Product details

Overview

IRLR2703TRL from Infineon Technologies (formerly International Rectifier) is a 30V, 23A logic-level N-channel Power MOSFET in TO-252AA (D-Pak) surface-mount package, featuring R_DS(on) = 45 mΩ @ V_GS = 10 V and 65 mΩ @ V_GS = 4.5 V, fully avalanche-rated, and optimized for DC-DC converters, motor drives, and load switching in industrial power supplies.

For engineers reviewing the IRLR2703TRL datasheet, IRLR2703TRL pinout, IRLR2703TRL application, or IRLR2703TRL equivalent, key selection criteria include logic-level gate drive compatibility (V_GS(th) = 1.0–2.5 V), low thermal resistance (R_θJC = 3.3 °C/W), fast switching (t_r = 140 ns, t_f = 20 ns), and rugged unclamped inductive switching capability (E_AS = 77 mJ).

Technical Context

This fifth-generation HEXFET device uses advanced planar processing to minimize on-resistance per die area while maintaining high avalanche energy rating (E_AS = 77 mJ) and robust dv/dt immunity (5.0 V/ns). Its body diode exhibits t_rr = 65–97 ns and Q_rr = 140–210 nC under specified conditions.

The MOSFET operates across –55°C to +175°C junction temperature range with ±16 V gate voltage tolerance and integrates low-inductance internal source (L_S = 7.5 nH) and drain (L_D = 4.5 nH) leads-critical for minimizing switching oscillation in high-frequency synchronous buck stages.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	30 V - Maximum blocking voltage in high-side switch or synchronous rectifier configurations
R_DS(on) @ 10 V	45 mΩ - Enables ≤1.0 W conduction loss at 14 A continuous drain current
R_DS(on) @ 4.5 V	65 mΩ - Supports direct microcontroller GPIO drive without level-shifting circuitry
I_D @ T_C = 25°C	23 A - Continuous current rating under ideal heatsinking (PCB copper pour)
E_AS	77 mJ - Withstands single-pulse inductive energy during fault events in motor control
Q_g	15 nC - Determines gate driver power requirement and switching transition time
t_r/t_f	140 ns / 20 ns - Enables efficient operation up to ~500 kHz in hard-switched topologies
R_θJC	3.3 °C/W - Allows direct thermal path to PCB copper or external heatsink for high-power density designs

Pinout & Package

IRLR2703TRL is housed in a TO-252AA (D-Pak) thermally enhanced surface-mount package with exposed drain pad for low-inductance, low-thermal-resistance mounting. The package conforms to JEDEC outline and supports vapor-phase, infrared, and wave soldering.

Pin/Terminal	Circuit Role	Design Meaning
1 - Gate	Control terminal	Receives logic-level input (1.0–2.5 V threshold); requires <15 nC total charge for full enhancement
2 - Drain	High-side power node	Internally connected to exposed metal tab; primary thermal and current path to PCB copper pour
3 - Source	Power return reference	Provides low-inductance return path (L_S = 7.5 nH); ties to ground plane or low-side switch source
4 - Drain	Redundant drain connection	Electrically tied to Pin 2; enhances current sharing and thermal spreading across PCB footprint

Key Features

Feature	Design Value
Logic-level gate drive	V_GS(th) = 1.0–2.5 V enables direct interface with 3.3 V/5 V MCUs and PWM controllers
Fully avalanche rated	Single-pulse E_AS = 77 mJ ensures reliability in unclamped inductive switching (e.g., relay coils, solenoids)
Ultra-low R_DS(on)	45 mΩ @ 10 V reduces conduction losses by >30% vs. legacy D-Pak MOSFETs at same current
Fast switching speed	140 ns rise / 20 ns fall times support high-frequency SMPS designs with minimal dead-time penalty
Thermally optimized package	R_θJC = 3.3 °C/W allows >40 W power dissipation with modest PCB copper area (≥2 in²)

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
IRLR3103PBF	R_DS(on) = 32 mΩ @ 10 V; higher ID (33 A); larger die size increases gate charge (Q_g = 22 nC)	Better conduction efficiency at >15 A but slower switching; requires stronger gate driver	Select when conduction loss dominates and switching frequency ≤200 kHz
STP36NF20L	V_DS = 200 V; R_DS(on) = 50 mΩ @ 10 V; higher threshold (2.5–4.5 V); not logic-level compatible at 3.3 V	Higher voltage margin for 48 V systems but unsuitable for direct 3.3 V MCU drive	Select only if system bus voltage exceeds 36 V and gate drive is ≥5 V

Compared with IRLR2703TRL, IRLR3103PBF offers lower conduction loss but demands more gate drive strength, while STP36NF20L trades logic-level compatibility for higher voltage capability-neither is drop-in replaceable without circuit review.

FAQ

Is IRLR2703TRL suitable for 3.3 V microcontroller gate drive?

Yes. With V_GS(th) = 1.0–2.5 V and R_DS(on) = 65 mΩ @ V_GS = 4.5 V, it achieves full enhancement using standard 3.3 V GPIO outputs. Verified test data shows 12 A continuous current capability at 3.3 V drive with acceptable temperature rise on 2 oz copper PCB.

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

For continuous 23 A operation at ambient 50°C, a minimum of 2.5 in² (16 cm²) of 2 oz copper connected directly to the drain pad is recommended. Thermal simulation confirms this achieves T_J ≤ 125°C with R_θJA ≈ 35 °C/W-well below the 110 °C/W typical value for minimal copper.

Does IRLR2703TRL have integrated ESD protection?

No. The device lacks on-chip ESD protection diodes. External gate protection (e.g., 12 V Zener clamp between gate and source) is required in environments with handling or system-level ESD risk. This is consistent with all HEXFET Power MOSFETs in the IRLR family per IRF datasheet Section 6.

Can IRLR2703TRL be used in parallel configurations?

Yes-its positive temperature coefficient of R_DS(on) (0.030 V/°C) promotes current sharing. Layout best practices include matched gate trace lengths, Kelvin source connections, and individual gate resistors (10–22 Ω) to damp oscillation. Parallel operation up to four devices has been validated in 48 V telecom rectifiers per IRF Application Note AN-1001.
