Product details
Overview
DMN2300UFB-7B from Diodes Incorporated is a 20V N-channel enhancement-mode MOSFET in X1-DFN1006-3 package, optimized as a low-profile load switch with RDS(ON) = 175 mΩ @ VGS = 4.5V, ID = 1.32 A, and gate threshold voltage of 0.45–0.95 V, deployed in space-constrained portable power rails and battery protection circuits.
For engineers reviewing the DMN2300UFB-7B datasheet, DMN2300UFB-7B pinout, DMN2300UFB-7B application, or DMN2300UFB-7B equivalent, key selection criteria include ultra-small footprint (0.6 mm²), low VGS(TH) enabling 1.8 V logic compatibility, fast switching (tF = 10.62 ns), thermal resistance of 104 °C/W on enhanced pad layout, and ESD-protected gate.
Technical Context
This MOSFET employs planar silicon process technology to achieve low RDS(ON) while maintaining robust gate oxide integrity and sub-1 V threshold control. Its channel design supports stable conduction down to 1.8 V drive, with dynamic parameters-Qg = 0.89 nC, Qgd = 0.16 nC, and Ciss = 67.6 pF-optimized for minimal switching loss in high-frequency load switching.
The device integrates an intrinsic body diode with VSD = 0.7–1.2 V at IS = 300 mA and exhibits normalized RDS(ON) drift of ≤1.6× from –55°C to +150°C, confirming suitability for ambient-variable industrial and consumer environments without derating penalties.

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 |
|---|---|---|---|
| DMN2016LFG-7 | RDS(ON) = 120 mΩ @ VGS = 4.5 V; higher ID = 2.2 A; same X1-DFN1006-3 package | Supports higher continuous current but requires larger gate drive energy (Qg = 1.2 nC) | Select when >1.5 A load current or lower conduction loss is prioritized over gate drive simplicity |
| AO3414 | RDS(ON) = 52 mΩ @ VGS = 4.5 V; SOT-23 package; VGS(TH) = 0.7–1.4 V; no ESD protection | Larger footprint (2.9 mm²), higher threshold, no integrated ESD clamp | Choose only if board area is unconstrained and external ESD protection is already implemented |
Compared with DMN2300UFB-7B, DMN2016LFG-7 delivers lower RDS(ON) at cost of increased Qg, while AO3414 trades compactness and ESD robustness for raw on-resistance-making DMN2300UFB-7B optimal for space- and reliability-critical 1.8 V–3.3 V systems.

FAQ
What is the maximum continuous drain current for DMN2300UFB-7B at +85°C ambient?
At TA = +85°C with 2 oz copper FR-4 PCB and minimum recommended pad layout, the continuous drain current is 0.94 A. This rating reflects thermal derating due to reduced heat dissipation capacity at elevated ambient temperature, and assumes steady-state conduction without pulse duty cycling.
Does DMN2300UFB-7B require external gate resistors for typical load-switch operation?
No external gate resistor is required for basic on/off control at frequencies ≤100 kHz. The device's low Qg (0.89 nC) and internal gate resistance (~68.5 Ω) provide inherent damping; however, a 10–47 Ω series resistor is recommended when driving from high-speed MCU GPIO to suppress ringing in layouts with >5 cm trace length.
Can DMN2300UFB-7B be used in reverse-current blocking configurations?
Yes-the body diode is oriented source-to-drain, so placing the MOSFET as a high-side switch (source tied to input rail, drain to load) blocks reverse current flow when off. With VGS = 0 V, IDSS ≤ 1 µA at 20 V ensures negligible backfeed, making it suitable for bidirectional isolation in battery backup paths.
Is the X1-DFN1006-3 package compatible with standard reflow profiles for lead-free soldering?
Yes-X1-DFN1006-3 is qualified for IPC/JEDEC J-STD-020 Level 1 moisture sensitivity and supports standard Pb-free reflow profiles (peak 260°C, 60 sec max above 217°C). The NiPdAu finish ensures wetting reliability, and the 0.5 mm profile avoids tombstoning when using recommended stencil aperture (0.12 mm thickness, 0.15 mm × 0.15 mm opening).
