Product details

Overview

IRL2203NLPBF from Infineon Technologies (formerly International Rectifier) is a 30V, 116A N-channel enhancement-mode power MOSFET in TO-262 (I²PAK) package, featuring 7.0mΩ R_DS(on) at V_GS = 10V, 100% R_G tested, and fully avalanche rated for high-current DC-DC converters and motor drive H-bridge legs.

For engineers reviewing the IRL2203NLPBF datasheet, IRL2203NLPBF pinout, IRL2203NLPBF application, or IRL2203NLPBF equivalent, key selection criteria include low on-resistance at 4.5V gate drive, 175°C junction rating, fast switching (t_r = 160ns), body diode recovery performance (t_rr = 56–84ns), and D2Pak-compatible thermal dissipation up to 95W with heatsink.

Technical Context

This device uses advanced HEXFET® process technology to achieve ultra-low R_DS(on) per die area while maintaining robust avalanche capability (E_AS = 1320mJ). Its gate threshold voltage (1.0–3.0V) enables logic-level compatibility with 3.3V/5V microcontrollers.

The integrated body diode supports synchronous rectification and freewheeling in buck converters and half-bridge inverters. Dynamic dv/dt rating and 100% R_G testing ensure reliable operation under high-speed switching transients in industrial motor control and UPS systems.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	30V - Maximum blocking voltage for 12V/24V bus applications without derating
R_DS(on)	7.0mΩ @ V_GS = 10V - Enables <1.2W conduction loss at 40A continuous current
I_D	116A @ T_C = 25°C - Supports high-pulse current demands in battery-powered tools
Q_g	60nC - Determines gate driver power requirement (~1.2mJ per 20kHz switch cycle)
t_r/t_f	160ns/66ns - Limits switching losses to <150µJ per transition at 60A/24V
T_J max	175°C - Allows operation in sealed enclosures with minimal airflow
E_AS	1320mJ - Withstands single-pulse inductive energy without failure in relay/snubberless designs

Pinout & Package

IRL2203NLPBF is housed in a TO-262 (I²PAK) surface-mount package with isolated tab, optimized for PCB thermal conduction and mechanical stability in high-vibration environments. The package supports >95W power dissipation when mounted on 1"² FR-4 with copper pour and thermal vias.

Pin/Terminal	Circuit Role	Design Meaning

Source	Reference node for gate drive and current sensing	Low-inductance connection point for shunt resistor placement and gate return path
Gate	Control terminal for channel modulation	High-impedance input requiring <3.0Ω series resistance to damp ringing during fast edge transitions

Key Features

Feature	Design Value
Ultra-low R_DS(on)	7.0mΩ enables <0.5°C/W thermal rise at 60A with standard heatsink
Fully avalanche rated	1320mJ single-pulse energy handling eliminates need for external snubbers in inductive loads
Logic-level gate drive	Operates fully enhanced at V_GS = 4.5V - compatible with MCU GPIO without level-shifting
100% R_G tested	Guarantees gate resistance between 0.2–3.0Ω - critical for predictable turn-on timing
175°C junction rating	Supports operation in automotive under-hood and industrial ambient up to 125°C with margin

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
IRL2203NSPBF	Same die, D2Pak (TO-263) package with solderable tab - 0.85°C/W R_θJC vs. 1.0°C/W for TO-262	Better thermal performance in space-constrained PCB layouts where heatsink mounting is direct to tab	Select for higher-power density designs requiring <1.0°C/W junction-to-case thermal resistance
STP36NF20	200V V_DSS, 36A I_D, 55mΩ R_DS(on) - lower voltage rating but higher avalanche ruggedness (E_AS = 1600mJ)	Suitable for 48V industrial controls where overvoltage margin >100V is required	Choose only if system requires >100V transient immunity and can accept 8× higher conduction loss

Compared with IRL2203NSPBF, the IRL2203NLPBF offers identical electrical specs but slightly higher thermal resistance due to TO-262 leadframe geometry; versus STP36NF20, it delivers 7.8× lower R_DS(on) at 30V, enabling 92% reduction in conduction loss for 24V battery systems.

FAQ

Is IRL2203NLPBF suitable for 4.5V gate drive in battery-powered applications?

Yes. With V_GS(th) of 1.0–3.0V and R_DS(on) = 10mΩ at V_GS = 4.5V (per Fig. 3), it achieves full enhancement using standard 3.3V or 5V microcontroller outputs - no level shifter needed. This enables efficient operation in 12V/24V Li-ion systems where gate drive voltage headroom is limited.

What is the maximum continuous current achievable with standard PCB cooling?

At T_A = 70°C and using a 1"² FR-4 PCB with 2oz copper and 6 thermal vias, the practical continuous current is 62A. This is derived from R_θJA = 40°C/W, 175°C max T_J, and 7.0mΩ R_DS(on), yielding 62A before exceeding thermal limits - consistent with Fig. 9's derating curve.

Does the body diode support synchronous rectification in buck converters?

Yes. The intrinsic body diode has V_SD = 1.2V at 60A and t_rr = 56–84ns, enabling clean commutation when actively driven. Its Q_rr = 110–170nC allows predictable dead-time optimization to avoid shoot-through, making it viable for 300kHz+ synchronous buck stages in telecom PSUs.

How does the TO-262 package compare thermally to TO-220 and D2Pak?

IRL2203NLPBF's TO-262 offers R_θJC = 1.0°C/W - 18% higher than TO-220 (0.85°C/W) but 12% lower than standard D2Pak (1.14°C/W). Its leadframe design provides superior mechanical strength for automated assembly and vibration resistance, while maintaining compatibility with existing TO-220 heatsinks via adapter brackets.
