Product details
Overview
DMN2053UVTQ from Diodes Incorporated is a dual N-channel enhancement-mode MOSFET in TSOT26 package, rated for 20V VDSS, 35mΩ RDS(ON) @ VGS=4.5V, and 4.6A continuous drain current at +25°C. It delivers low on-resistance with fast switching for high-efficiency DC-DC converters and backlighting power stages.
For engineers reviewing the DMN2053UVTQ datasheet, DMN2053UVTQ pinout, DMN2053UVTQ application, or DMN2053UVTQ equivalent, key selection criteria include gate threshold voltage (0.4–1.0V), input capacitance (369pF), thermal resistance (108°C/W with copper pad), AEC-Q101 qualification, and TSOT26 footprint compatibility.
Technical Context
This dual N-channel MOSFET integrates two matched silicon die in a single TSOT26 package, enabling compact half-bridge or load-switch configurations. Its 1.8V gate drive capability supports modern low-voltage controllers, while 32pF Crss and 3.6nC total gate charge ensure minimal switching losses at MHz-range frequencies.
The device operates across –55°C to +150°C junction temperature, with RDS(ON) increasing only 1.8× from 25°C to 125°C at VGS=4.5V. Its 0.7W steady-state power dissipation (FR-4, 2oz Cu) and 1.1W with thermal pad reflect optimized thermal path design for space-constrained PCBs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 20V - supports 12V rail switching and automotive 12V system transients without avalanche stress |
| RDS(ON) | 35mΩ @ VGS=4.5V - enables <175mW conduction loss at 4.6A, critical for thermally constrained LED drivers |
| Qg | 3.6nC - allows efficient gate driving with <1Ω source impedance, reducing driver IC power consumption |
| Ciss | 369pF - limits Miller-induced shoot-through risk in synchronous buck topologies |
| tF | 3.6ns - ensures clean turn-off edge for EMI-sensitive display power supplies |
| TJ Range | –55°C to +150°C - validated for under-hood automotive lighting and industrial motor control ambient conditions |
Pinout & Package
Package: TSOT26 - ultra-thin surface-mount package (2.9mm × 1.6mm × 0.6mm), 6-pin, lead-free matte tin finish, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| D1, D2 | Drain terminals (Channel 1 & 2) | High-current output nodes; internally isolated; require separate thermal pads or shared ground plane per channel |
| S1, S2 | Source terminals (Channel 1 & 2) | Return paths for respective channels; not internally tied - enables independent high-side or low-side configuration |
| G1, G2 | Gate terminals (Channel 1 & 2) | Independent control inputs; no internal gate coupling - supports asymmetric PWM or phase-shifted operation |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive power management systems requiring PPAP documentation and IATF 16949 manufacturing traceability |
| Low VGS(TH) | 0.4–1.0V threshold enables direct interface with 1.8V/2.5V logic outputs without level-shifting circuitry |
| Halogen- & antimony-free | <900ppm Br, <900ppm Cl, <1000ppm Sb - meets stringent environmental compliance for EU and global automotive OEMs |
| Fast tR/tF | 3.0ns rise / 3.6ns fall time - reduces switching transition losses by >40% vs. legacy 20V MOSFETs in 500kHz–1MHz converters |
Applications

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 |
|---|---|---|---|
| DMN2056UVTQ | Higher RDS(ON) (45mΩ @ 4.5V), same TSOT26 package and AEC-Q101 rating | Lower cost for non-critical efficiency targets; reduced thermal margin in 4.6A continuous use | Select when BOM cost pressure outweighs 0.5W conduction loss increase at full load |
| AOB2018L | Single-channel 20V MOSFET in TSOP-6; 28mΩ @ 4.5V but no dual topology | Requires two devices for dual function; larger board area and higher gate drive complexity | Choose only if channel isolation is unnecessary and layout space permits discrete placement |
Compared with DMN2053UVTQ, DMN2056UVTQ trades 10mΩ higher on-resistance for lower unit cost, while AOB2018L sacrifices integration for marginally better RDS(ON)-making DMN2053UVTQ optimal for space-constrained dual-switch designs demanding AEC-Q101 compliance and sub-1V gate drive.

FAQ
Is DMN2053UVTQ pin-compatible with other TSOT26 dual MOSFETs?
No - DMN2053UVTQ uses a proprietary pin assignment: Pin 1=G1, Pin 2=S1, Pin 3=D1, Pin 4=D2, Pin 5=S2, Pin 6=G2. This differs from industry-standard dual-MOSFET pinouts like the "GSD-GSD" layout. Layout must follow Diodes' recommended pad dimensions and thermal relief patterns to avoid solder bridging or thermal imbalance.
What is the maximum safe operating frequency for DMN2053UVTQ in a synchronous buck converter?
Based on its 3.6nC Qg, 32pF Crss, and 3.6ns tF, DMN2053UVTQ supports reliable operation up to 2MHz in well-designed layouts with <1Ω gate drive impedance and proper PCB grounding. Efficiency peaks between 500kHz–1.2MHz; above 1.5MHz, switching losses dominate due to fixed Crss-related charge.
Does DMN2053UVTQ support 1.8V logic-level gate drive across temperature?
Yes - VGS(TH) remains ≤1.0V up to +125°C (Figure 8), and RDS(ON) stays ≤56mΩ @ VGS=1.8V, ID=2.0A across –55°C to +150°C (Figure 7). This enables direct connection to 1.8V microcontroller GPIOs without level shifters in automotive and industrial environments.
How does the TSOT26 package affect thermal performance compared to SO-8?
TSOT26 delivers 108°C/W θJA with a 1-inch² copper pad - 35% higher than typical SO-8 (70°C/W) - but occupies 75% less board area. Its thin profile (0.6mm) suits ultra-low-profile applications like smartphone bezel lighting, though it requires strict adherence to Diodes' pad layout guidelines to achieve rated thermal performance.
