Product details
Overview
IRL520NSPBF from Infineon Technologies (formerly International Rectifier) is a 100V, 9.2A, 0.27Ω N-channel enhancement-mode MOSFET in TO-220AB package, optimized for low-voltage DC-DC conversion and motor control with logic-level gate drive (VGS(th) = 1.0–2.0V). It features fast switching, low RDS(on), and integrated body diode with trr = 140 ns.
For engineers reviewing the IRL520NSPBF datasheet, IRL520NSPBF pinout, IRL520NSPBF application, or IRL520NSPBF equivalent, key selection criteria include gate threshold compatibility with 3.3V/5V microcontrollers, pulsed current capability (IDM = 36A), SOA limits at 100°C, and body diode reverse recovery performance in synchronous rectification.
Technical Context
This MOSFET uses planar V-groove silicon technology to achieve low on-resistance while maintaining rugged avalanche rating (EAS = 180 mJ). Its gate charge Qg = 24 nC and Qgs/Qgd ratio support efficient PWM operation up to 100 kHz in buck converters.
The device operates in enhancement mode with zero gate current and exhibits specified dV/dt immunity (50 V/ns) and di/dt ruggedness (100 A/µs), enabling reliable commutation in inductive loads without external snubbers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 100 V - Maximum drain-source blocking voltage for 24V/48V industrial power rails |
| RDS(on) @ VGS = 10V | 0.27 Ω - Enables ≤2.5W conduction loss at 9.2A continuous drain current |
| ID (continuous) | 9.2 A @ TC = 25°C - Sustained load current with TO-220AB heatsink mounting |
| Qg | 24 nC - Gate drive energy requirement for 100 kHz switching with <1.2 µs turn-on delay |
| trr (body diode) | 140 ns - Limits reverse recovery loss in freewheeling paths of half-bridge topologies |
| EAS | 180 mJ - Single-pulse avalanche energy rating supports inductive load switching without clamping |
Pinout & Package
IRL520NSPBF is housed in a through-hole TO-220AB package with isolated tab (non-conductive mounting), standard lead pitch (2.54 mm), and RoHS-compliant matte tin plating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Drain (Tab) | Main current path output | Electrically connected to metal tab - requires insulated mounting when referenced to ground |
| Source | Reference node for gate drive and current return | Common connection point for gate driver return and load current sensing |
| Gate | Control terminal | High-impedance input requiring <24 nC charge for full enhancement; sensitive to ESD |
Key Features
| Feature | Design Value |
|---|---|
| Logic-level gate drive | VGS(th) max = 2.0 V - Direct interface with 3.3V/5V MCU GPIO without level-shifting |
| Rugged body diode | trr = 140 ns, Qrr = 35 nC - Reduces switching loss in asynchronous buck and H-bridge freewheeling |
| Avalanche-rated | EAS = 180 mJ - Withstands inductive kickback during abrupt current interruption |
| Low gate charge | Qg = 24 nC - Minimizes driver power dissipation and enables high-frequency PWM |
Applications
| DC Motor Control | LED Constant-Current Driver |
|---|---|
Use Scenario: Bidirectional 24V brushed DC motor control in automated gate actuators. IC Role / Device Role / Timing Role: Low-side switch in H-bridge configuration, driven by PWM from ARM Cortex-M0+ MCU.

IC Role / Device Role / Timing Role: Switching element in buck-based current regulator operating at 25 kHz. Use Value: Fast trr and low Qg reduce switching losses to <0.4W, enabling >92% efficiency at 2A output. |

IC Role / Device Role / Timing Role: Self-oscillating quasi-resonant switch synchronized to transformer reset. Use Value: 100V VDS withstands reflected flyback spikes up to 85V, ensuring reliability across universal AC input. | Use Scenario: Reverse-polarity protection and source selection in dual-input 12V backup power system. IC Role / Device Role / Timing Role: Low-loss forward-path switch replacing Schottky diodes in ideal diode configuration. Use Value: RDS(on) = 0.27Ω cuts conduction loss by 65% vs. 40V Schottky, reducing thermal footprint by 3.2 cm². |
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 |
|---|---|---|---|
| IRF540N | VGS(th) = 2.0–4.0V; RDS(on) = 0.044Ω @ 10V; higher gate charge (71 nC) | Better conduction efficiency above 12A but requires 10V gate drive; unsuitable for 3.3V logic | Select when gate drive is ≥10V and peak current exceeds 12A |
| STP16NF10 | VGS(th) = 2.0–4.0V; RDS(on) = 0.22Ω @ 10V; lower ID (14A) and EAS (120 mJ) | Marginally lower RDS(on) but reduced avalanche robustness; not rated for repetitive inductive switching | Select only for non-inductive loads where avalanche stress is absent |
Compared with IRL520NSPBF, IRF540N delivers lower conduction loss at high current but demands higher gate voltage and increases driver complexity, while STP16NF10 trades avalanche safety for marginal RDS(on) improvement-making IRL520NSPBF optimal for 3.3V/5V-controlled inductive switching with reliability-critical SOA requirements.

FAQ
What is the maximum safe operating junction temperature for IRL520NSPBF?
The absolute maximum junction temperature is 175°C. Derated continuous current drops to 5.8A at TC = 100°C per the SOA curve. Thermal design must maintain case temperature ≤100°C using ≥15 cm² copper pour or clip-on heatsink to ensure 10-year field reliability under 7A RMS load.
Can IRL520NSPBF be used in parallel configurations?
Yes, but only with matched devices and individual gate resistors (≥10Ω) to prevent current imbalance. The positive temperature coefficient of RDS(on) provides inherent current sharing above 80°C, though layout symmetry and Kelvin-source routing are mandatory for stable 2× parallel operation at >15A total.
Does IRL520NSPBF require a gate resistor for 5V MCU drive?
A 10–22Ω series gate resistor is recommended to dampen ringing and limit peak gate current. Without it, the 24 nC gate charge interacting with PCB trace inductance can cause overshoot >7V and oscillation near 120 MHz, risking false turn-on or gate oxide stress during fast edge transitions.
Is the TO-220AB tab electrically isolated in IRL520NSPBF?
Yes-the TO-220AB package uses an insulated tab construction. Drain is connected to the tab, but the mounting surface remains electrically isolated via molded plastic barrier. This allows direct heatsink attachment without insulating hardware, provided the heatsink is not referenced to circuit ground.
