Product details
Overview
IRL530NPBF from Infineon Technologies is a 100 V, 17 A, 0.11 Ω (at VGS = 10 V) N-channel enhancement-mode HEXFET power MOSFET in TO-220AB package, optimized for low-voltage DC-DC conversion and motor control switching applications.
For engineers reviewing the IRL530NPBF datasheet, IRL530NPBF pinout, IRL530NPBF application, or IRL530NPBF equivalent, key selection criteria include RDS(on) at 5 V gate drive, SOA robustness in linear mode, avalanche energy rating (EAS = 140 mJ), and thermal resistance (RθJC = 1.2 °C/W).
Technical Context
This MOSFET uses planar stripe cell technology with optimized gate oxide thickness to achieve enhanced transconductance and reduced gate charge (Qg = 38 nC). Its threshold voltage (VGS(th)) ranges from 1.0 V to 2.0 V, enabling reliable turn-on with 3.3 V or 5 V logic-level drivers.
The device features an integrated avalanche-rated structure and specified unclamped inductive switching (UIS) capability. Its drain-source diode exhibits soft recovery characteristics with reverse recovery time (trr) of 120 ns and Qrr of 120 nC at IF = 17 A.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 100 V - maximum blocking voltage for 24–48 V bus systems |
| ID (continuous) | 17 A @ TC = 25 °C - supports medium-power switching up to ~200 W with heatsink |
| RDS(on) | 0.11 Ω @ VGS = 10 V - enables <1.9 W conduction loss at 4.2 A RMS |
| Qg | 38 nC - determines gate drive power requirement and switching speed |
| EAS | 140 mJ - specifies single-pulse avalanche energy handling without failure |
| RθJC | 1.2 °C/W - defines junction-to-case thermal resistance for heatsink sizing |
Pinout & Package
IRL530NPBF is housed in a through-hole TO-220AB package with isolated tab (drain-connected), rated for 175 °C maximum junction temperature and compatible with standard TO-220 heatsinks.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Gate) | Control electrode | Receives voltage-controlled signal; requires ≤ ±20 V max; high input impedance |
| 2 (Drain) | High-side current path | Connected to load supply rail; electrically tied to metal tab for thermal conduction |
| 3 (Source) | Reference node | Common return for gate drive and load current; establishes VGS reference |
| 4 (Drain) | Secondary drain connection | Parallel drain path to reduce package inductance and improve current sharing |

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 |
|---|---|---|---|
| STP16NF10 | RDS(on) = 0.18 Ω @ 10 V; higher threshold (2–4 V); lower ID (16 A) | Less suitable for 3.3 V logic drive; requires higher gate voltage for full enhancement | Prefer when cost sensitivity outweighs RDS(on) and gate drive margin requirements |
| IRFZ44NPBF | RDS(on) = 0.028 Ω @ 10 V; lower VDS (55 V); same TO-220AB package | Not rated for 100 V bus systems; limited to ≤40 V applications | Select only for 24 V systems where ultra-low conduction loss is critical and voltage headroom is sufficient |
Compared with STP16NF10 and IRFZ44NPBF, IRL530NPBF uniquely balances 100 V rating, logic-level gate compatibility, and 0.11 Ω conduction resistance-making it optimal for 24–48 V industrial switching where both voltage margin and 5 V MCU interfacing matter.

FAQ
Is IRL530NPBF suitable for 3.3 V microcontroller gate drive?
Yes. With a guaranteed VGS(th) as low as 1.0 V and RDS(on) = 0.16 Ω at VGS = 4.5 V, the IRL530NPBF fully enhances using 3.3 V logic outputs. However, for lowest RDS(on), 5 V or higher gate drive is recommended to achieve 0.11 Ω.
What is the maximum safe operating area (SOA) for linear-mode operation?
The IRL530NPBF SOA curve is defined up to 100 V and 17 A at TC = 25 °C, with derating to 8.5 A at 100 V when TC = 100 °C. It supports short-duration linear operation (e.g., active current limiting) but is not intended for sustained analog amplification.
Does the TO-220AB package have an electrically isolated tab?
No. Pin 2 and Pin 4 are internally connected to the drain and to the metal tab. The tab is not electrically isolated and must be insulated from heatsinks unless the heatsink is referenced to the drain potential.
How does the "P" suffix affect soldering profile and reliability?
The "P" suffix indicates lead-free (Pb-free) construction per JEDEC J-STD-020. It requires peak reflow temperatures of 260 °C (vs. 240 °C for SnPb), with strict ramp rate control. Reliability testing confirms equivalent thermal cycling and moisture sensitivity (MSL 1) performance versus legacy versions.
