Product details
Overview
DMN3028L-7 from Diodes Incorporated is an N-channel enhancement-mode MOSFET in SOT23 package, rated for 30V VDSS, 25mΩ RDS(ON) @ 10V VGS, and 6.2A continuous drain current at +25°C - optimized for high-efficiency load switching and DC-DC converter power stages.
For engineers reviewing the DMN3028L-7 datasheet, DMN3028L-7 pinout, DMN3028L-7 application, or DMN3028L-7 equivalent, key selection criteria include low gate threshold (0.8–1.8V), fast switching (tD(ON) = 6.7ns), ESD-protected gate, 1.4W power dissipation on enhanced pad layout, and automotive-grade variant availability (DMN3028LQ).
Technical Context
This MOSFET employs planar trench-gate technology to achieve low RDS(ON) while maintaining robust switching performance: input capacitance Ciss = 680pF and total gate charge Qg = 10.9nC @ 10V enable efficient gate drive in compact power stages.
Its gate threshold voltage range (0.8–1.8V) supports direct interfacing with 3.3V and 5V logic controllers, and the integrated body diode (VSD = 0.7–1.2V @ 1A) enables synchronous rectification and reverse-current blocking in buck converters and load-switch circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 30V - maximum drain-source blocking voltage for 24V rail applications |
| RDS(ON) | 25mΩ @ 10V VGS - enables ≤155mW conduction loss at 6.2A |
| ID (continuous) | 6.2A @ TA = +25°C - supports high-current load switching on standard FR-4 PCBs |
| Qg | 10.9nC @ 10V - determines gate drive energy and switching transition time |
| RθJA | 88°C/W (enhanced pad) - defines thermal rise under 1.4W steady-state power dissipation |
| VGS(TH) | 0.8–1.8V - ensures reliable turn-on with 3.3V microcontroller GPIO |
| Ciss | 680pF @ 15V - impacts high-frequency gate drive loop stability and ringing |
Pinout & Package
Package: SOT23 - surface-mount plastic case, 0.009g weight, UL 94V-0 rated, matte tin-plated copper leadframe, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| 2 (Gate) | Control electrode for channel formation | ESD-protected input requiring <10.9nC charge for full enhancement; sensitive to overvoltage beyond ±20V |
| 3 (Drain) | Main current-carrying terminal | High-side or low-side switch node; handles up to 30V and pulsed 40A; connects to body diode anode |
Key Features
| Feature | Design Value |
|---|---|
| Low RDS(ON) | 25mΩ @ 10V enables <155mW I²R loss at 6.2A - critical for thermally constrained portable power rails |
| Low VGS(TH) | 0.8–1.8V threshold allows direct drive from 3.3V logic without level-shifting circuitry |
| Fast switching | tD(ON) = 6.7ns / tF = 10.4ns supports >1MHz DC-DC operation with minimal dead-time loss |
| ESD-protected gate | HBM rating ≥2kV per JESD22-A114 - eliminates need for external gate protection in board-level ESD zones |
| Green packaging | Halogen- and antimony-free, RoHS 3 compliant - meets automotive and industrial environmental compliance mandates |
Applications

|---|---|
Use Scenario: Power sequencing and fault-isolation in USB-powered peripherals and IoT sensor nodes. IC Role / Device Role: Low-side switch controlling 3.3V/5V supply to downstream ICs.

Use Value: -55°C to +150°C operating range and normalized RDS(ON) stability ensure consistent performance across vehicle thermal cycles. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN3028LQ-7 | Identical electrical specs; qualified to AEC-Q101, PPAP-capable, manufactured in IATF 16949 facility | Required for automotive production; not suitable for cost-sensitive consumer designs | Select when automotive qualification, change control, or long-term supply assurance is mandatory |
| AO3400A | RDS(ON) = 28mΩ @ 10V; higher Qg = 12nC; no ESD protection; same SOT23-3 package | Lacks gate ESD hardening and tighter VGS(TH) distribution - higher risk of gate oxide failure in handling or noisy environments | Acceptable for non-critical, cost-driven industrial prototypes where gate robustness is secondary |
Compared with DMN3028L-7, DMN3028LQ-7 adds automotive qualification without electrical trade-offs, while AO3400A sacrifices gate protection and threshold consistency for marginal BOM cost reduction - making DMN3028L-7 the optimal balance of performance, reliability, and manufacturability for commercial power management.

FAQ
What is the maximum continuous drain current for DMN3028L-7 at +70°C ambient?
The DMN3028L-7 supports 4.9A continuous drain current at TA = +70°C with standard FR-4 PCB mounting (2oz copper, minimum pad layout). This derating reflects thermal limitations governed by RθJA = 146°C/W; using enhanced 1-inch² copper reduces thermal resistance to 88°C/W, sustaining higher current.
Is DMN3028L-7 suitable for 3.3V logic-level gate drive?
Yes - its gate threshold voltage range of 0.8–1.8V ensures full enhancement with 3.3V logic signals. At VGS = 4.5V, RDS(ON) is 28mΩ (vs. 25mΩ at 10V), delivering 5.8A ID with acceptable conduction loss in 3.3V-controlled load switches.
Does DMN3028L-7 include integrated ESD protection on the gate terminal?
Yes - the device features built-in ESD protection on the gate, rated to ≥2kV HBM per JESD22-A114. This eliminates the need for external gate Zener clamps in most board-level ESD environments, simplifying layout and reducing BOM count.
How does the body diode performance impact synchronous rectifier use?
The body diode has VSD = 0.7–1.2V at 1A and exhibits low reverse recovery charge (Qrr not specified but implied by fast tF = 10.4ns), making it viable for low-frequency synchronous rectification. However, for high-frequency (>500kHz) buck converters, an external Schottky may be preferred to minimize forward loss and recovery spikes.
