Product details
Overview
DMN3028LQ-13 from Diodes Incorporated is an AEC-Q101 qualified 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. It delivers low gate threshold (0.8–1.8V), fast switching (tD(ON) = 6.7ns), and ESD-protected gate, targeting automotive load switch and DC-DC converter power stages.
For engineers reviewing the DMN3028LQ-13 datasheet, DMN3028LQ-13 pinout, DMN3028LQ-13 application, or DMN3028LQ-13 equivalent, key selection criteria include its AEC-Q101 qualification, 28mΩ RDS(ON) @ 4.5V VGS, thermal resistance of 88°C/W (with copper pad), SOT23 footprint compatibility, and PPAP-capable supply chain for automotive-grade production.
Technical Context
This MOSFET operates as a low-voltage, high-efficiency synchronous rectifier or load switch in 12V automotive systems. Its 0.8–1.8V gate threshold enables direct drive from 3.3V/5V logic controllers, while low Ciss (680pF) and Qg (7.8nC @ 4.5V) support high-frequency PWM operation up to 1MHz in buck converters.
The device integrates gate protection diodes and is characterized across –55°C to +150°C junction temperature. Its RDS(ON) exhibits <15% variation over temperature at VGS = 10V, and body diode forward voltage is specified at 0.7–1.2V @ 1A, supporting bidirectional current handling in regenerative circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 30V - supports 12V automotive rail with 2.5× voltage margin against transients |
| RDS(ON) @ 10V | 25mΩ - enables ≤155mW conduction loss at 6.2A, critical for thermally constrained SOT23 layouts |
| RDS(ON) @ 4.5V | 28mΩ - ensures robust turn-on with standard 5V microcontroller GPIO or PMIC drivers |
| Qg @ 4.5V | 7.8nC - reduces gate drive power and enables <100ns total switching time in 500kHz converters |
| Ciss | 680pF - minimizes Miller effect, improving noise immunity in high-dV/dt environments |
| TJ Range | –55°C to +150°C - validated for under-hood automotive locations per AEC-Q101 stress testing |
Pinout & Package
SOT23-3 package: surface-mount, 3-terminal plastic case with matte tin–annealed copper leadframe; UL 94V-0 rated molding compound; moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |

| S (Source) | Reference return path | Internally tied to substrate; forms body diode cathode; must be routed with low-inductance ground plane |
Key Features
| Feature | Design Value |
|---|---|

|---|---|
|
Use Scenario: Controlling 12V accessory loads (e.g., LED lighting, fans) in BCMs with microcontroller GPIO. IC Role / Device Role / Timing Role: Low-side load switch with fast turn-off (<28ns total fall+delay) to prevent inductive kickback damage. Use Value: 28mΩ RDS(ON) @ 4.5V eliminates external level-shifting, reducing BOM count and PCB area in space-constrained modules. |
Use Scenario: Bidirectional power path control in USB-C PD sink applications requiring reverse-current blocking. IC Role / Device Role / Timing Role: Synchronous rectifier with integrated body diode (VSD = 0.7V @ 1A) enabling efficient 5–20V power routing. Use Value: 680pF Ciss and 74pF Crss minimize cross-conduction risk during dead-time transitions in PD controller ICs. |

Use Scenario: Primary-side synchronous rectifier in isolated 24V-to-5V flyback converters for industrial PLC I/O modules. IC Role / Device Role / Timing Role: Fast-switching power FET with 10.9nC Qg @ 10V enabling >300kHz operation without excessive gate drive loss. Use Value: 88°C/W RθJA (with 1″² copper) allows 1.4W dissipation at +70°C ambient-sufficient for 5A/5V output stage. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN3028LSD-13 | SOT23-6 package with dual N-channel configuration; identical RDS(ON) and VDSS, but shares gate drive between two FETs | Requires matched dual-switching paths (e.g., H-bridge half-bridge); not suitable for single-load switching | Select when needing two coordinated switches in same footprint; avoid for standalone load control |
| NTMFS4C02P | SO-8FL package; 2.2mΩ RDS(ON) @ 10V but 30V rating and 12A ID; higher thermal mass (RθJA = 50°C/W) | Supports higher current and power density but occupies 3× PCB area; not SOT23-compatible | Choose for >8A applications where board space permits larger package and improved thermal performance |
Compared with DMN3028LQ-13, DMN3028LSD-13 trades single-device simplicity for dual-channel integration, while NTMFS4C02P sacrifices compactness for 5× lower on-resistance and superior thermal handling-making each optimal only within distinct layout and current constraints.

FAQ
Is DMN3028LQ-13 suitable for high-frequency switching above 500kHz?
Yes. With 7.8nC total gate charge at 4.5V and 680pF input capacitance, the DMN3028LQ-13 achieves typical turn-on delay of 6.7ns and rise time of 1.5ns, enabling clean switching at 500–1000kHz in properly laid-out PCBs with low-inductance gate drive paths.
What is the maximum continuous drain current at +85°C ambient?
At +85°C ambient with 1″² copper pad (RθJA = 88°C/W), the maximum continuous drain current is 4.2A. This is derived from PD = (TJ(max) − TA) / RθJA = (150 − 85) / 88 ≈ 0.739W, and ID = √(PD/RDS(ON)) = √(0.739 / 0.028) ≈ 4.2A.
Does DMN3028LQ-13 require external gate resistors for automotive EMI compliance?
Yes. While the device supports fast switching, a 10–22Ω series gate resistor is recommended to dampen ringing caused by PCB trace inductance and meet CISPR 25 Class 5 radiated emissions limits in automotive harness environments.
Can DMN3028LQ-13 replace older SOT23 MOSFETs like DMN2004K without layout changes?
No. Although both are SOT23-3, DMN2004K uses different pinout (G-D-S vs. G-S-D). DMN3028LQ-13 follows standard SOT23 pin assignment (G-S-D), so replacement requires verification of PCB silkscreen and net connectivity-not just footprint compatibility.
