Product details
Overview
IRL3803STRRPBF from Infineon Technologies is a 30 V, 140 A, 3.3 mΩ N-channel HEXFET Power MOSFET in TO-263 (D²Pak) package, optimized for high-efficiency DC-DC conversion and motor control in industrial power supplies and battery-powered tools.
For engineers reviewing the IRL3803STRRPBF datasheet, IRL3803STRRPBF pinout, IRL3803STRRPBF application, or IRL3803STRRPBF equivalent, key selection criteria include RDS(on) at 10 V gate drive, continuous drain current rating, thermal resistance (RθJC), and logic-level gate threshold compatibility with 3.3 V/5 V microcontrollers.
Technical Context
This MOSFET employs Trench technology to achieve low on-resistance and fast switching with minimal gate charge (Qg = 80 nC typical). It features avalanche-rated operation and enhanced body diode recovery performance for synchronous rectification and H-bridge configurations.
The device supports logic-level gate drive (VGS(th) = 1.0–2.0 V), enabling direct interface with standard CMOS outputs without level-shifting circuitry, and exhibits low reverse recovery charge (Qrr = 190 nC) for reduced switching losses in hard-switched topologies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 30 V - Maximum drain-source blocking voltage for 12 V and 24 V system rails |
| RDS(on) @ VGS = 10 V | 3.3 mΩ - Enables <1 W conduction loss at 140 A, critical for high-current POL converters |
| ID (continuous) | 140 A - Supports high-power motor drives and server VRMs without parallel devices |
| Qg | 80 nC - Reduces gate driver power demand and enables >500 kHz switching in SMPS designs |
| RθJC | 0.7°C/W - Allows 100+ W power dissipation with moderate heatsinking in TO-263 package |
| VGS(th) | 1.0–2.0 V - Ensures full enhancement with 3.3 V GPIO, eliminating external level shifters |
Pinout & Package
Package: TO-263 (D²Pak), surface-mount, single-ended heat sink tab (drain-connected).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Tab (exposed pad) | Drain | Primary current path and thermal interface; must be soldered to PCB copper pour for thermal management |
| Lead 1 | Source | Reference node for gate drive and current sensing; connects to power ground plane |
| Lead 2 | Gate | Control input requiring <80 nC charge; sensitive to ESD and layout-induced ringing |
| Lead 3 | Source | Second source connection for low-inductance return path in high-di/dt applications |
Key Features
| Feature | Design Value |
|---|---|
| Logic-level gate drive | Operates fully enhanced at 3.3 V, enabling direct MCU interface without gate driver ICs |
| Avalanche rated | Specified UIS energy of 330 mJ ensures robustness against inductive switching transients |
| Low Qrr body diode | 190 nC reverse recovery charge minimizes shoot-through risk and loss in synchronous buck stages |
| Trench process technology | Delivers 3.3 mΩ RDS(on) in TO-263, reducing footprint vs. older planar MOSFETs at same current rating |
Applications
| Industrial Motor Drives | Server Point-of-Load Converters |
|---|---|
Use Scenario: 24 V BLDC motor control in CNC spindles and automated machinery. IC Role / Device Role / Timing Role: Low-side switch in three-phase inverter leg, handling peak currents up to 140 A. Use Value: 3.3 mΩ RDS(on) limits conduction loss to <0.7 W at 120 A, improving thermal margin and efficiency. | Use Scenario: High-current step-down regulator supplying CPU core voltage in rack-mounted servers. IC Role / Device Role / Timing Role: Synchronous rectifier in 300–600 A multiphase buck converter. Use Value: Low Qg (80 nC) and Qrr (190 nC) reduce gate drive loss and body diode loss during dead-time transitions. |
| Battery-Powered Power Tools | Telecom DC-DC Modules |
Use Scenario: High-torque drill/driver with 18–40 V Li-ion pack and electronic torque limiting. IC Role / Device Role / Timing Role: Main power switch in PWM-controlled H-bridge for bidirectional motor control. Use Value: Avalanche rating (330 mJ) withstands inductive kickback during abrupt current interruption under stall conditions. | Use Scenario: 48 V to 12 V intermediate bus converter in telecom shelf power systems. IC Role / Device Role / Timing Role: Primary-side switch in phase-shifted full-bridge topology operating at 200–300 kHz. Use Value: RθJC = 0.7°C/W allows 85 W continuous dissipation with 40°C temperature rise, supporting compact module design. |
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 |
|---|---|---|---|
| IRL3803PBF | Same die, TO-220 package; RθJC = 1.0°C/W; lower max ID (110 A) | Limited to lower-power motor drives and adapters where through-hole mounting is required | Select when board space permits TO-220 and thermal budget allows higher junction rise |
| IPB033N03L | 30 V, 160 A, 3.3 mΩ, but requires 4.5 V min VGS; Qg = 67 nC | Better suited for 5 V gate drive systems; slightly faster switching but not logic-level compatible | Choose when using 5 V microcontrollers or dedicated gate drivers, prioritizing lower Qg |
Compared with IRL3803PBF, the STRRPBF offers superior thermal performance and higher current capability in surface-mount form; versus IPB033N03L, it provides guaranteed 3.3 V logic-level turn-on at the cost of slightly higher Qg, making it optimal for embedded MCU-driven systems.

FAQ
Is IRL3803STRRPBF RoHS-compliant and lead-free?
Yes, IRL3803STRRPBF is RoHS-compliant and lead-free per EU Directive 2011/65/EU. The "PbF" suffix confirms lead-free termination, and the device meets JEDEC J-STD-020 moisture sensitivity level 3 (MSL3) requirements for surface-mount assembly.
What is the maximum safe operating temperature for continuous operation?
The maximum junction temperature is 175°C. With RθJC = 0.7°C/W and a 40°C ambient, sustained 140 A operation requires a heatsink or PCB copper area capable of maintaining case temperature ≤105°C to stay within thermal limits.
Can IRL3803STRRPBF replace IRL3803PBF in an existing TO-220 layout?
No - IRL3803STRRPBF uses TO-263 (D²Pak) packaging with different footprint, thermal pad layout, and lead spacing. Direct replacement requires PCB redesign to accommodate the surface-mount outline and exposed drain tab soldering requirements.
Does this MOSFET require a gate resistor for stability in high-frequency switching?
Yes - a 5–10 Ω gate series resistor is recommended to dampen parasitic oscillation caused by PCB trace inductance interacting with Ciss (2800 pF) and Qg, especially above 200 kHz. Layout optimization (short gate traces, ground plane under gate loop) remains critical.
