Product details

Overview

DMN3066L-13 from Diodes Incorporated is an N-channel enhancement-mode MOSFET in SOT23 package, rated for 30V V_DSS, 67mΩ R_DS(ON) at V_GS = 4.5V, and 3.6A continuous drain current at T_A = +25°C. It features low gate threshold (0.5–1.5V), fast switching (t_D(ON) = 5.7ns), and ESD-protected gate - optimized for compact, high-efficiency load-switching in space-constrained DC/DC and battery-powered systems.

For engineers reviewing the DMN3066L-13 datasheet, DMN3066L-13 pinout, DMN3066L-13 application, or DMN3066L-13 equivalent, key selection criteria include R_DS(ON) at low V_GS (2.5–4.5V), thermal resistance (R_θJA = 154°C/W on FR-4), gate charge (Q_g = 4.1nC), and SOT23 footprint compatibility with automated assembly.

Technical Context

This MOSFET operates as a single N-channel power switch with enhancement-mode gate control, requiring positive V_GS to conduct. Its low 0.5–1.5V V_GS(TH) enables direct drive from 3.3V or even 2.5V logic, while its 4.1nC total gate charge and 19ns rise time support efficient high-frequency switching up to several hundred kHz in discrete load-switch and hot-swap circuits.

The device integrates an intrinsic body diode (V_SD = 0.7–1.2V at I_S = 0.6A) and is characterized for operation across –55°C to +150°C junction temperature. Thermal performance is specified for two PCB conditions: 154°C/W (minimum pad) and 94°C/W (1-inch² copper), enabling accurate power dissipation modeling in real layouts.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	30V - Maximum blocking voltage before avalanche conduction; suitable for 24V rail and 12V automotive auxiliary loads.
R_DS(ON)	67mΩ @ V_GS = 4.5V - On-resistance determines conduction loss; 67mΩ yields <150mW loss at 1.8A, critical for thermally constrained designs.
I_D (continuous)	3.6A @ T_A = +25°C - Steady-state current capability under standard test board; derates to 2.9A at +85°C ambient.
Q_g	4.1nC - Total gate charge defines driver strength requirement; enables low-power GPIO or small gate drivers to achieve fast turn-on.
t_D(ON)/t_R	5.7ns / 19ns - Fast switching minimizes transition losses in PWM-controlled load switches operating above 100kHz.
V_GS(TH)	0.5–1.5V - Low threshold ensures reliable turn-on from 3.3V microcontrollers without level-shifting circuitry.
P_D	0.81W (FR-4, min pad) - Power dissipation limit defines maximum safe continuous power under standard PCB layout.

Pinout & Package

Package: SOT23 - surface-mount plastic package with 3 terminals, 0.008g mass, UL 94V-0 rated molding compound, matte tin–annealed copper leadframe, moisture sensitivity level 1.

Pin/Terminal	Circuit Role	Design Meaning
Drain (D)	High-side power path output	Connected to load; carries full switched current; electrically tied to die substrate in SOT23.

Key Features

Feature	Design Value
Low V_GS(TH)	0.5–1.5V enables direct interface with 2.5V/3.3V MCUs and PMICs without gate drivers.
Fast switching speed	5.7ns turn-on delay + 19ns rise time reduces energy loss during transitions in high-duty-cycle applications.
ESD-protected gate	HBM-rated ≥2kV protects against handling damage during SMT assembly and board handling.
Green, RoHS-compliant construction	Lead-free, halogen-free, antimony-free per Diodes' "Green" definition (<900ppm Br/Cl, <1000ppm Sb).
Thermally optimized SOT23 layout	Specified R_θJA values (94°C/W and 154°C/W) allow precise thermal design using standard PCB copper area rules.

Applications

Use Value: 67mΩ R_DS(ON) limits voltage drop to <120mV at 1.8A, preserving PD compliance margins; low V_GS(TH) allows direct control from USB PD controller GPIO.

Use Scenario: Isolates main Li-ion battery from system during overvoltage, overtemperature, or fault conditions.

IC Role / Device Role: Primary protection FET in battery management IC (BMS) secondary protection chain.

Use Value: 30V rating exceeds 4S Li-ion stack (16.8V max); fast 5.7ns t_D(ON) supports rapid fault shutdown within 10µs response window.

IoT Sensor Node Power Gating

Use Scenario: Powers down BLE/Wi-Fi modules and sensors during deep-sleep cycles to extend battery life.

IC Role / Device Role: Low-quiescent-load power switch controlled by MCU wake-up timer or interrupt.

Use Value: 1.0µA I_DSS leakage at 30V ensures <30nA standby current per switch; SOT23 footprint saves board area in miniaturized nodes.

Use Scenario: Drives 24V solenoids, relays, or indicator LEDs in programmable logic controller output modules.

IC Role / Device Role: Discrete high-side switch replacing integrated smart power switches where cost and simplicity are prioritized.

Equivalent & Alternatives

The following parts are listed as comparable options for similar N-channel load-switch applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
DMN2053U-7	20V V_DSS, 32mΩ @ 4.5V, SOT23 - lower voltage rating but lower R_DS(ON).	Restricted to ≤12V systems; unsuitable for 24V industrial or USB PD applications.	Select only when V_IN ≤12V and ultra-low R_DS(ON) is critical; verify gate drive margin at 2.5V.
AO3400	30V V_DSS, 42mΩ @ 4.5V, SOT23 - lower R_DS(ON) but no specified ESD rating or AEC-Q200 alignment.	Lacks documented ESD protection; not qualified for automotive or high-reliability industrial use.	Prefer for cost-sensitive consumer applications where ESD robustness is secondary; avoid in medical or automotive BOMs.

Compared with DMN2053U-7 and AO3400, DMN3066L-13 uniquely balances 30V capability, 67mΩ on-resistance at 4.5V, guaranteed ESD protection, and full RoHS/Green compliance - making it the most robust choice for industrial and portable 24V-compatible load-switch designs requiring long-term supply stability.

FAQ

Is DMN3066L-13 suitable for 24V automotive accessory circuits?

Yes - its 30V V_DSS rating provides 6V headroom above nominal 24V systems, and its –55°C to +150°C operating range meets extended temperature requirements for under-hood and cabin-mounted modules. While not AEC-Q101 qualified out-of-box, Diodes offers PPAP-capable versions upon request for automotive change-controlled programs.

What is the recommended PCB layout for thermal performance?

For 0.81W power dissipation, use the minimum recommended SOT23 pad layout per Diodes' outline drawing: 2.0mm × 0.8mm copper pad for Drain, with 1.35mm X-dimension and 2.9mm Y-dimension. Adding thermal vias under the Drain pad to inner-layer copper planes improves R_θJA toward the 94°C/W specification.

Does DMN3066L-13 have a body diode, and what is its forward voltage?

Yes - it includes an integrated parasitic body diode with typical V_SD = 0.7V at I_S = 0.6A and V_GS = 0V. This diode conducts from Source to Drain and is rated for 3.0A pulsed current, supporting reverse-current blocking and freewheeling in certain topologies.

Can DMN3066L-13 be driven directly from a 3.3V GPIO without a gate driver?

Yes - its V_GS(TH) range (0.5–1.5V) and R_DS(ON) = 67mΩ at V_GS = 4.5V ensure strong enhancement at 3.3V (R_DS(ON) ≈ 85–95mΩ). With Q_g = 4.1nC, even weak GPIOs (e.g., 4mA drive) achieve ~1µs switching, sufficient for most load-switch timing requirements.
