Product details

Overview

DMN2046UVT from Diodes Incorporated is a dual N-channel enhancement-mode MOSFET in TSOT26 package, rated for 20V V_DSS, 90mΩ R_DS(ON) @ 4.5V V_GS, and 2.6A continuous drain current at +25°C - optimized for high-efficiency DC-DC converters and LED backlighting power stages.

For engineers reviewing the DMN2046UVT datasheet, DMN2046UVT pinout, DMN2046UVT application, or DMN2046UVT equivalent, key selection criteria include low gate charge (3.6nC @ 4.5V), fast switching (t_R = 8.2ns), ESD-protected gate, and dual-channel integration enabling compact synchronous buck or load-switch topologies.

Technical Context

This dual MOSFET integrates two matched N-channel devices with independent source, gate, and drain terminals per channel. Each channel features a gate threshold voltage of 0.4–1.4V and supports logic-level drive down to 2.5V, enabling direct interface with 3.3V microcontrollers and PMICs.

Thermal performance is defined by R_θJA = 213°C/W on FR-4 (2oz Cu, min pad) and 133°C/W with enhanced copper area. The device includes integrated body diodes with V_SD = 0.7–1.2V and supports bidirectional current flow in synchronous rectification applications.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	20V - Maximum drain-source blocking voltage for 3.3V/5V rail switching without derating.
R_DS(ON)	90mΩ @ V_GS = 4.5V - Enables <150mW conduction loss at 1.3A per channel in compact space-constrained designs.
Q_g	3.6nC @ V_GS = 4.5V - Low gate charge reduces driver power and enables >1MHz PWM operation with minimal switching loss.
C_iss	278pF - Low input capacitance minimizes Miller effect and improves noise immunity in high-dV/dt environments.
I_D (max)	2.6A @ T_A = +25°C - Sustains continuous output current for 2A-class buck converters with margin for thermal headroom.
T_J range	−55°C to +150°C - Qualified for industrial and extended-temperature automotive auxiliary systems.

Pinout & Package

Package: TSOT26 - 6-pin thermally enhanced surface-mount package with exposed drain pad; footprint compatible with JEDEC MO-220 variant, 2.9mm × 1.6mm × 0.95mm height, moisture sensitivity level 1.

Pin/Terminal	Circuit Role	Design Meaning
D1	Drain of Channel 1	High-side or low-side switch node; electrically tied to exposed thermal pad for heat dissipation.
S1	Source of Channel 1	Return path for Channel 1; used as reference for gate drive and current sensing in half-bridge configurations.
G1	Gate of Channel 1	Logic-level control input; ESD-protected with ±10µA leakage up to ±12V.
D2	Drain of Channel 2	Independent high-side or low-side switch node; isolated from D1 except through shared thermal pad.
S2	Source of Channel 2	Independent return path for Channel 2; enables dual independent switching or complementary operation.
G2	Gate of Channel 2	Separate logic-level control input; fully decoupled from G1 to prevent crosstalk in high-speed switching.

Key Features

Feature	Design Value
Low R_DS(ON) at 2.5V drive	130mΩ - Enables efficient operation directly from 2.5V GPIO or low-voltage PMIC outputs.
Fast switching speed	t_R = 8.2ns, t_F = 27ns - Supports high-frequency (>1MHz) DC-DC conversion with reduced dead-time losses.
ESD-protected gate	HBM >2kV - Eliminates need for external gate protection in standard industrial PCB layouts.
Green, RoHS-compliant construction	Halogen- and antimony-free, <900ppm Br+Cl - Meets IEC 61249-2-21 and automotive environmental compliance requirements.

Applications

LED Backlight Driver

Synchronous Buck Converter

Use Scenario: Driving parallel white LED strings in LCD panel backlight units with PWM dimming.

IC Role / Device Role / Timing Role: Dual-channel low-side switch controlling LED cathode current; one channel for main string, second for auxiliary or dimming path.

Use Value: 90mΩ R_DS(ON) limits conduction loss to <160mW per channel at 1.3A, reducing thermal load on thin-film PCBs.

Use Scenario: High-efficiency 5V-to-3.3V point-of-load converter in portable instrumentation.

IC Role / Device Role / Timing Role: Integrated high-side and low-side switch pair replacing discrete MOSFETs in synchronous buck topology.

Use Value: Matched channel characteristics and low Q_g enable precise duty-cycle control and <85% peak efficiency at 1A load.

USB-C Power Delivery Load Switch

Industrial Sensor Power Sequencing

Use Scenario: Enabling/disabling 5V/9V/15V rails in USB-C PD sink applications with inrush current limiting.

IC Role / Device Role / Timing Role: Dual independent load switches managing VBUS and auxiliary power domains with separate enable control.

Use Value: Independent gate control allows staggered turn-on and prevents system-wide voltage droop during hot-plug events.

Use Scenario: Controlled power-up sequencing of analog front-end, MCU, and communication ICs in factory automation sensors.

IC Role / Device Role / Timing Role: Dual-channel power gate managing isolated 3.3V and 5V subsystems with independent reset coordination.

Use Value: −55°C to +150°C operating range ensures reliable startup and hold-off in unheated outdoor enclosures.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
DMN2045UVT-7	R_DS(ON) = 70mΩ @ 4.5V (lower), but higher Q_g = 5.2nC and larger TSOT26 footprint with different pinout (G1/S1/D1/G2/S2/D2 → G1/D1/S1/G2/D2/S2).	Higher conduction efficiency but slower switching; unsuitable for >500kHz designs requiring tight timing control.	Select when lowest R_DS(ON) dominates over switching loss and layout allows pinout rework.
AOB2046L	Same 20V rating and dual N-channel function, but in TSOP-6 package (larger, 3.05mm × 1.65mm); R_DS(ON) = 85mΩ @ 4.5V, Q_g = 4.1nC.	Higher thermal resistance (R_θJA = 230°C/W) limits power density; not suitable for ultra-thin consumer modules.	Prefer when legacy TSOP-6 footprint compatibility is required and board space permits larger outline.

Compared with DMN2046UVT, DMN2045UVT offers lower conduction loss but sacrifices switching speed and pinout compatibility, while AOB2046L trades thermal performance for mechanical backward compatibility - making DMN2046UVT optimal for new designs prioritizing size, speed, and thermal efficiency in space-constrained DC-DC stages.

FAQ

Is DMN2046UVT suitable for automotive applications?

No - DMN2046UVT is not AEC-Q101 qualified. While it operates from −55°C to +150°C and meets RoHS/"Green" standards, Diodes explicitly states that automotive-grade versions require PPAP capability and IATF 16949 manufacturing; this part is intended for industrial and commercial use only.

What is the maximum safe operating frequency for DMN2046UVT in a synchronous buck converter?

Based on t_R = 8.2ns and t_F = 27ns, plus Q_g = 3.6nC, the device supports stable operation up to 2MHz with appropriate gate driver strength (≥2A peak) and PCB layout minimizing parasitic inductance; above 1.5MHz, layout optimization becomes critical to avoid shoot-through.

Can DMN2046UVT be used in a high-side switch configuration?

Yes - each channel supports high-side switching when driven with a bootstrap or charge-pump gate driver delivering ≥4.5V above its source potential; the 12V V_GSS rating and 20V V_DSS allow safe operation with 5V or 12V gate drive referenced to floating source nodes.

Does the TSOT26 package require special soldering profile considerations?

Yes - TSOT26 has an exposed drain pad that must be soldered to a thermal pad with ≥4 thermal vias (0.3mm diameter) to achieve specified R_θJA; reflow profile must follow J-STD-020 Level 1 (peak ≤245°C), and stencil aperture for the thermal pad should be 70–80% open area to prevent voiding and ensure mechanical reliability.
