Product details
Overview
DMN2053UVTQ-13 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 TA=+25°C. It delivers low conduction loss and fast switching for compact DC-DC converters in automotive display backlighting systems.
For engineers reviewing the DMN2053UVTQ-13 datasheet, DMN2053UVTQ-13 pinout, DMN2053UVTQ-13 application, or DMN2053UVTQ-13 equivalent, key selection criteria include RDS(ON) at low gate drive (2.5V/1.8V), AEC-Q101 qualification, TSOT26 thermal performance (RθJA = 108°C/W with copper pad), and body diode recovery (tRR = 6.0ns).
Technical Context
This dual N-channel MOSFET integrates two matched silicon die in a single TSOT26 package, sharing no internal connection between channels-each operates independently with isolated source, gate, and drain terminals. Its 20V rating targets 12V rail and USB-PD auxiliary power stages, while low 35mΩ on-resistance at 4.5V enables high-efficiency synchronous rectification.
The device features 369pF input capacitance (Ciss) and 3.6nC total gate charge (Qg), supporting >1MHz switching in buck converters. Gate threshold voltage (0.4–1.0V) ensures reliable turn-on with logic-level drivers, and the 150°C max junction temperature supports under-hood automotive operation.

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-13 | RDS(ON) = 22mΩ @ 4.5V (lower), but higher Ciss = 520pF and Qg = 5.2nC | Better conduction efficiency but requires stronger gate driver; less suitable for 2.5V logic control | Prefer when gate drive strength ≥10mA available and priority is <0.5W conduction loss |
| AOB2034L | SO-8 package (larger footprint), RDS(ON) = 28mΩ @ 4.5V, non-AEC-Q101, RθJA = 62°C/W | Higher thermal performance but incompatible with space-constrained automotive PCBs | Choose only for industrial prototypes where board area >25mm² is available and AEC-Q101 not required |
Compared with DMN2053UVTQ-13, DMN2056UVTQ-13 trades gate drive simplicity for lower conduction loss, while AOB2034L sacrifices miniaturization and automotive qualification for superior thermal dissipation in non-automotive settings.

FAQ
Is DMN2053UVTQ-13 suitable for hot-swap applications?
Yes - its 20V VDSS, 22A pulsed drain current (IDM), and low 35mΩ RDS(ON) support controlled inrush limiting in 12V hot-swap circuits. The device's 1.4A continuous body diode current (IS) and 6.0ns reverse recovery time further reduce stress during transient events, provided external gate resistors limit dV/dt during turn-on.
What is the maximum PCB copper area needed to achieve the 1.1W power dissipation rating?
To achieve the 1.1W power dissipation (PD) rating with RθJA = 108°C/W, a minimum 1-inch square (25.4mm × 25.4mm) of 2oz copper is required per the datasheet Note 6. Smaller pads yield higher thermal resistance - e.g., standard FR-4 layout with minimal copper gives RθJA = 173°C/W and PD = 0.7W.
Does the TSOT26 package support reflow soldering per J-STD-020?
Yes - the TSOT26 package has moisture sensitivity level 1 (MSL-1), meaning it can be stored indefinitely at ≤30°C/85% RH and withstand standard Pb-free reflow profiles (peak 260°C) without baking. The matte tin annealed finish ensures reliable solder wetting per MIL-STD-202, Method 208.
Can both channels be paralleled to increase current handling?
No - the two channels are electrically isolated with separate source, gate, and drain terminals; they share no internal connection. Paralleling would require external wiring of all corresponding terminals (S1=S2, G1=G2, D1=D2), introducing imbalance due to trace inductance and thermal gradients. For higher current, use a single-channel part with lower RDS(ON) like DMN2056UVTQ-13.
