Product details

Overview

IRL2203NSPbF from Infineon Technologies (formerly International Rectifier) is a 30V, 116A N-channel enhancement-mode power MOSFET in D2PAK surface-mount package, featuring 7.0 mΩ R_DS(on) at V_GS = 10 V, fully avalanche-rated operation, and 175°C maximum junction temperature - deployed in high-current DC-DC converter primary-side switches and motor phase-leg drivers.

For engineers reviewing the IRL2203NSPbF datasheet, IRL2203NSPbF pinout, IRL2203NSPbF application, or IRL2203NSPbF equivalent, key selection criteria include low on-resistance for conduction loss minimization, fast switching (t_r = 160 ns, t_f = 66 ns), rugged body diode performance (t_rr = 56–84 ns), and thermal capability (R_θJC = 0.85 °C/W) in high-power surface-mount designs.

Technical Context

This HEXFET® device uses advanced silicon processing to achieve ultra-low R_DS(on) per die area while maintaining robust avalanche energy rating (E_AS = 1320 mJ) and dynamic dv/dt immunity. Its gate threshold voltage (1.0–3.0 V) enables direct logic-level drive from 3.3 V/5 V controllers.

The integrated body diode supports synchronous rectification and freewheeling in H-bridge and buck topologies. Thermal design leverages low junction-to-case resistance (0.85 °C/W) and high continuous current rating (116 A at T_C = 25°C), limited by package rather than silicon at 75 A under PCB-mount conditions.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	30 V - Maximum blocking voltage for 12 V and 24 V bus applications with margin against transients
R_DS(on)	7.0 mΩ @ V_GS = 10 V - Enables <1 W conduction loss at 116 A, critical for high-efficiency power stages
I_D	116 A @ T_C = 25°C - High continuous current capacity suitable for motor drives and industrial SMPS
Q_g	60 nC - Gate charge value defining driver strength requirement for 100 kHz+ switching
t_r/t_f	160 ns / 66 ns - Fast edge rates reduce switching losses in hard-switched converters
E_AS	1320 mJ - Single-pulse avalanche energy enabling reliable operation during inductive turn-off stress
R_θJC	0.85 °C/W - Low thermal resistance allows >95% of rated power dissipation to be transferred directly to heatsink

Pinout & Package

D2PAK (TO-262) surface-mount package with isolated tab (drain-connected), optimized for high-current PCB mounting and thermal interface to external heatsinks. Standard footprint per IR application note AN-994.

Pin/Terminal	Circuit Role	Design Meaning
Tab (exposed pad)	Drain (D)	Primary current path and thermal conduction path; electrically connected to drain, requires insulated mounting or grounded heatsink
Lead 1	Source (S)	Main source terminal; carries full load current and serves as reference for gate drive return path
Lead 2	Gate (G)	Control input; low gate charge (60 nC) enables efficient drive with standard MOSFET drivers

Key Features

Feature	Design Value
Ultra-low R_DS(on)	7.0 mΩ reduces conduction loss by >40% vs. legacy 30 V MOSFETs in 48 A+ applications
Fully avalanche-rated	1320 mJ single-pulse E_AS eliminates need for external snubbers in inductive switching circuits
Logic-level gate drive	V_GS(th) = 1.0–3.0 V ensures full enhancement with 3.3 V microcontroller outputs without level-shifting
Rugged body diode	t_rr = 56–84 ns and Q_rr = 110–170 nC support efficient synchronous rectification and minimize commutation loss
High-temperature operation	Rated to 175°C junction temperature enables use in sealed enclosures and high-ambient industrial environments

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
STP120N3LLH6	R_DS(on) = 3.3 mΩ @ 10 V, but 100 A rating and TO-220FP package - higher thermal resistance (R_θJC = 1.5 °C/W)	Better conduction loss, but unsuitable for surface-mount high-density layouts requiring D2PAK footprint	Select when lower R_DS(on) justifies through-hole assembly and larger heatsink volume
IRF1404ZLPBF	R_DS(on) = 4.7 mΩ @ 10 V, 200 A rating, TO-262 package - higher gate charge (131 nC) and slower switching (t_r = 220 ns)	Higher current headroom but increased driver loss and EMI in high-frequency designs	Select when peak current >116 A is required and switching frequency <100 kHz

Compared with STP120N3LLH6 and IRF1404ZLPBF, the IRL2203NSPbF offers optimal balance of low R_DS(on), fast switching, surface-mount compatibility, and thermal efficiency - making it preferred for space-constrained, high-frequency, high-current applications where D2PAK mounting is specified.

FAQ

Is the IRL2203NSPbF RoHS-compliant and lead-free?

Yes, the "PbF" suffix confirms compliance with RoHS Directive 2011/65/EU and JEDEC J-STD-609. The device uses matte tin plating over copper leads and lead-free solder-compatible terminations. No lead content is present in die attach, mold compound, or internal interconnects.

Can the IRL2203NSPbF be used with 3.3 V microcontroller GPIOs?

Yes - its gate threshold voltage range (1.0–3.0 V) ensures full enhancement at 3.3 V drive. At V_GS = 4.5 V, R_DS(on) remains ≤10 mΩ, supporting >80 A continuous current with acceptable conduction loss in logic-level applications.

What is the maximum recommended PCB copper area for thermal relief?

Per IR application note AN-994, a minimum 1" × 1" (25.4 mm × 25.4 mm) 2-oz copper pour connected to the exposed drain tab via ≥8 thermal vias (0.3 mm diameter, spaced ≤1.5 mm apart) achieves R_θJA ≈ 40 °C/W and supports 952 W power dissipation at ΔT = 38°C.

Does the body diode support continuous reverse conduction in synchronous rectification?

Yes - the intrinsic body diode is rated for 116 A continuous source current (I_S) and 400 A pulsed (I_SM). Its 1.2 V forward drop at 60 A and 56 ns reverse recovery time make it suitable for synchronous rectification in buck converters up to 500 kHz with proper gate timing control.
