Product details
Overview
IRLU8113PBF from Infineon Technologies is a 30V, 12A N-channel HEXFET Power MOSFET in D-Pak package, optimized for high-frequency synchronous buck converters in CPU power delivery and telecom DC-DC applications. It features 4.8 mΩ RDS(on) at VGS = 10 V, 22 nC total gate charge, and fully characterized avalanche capability (EAS = 700 mJ).
For engineers reviewing the IRLU8113PBF datasheet, IRLU8113PBF pinout, IRLU8113PBF application, or IRLU8113PBF equivalent, key selection criteria include low RDS(on) at 4.5 V drive, ultra-low gate impedance for fast switching, and robust unclamped inductive switching performance in high-efficiency power stages.
Technical Context
This MOSFET employs planar vertical HEXFET architecture with optimized cell pitch and trench-free die design to achieve low on-resistance and high dV/dt immunity. Its gate threshold voltage (1.35–2.25 V) and negative temperature coefficient of VGS(th) (−5.6 mV/°C) support stable parallel operation in multi-phase VRMs.
The device integrates an intrinsic body diode with 33–49 ns reverse recovery time and 30–45 nC Qrr, enabling efficient synchronous rectification without external Schottky diodes. Thermal resistance RθJC is 1.69 °C/W, confirming suitability for PCB-mounted thermal management in compact power modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 30 V - supports 24 V input rails with 25 % margin against transients in telecom and industrial DC-DC systems |
| RDS(on) max @ 10 V | 6.0 mΩ - enables <1.5 W conduction loss at 12 A continuous drain current in 100 °C ambient designs |
| Qg | 22 nC - minimizes gate drive power and allows use with low-current PWM controllers (e.g., ISL62xx series) |
| EAS | 700 mJ - sustains single-pulse inductive energy without failure in synchronous buck high-side switching |
| Ciss | 2920 pF - determines Miller capacitance impact on turn-on delay and gate driver sizing at >500 kHz switching |
| Qrr | 30–45 nC - directly contributes to cross-conduction losses in synchronous FETs and affects shoot-through risk |
| RθJC | 1.69 °C/W - enables direct heatsink mounting via screw (6-32/M3) for thermal derating down to 0.59 W/°C above 100 °C |
Pinout & Package
IRLU8113PBF uses the industry-standard D-Pak (TO-252AA) surface-mount package with exposed drain pad for thermal and electrical connection. The package measures 6.73 × 6.22 × 2.39 mm and is lead-free and RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (G) | Gate | High-impedance control terminal requiring ≤2.25 V threshold; sensitive to ESD and Cdv/dt coupling in synchronous node placement |
| Pin 2 (D) | Drain | Connected to exposed copper pad; carries full load current and serves as primary thermal path to PCB heatsink |
| Pin 3 (S) | Source | Reference node for gate drive; must be low-inductance routed to minimize VGS noise during switching transitions |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low RDS(on) at 4.5 V | 7.4 mΩ max - enables direct drive from 5 V logic or low-voltage PWM controllers without level-shifting |
| Low gate charge (Qgd) | 6.8 nC - reduces Miller-induced turn-on risk and improves hard-switching efficiency above 1 MHz |
| Characterized avalanche rating | EAS = 700 mJ - eliminates need for external snubbers in clamped inductive loads like VRM output chokes |
| Body diode Qrr specification | 30–45 nC - allows accurate loss modeling for synchronous rectifier timing and dead-time optimization |
| Thermal derating linearity | 0.59 W/°C above 100 °C - supports predictable power derating in sealed industrial enclosures |
Applications

Use Value: 22 nC Qg and 6.8 nC Qgd enable clean turn-off under high dV/dt, reducing cross-conduction losses by 22 % versus higher-Qgd alternatives. |
| Industrial PLC Power Module | Automotive ADAS Domain Controller |
Use Scenario: Compact 24 V input buck regulator powering FPGA, ADCs, and isolated communication interfaces in harsh environments. IC Role / Device Role / Timing Role: Primary switch in non-isolated point-of-load regulator with extended temperature operation (−40 to +125 °C).

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 |
|---|---|---|---|
| IRLR8113PbF | I-Pak package (TO-251), identical die and electrical specs, RθJA = 110 °C/W vs. 50 °C/W for D-Pak | Better suited for through-hole prototyping or low-volume manual assembly; lower thermal performance in SMT production | Select when mechanical mounting constraints require leaded package or when board-level rework is prioritized over thermal density |
| SI7850DP-T1-GE3 | 30 V, 14 A, RDS(on) = 4.5 mΩ @ 10 V, Qg = 26 nC, SO-8 package with dual-source capability | Higher gate charge increases driver loss; SO-8 limits current handling and thermal dissipation vs. D-Pak | Prefer for space-constrained layouts where footprint size outweighs thermal performance, e.g., consumer-grade PoL modules |
Compared with IRLR8113PbF, the IRLU8113PBF offers superior thermal performance in automated SMT lines due to its D-Pak thermal pad; versus SI7850DP-T1-GE3, it delivers lower switching loss at high frequency despite slightly higher Qg, making it more suitable for telecom and server VRMs demanding >95 % efficiency.

FAQ
What is the maximum continuous drain current at 100 °C case temperature?
The IRLU8113PBF supports 30 A continuous drain current at TC = 25 °C and derates linearly to 13 A at TC = 100 °C, based on its 0.59 W/°C thermal derating factor and 1.69 °C/W junction-to-case resistance. This value assumes proper PCB copper area and thermal via implementation per IR's layout guidelines.
Does this MOSFET require a gate resistor for stability in synchronous buck topologies?
Yes - a 2.2–4.7 Ω gate resistor is recommended between driver output and gate pin to dampen ringing caused by Lg–Ciss resonance and suppress Cdv/dt-induced turn-on. The low Qgd/Qgs1 ratio (6.8/6.1 ≈ 1.1) makes it less prone to false triggering than older MOSFETs, but external damping remains essential in >500 kHz designs.
Can the body diode be used for freewheeling in non-synchronous configurations?
Yes - the integrated body diode has VSD ≤ 1.0 V at 12 A and trr = 33–49 ns, making it viable for low-frequency (<100 kHz), low-duty-cycle freewheeling. However, its Qrr (30–45 nC) causes significant reverse recovery loss at high frequency, so synchronous rectification is strongly preferred above 250 kHz.
Is there a recommended PCB footprint for optimal thermal performance?
Infineon specifies a minimum 120 mm² exposed drain pad with ≥8 thermal vias (0.3 mm diameter, 0.8 mm pitch) connecting to inner ground/power planes. The recommended land pattern matches IPC-7351B SO-252 (D-Pak) standard, with solder mask defined pads to maximize copper exposure and minimize thermal resistance to ambient.
