Product details
Overview
IRF1324SPBF from Infineon Technologies is a 24 V, 1.3 mΩ typ., 340 A silicon-limited N-channel HEXFET Power MOSFET in D2PAK (TO-263) package, optimized for high-current synchronous rectification and hard-switched SMPS topologies where low conduction loss and robust avalanche capability are critical.
For engineers reviewing the IRF1324SPBF datasheet, IRF1324SPBF pinout, IRF1324SPBF application, or IRF1324SPBF equivalent, key selection criteria include its 1.3 mΩ RDS(on) at VGS = 10 V, 195 A package-limited continuous current, 1420 A pulsed diode current, and validated unclamped inductive switching performance up to 195 A with 46 ns trr.
Technical Context
This MOSFET employs planar silicon process technology with enhanced body diode dV/dt and dI/dt ruggedness, enabling reliable operation in high-frequency, high-di/dt synchronous rectifier circuits. Its gate charge profile (Qg = 160–240 nC, Qgd = 49 nC) supports efficient gate drive design for <100 kHz hard-switched converters.
The device features thermally limited single-pulse avalanche energy of 1420 mJ at IAS = 195 A and is characterized for junction-to-case thermal resistance of 0.50 °C/W - critical for high-power board-level thermal management in UPS and server power supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 24 V - Maximum blocking voltage; defines use in ≤24 V DC bus systems like 12 V/24 V server VRMs and telecom rectifiers. |
| RDS(on) typ. | 1.3 mΩ @ VGS = 10 V, TJ = 25°C - Enables <0.5 W conduction loss at 195 A, reducing heatsink requirements in high-current paths. |
| ID (Silicon Limited) | 340 A @ TC = 25°C - Silicon die current capacity; actual usable current constrained by package and thermal design. |
| ID (Package Limited) | 195 A @ TC = 25°C - Wire-bond current limit; governs maximum continuous PCB-mount current without derating. |
| Qg | 160–240 nC - Total gate charge determines driver strength needed; impacts switching loss and gate drive loop stability. |
| trr | 46 ns @ TJ = 25°C - Body diode reverse recovery time; enables clean commutation in synchronous buck stages above 300 kHz. |
| EAS | 1420 mJ - Single-pulse avalanche energy rating; supports robustness against inductive switching transients in UPS and motor drives. |
Pinout & Package
IRF1324SPBF uses the surface-mount D2PAK (TO-263) package with exposed drain pad for thermal and electrical connection. The package has three terminals: Gate (G), Drain (D), and Source (S), arranged in standard G-D-S order on the lead frame.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| G | Gate control input | Receives 10 V logic-level drive; internal RG = 2.3 Ω affects turn-on/off timing and ringing susceptibility. |
| D | Drain (high-side switch node) | Connected to exposed copper pad; carries full load current and must be soldered to large thermal plane for RθJC = 0.50 °C/W. |
| S | Source (power return path) | Common reference for gate drive and current sensing; low-inductance layout essential for di/dt stability. |
Key Features
| Feature | Design Value |
|---|---|
| Enhanced body diode dV/dt and dI/dt capability | Validated for di/dt ≤ 450 A/µs and VDD ≤ V(BR)DSS, enabling stable operation in high-frequency synchronous rectification without snubbers. |
| Fully characterized SOA and avalanche ratings | Maximum Safe Operating Area defined up to 100 µs pulse width; EAS = 1420 mJ ensures reliability under unclamped inductive switching stress. |
| Low Coss eff. (TR) | 4490 pF - Effective output capacitance governing turn-off delay and capacitive losses during hard switching at 12–24 V. |
| Lead-free and RoHS-compliant construction | Meets IPC-J-STD-020 moisture sensitivity level 1; suitable for lead-free reflow profiles up to 260°C peak. |

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 |
|---|---|---|---|
| IRF1324LSPBF | Same die, TO-262 (IPAK) package; RθJC = 0.50 °C/W identical, but lower thermal mass and no exposed drain pad. | Limited to lower-power industrial controls due to reduced PCB thermal coupling and 175 A package current rating. | Select when through-hole mounting or legacy footprint compatibility is required; avoid for >150 A continuous designs. |
| STL220N4L10AG | 24 V, 0.95 mΩ typ., 220 A, DFN8 5×6 mm; lower RDS(on) but only 100 A continuous and no avalanche rating published. | Suitable for space-constrained consumer power banks but not for industrial UPS or server VRMs requiring proven avalanche robustness. | Prefer for compact, low-loss applications below 100 A; reject where unclamped inductive stress or >120 A continuous current is present. |
Compared with IRF1324LSPBF and STL220N4L10AG, IRF1324SPBF uniquely combines D2PAK thermal performance, 195 A package-limited current, and fully characterized 1420 mJ avalanche energy - making it the only option qualified for high-reliability, high-current synchronous rectification in mission-critical power systems.

FAQ
What is the maximum continuous drain current for IRF1324SPBF at 100°C case temperature?
The maximum continuous drain current for IRF1324SPBF at TC = 100°C is 240 A, as specified in the Absolute Maximum Ratings table. This value reflects silicon-limited conduction capability under thermal constraint, and assumes proper PCB copper area and airflow to maintain case temperature.
Does IRF1324SPBF support logic-level gate drive?
No - IRF1324SPBF requires VGS = 10 V for full RDS(on) specification (1.3 mΩ). Its gate threshold voltage range is 2.0–4.0 V, but conduction resistance rises sharply below 8 V; it is not rated for reliable operation with 3.3 V or 5 V logic-level drivers.
Can IRF1324SPBF be used in parallel configurations?
Yes - its positive RDS(on) temperature coefficient (see Fig. 4) ensures inherent current sharing when paralleled. Designers must match gate drive loop inductance and use Kelvin-source connections to prevent oscillation; typical layouts support up to four devices in parallel for >700 A systems.
Is the body diode of IRF1324SPBF suitable for reverse recovery in high-frequency operation?
Yes - with trr = 46 ns at 25°C and Qrr = 160 nC, the body diode is characterized for synchronous rectification up to 500 kHz. Performance degrades above 125°C (trr = 71 ns), so thermal design must keep TJ < 125°C for optimal high-frequency behavior.
