Product details

Overview

DMN3028L-13 from Diodes Incorporated is an N-channel enhancement-mode MOSFET in SOT23 package, rated for 30V V_DSS, 25mΩ R_DS(ON) @ 10V V_GS, and 6.2A continuous drain current at T_A = +25°C. It features ESD-protected gate, low 1.7Ω gate resistance, and fast switching (t_F = 10.4ns), optimized for compact DC-DC converter high-side switches and load-switching circuits.

For engineers reviewing the DMN3028L-13 datasheet, DMN3028L-13 pinout, DMN3028L-13 application, or DMN3028L-13 equivalent, key selection criteria include verified R_DS(ON) at 4.5V (28mΩ), thermal resistance R_θJA = 88°C/W under enhanced PCB layout, and gate threshold voltage range (0.8–1.8V) enabling direct drive from 3.3V logic.

Technical Context

This MOSFET employs planar silicon process with optimized channel geometry to achieve low on-resistance while maintaining controlled gate charge (Q_g = 7.8nC @ 4.5V). Its low V_GS(TH) and tight distribution support reliable turn-on with standard microcontroller GPIOs.

The device integrates a monolithic body diode with V_SD = 0.7V typical at 1A, and exhibits C_iss = 680pF and C_rss = 74pF at V_DS = 15V - parameters critical for minimizing switching losses and EMI in synchronous buck topologies.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	30V - Maximum blocking voltage before avalanche conduction; supports 24V rail systems with margin.
R_DS(ON) @ 10V	25mΩ - Enables <0.16W conduction loss at 4A, suitable for thermally constrained SOT23 layouts.
R_DS(ON) @ 4.5V	28mΩ - Confirmed operation with 3.3V/5V logic-level drivers without gate boosting.
Q_g @ 4.5V	7.8nC - Low gate charge reduces driver power demand and enables >1MHz switching in DC-DC controllers.
t_F	10.4ns - Fast fall time minimizes overlap loss during hard-switched transitions.
R_θJA (enhanced pad)	88°C/W - Measured with 1-inch² copper pour; defines max 1.4W dissipation at +70°C ambient.
V_GS(TH)	0.8–1.8V - Guaranteed turn-on with 2.5V logic; avoids marginal biasing in low-voltage systems.

Pinout & Package

Package: SOT23 - surface-mount plastic case, 0.9mm × 2.9mm footprint, 0.009g weight, UL 94V-0 rated molding compound, matte tin-plated copper leadframe.

Pin/Terminal	Circuit Role	Design Meaning
1 (Source)	Power return path for drain current; tied to ground or low-side reference	Low-inductance connection essential for stable body-diode commutation and EMI control.
2 (Gate)	Control terminal for channel conduction	ESD-protected input requiring <1.7Ω series resistor to damp ringing in high-dV/dt environments.
3 (Drain)	High-side power output node	Connected to input rail or inductor node; must route with minimal loop area to limit voltage spikes.

Key Features

Feature	Design Value
Low R_DS(ON) at 4.5V	28mΩ enables efficient 3.3V-driven load switching without gate boosters.
ESD-protected gate	Withstands >2kV HBM per JESD22-A114, reducing board-level ESD protection overhead.
Low C_iss/C_rss ratio	680pF / 74pF = 9.2 - improves controllability and reduces Miller-induced shoot-through risk.
Fast t_R/t_F	1.5ns rise / 10.4ns fall - supports clean edge fidelity in 500kHz–2MHz PWM applications.
Green, RoHS-compliant construction	Halogen- and antimony-free (<900ppm Br/Cl, <1000ppm Sb) meets automotive and industrial environmental mandates.

Applications

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
DMN3028LQ-13	AEC-Q101 qualified; identical electrical specs but manufactured in IATF 16949 facility with PPAP support.	Required for automotive production; not needed for commercial/industrial prototypes.	Select when automotive change control, traceability, and qualification documentation are mandatory.
AO3400A	R_DS(ON) = 28mΩ @ 4.5V (same), but higher Q_g = 12nC and no ESD protection on gate.	Higher gate drive loss and external TVS required for robustness in noisy environments.	Choose only if cost sensitivity outweighs gate drive efficiency and system-level ESD design effort.

Compared with DMN3028L-13, DMN3028LQ-13 adds automotive compliance without electrical trade-offs, while AO3400A sacrifices gate robustness and drive efficiency to meet lower BOM cost targets - making DMN3028L-13 optimal for balanced performance, protection, and manufacturability in non-automotive high-reliability designs.

FAQ

Is DMN3028L-13 pin-compatible with other SOT23 N-channel MOSFETs?

Yes - DMN3028L-13 uses standard SOT23 pinout (Drain-Gate-Source on pins 3-2-1), matching industry-standard layout footprints. However, electrical behavior differs significantly from older-generation devices due to lower R_DS(ON), reduced Q_g, and tighter V_GS(TH) distribution; layout review is recommended before drop-in replacement.

What is the maximum continuous drain current at 70°C ambient?

At T_A = +70°C with standard FR-4 PCB (2oz copper, minimum pad), the DMN3028L-13 supports 4.9A continuous drain current. With enhanced thermal pad (1-inch² copper), it delivers 6.2A up to +70°C ambient, confirmed by R_θJA = 88°C/W and P_D = 1.4W ratings.

Does DMN3028L-13 require external gate resistors for stability?

Yes - a 5–10Ω series gate resistor is recommended to damp high-frequency oscillation caused by interaction between its 1.7Ω intrinsic gate resistance and PCB trace inductance. This prevents unintended turn-on during fast dV/dt events and ensures clean switching edges in high-frequency DC-DC applications.

Can DMN3028L-13 be used in reverse-biased configurations (source-to-drain current)?

No - the DMN3028L-13 is an N-channel enhancement-mode MOSFET with an integral body diode oriented source-to-drain. It conducts unidirectionally in diode mode (S→D), but cannot block or regulate reverse current. For bidirectional or reverse-blocking use, a complementary P-channel device or external series diode is required.
