Product details
Overview
IRL520NSTRL from Infineon Technologies (formerly International Rectifier) is a 100V, 5.9A N-channel enhancement-mode MOSFET in TO-220AB package, optimized for low-voltage DC-DC conversion and motor control with RDS(on) = 0.27Ω @ VGS = 10V and Qg = 14nC. It features an integrated fast-recovery body diode and supports pulsed drain current up to 22A.
For engineers reviewing the IRL520NSTRL datasheet, IRL520NSTRL pinout, IRL520NSTRL application, or IRL520NSTRL equivalent, key selection criteria include gate threshold voltage (VGS(th) = 2.0V min), safe operating area (SOA) at 100µs, and body diode reverse recovery time (trr = 120ns), critical for synchronous buck and H-bridge designs.
Technical Context
This MOSFET employs planar stripe DMOS technology with optimized channel geometry for enhanced switching efficiency and thermal stability. Its low gate charge enables fast turn-on/turn-off with minimal driver power loss, while the specified dV/dt immunity (≥4.5V/ns) ensures robust operation in noisy industrial environments.
The device is characterized for operation across -55°C to +175°C junction temperature range and supports repetitive avalanche energy rating (EAS = 85mJ), enabling reliable use in inductive load switching without external snubbers.

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 |
|---|---|---|---|
| STP55NF06L | RDS(on) = 0.022Ω @ 10V (lower), but VDS = 60V (reduced voltage margin) | Preferred in 24V systems where lower conduction loss outweighs 100V requirement | Select when operating below 40V and thermal budget is tight |
| IRFZ44N | RDS(on) = 0.028Ω @ 10V, but trr = 140ns (slower body diode) | Suitable for non-synchronous or low-frequency switching where diode speed is less critical | Choose for cost-sensitive 50Hz–100kHz applications without fast recovery demands |
Compared with STP55NF06L and IRFZ44N, the IRL520NSTRL provides optimal balance of 100V rating, logic-level drive, and fast body diode-making it uniquely suited for 48V industrial motor drives where both voltage headroom and switching efficiency are required.

FAQ
Is IRL520NSTRL suitable for 5V microcontroller gate drive without a level shifter?
Yes. With VGS(th) ranging from 2.0V to 4.0V and full enhancement at VGS = 5V, the IRL520NSTRL operates reliably using direct GPIO drive from 5V or 3.3V MCUs. Gate charge of 14nC ensures fast switching even with 20mA drive capability, and no external level-shifting circuitry is required for standard logic-level interfaces.
What is the maximum pulsed drain current rating and under what conditions?
The IRL520NSTRL supports IDM = 22A for pulse widths ≤ 100µs at duty cycle ≤ 1%, with case temperature ≤ 25°C. This rating assumes adequate PCB copper area (≥1in² 2oz copper) and transient thermal impedance of 0.8°C/W for short-duration overload events such as motor startup or inrush limiting.
Does the TO-220AB package provide electrical isolation between drain and mounting surface?
No. The metal tab is internally connected to the Drain terminal. Electrical isolation requires a mica or ceramic insulator plus shoulder washer during heatsink mounting. Thermal resistance from junction-to-case is 1.5°C/W, and isolation voltage depends on the insulator used-not the package itself.
Can IRL520NSTRL replace IRF520 in existing designs?
Yes, with verified improvement. Both share TO-220AB footprint and pinout, but IRL520NSTRL offers lower RDS(on) (0.27Ω vs. 0.9Ω), logic-level drive (VGS(th) ≤ 4.0V vs. 2–4V), and faster trr (120ns vs. 200ns). No layout changes are needed, and gate drive requirements are relaxed-enabling direct upgrade in 24V motor and SMPS applications.
