Product details
Overview
IRLR4132TRPBF from Infineon Technologies is a surface-mount N-channel enhancement-mode MOSFET optimized for high-current DC-DC converter primary-side switching, featuring 30 V VDS, 160 A ID (TC = 100 °C), 2.8 mΩ RDS(on) at VGS = 10 V, and DPAK (TO-252) package. It delivers low conduction loss in synchronous buck converters for server VRMs and telecom power supplies.
For engineers reviewing the IRLR4132TRPBF datasheet, IRLR4132TRPBF pinout, IRLR4132TRPBF application, or IRLR4132TRPBF equivalent, key selection criteria include RDS(on) vs. gate charge trade-off, SOA compliance under repetitive avalanche conditions, thermal resistance (RθJC = 1.2 K/W), and gate threshold voltage stability across temperature.
Technical Context
This MOSFET employs Infineon's HEXFET® Trench technology to achieve ultra-low on-resistance with fast switching speed (trise = 25 ns, tfall = 20 ns at RG = 2.5 Ω). Its 100% UIS-rated avalanche capability supports robust operation in hard-switched topologies without external snubbers.
The device uses a standard three-terminal configuration with source-connected substrate, enabling straightforward gate drive design using ±20 V rated drivers. Its low Qg (71 nC) and Qgd (29 nC) reduce driver power loss and improve efficiency in high-frequency (>500 kHz) applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 30 V - Maximum drain-source blocking voltage for 12 V input bus designs with margin |
| RDS(on) @ VGS = 10 V | 2.8 mΩ - Enables <1.5 W conduction loss at 160 A continuous current (TC = 100 °C) |
| ID (continuous, TC = 100 °C) | 160 A - Supports high-current single-phase VRM stages up to 200 W output |
| Qg | 71 nC - Determines minimum gate driver peak current requirement (~1.4 A at 50 ns rise time) |
| RθJC | 1.2 K/W - Requires ≥25 cm² 2-oz copper pad for thermal compliance at full load |
| UIS Rating | 100% - Qualified per JEDEC JESD24-11; no derating needed for inductive turn-off stress |
Pinout & Package
DPAK (TO-252) thermally enhanced surface-mount package with exposed drain pad for direct PCB thermal coupling. Standard 3-pin layout: Pin 1 = Gate, Pin 2 = Drain (tab), Pin 3 = Source.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Gate (Pin 1) | Control terminal | Receives PWM signal; requires 10 V min for full enhancement; max VGS = ±20 V |
| Drain (Pin 2 / Tab) | High-side switch node | Electrically connected to exposed copper pad; must be routed to high-current path with thermal via array |
| Source (Pin 3) | Reference node | Connected to power ground plane; serves as return path for gate drive loop and sense reference |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low RDS(on) | 2.8 mΩ enables >95% efficiency in 12 V → 1 V/160 A VRM stage at 500 kHz |
| 100% Avalanche Rated | Eliminates need for external clamping diodes in hard-switched synchronous rectifiers |
| Low Gate Charge (Qg) | 71 nC reduces gate driver power dissipation by ~30% vs. comparable 3.5 mΩ MOSFETs |
| Thermally Optimized DPAK | Exposed drain pad lowers junction-to-case thermal resistance to 1.2 K/W for compact heatsinking |
Applications
| Server Voltage Regulator Modules | Telecom DC-DC Converters |

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 |
|---|---|---|---|
| IRLR3110ZPBF | RDS(on) = 4.5 mΩ (higher conduction loss); Qg = 52 nC (lower drive loss) | Better suited for lower-current (<100 A), higher-frequency (>1 MHz) applications | Select when gate drive power budget is tighter than conduction loss budget |
| STL220N3LLH6 | RDS(on) = 2.3 mΩ (lower loss); 5× larger Qg (350 nC); DFN5x6 package | Requires more complex gate driving and thermal management due to higher capacitance | Prefer for space-constrained designs where board area outweighs driver complexity |
Compared with IRLR3110ZPBF and STL220N3LLH6, the IRLR4132TRPBF balances conduction efficiency, gate drive simplicity, and thermal performance for 100–160 A industrial and telecom power stages-making it optimal where RDS(on) and Qg must both be minimized without sacrificing ruggedness.

FAQ
What is the maximum safe operating temperature for IRLR4132TRPBF?
The junction temperature must not exceed 175 °C. At TC = 100 °C, the device sustains 160 A continuous drain current. Thermal design must ensure RθJA ≤ 2.5 K/W with ≥25 cm² 2-oz copper and ≥6 thermal vias under the drain pad to maintain safe operation at full load.
Does IRLR4132TRPBF support logic-level gate drive?
No-it is not a logic-level MOSFET. Its typical VGS(th) is 1.6 V, but full enhancement requires VGS ≥ 10 V to achieve rated RDS(on) of 2.8 mΩ. Driving with 5 V will result in RDS(on) > 10 mΩ and excessive conduction loss; a dedicated 10–12 V gate driver is required.
Can IRLR4132TRPBF replace IRLR3110ZPBF in existing designs?
Yes, with verification of thermal and gate drive margins. The IRLR4132TRPBF offers 38% lower RDS(on) but 37% higher Qg. Layout must accommodate increased gate drive current, and thermal pads should be enlarged to handle higher power density, especially above 120 A.
Is IRLR4132TRPBF RoHS and REACH compliant?
Yes-IRLR4132TRPBF is RoHS-compliant (2011/65/EU) and REACH-conformant (SVHC-free per latest declaration). It is also halogen-free and qualified to AEC-Q101 for stress testing, though not officially automotive-qualified due to packaging limitations in extended temperature cycling.
