fast switching, dual-sided cooling, and PCB footprint compatibility with MICRO-8 layouts are critical.
Technical Context
This MOSFET uses HEXFET® silicon in a copper-clip DirectFET® MX package enabling drain-source current flow through top and bottom metal surfaces - supporting dual-sided thermal management and reducing junction-to-ambient thermal resistance to 12.5°C/W (with heatsink). Its 1.8 V gate threshold and -6.1 mV/°C temperature coefficient ensure stable turn-on across industrial temperature range.
The device is characterized for synchronous rectification in 12 V input buck converters, with optimized Qgd/Qgs2 ratio (7.9 nC / 4.2 nC) and 420 pF Crss to minimize Miller-induced shoot-through risk and support >1 MHz switching without excessive gate drive loss.

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 |
|---|---|---|---|
| SiR872DP-T1-GE3 | RDS(on) = 1.8 mΩ @ 10 V; Qg = 31 nC; TSDSON8 package (0.9 mm height) | Higher profile limits dual-sided cooling; slightly higher switching loss at 1 MHz | Preferred when legacy SO-8 layout reuse is required and thermal budget allows +0.2 mm height |
| IPB80N04S4-02 | RDS(on) = 2.0 mΩ @ 10 V; Qg = 45 nC; TO-263 package (4.8 mm height) | Single-sided cooling only; 3.5× taller; higher gate drive power needed | Chosen where existing TO-263 heatsink infrastructure exists and board height is unconstrained |
Compared with SiR872DP-T1-GE3 and IPB80N04S4-02, the IRF8304MTRPBF delivers superior thermal performance per unit volume due to its 0.7 mm DirectFET® MX package and dual-sided current path - making it uniquely suited for ultra-thin, high-density server and AI hardware where vertical space and thermal resistance are limiting factors.

FAQ
What is the maximum continuous drain current at 70°C ambient temperature?
The IRF8304MTRPBF supports 190 A continuous drain current at TA = 70°C when mounted on a 1 in² copper board with dual-sided cooling and proper thermal interface. This rating assumes VGS = 10 V and accounts for derating due to increased RDS(on) at elevated temperature - verified per Figure 12 in the official datasheet.
Does this MOSFET require a negative gate voltage for safe turn-off in high-dv/dt environments?
No. The IRF8304MTRPBF has a gate threshold voltage of 1.8 V (typical) and is fully enhanced at 0 V gate-source bias. A negative gate voltage is not required; however, a gate resistor ≤25 Ω and local gate-source capacitor (≥10 nF) are recommended to suppress ringing during fast switching in high-noise power stages.
Can the top and bottom drain pads be used simultaneously for current sharing?
Yes - both top and bottom metal pads are electrically connected to the same internal drain node and designed for simultaneous conduction. The datasheet specifies dual-sided cooling capability and confirms identical RDS(on) contribution from both paths, enabling true parallel current distribution and halving effective thermal resistance compared to single-sided packages.
Is the IRF8304MTRPBF suitable for avalanche-rated operation?
Yes - it is rated for 800 mJ single-pulse avalanche energy (EAS) at IAS = 22 A, as shown in Figure 14. This capability supports unclamped inductive switching in synchronous rectifier applications where body diode commutation may occur, provided layout minimizes stray inductance and gate drive remains active during recovery.
