Product details
Overview
IRL540NSTRR 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 VGS = 5 V, optimized for high-efficiency DC-DC converters and motor control stages.
For engineers reviewing the IRL540NSTRR datasheet, IRL540NSTRR pinout, IRL540NSTRR application, or IRL540NSTRR equivalent, key selection criteria include logic-level gate drive compatibility, low conduction loss at 5 V gate bias, thermal performance in surface-mount power stages, and SOA compliance under repetitive pulse conditions.
Technical Context
This MOSFET employs planar stripe cell structure with optimized channel density and reduced specific on-resistance. Its threshold voltage range (1.0–2.0 V) enables reliable turn-on with standard 3.3 V or 5 V microcontroller outputs without gate boosting.
The device integrates an internal body diode with 120 ns reverse recovery time (trr) and 45 A peak forward current rating, supporting synchronous rectification and freewheeling in buck and half-bridge topologies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 100 V - supports input rails up to 48 V nominal systems with 2× safety margin |
| ID (continuous, TC = 100°C) | 36 A - delivers sustained output current in thermally constrained PCB layouts |
| RDS(on) @ VGS = 10 V | 44 mΩ - limits conduction loss to ≤1.6 W at 6 A load in typical SMPS designs |
| RDS(on) @ VGS = 5 V | 55 mΩ - ensures functional switching with logic-level drivers without external level shifters |
| Qg | 71 nC - determines gate drive power requirement and switching speed in 100 kHz–500 kHz applications |
| tr/tf | 30/60 ns - enables fast transition control to minimize overlap loss in hard-switched converters |
| SOA (10 ms) | 100 V / 12 A - defines safe single-pulse energy handling during inrush or fault events |
Pinout & Package
D2PAK (TO-263) surface-mount package with exposed drain pad for enhanced thermal dissipation; 3-pin configuration (G-D-S), 10.67 mm × 9.65 mm footprint, 4.83 mm height, recommended solder stencil aperture 1.0 mm × 1.0 mm for thermal pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Gate (G) | Control terminal | Accepts 0–10 V logic-compatible signals; requires ≤71 nC charge for full enhancement |
| Drain (D) | High-side power output | Connected to load or bus rail; electrically tied to exposed copper pad for thermal path |
| Source (S) | Reference node | Return path for load current; establishes common reference for gate drive loop |
Key Features
| Feature | Design Value |
|---|---|
| Logic-level gate drive | Operates fully enhanced at VGS = 5 V, eliminating need for gate driver ICs in MCU-based power stages |
| Low RDS(on) at 5 V | 55 mΩ enables <1.5 W conduction loss at 5.5 A, critical for compact 12 V input DC-DC modules |
| Enhanced SOA | Rated for 100 V × 12 A for 10 ms - supports robust operation during motor stall or output short events |
| Fast body diode | 120 ns trr and soft recovery reduce EMI in synchronous rectifier configurations |

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel logic-level MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STP36NF10 | RDS(on) = 32 mΩ @ 10 V but 75 mΩ @ 5 V; higher Qg (105 nC) | Less suitable for 5 V gate drive; better for 10 V gate systems with higher efficiency priority | Select when gate drive voltage ≥8 V and lower RDS(on) at 10 V is critical |
| IRFZ44NPBF | RDS(on) = 28 mΩ @ 10 V but only rated to 55 V VDS; no 5 V RDS(on) spec | Not usable in 48 V bus systems; limited to ≤36 V input applications | Choose only for cost-sensitive 24 V systems where 100 V rating is unnecessary |
Compared with STP36NF10 and IRFZ44NPBF, IRL540NSTRR uniquely balances 100 V rating, verified 5 V drive capability, and SOA robustness-making it optimal for industrial 48 V power stages requiring logic-level compatibility and fault resilience.

FAQ
What is the maximum continuous drain current for IRL540NSTRR at 25°C case temperature?
The maximum continuous drain current (ID) is 36 A at TC = 100°C. At TC = 25°C, the absolute maximum is limited by package SOA and bond wire rating to 110 A for short pulses, but continuous operation remains capped at 36 A due to thermal saturation of the D2PAK package under real PCB mounting conditions.
Does IRL540NSTRR have avalanche rating, and if so, what is its EAS value?
Yes, IRL540NSTRR is 100% avalanche tested with EAS = 125 mJ at TJ = 25°C. This rating applies to single-pulse inductive switching events and is validated per JEDEC JESD24-11 test conditions using 100 V, 12 A, and 10 ms pulse width.
Can IRL540NSTRR be used in parallel configurations, and what precautions are required?
Yes, parallel operation is supported due to positive temperature coefficient of RDS(on). Required precautions include matched gate resistors (≤1 Ω), symmetrical PCB layout with equal trace lengths, and individual source inductance minimization (<10 nH) to prevent current imbalance above 15 A total load.
What is the thermal resistance RθJC for IRL540NSTRR, and how does it affect heatsink selection?
RθJC is 0.45°C/W from junction to case. With 36 A continuous current and 55 mΩ RDS(on), power dissipation reaches ~70 W at worst-case VGS = 5 V, requiring a heatsink with RθCA ≤ 1.0°C/W to maintain TJ ≤ 150°C at 50°C ambient, assuming 1.5 W conduction loss margin.
