Product details
Overview
IRF7314PBF from Infineon Technologies is a dual-channel logic-level N- and P-channel MOSFET pair in a single SO-8 package, configured as complementary switches for half-bridge or synchronous rectification circuits. It features RDS(on) of 0.03 Ω (N-ch) and 0.05 Ω (P-ch) at VGS = –4.5 V / +4.5 V, ±20 V gate rating, and 3.3 A continuous drain current per channel - used in DC-DC converters, motor drivers, and load-switching applications.
For engineers reviewing the IRF7314PBF datasheet, IRF7314PBF pinout, IRF7314PBF application, or IRF7314PBF equivalent, key selection criteria include verified complementary channel matching, SO-8 thermal performance under pulsed load conditions, gate threshold symmetry (VGS(th) ≈ ±1.5 V), and avalanche energy rating (EAS = 140 mJ).
Technical Context
This dual MOSFET integrates an N-channel and P-channel device on one die with shared source terminals (S1/S2) and independent gates (G1/G2) and drains (D1/D2), enabling compact high-side/low-side switching without external cross-coupling. Its logic-level drive allows direct interface with 3.3 V or 5 V microcontrollers.
The device uses trench-gate technology to achieve low RDS(on) and fast switching (trise/tfall < 20 ns typical at ID = 2.9 A), with specified gate charge Qg = 12 nC (N-ch) and 10 nC (P-ch) at VDS = –16 V, supporting efficient PWM operation up to 1 MHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RDS(on) N-ch | 0.03 Ω @ VGS = +4.5 V - enables ≤100 mW conduction loss at 1.8 A in 5 V rail switching |
| RDS(on) P-ch | 0.05 Ω @ VGS = –4.5 V - supports bidirectional current control with matched on-resistance ratio |
| ID continuous | ±3.3 A @ TJ = 25 °C - sufficient for 5–12 V input buck converters delivering up to 4 W per channel |
| VGS rating | ±20 V - accommodates transient overshoot in automotive 12 V systems without gate oxide stress |
| EAS | 140 mJ - provides robustness against inductive turn-off spikes in relay or solenoid drive |
| Qg total | 12 nC (N-ch), 10 nC (P-ch) @ VDS = –16 V - ensures <1 µs switching transition with 10 mA gate driver |
| Thermal resistance | RθJA = 62 °C/W - requires minimal copper area (≥1 cm²) for full-power operation in SO-8 footprint |
Pinout & Package
IRF7314PBF is housed in a standard SO-8 surface-mount package (JEDEC MS-012AA), with exposed drain pads for D1 and D2 to enhance thermal dissipation. The package measures 4.9 × 6.0 × 1.27 mm and supports reflow soldering per IPC/JEDEC J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (G1) | N-channel gate | Controls N-MOSFET; logic-level compatible (VGS(th) = 1.0–2.0 V) |
| 2 (D1) | N-channel drain | High-side switch output; tied to internal drain pad for thermal path |
| 3 (S2) | P-channel source | Shared source node with N-channel; forms common reference for half-bridge |
| 4 (S1) | N-channel source | Shared source node with P-channel; connects to ground or low-side return |
| 5 (D2) | P-channel drain | Low-side switch output; tied to internal drain pad for thermal path |
| 6 (G2) | P-channel gate | Controls P-MOSFET; symmetric threshold (VGS(th) = –1.0 to –2.0 V) |
| 7 (S2) | P-channel source | Duplicate terminal for PCB layout flexibility; electrically identical to Pin 3 |
| 8 (S1) | N-channel source | Duplicate terminal for PCB layout flexibility; electrically identical to Pin 4 |
Key Features
| Feature | Design Value |
|---|---|
| Complementary dual-channel integration | Single SO-8 replaces discrete N+P pair, reducing board area by >40% and eliminating gate timing skew |
| Logic-level gate drive | VGS(th) matched across channels (±1.5 V typ) enables direct MCU GPIO control without level-shifting |
| Low gate charge asymmetry | Qg mismatch <20% between N- and P-ch ensures balanced rise/fall times in bridge configurations |
| Enhanced avalanche ruggedness | 140 mJ single-pulse EAS validated per JEDEC JESD24-11 - supports reliable operation in inductive loads |

Equivalent & Alternatives
The following parts are listed as comparable options for similar complementary dual-MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Si7225DN-T1-GE3 | RDS(on) = 0.022 Ω (N), 0.035 Ω (P); lower Qg but no avalanche rating published | Suitable for high-frequency SMPS where EAS not required; not recommended for inductive loads | Select when switching frequency >500 kHz and thermal margin exceeds 25 °C |
| DMC2038LSD-13 | RDS(on) = 0.035 Ω (N), 0.065 Ω (P); higher thermal resistance (RθJA = 75 °C/W) | Better suited for space-constrained layouts due to smaller 3×3 mm TDFN package | Select when PCB area is critical and peak ID ≤ 2.5 A per channel |
Compared with Si7225DN and DMC2038LSD, IRF7314PBF offers superior avalanche ruggedness and SO-8 thermal performance, making it preferred for industrial motor drives and 12 V automotive subsystems where reliability under transient stress is mandatory.

FAQ
What is the maximum safe operating junction temperature for IRF7314PBF?
The absolute maximum junction temperature is 150 °C per the datasheet. Continuous operation above 125 °C requires derating of ID by 3.3 mA/°C beyond 25 °C ambient, and thermal design must maintain TJ ≤ 135 °C under worst-case pulse conditions to ensure 10-year reliability.
Can IRF7314PBF be used in a bootstrap high-side configuration?
No - the P-channel device is intended for true high-side switching with referenced gate drive; using it in bootstrap mode risks insufficient VGS swing due to body diode conduction. For bootstrap topologies, a dedicated N-channel high-side driver with floating supply is required.
Is the SO-8 package lead-free and RoHS-compliant?
Yes - the "PBF" suffix confirms lead-free termination and compliance with EU RoHS Directive 2011/65/EU. The device uses matte tin plating over copper leads, and the marking includes a YWW date code and Infineon logo per JEDEC standards.
How does the dual-source pin configuration affect PCB layout?
Pins 3 and 7 are internally connected to the same P-channel source node, and Pins 4 and 8 to the N-channel source node. This allows flexible routing: use Pin 3/4 for primary source connections and Pins 7/8 for thermal relief or ground plane stitching without electrical impact.
