Product details
Overview
IRL530NL from Infineon Technologies (formerly International Rectifier) is a 100V, 17A, N-channel enhancement-mode MOSFET in TO-220AB package with logic-level gate drive (VGS(th) = 1.0–2.0V), RDS(on) = 0.055Ω @ VGS = 10V, and integrated body diode optimized for fast switching in DC-DC converters and motor control. It operates in hard-switched buck topologies with continuous conduction mode.
For engineers reviewing the IRL530NL datasheet, IRL530NL pinout, IRL530NL application, or IRL530NL equivalent, key selection criteria include logic-level gate compatibility with 3.3V/5V microcontrollers, low RDS(on) for reduced conduction loss at 10–15A loads, body diode recovery performance in synchronous rectification, and TO-220 thermal interface suitability for heatsink-mounted industrial power stages.
Technical Context
This MOSFET uses planar vertical DMOS technology with optimized channel geometry to achieve low gate charge (Qg = 44nC) and fast turn-on/turn-off times (ton = 25ns, toff = 45ns). Its body diode exhibits reverse recovery time (trr) of 120ns and peak reverse recovery current (Irrm) of 12A under specified test conditions (IF = 17A, di/dt = 100A/µs).
The device supports unclamped inductive switching (UIS) up to 100mJ at TC = 25°C and features 100% avalanche-rated construction. Gate threshold voltage distribution ensures reliable turn-on with 4.5V logic drivers while maintaining noise immunity above 2.0V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 100V - Maximum drain-source blocking voltage for 24V/48V bus applications with 2× safety margin |
| ID (continuous) | 17A @ TC = 25°C - Sustains 15A load current in heatsinked TO-220 layout without derating |
| RDS(on) | 0.055Ω @ VGS = 10V - Delivers ≤1.4W conduction loss at 17A, enabling <85°C case temperature |
| VGS(th) | 1.0–2.0V - Fully enhanced by 3.3V GPIO or 5V logic outputs without level-shifting |
| Qg | 44nC - Enables 100kHz switching with <1W gate driver power dissipation using TC4427 |
| trr | 120ns - Limits diode commutation loss in non-synchronous flyback and buck converters |
Pinout & Package
IRL530NL is housed in a through-hole TO-220AB package with isolated tab (non-conductive mounting hole), standard lead pitch (2.54mm), and JEDEC outline TO-220AC dimensions (10.16 × 4.70 × 15.88 mm). Thermal resistance RθJC = 1.0°C/W enables direct heatsink attachment via M3 screw.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Drain (Tab) | Main current path output terminal | Electrically connected to metal tab - requires insulating washer when mounted to grounded heatsink |
| Source | Reference node for gate drive and current sensing | Low-inductance return path for load current; used as shunt connection point for current monitoring |
| Gate | Control electrode for channel modulation | High-impedance input requiring <100Ω series resistor to suppress ringing during fast edge transitions |
Key Features
| Feature | Design Value |
|---|---|
| Logic-level gate drive | Guaranteed turn-on at 4.5V VGS, eliminating need for dedicated gate driver ICs in MCU-based systems |
| Fast body diode recovery | 120ns trr reduces voltage overshoot and EMI in hard-switched inductive loads |
| Avalanche-rated construction | 100mJ single-pulse UIS rating protects against inductive kickback in relay/motor drive circuits |
| Lead-free (PbF) packaging | Complies with RoHS Directive 2011/65/EU; solderable with standard SnAgCu reflow profiles |
Applications
| Brushed DC Motor Drive | Buck Converter Power Stage |
|---|---|

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) = 0.075Ω @ 10V; VGS(th) = 2.0–4.0V; Qg = 35nC | Higher gate threshold requires 5V logic; lower Qg improves high-frequency efficiency | Prefer when gate drive is strictly 5V and switching frequency exceeds 300kHz |
| IRFZ44N | RDS(on) = 0.028Ω @ 10V; VGS(th) = 2.0–4.0V; no PbF option | Lower conduction loss but incompatible with 3.3V logic; legacy halogenated packaging | Choose only if 3.3V drive is absent and RoHS exemption applies |
Compared with STP16NF10 and IRFZ44N, the IRL530NL uniquely balances 3.3V logic compatibility, 0.055Ω conduction loss, and RoHS-compliant packaging-making it optimal for new industrial designs requiring mixed-voltage control and regulatory compliance.

FAQ
What is the maximum safe operating junction temperature for IRL530NL?
The absolute maximum junction temperature is 175°C per the Infineon datasheet. Derating begins at 125°C ambient when mounted on a 25°C/W heatsink with 17A current. Thermal shutdown is not built-in; external temperature monitoring is required for sustained >15A operation at elevated ambient temperatures.
Can IRL530NL be used in parallel configurations?
Yes-its positive temperature coefficient of RDS(on) enables current sharing. Parallel operation requires matched gate resistors (≤10Ω each), symmetrical PCB layout, and individual source resistors (0.01Ω) for current balancing. Up to three devices may be paralleled with proper thermal coupling and gate drive isolation.
Does IRL530NL have built-in ESD protection?
No-IRL530NL lacks on-chip ESD protection diodes. Gate oxide is rated for ±20V HBM per JEDEC JESD22-A114. External 10kΩ gate-to-source resistor and TVS diode (e.g., SMAJ5.0A) are mandatory for handling board-level ESD events during assembly or field operation.
Is the metal tab electrically connected to the drain terminal?
Yes-the TO-220AB package tab is internally bonded to the drain. When mounting to a heatsink, an insulating pad (e.g., Sil-Pad 1000) and shoulder washer must be used unless the heatsink is fully isolated. Voltage isolation between tab and source must exceed 100V for safe operation.
