Product details
Overview
IRL530NSTRL from Infineon Technologies (formerly International Rectifier) is a 100V, 17A, N-channel logic-level power MOSFET in TO-220AB package, with RDS(on) = 0.16 Ω at VGS = 10 V and 0.27 Ω at VGS = 5 V, optimized for DC-DC converters and motor control where gate drive voltage is limited to 5 V.
For engineers reviewing the IRL530NSTRL datasheet, IRL530NSTRL pinout, IRL530NSTRL application, or IRL530NSTRL equivalent, key selection criteria include logic-level gate threshold (VGS(th) = 1.0–2.0 V), body diode recovery performance, continuous drain current rating at 100°C case temperature, and TO-220AB thermal resistance (RθJC = 1.25 °C/W).
Technical Context
This MOSFET employs planar stripe DMOS technology with integrated fast-recovery body diode, enabling efficient unidirectional current flow in flyback and synchronous rectification topologies. Its low gate charge (Qg = 32 nC typical) and low input capacitance (Ciss = 820 pF) support high-frequency switching up to 500 kHz.
The device features avalanche-rated ruggedness (EAS = 140 mJ at TJ = 25°C), specified for repetitive unclamped inductive switching, and meets JEDEC JESD47 reliability standards for industrial-grade operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 100 V - maximum blocking voltage before avalanche onset; suitable for 48 V bus systems with 2× safety margin |
| ID (continuous, TC = 100°C) | 17 A - sustained current capability with heatsink; defines minimum heatsink size for 10 W conduction loss |
| RDS(on) @ VGS = 5 V | 0.27 Ω - enables direct 5 V microcontroller gate drive without level-shifting circuitry |
| Qg | 32 nC - determines gate driver power requirement and switching transition time at 100 kHz |
| Body diode trr | 60 ns - limits reverse recovery losses in hard-switched inductive loads like solenoid drivers |
| RθJC | 1.25 °C/W - sets junction-to-case thermal gradient; used to calculate max allowable PD at given TC |
Pinout & Package
TO-220AB package: isolated tab (drain), 3-pin through-hole mounting, 2.54 mm lead pitch, 4.8 mm lead width, 15.9 mm total height. Tab electrically connected to drain terminal.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Gate) | Control electrode | Receives logic-level voltage (≥4.5 V) to fully enhance channel; sensitive to ESD (HBM 2 kV) |
| 2 (Drain) | High-side current path | Connected to heat sink via isolated tab; carries full load current and withstands 100 V transients |
| 3 (Source) | Reference node | Serves as return path for gate drive and load current; common reference for PWM controller feedback |
Key Features
| Feature | Design Value |
|---|---|
| Logic-level gate drive compatibility | Guaranteed turn-on at VGS = 4.5 V, eliminating need for gate driver ICs in 5 V systems |
| Fast body diode recovery | trr = 60 ns with soft recovery waveform reduces EMI and snubber losses in flyback converters |
| Avalanche energy rating | EAS = 140 mJ supports robust operation during inductive load switching without external clamping |
| Lead-free and RoHS-compliant | Meets IPC/JEDEC J-STD-020 moisture sensitivity level 1; no pre-bake required for surface-mount assembly |
Applications
| DC-DC Buck Converter | Brushed DC Motor Driver |
|---|---|
Use Scenario: 12 V input to 5 V/10 A output step-down regulator in industrial PLC I/O modules. IC Role / Device Role / Timing Role: Synchronous rectifier switch replacing Schottky diode to reduce conduction loss by 40%. Use Value: Achieves >92% efficiency at full load due to RDS(on) = 0.27 Ω at 5 V gate drive. | Use Scenario: H-bridge half-bridge leg driving 24 V, 8 A brushed motor in automated gate actuator. IC Role / Device Role / Timing Role: Low-side switch controlling motor direction and PWM speed regulation. Use Value: Enables 20 kHz PWM without excessive gate drive power, thanks to Qg = 32 nC. |
| LED Constant-Current Driver | Power Supply OR-ing Circuit |
Use Scenario: Dimmable 36 V, 1.5 A LED string driver using constant-current buck topology. IC Role / Device Role / Timing Role: Main switching element modulating average current through sense-resistor feedback loop. Use Value: Maintains ±2% current accuracy across line and temperature due to stable RDS(on) drift (<0.4%/°C). | Use Scenario: Dual-input 48 V telecom power system with automatic source selection and fault isolation. IC Role / Device Role / Timing Role: Ideal diode replacement providing forward conduction and reverse blocking with <100 mV drop. Use Value: Reduces power dissipation by 75% vs. Schottky diode, lowering thermal design burden. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel logic-level power MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STP16NF10 | RDS(on) = 0.22 Ω @ 5 V, higher Qg = 45 nC, same VDS/ID ratings | Less suitable for >200 kHz switching due to higher gate charge | Prefer when lower RDS(on) outweighs switching loss penalty in 50–100 kHz designs |
| FQP30N06L | VDS = 60 V only, RDS(on) = 0.035 Ω @ 5 V, lower thermal resistance (RθJC = 1.0 °C/W) | Not rated for 48 V bus systems requiring 100 V blocking margin | Select only for ≤36 V input applications where ultra-low on-resistance is critical |
Compared with STP16NF10 and FQP30N06L, IRL530NSTRL uniquely balances 100 V rating, 5 V drive capability, and moderate gate charge-making it optimal for industrial 48 V DC-DC and motor control where both voltage margin and microcontroller compatibility are required.

FAQ
What is the maximum safe operating temperature for IRL530NSTRL?
The IRL530NSTRL has a maximum junction temperature of 175°C and is rated for continuous operation up to 100°C case temperature. At TC = 100°C, its 17 A current rating assumes proper heatsinking with RθJA ≤ 40°C/W in still air. Derating is required above 100°C case temperature per the datasheet's thermal curves.
Does IRL530NSTRL have built-in ESD protection?
Yes, the IRL530NSTRL features integrated gate oxide protection with Human Body Model (HBM) ESD rating of 2 kV per JEDEC JS-001. However, standard MOSFET handling precautions-including grounded workstations and anti-static packaging-are still required during PCB assembly and handling.
Can IRL530NSTRL be used in linear (analog) mode?
No, the IRL530NSTRL is not characterized or guaranteed for linear-mode operation. Its Safe Operating Area (SOA) curve is defined only for pulsed switching conditions. Continuous linear operation risks thermal runaway due to positive temperature coefficient of RDS(on) and insufficient SOA margin at low VDS/high ID.
Is the TO-220AB package electrically insulated?
No, the TO-220AB package has an electrically conductive drain-connected tab. The metal tab is internally bonded to the drain terminal and must be isolated from heatsinks using mica washers or silicone thermal pads with ≥2.5 kV dielectric strength if the heatsink is grounded or at a different potential.
