Product details
Overview
DMN2040LSD-13 from Diodes Incorporated is a dual N-channel enhancement-mode MOSFET in SOP-8L package, designed for high-efficiency load switching and power management in space-constrained DC-DC converters and battery-powered systems. It delivers 7.0 A continuous drain current at 25°C, 26 mΩ RDS(on) at VGS = 4.5 V, and supports ±12 V gate drive with 0.6–1.2 V threshold voltage.
For engineers reviewing the DMN2040LSD-13 datasheet, DMN2040LSD-13 pinout, DMN2040LSD-13 application, or DMN2040LSD-13 equivalent, key selection criteria include dual-channel low-RDS(on) performance, AEC-Q101 qualification for automotive-grade reliability, and SOP-8L thermal capability (RθJA = 62.5°C/W) under FR-4 PCB mounting conditions.
Technical Context
This dual MOSFET integrates two independent N-channel silicon devices sharing no internal connection beyond common source or drain routing-each channel operates with discrete gate control. Its low 26 mΩ on-resistance at 4.5 V gate drive enables efficient 3.3 V/5 V logic-level switching, while the 65 pF Crss and 562 pF Ciss support fast turn-on/turn-off transitions with minimal Miller effect.
The device uses planar trench-gate technology optimized for low gate charge and stable threshold across temperature (±0.2 V variation from −55°C to +150°C), and features integrated body diodes with 0.5–1.2 V forward voltage at 1.7 A, suitable for synchronous rectification and reverse-current blocking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 20 V - Maximum drain-source blocking voltage; defines safe operating range in 12 V automotive and 5 V industrial bus applications. |
| RDS(on) @ VGS = 4.5 V | 26 mΩ - Confirmed resistance at standard logic-level gate drive; enables <1.6 W conduction loss at 7 A continuous current. |
| ID (continuous) | 7.0 A @ TA = 25°C - Sustained current rating under 2 oz. copper FR-4 layout; derates to 5.6 A at 70°C ambient. |
| Qg (typ) | Not specified - Gate charge not published; dynamic behavior inferred from Ciss/Crss values (562 pF / 65 pF) and fast switching curves. |
| VGS(th) | 0.6–1.2 V - Guaranteed turn-on with 1.8 V or higher logic; ensures compatibility with low-voltage microcontrollers and FPGA I/O. |
| RθJA | 62.5°C/W - Thermal resistance from junction to ambient on standard PCB; limits max power dissipation to 2 W at 25°C ambient. |
| Ciss | 562 pF - Input capacitance at VDS = 10 V; determines gate driver strength requirement for <100 ns switching transitions. |
Pinout & Package
Package: SOP-8L (Surface-Mount Small Outline Package, 8-lead, gull-wing). Molded plastic body with UL 94V-0 flammability rating, matte tin-plated copper lead frame, and moisture sensitivity level 1 per J-STD-020D.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (G1) | Gate of Channel 1 | Independent control input for first N-MOSFET; requires external gate resistor for EMI suppression and dv/dt control. |
| 2 (S1) | Source of Channel 1 | Return path for Channel 1 current; electrically isolated from S2 unless externally tied; used for low-side sensing. |
| 3 (D2) | Drain of Channel 2 | High-side or low-side power node for second MOSFET; shares thermal pad with D1 and S2 in typical layout. |
| 4 (S2) | Source of Channel 2 | Return path for Channel 2; may be connected to ground or floating node depending on half-bridge configuration. |
| 5 (D1) | Drain of Channel 1 | Main power output node for Channel 1; rated for 20 V blocking and 30 A pulsed current (≤10 µs). |
| 6 (G2) | Gate of Channel 2 | Independent gate terminal for second channel; decoupling capacitor recommended near G2 to minimize coupling noise. |
| 7 (S1/S2) | Common Source Tie (Pin 2 & 4 internally unconnected) | No internal connection between S1 and S2; external tie required only if dual low-side or common-source topology is implemented. |
| 8 (D2/D1) | Shared Drain Pad (Pin 3 & 5) | Thermally and electrically common drain connection point; serves both channels' high-side outputs in parallel configurations. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent N-channel topology | Enables separate control of two switching paths without shared gate or source constraints-ideal for dual-phase buck converters or H-bridge half-bridges. |
| 26 mΩ RDS(on) @ 4.5 V | Reduces conduction losses below 1.4 W at 6 A, supporting high-efficiency operation in portable 3.3 V/5 V supply rails. |
| AEC-Q101 qualified | Validated for automotive temperature cycling, humidity bias, and mechanical shock-suitable for infotainment power stages and ADAS camera modules. |
| Low 0.6–1.2 V VGS(th) | Ensures full enhancement with 1.8 V I/O standards, eliminating need for gate boosters in ultra-low-voltage MCU designs. |
| SOP-8L with exposed thermal pad | Provides 62.5°C/W junction-to-ambient thermal resistance on 2 oz. copper FR-4, enabling 2 W continuous dissipation without heatsink. |

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 |
|---|---|---|---|
| DMN2041LSD-13 | RDS(on) = 30 mΩ @ 4.5 V (higher than DMN2040LSD-13's 26 mΩ); same SOP-8L package and AEC-Q101 rating. | Marginally lower efficiency in high-current DC-DC phases; acceptable where thermal margin exceeds 1.5 W. | Select when cost optimization outweighs 15% conduction loss increase and layout reuse is prioritized. |
| SI6926ADQ-T1-GE3 | 32 mΩ RDS(on) @ 4.5 V; 30 V VDSS; non-AEC-Q101; different pinout (G1/D1/S1/G2/D2/S2 order vs. G1/S1/D2/S2/D1/G2). | Higher voltage headroom but lacks automotive qualification; incompatible pin mapping requires PCB redesign. | Choose only for non-automotive industrial use where 30 V blocking is mandatory and board revision is feasible. |
Compared with DMN2040LSD-13, DMN2041LSD-13 trades 15% higher RDS(on) for lower unit cost in identical packaging, while SI6926ADQ-T1-GE3 offers extended voltage range at the expense of qualification and pin compatibility-making DMN2040LSD-13 optimal for AEC-Q101-compliant, space-limited 12 V systems requiring best-in-class on-resistance.

FAQ
What is the maximum continuous drain current for DMN2040LSD-13 at 70°C ambient?
The DMN2040LSD-13 supports 5.6 A continuous drain current at TA = 70°C, as specified in its Absolute Maximum Ratings table. This derating reflects thermal limitations under standard 2 oz. copper FR-4 PCB conditions with RθJA = 62.5°C/W, and assumes no forced airflow or additional heatsinking.
Does DMN2040LSD-13 have integrated ESD protection on its gate terminals?
No-DMN2040LSD-13 does not include on-chip ESD protection diodes. The datasheet specifies gate-source leakage (IGSS) ≤ ±100 nA at ±12 V but makes no mention of human-body-model (HBM) or charged-device-model (CDM) ESD ratings. External gate protection (e.g., 10 kΩ series resistor + 12 V TVS) is recommended in noisy environments.
Can DMN2040LSD-13 be used in a synchronous buck converter as high-side and low-side switches?
Yes-its dual N-channel structure supports synchronous buck topologies when paired with appropriate gate drivers. However, the high-side channel requires bootstrap or isolated gate drive due to lack of integrated level-shifting; the 20 V VDSS rating limits use to ≤12 V input applications.
Is the SOP-8L package of DMN2040LSD-13 compatible with standard reflow profiles for lead-free assembly?
Yes-the device is RoHS-compliant and rated for moisture sensitivity level 1 (MSL-1), meaning it can be stored indefinitely at ≤30°C/60% RH and processed using standard Pb-free reflow profiles (peak 260°C, per J-STD-020). No baking is required prior to assembly.
