Product details

Overview

IRLML2402TR from Infineon Technologies is a 20 V, 1.2 A N-channel enhancement-mode MOSFET in Micro3™ (SOT-23) package, with R_DS(on) = 0.125 Ω at V_GS = 4.5 V and 0.095 Ω at V_GS = 10 V, optimized for low-voltage DC-DC conversion and load switching in space-constrained portable electronics.

For engineers reviewing the IRLML2402TR datasheet, IRLML2402TR pinout, IRLML2402TR application, or IRLML2402TR equivalent, key selection criteria include gate threshold voltage (V_GS(th) = 1.0 V max), ultra-low gate charge (Q_G = 2.1 nC), junction-to-ambient thermal resistance (R_θJA = 270 °C/W), and guaranteed 100% R_DS(on) tested at 4.5 V drive.

Technical Context

This logic-level MOSFET features a planar trench-gate structure enabling fast switching (t_d(on) = 8 ns, t_f = 12 ns) and low conduction loss at 3.3 V/5 V microcontroller gate drive. Its body diode exhibits soft reverse recovery (t_rr = 35 ns) and low forward drop (V_SD = 1.1 V at I_S = 0.93 A).

Designed for unidirectional power path control, it operates within −55 °C to +150 °C junction temperature range, supports pulsed drain current up to 3.2 A, and maintains stable R_DS(on) across temperature (normalized R_DS(on) ≤ 1.5× at T_J = 150 °C).

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	20 V - Maximum blocking voltage compatible with 3.3 V/5 V system rails and USB-powered circuits.
R_DS(on) @ V_GS = 4.5 V	0.125 Ω - Enables <150 mW conduction loss at 1.2 A, critical for battery runtime in portable devices.
I_D (continuous)	1.2 A - Rated current for PCB-mounted operation with standard SOT-23 copper pad layout.
Q_G	2.1 nC - Low gate charge reduces driver power demand and enables efficient PWM at >1 MHz in DC-DC converters.
V_GS(th)	1.0 V max - Ensures full enhancement with 1.8 V/2.5 V logic outputs, supporting modern low-voltage MCUs.
R_θJA	270 °C/W - Thermal performance validated on 1-in² 1-oz copper; requires thermal relief for >0.8 A continuous use.

Pinout & Package

IRLML2402TR uses the Micro3™ (SOT-23 / TO-236AB) package: 3-pin surface-mount, 1.9 mm × 1.3 mm footprint, 0.95 mm height, JEDEC-compliant outline with gull-wing leads.

Pin/Terminal	Circuit Role	Design Meaning
1 (Gate)	Control input	Receives logic-level voltage to modulate channel conductivity; low C_iss = 200 pF minimizes drive energy.
2 (Drain)	Power output	High-side or low-side switch node; connected to load or supply rail; rated for 20 V repetitive blocking.
3 (Source)	Reference return	Common reference for gate drive and load current return; tied to ground or power rail depending on topology.

Key Features

Feature	Design Value
Logic-level gate drive	Guaranteed turn-on at V_GS = 2.5 V, enabling direct interface with 3.3 V and lower I/Os without level-shifting.
Low R_DS(on) at 4.5 V	0.125 Ω ensures minimal I²R loss in high-efficiency buck converter synchronous rectifiers and LED drivers.
Fast switching speed	t_d(on)/t_f = 8 ns/12 ns reduces transition losses in high-frequency (>500 kHz) SMPS designs.
Halogen-free & RoHS-compliant	Meets IPC-1752A material declaration requirements for consumer and industrial end-equipment compliance.

Equivalent & Alternatives

The following parts are listed as comparable options for similar N-channel logic-level MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
DMN2004LK-7	R_DS(on) = 0.115 Ω @ 4.5 V; Q_G = 2.4 nC; V_GS(th) = 0.7 V max	Lower threshold enables marginally better 1.8 V drive but higher gate charge increases switching loss.	Prefer when interfacing with sub-2 V logic; verify gate driver slew rate capability.
SI2302DS-T1-GE3	R_DS(on) = 0.14 Ω @ 4.5 V; Q_G = 1.9 nC; V_GS(th) = 1.2 V max	Higher threshold requires stronger 3.3 V drive; lower Q_G benefits high-frequency PWM.	Choose for cost-sensitive designs where 0.14 Ω R_DS(on) is acceptable and gate drive strength is assured.

Compared with DMN2004LK-7 and SI2302DS-T1-GE3, the IRLML2402TR delivers optimal balance of low R_DS(on), low Q_G, and robust 1.0 V V_GS(th) margin-making it preferred for battery-powered systems requiring both efficiency and drive simplicity.

FAQ

What is the maximum continuous drain current for IRLML2402TR at 25°C ambient?

The maximum continuous drain current is 1.2 A under standard SOT-23 mounting conditions (1-in² 1-oz copper). This rating assumes T_A = 25°C and accounts for R_θJA = 270 °C/W. At elevated ambient temperatures or reduced copper area, derating per the SOA curve is required.

Can IRLML2402TR be used as a high-side switch with 3.3 V gate drive?

No-it is an N-channel MOSFET and requires gate voltage above the source potential to conduct. For high-side switching with 3.3 V logic, a P-channel device (e.g., IRLML6344) or external level-shifting circuit is necessary. Its design intent is low-side or synchronous rectifier use.

Does IRLML2402TR have built-in ESD protection?

Yes-the device includes on-chip gate protection diodes rated for ±2 kV HBM per JESD22-A114. However, handling precautions (grounded workstations, anti-static packaging) remain essential during assembly to prevent latent damage beyond specification limits.

What is the typical reverse recovery time of the body diode?

The body diode reverse recovery time (t_rr) is 35 ns at I_F = 0.93 A, V_R = 16 V, and di/dt = 100 A/μs. This soft recovery characteristic reduces voltage overshoot and EMI in flyback and synchronous buck topologies where the body diode conducts during dead time.
