Product details
Overview
IRF7304QTRPBF from Infineon Technologies (formerly International Rectifier) is a dual P-channel enhancement-mode MOSFET in SO-8 package, designed for high-efficiency synchronous buck converters and load switching. It features RDS(on) = 35 mΩ @ VGS = −4.5 V per channel, −3.6 A continuous drain current, 150°C junction temperature rating, and integrated body diodes with low reverse recovery charge (Qrr = 12 nC). It is used in notebook CPU core power stages.
For engineers reviewing the IRF7304QTRPBF datasheet, IRF7304QTRPBF pinout, IRF7304QTRPBF application, or IRF7304QTRPBF equivalent, key selection criteria include dual-channel P-MOSFET matching, low gate charge (Qg = 19 nC), fast switching (tf = 12 ns), thermal performance in compact SO-8, and lead-free compliance for industrial power management designs.
Technical Context
This device implements two matched P-channel HEXFET® power MOSFETs on a single die within an SO-8 thermally enhanced surface-mount package. Each channel supports −3.6 A continuous drain current at TC = 25°C and exhibits RDS(on) ≤ 35 mΩ at VGS = −4.5 V and ≤ 48 mΩ at VGS = −2.5 V.
It delivers fast switching with total gate charge Qg = 19 nC, gate-to-source charge Qgs = 4.5 nC, and gate-to-drain charge Qgd = 7.5 nC at VDS = −16 V. The body diode has reverse recovery time trr = 45 ns and reverse recovery charge Qrr = 12 nC under specified test conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RDS(on) max | 35 mΩ @ VGS = −4.5 V - enables low conduction loss in high-current DC-DC stages |
| ID continuous | −3.6 A per channel - supports mid-power synchronous rectification without external heatsinking |
| Qg | 19 nC - reduces gate drive power and enables efficient operation at 500 kHz–1 MHz switching frequencies |
| tf | 12 ns - minimizes switching transition losses during turn-off in buck topologies |
| TJ max | 150°C - ensures reliable operation under sustained thermal stress in enclosed laptop power modules |
| Qrr | 12 nC - lowers body-diode conduction loss and EMI during dead-time in synchronous converters |
Pinout & Package
IRF7304QTRPBF is housed in a standard SO-8 (JEDEC MS-012AA) surface-mount package with exposed drain pads for improved thermal dissipation. Pin 1 is Gate 1 (G1), Pin 2 is Source 1 (S1), Pin 3 is Drain 1 (D1), Pin 4 is Drain 2 (D2), Pin 5 is Source 2 (S2), Pin 6 is Gate 2 (G2), Pin 7 is not connected (NC), Pin 8 is common drain (D1/D2 tie).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| G1 | Gate of Channel 1 | Controls turn-on/turn-off of first P-MOSFET; requires negative gate drive relative to source |
| S1 | Source of Channel 1 | Reference node for G1; tied to output rail in high-side switch configuration |
| D1 | Drain of Channel 1 | Connects to input voltage rail; shares internal metal trace with D2 and Pin 4 |
| D2 | Drain of Channel 2 | Electrically tied to D1 internally; provides parallel current path and thermal sharing |
| S2 | Source of Channel 2 | Reference node for G2; independently routed for dual-phase control |
| G2 | Gate of Channel 2 | Independent control input enabling phase-split or paralleled operation |
| Pin 7 | No Connect | Internally isolated; must remain unconnected per design to avoid parasitic coupling |
| Pin 8 | Common Drain Pad | Exposed copper pad beneath package bottom; soldered to PCB ground plane for thermal and electrical return |
Key Features
| Feature | Design Value |
|---|---|
| Dual matched P-channel MOSFETs | Ensures balanced current sharing and timing in synchronous buck high-side/low-side pairs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual P-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Si7851DP-T1-GE3 | RDS(on) = 28 mΩ @ −4.5 V; Qg = 22 nC; SO-8 with enhanced thermal pad | Lower on-resistance but higher gate charge - better for static efficiency, worse for high-frequency switching | Prefer when conduction loss dominates over switching loss (e.g., <300 kHz operation) |
| DMC3025LSD-13 | RDS(on) = 30 mΩ @ −4.5 V; Qg = 16 nC; dual P-ch in PowerSO-8 with 2× thermal pad area | Superior thermal resistance (θJA = 48°C/W); no NC pin - tighter layout but less routing flexibility | Prefer when board space is constrained and thermal margin is critical (e.g., sealed enclosures) |
Compared with IRF7304QTRPBF, Si7851DP offers lower conduction loss but higher gate drive demand, while DMC3025LSD delivers better thermal performance and smaller footprint at the cost of reduced pinout flexibility for gate routing.

FAQ
What is the maximum safe operating voltage for IRF7304QTRPBF?
The absolute maximum VDS rating is −30 V. Operation beyond this value risks avalanche breakdown and permanent damage. Derating to −24 V is recommended for reliability in 12 V input systems with transient spikes. The device is not rated for 48 V bus applications without external clamping.
Can IRF7304QTRPBF be used in a single-channel configuration?
Yes - either channel can be used independently by connecting its gate and source appropriately while leaving the unused gate floating (not recommended) or tied to source via 10 kΩ resistor. The drains are internally tied, so both channels share the same drain node and cannot operate at different potentials.
Is IRF7304QTRPBF suitable for linear regulator applications?
No - it is optimized for switching operation. Its RDS(on) increases significantly above 125°C, and power dissipation in linear mode exceeds SO-8 thermal limits even at 1 A. Use dedicated LDOs or bipolar pass transistors for linear regulation.
Does IRF7304QTRPBF require gate resistors in typical buck converter layouts?
Yes - a 5–10 Ω series gate resistor is recommended to damp ringing caused by PCB trace inductance and MOSFET input capacitance. This improves EMI performance and prevents false triggering due to dv/dt coupling, especially when driving at >500 kHz.
