Product details
Overview
DMN2041UFDB-13 from Diodes Incorporated is a dual N-channel enhancement-mode MOSFET in a U-DFN2020-6 (Type B) package, rated for 20V VDSS, 40mΩ RDS(ON) @ 4.5V VGS, and 4.7A continuous drain current at +25°C - designed for compact, high-efficiency load switching in portable power adaptors and battery-powered systems.
For engineers reviewing the DMN2041UFDB-13 datasheet, DMN2041UFDB-13 pinout, DMN2041UFDB-13 application, or DMN2041UFDB-13 equivalent, key selection criteria include low-profile 0.6mm height, ESD-protected gate, dual-channel integration for space-constrained DC-DC output stages, and validated thermal performance up to +150°C junction temperature.
Technical Context
This dual MOSFET integrates two matched N-channel devices sharing no internal connection between channels - each with independent source, gate, and drain terminals. Its low RDS(ON) at 2.5V and 4.5V gate drive enables efficient operation in 3.3V and 5V logic-controlled power rails.
The device uses a trench-gate process to achieve 713pF input capacitance (Ciss) and 68pF reverse transfer capacitance (Crss), supporting fast switching with 3.6ns turn-on delay and 2.6ns fall time under standard test conditions (VDD = 10V, RG = 1Ω).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 20V - supports input rails up to 18V with 10% margin for transient spikes |
| RDS(ON) @ 4.5V | 40mΩ max - delivers ≤180mW conduction loss at 4.7A, enabling thermally constrained PCB layouts |
| RDS(ON) @ 2.5V | 65mΩ max - ensures functional switching down to 2.5V logic levels without external level shifters |
| Qg @ 4.5V | 8nC - reduces gate drive power and allows use with low-current microcontroller GPIOs |
| TJ Range | –55°C to +150°C - qualified for industrial and extended-temperature portable equipment |
| RθJA | 92°C/W - measured on 1"×1" FR-4 with 2oz copper; defines thermal derating for surface-mount power management |
Pinout & Package
Package: U-DFN2020-6 (Type B), 2.0mm × 2.0mm × 0.6mm profile, NiPdAu-plated terminals, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| D1 | Drain of Channel 1 | High-side or low-side switch node; electrically isolated from D2 |
| S1 | Source of Channel 1 | Return path for Channel 1; tied to system ground or floating rail per layout |
| G1 | Gate of Channel 1 | CMOS-compatible control input; ESD-protected to ±10μA leakage at ±8V |
| D2 | Drain of Channel 2 | Independent power switch node; no internal connection to D1 |
| S2 | Source of Channel 2 | Separate return path; enables dual-rail or redundant load control |
| G2 | Gate of Channel 2 | Independent logic-level input; identical threshold (0.35–1.4V) and drive requirements as G1 |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent N-channel topology | Enables two separate load switches in one 2.0×2.0mm footprint - eliminates discrete pairing and saves ≥40% board area |
| Low RDS(ON) at 2.5V | 65mΩ max ensures reliable turn-on with 2.5V I/O (e.g., USB-C PD controllers, PMIC sequencers) without gate boosting |
| ESD-protected gate | HBM rating >2kV (implied by "ESD Protected Gate" and MIL-STD-202-compliant plating) - reduces handling sensitivity and system-level ESD hardening burden |
| 0.6mm max height | Meets ultra-thin design requirements for slim adapters, wearables, and stacked PCB assemblies |
Applications
| USB-C Power Delivery Adapter | Smartphone Battery Protection Circuit |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual N-channel load switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN2045UFDB-13 | Higher RDS(ON) (55mΩ @ 4.5V), same package and pinout | Lower cost; suitable where 100mW higher conduction loss is acceptable | Select when thermal budget allows 15% higher I²R loss and cost sensitivity outweighs efficiency gain |
| SI2302DS-T1-GE3 | Single-channel SOT-23; 28mΩ @ 4.5V but requires two devices and extra PCB area | No integrated dual-channel timing correlation; higher assembly cost | Choose only if existing SOT-23 footprint reuse is mandatory and board area is unconstrained |
Compared with DMN2041UFDB-13, DMN2045UFDB-13 trades 15mΩ higher on-resistance for lower unit cost, while SI2302DS-T1-GE3 forces duplication of layout and gate drive resources - making the DMN2041UFDB-13 optimal for space- and efficiency-critical dual-switch designs.

FAQ
What is the maximum pulsed drain current rating for DMN2041UFDB-13?
The pulsed drain current (IDM) is rated at 20A for 10μs pulses with 1% duty cycle. This rating assumes proper PCB thermal design (1"×1" FR-4, 2oz copper) and accounts for transient thermal impedance limits. It is not sustainable in DC operation due to power dissipation constraints (PD = 1.4W steady-state).
Does DMN2041UFDB-13 integrate body diodes, and what is their forward voltage?
Yes - each channel includes an intrinsic body diode with typical forward voltage (VSD) of 0.75V at 4.4A and 25°C. The diode exhibits 6.6ns reverse recovery time (tRR) and 1.2nC reverse recovery charge (QRR), enabling efficient synchronous rectification in buck converters when used in appropriate topologies.
Can DMN2041UFDB-13 be used in automotive applications?
No - DMN2041UFDB-13 is not AEC-Q101 qualified. While its operating temperature range (–55°C to +150°C) meets automotive ambient requirements, it lacks PPAP documentation, IATF 16949 manufacturing certification, and stress-test validation required for automotive use. Diodes offers AEC-Q101 variants under different part numbers.
What is the recommended PCB pad layout for U-DFN2020-6 (Type B) package?
The official Diodes-recommended pad layout specifies X1 = 0.600mm, Y1 = 1.000mm, G1 = 0.450mm, and thermal pad dimensions matching the exposed die paddle (D2 = 0.60mm). Use solder mask defined pads and ensure ≥0.15mm soldermask dam between pins to prevent bridging during reflow.
