Product details
Overview
DMN3033LSD-13 from Diodes Incorporated is a dual N-channel enhancement-mode MOSFET in SO-8 package, rated for 30V V(BR)DSS, 20mΩ RDS(ON) @ 10V VGS, and 6.9A continuous drain current at +25°C. It delivers low gate threshold (1–2.1V), fast switching (td(on) = 11ns), and low input capacitance (Ciss = 725pF), enabling high-efficiency synchronous rectification in DC-DC converters.
For engineers reviewing the DMN3033LSD-13 datasheet, DMN3033LSD-13 pinout, DMN3033LSD-13 application, or DMN3033LSD-13 equivalent, key selection criteria include dual-channel RDS(ON) matching, AEC-Q101 qualification, SO-8 thermal performance (RθJA = 62.5°C/W), and gate drive compatibility with 4.5V logic-level controllers.
Technical Context
This dual MOSFET integrates two matched N-channel silicon devices in a single SO-8 footprint, sharing no internal connection between channels-each has independent D/S/G terminals. Its low 13mΩ typical RDS(ON) @ 10V and 22mΩ max @ 4.5V supports efficient operation in 5V- and 12V-input buck converters.
The device employs planar trench-gate technology to balance conduction loss and switching speed: Crss = 92pF and Qgd = 3.2nC minimize Miller-induced shoot-through risk, while fast tr = 7ns and tf = 30ns enable >1MHz switching without excessive gate drive power.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| V(BR)DSS | 30V - Supports input rails up to 24V nominal systems with margin against transients |
| RDS(ON) max | 20mΩ @ VGS = 10V - Enables <140mW conduction loss at 6.9A in high-side switch position |
| ID max | 6.9A @ TA = +25°C - Sustains continuous load current in compact 2W SO-8 thermal envelope |
| VGS(th) | 1–2.1V - Fully enhances with standard 3.3V or 5V microcontroller GPIO outputs |
| Ciss | 725pF - Limits gate drive current requirement to ~1.5mA average at 1MHz switching |
| Qg | 6.4–13nC - Determines total gate charge needed per switching cycle for driver sizing |
| RθJA | 62.5°C/W - Requires minimal PCB copper area (2 oz FR-4) to maintain TJ < 125°C at full load |
Pinout & Package
Package: SO-8, surface-mount, lead-free, RoHS-compliant molded plastic case (UL 94V-0). Moisture sensitivity level 1 per J-STD-020. Weight: 0.072g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| D1 | Drain of Channel 1 | High-side or low-side power path terminal; electrically isolated from D2 |
| S1 | Source of Channel 1 | Return node for Channel 1; tied to gate driver reference if used as low-side switch |
| G1 | Gate of Channel 1 | CMOS-compatible control input; requires 10V for lowest RDS(ON), functional down to 4.5V |
| G2 | Gate of Channel 2 | Independent control input; identical threshold and drive requirements as G1 |
| S2 | Source of Channel 2 | Separate return path for Channel 2; enables dual independent half-bridges or parallel operation |
| D2 | Drain of Channel 2 | Second power switch node; no internal connection to D1 or other pins |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent N-channel topology | Enables space-constrained dual-switch designs (e.g., synchronous buck + OR-ing) without discrete pairing |
| Low RDS(ON) @ 4.5V | 27mΩ max ensures <1.1W conduction loss per channel at 5.8A, critical for 5V-input regulators |
| AEC-Q101 qualified | Validated for automotive power management including infotainment and body electronics |
| Low Crss / Qgd ratio | 92pF Crss and 3.2nC Qgd reduce voltage-dependent Miller plateau duration, improving hard-switching robustness |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual N-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN3025LSD-13 | Lower RDS(ON): 15mΩ @ 10V; higher Ciss: 920pF; same SO-8 package | Better conduction loss but slower switching; less suitable above 500kHz | Select when thermal budget dominates over switching frequency constraints |
| SI6926ADQ-T1-GE3 | Higher V(BR)DSS: 40V; higher RDS(ON): 28mΩ @ 10V; different pinout (G1/D1/S1/S2/G2/D2) | Supports wider input range but requires PCB layout revision due to non-matching pin assignment | Select only when 40V rating is mandatory and layout change is acceptable |
Compared with DMN3033LSD-13, DMN3025LSD-13 trades higher capacitance for lower on-resistance-ideal for thermally constrained 100–300kHz converters-while SI6926ADQ-T1-GE3 offers higher voltage headroom at the cost of layout compatibility and slightly reduced efficiency at 30V operation.

FAQ
Is DMN3033LSD-13 suitable for hot-swap applications?
Yes. Its low 100nA IDSS and ±100nA IGSS ensure minimal leakage during insertion, while the 30V V(BR)DSS provides margin against supply rail overshoot. The SO-8 package's low thermal resistance (62.5°C/W) supports controlled inrush limiting without external thermistors in 12V systems.
What is the maximum safe operating frequency with standard gate drivers?
With a 6Ω series gate resistor and 10V drive, DMN3033LSD-13 achieves reliable switching up to 2MHz. At this frequency, total switching loss remains below 120mW per channel due to its 3.2nC Qgd and 7ns tr, provided PCB layout minimizes gate loop inductance (<2nH).
Does the SO-8 package support hand-soldering for prototype builds?
Yes. The SO-8 footprint is compatible with standard reflow profiles (peak 260°C, 60s above 217°C) and can be hand-soldered using fine-tip irons and flux-cored solder. Diodes' matte tin finish ensures consistent wetting, and the 0.072g mass prevents tombstoning during manual assembly.
How does the AEC-Q101 qualification impact reliability in non-automotive use?
AEC-Q101 testing subjects DMN3033LSD-13 to accelerated temperature cycling, humidity bias, and HTRB stress-extending mean time to failure by 3.2× versus standard industrial-grade MOSFETs. This translates to >10-year field life in 50°C ambient industrial environments, even without automotive thermal cycling demands.
