Product details
Overview
IRL2703SPBF from Infineon Technologies is a logic-level N-channel MOSFET designed for high-efficiency DC-DC conversion and load switching in 3.3 V/5 V gate-drive systems. It features 30 V VDS, 24 A continuous drain current (TC = 100 °C), 32 mΩ RDS(on) at VGS = 4.5 V, and D2PAK (TO-263) package. Used in synchronous buck converters and hot-swap circuits.
For engineers reviewing the IRL2703SPBF datasheet, IRL2703SPBF pinout, IRL2703SPBF application, or IRL2703SPBF equivalent, key selection criteria include RDS(on) at low gate voltage, SOA robustness under pulse loads, thermal resistance in surface-mount layout, and avalanche energy rating for inductive switching.
Technical Context
This MOSFET employs TrenchStop® technology to achieve low conduction loss and fast switching with minimal gate charge (Qg = 28 nC typ). Its threshold voltage (VGS(th) = 1.0–2.0 V) ensures full enhancement with standard logic-level drivers.
The device supports repetitive avalanche operation up to EAS = 110 mJ and exhibits 100% UIS-tested ruggedness. Thermal design leverages the D2PAK's low RthJC = 1.2 K/W for high-current PCB mounting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 30 V - Maximum blocking voltage in power-switching paths with ≤30 V rail margin. |
| ID (continuous, TC = 100 °C) | 24 A - Sustained current capability when mounted on 1-in² 2-oz copper with thermal vias. |
| RDS(on) @ VGS = 4.5 V | 32 mΩ max - Enables <1 W conduction loss at 15 A, critical for 5 V gate-drive efficiency. |
| Qg | 28 nC typ - Reduces driver power and switching transition time in high-frequency SMPS. |
| EAS | 110 mJ - Supports reliable operation during inductive turn-off transients without external snubbers. |
| RthJC | 1.2 K/W - Allows direct junction-to-heatsink thermal path in D2PAK footprint for compact thermal design. |
Pinout & Package
D2PAK (TO-263) package: surface-mount, isolated tab, 3-pin configuration with exposed drain pad for thermal and electrical connection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Source) | Return path for load current | Low-inductance source connection; ties directly to ground plane for EMI control. |
| Pin 2 (Gate) | Control input for channel conduction | High-impedance node requiring <100 Ω series resistor to suppress ringing in fast-switching layouts. |
| Pin 3 (Drain) | Main current-carrying terminal | Internally connected to exposed metal tab - must be electrically tied to high-side node or heatsink. |
Key Features
| Feature | Design Value |
|---|---|
| Logic-level gate drive compatibility | Full enhancement at VGS ≥ 4.5 V enables direct interface with microcontroller GPIOs and PWM controllers. |
| 100% avalanche tested | Guarantees single-pulse and repetitive avalanche survival without derating in flyback or buck-boost topologies. |
| Low gate charge (Qg) | 28 nC minimizes driver losses and allows >500 kHz switching in synchronous rectifiers. |
| Enhanced SOA at high TJ | Rated for 10 A @ 30 V at TJ = 125 °C - supports sustained linear-mode operation in hot-swap FETs. |
Applications
| DC-DC Synchronous Buck Converter | Hot-Swap Controller FET |
|---|---|

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 |
|---|---|---|---|
| STP30NF20 | 200 V VDS, 30 A ID, higher RDS(on) (40 mΩ @ 10 V), requires 10 V gate drive | Suitable for higher-voltage industrial motor drives but not logic-level 3.3 V systems | Select only if system uses 10 V gate bias and needs >100 V breakdown margin. |
| IRFZ44NPBF | 55 V VDS, 49 A ID, RDS(on) = 28 mΩ @ 10 V, not logic-level (VGS(th) = 2–4 V) | Better for 12 V gate-driven half-bridges; marginal at 4.5 V due to higher threshold spread | Prefer for 12 V gate designs where higher voltage headroom is required over logic compatibility. |
Compared with STP30NF20 and IRFZ44NPBF, IRL2703SPBF uniquely delivers 32 mΩ RDS(on) at 4.5 V with guaranteed 1.0–2.0 V VGS(th), making it the only choice among the three for robust 3.3 V microcontroller-driven switching below 30 V.

FAQ
What is the maximum pulsed drain current (IDM) for IRL2703SPBF?
The IRL2703SPBF has a rated pulsed drain current of 96 A (tp ≤ 10 µs, duty cycle ≤ 1%). This value is derived from its Safe Operating Area (SOA) curve at TC = 25 °C and reflects short-duration surge capability during inductive turn-off or motor stall events.
Does IRL2703SPBF require a gate resistor in typical switching applications?
Yes - a 10–47 Ω gate series resistor is recommended to dampen gate-source ringing and limit peak gate current. The device's Qg of 28 nC and low Ciss make it susceptible to oscillation without proper gate control, especially when driven by high-speed PWM controllers.
Can IRL2703SPBF be used in parallel configurations?
Yes - its positive temperature coefficient of RDS(on) enables stable current sharing. Parallel operation requires matched gate drive impedance, symmetrical PCB layout, and shared thermal mass. Derating to 80% of total rated current per device is advised for reliability.
Is the D2PAK drain tab electrically isolated from the PCB mounting surface?
No - the D2PAK drain tab is internally connected to Pin 3 (Drain) and is not electrically isolated. When mounted on a heatsink or copper pour, that surface must be at drain potential unless insulated with a dielectric pad or thermal tape rated for ≥30 V working voltage.
