Product details
Overview
IRL540NSTRRPBF from Infineon Technologies is a 100 V, 36 A, N-channel enhancement-mode MOSFET in D2PAK (TO-263) package, featuring 44 mΩ RDS(on) at VGS = 10 V and 55 mΩ at 4.5 V, optimized for DC-DC converters and motor control switching applications.
For engineers reviewing the IRL540NSTRRPBF datasheet, IRL540NSTRRPBF pinout, IRL540NSTRRPBF application, or IRL540NSTRRPBF equivalent, key selection criteria include low gate charge (Qg = 71 nC), fast turn-on/turn-off times (ton = 25 ns, toff = 55 ns), and lead-free D2PAK thermal performance under continuous 36 A conduction.
Technical Context
This MOSFET uses planar stripe silicon technology with optimized cell pitch and trench-assisted channel geometry to achieve low RDS(on) while maintaining robust avalanche energy rating (EAS = 280 mJ). Its logic-level gate threshold (VGS(th) = 1.0–2.0 V) enables direct drive from 3.3 V and 5 V microcontrollers without gate drivers.
The device integrates a monolithic body diode with soft recovery characteristics (trr = 120 ns, Qrr = 190 nC), reducing voltage overshoot and EMI in hard-switched topologies such as synchronous buck converters and H-bridge motor drives.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 100 V - supports 48 V bus systems with 2× safety margin against transients |
| ID (continuous) | 36 A @ TC = 25°C - delivers full rated current with standard heatsinking on PCB |
| RDS(on) @ 10 V | 44 mΩ - limits conduction loss to ≤1.6 W at 6 A RMS in 12 V load switch |
| RDS(on) @ 4.5 V | 55 mΩ - ensures usable switching in 3.3 V logic-driven half-bridge configurations |
| Qg | 71 nC - determines gate driver power requirement (~0.36 mW average at 100 kHz) |
| EAS | 280 mJ - withstands single-pulse inductive kickback in 24 V solenoid drivers |
| trr | 120 ns - suppresses voltage spikes during freewheeling in buck regulators |
Pinout & Package
D2PAK (TO-263) surface-mount package with exposed drain pad for enhanced thermal dissipation; 3-pin configuration (G, D, S) with drain connected to backside metal tab.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| G (Gate) | Control electrode | Accepts 0–10 V logic signal; requires ≤71 nC charge for full enhancement |
| D (Drain) | High-side current output | Internally bonded to copper tab; must be thermally anchored to PCB ground plane |
| S (Source) | Reference node / return path | Provides low-impedance return for load current; ties to controller ground reference |
Key Features
| Feature | Design Value |
|---|---|
| Logic-level gate drive | Operates fully enhanced at 4.5 V VGS, eliminating need for level-shifting in 5 V MCU systems |
| Low RDS(on) at 4.5 V | 55 mΩ enables <1 W conduction loss in 12 V, 4 A load switches without forced air cooling |
| Fast switching speed | 25 ns ton/55 ns toff supports >200 kHz PWM in isolated DC-DC designs |
| Robust body diode | 190 nC Qrr and soft recovery reduce snubber component count in flyback 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 |
|---|---|---|---|
| IRF540NPBF | RDS(on) = 44 mΩ @ 10 V but VGS(th) = 2–4 V; not logic-level capable at 4.5 V | Requires 10 V gate drive; unsuitable for 3.3 V MCU direct drive | Choose only if system uses 12 V gate driver and prioritizes cost over drive simplicity |
| STP36NF10 | RDS(on) = 36 mΩ @ 10 V but Qg = 95 nC; higher switching loss at >100 kHz | Better conduction loss but slower switching; less efficient in high-frequency SMPS | Select when thermal budget allows larger heatsink and switching frequency ≤50 kHz |
Compared with IRF540NPBF and STP36NF10, IRL540NSTRRPBF uniquely balances logic-level drive compatibility, mid-frequency switching efficiency, and D2PAK thermal capability-making it optimal for space-constrained 3.3/5 V-controlled industrial power stages.

FAQ
What is the maximum junction temperature for reliable operation of IRL540NSTRRPBF?
The absolute maximum junction temperature is 175°C per the official Infineon datasheet PD-95234. Derating begins at 125°C ambient; sustained operation above 150°C junction requires active cooling and thermal vias under the D2PAK drain pad to maintain reliability over 10-year field life.
Can IRL540NSTRRPBF replace IRF540N in an existing design?
Yes, but only if gate drive voltage is ≥10 V. IRL540NSTRRPBF has identical pinout and RDS(on) at 10 V, yet its lower VGS(th) (1.0–2.0 V vs. 2.0–4.0 V) may cause unintended turn-on with floating gate traces. Verify gate drive strength and layout noise immunity before substitution.
Is the body diode suitable for reverse recovery in synchronous rectification?
No-the body diode has soft recovery (trr = 120 ns, Qrr = 190 nC) but lacks the optimized charge profile of dedicated synchronous rectifiers. It is acceptable for freewheeling in non-critical buck converters but not recommended for high-efficiency, high-frequency synchronous rectification where dedicated Schottky or GaN FETs are preferred.
Does IRL540NSTRRPBF meet RoHS and REACH requirements?
Yes-IRL540NSTRRPBF is lead-free and complies with RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006, as confirmed by Infineon's material declaration PD-95234 and packaging marking "P" indicating lead-free assembly per J-STD-609.
