Product details
Overview
DMN2040LTS-13 from Diodes Incorporated is a dual N-channel enhancement-mode MOSFET in TSSOP-8L package, rated for 20 V VDSS, 6.7 A continuous drain current at 25°C, and 19 mΩ typical RDS(on) at VGS = 4.5 V. It features low gate threshold (0.5–1.2 V), fast switching (tD(on) = 5.2 ns), and AEC-Q101 qualification for automotive power management circuits.
For engineers reviewing the DMN2040LTS-13 datasheet, DMN2040LTS-13 pinout, DMN2040LTS-13 application, or DMN2040LTS-13 equivalent, key selection criteria include dual-channel RDS(on) matching, thermal resistance (RθJA = 140 °C/W), gate charge (Qg = 5.2 nC), and AEC-Q101 reliability validation for under-hood DC-DC and load-switching designs.
Technical Context
This dual MOSFET integrates two matched N-channel silicon devices in a single TSSOP-8L thermally enhanced package, enabling compact half-bridge or dual-load configurations without cross-conduction risk. Its low 1.2 V max VGS(th) ensures reliable turn-on with 3.3 V logic-level drivers, while the 570 pF Ciss and 75 pF Crss support high-frequency PWM operation up to 1 MHz.
The device uses planar trench-gate technology optimized for low RDS(on) vs. temperature stability-RDS(on) increases only 1.6× from −55°C to +150°C at VGS = 4.5 V-and includes integrated body diodes with 0.7–1.2 V forward voltage at 1.7 A, suitable for synchronous rectification and bidirectional current paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 20 V - Supports 12 V automotive rail systems with 67% headroom against transients. |
| RDS(on) @ VGS = 4.5 V | 19 mΩ typ - Enables ≤120 mW conduction loss per channel at 6 A DC load. |
| Qg | 5.2 nC - Allows efficient drive with <10 mA average gate current at 1 MHz PWM. |
| tD(on) | 5.2 ns - Minimizes shoot-through risk in half-bridge topologies with tight dead-time control. |
| RθJA | 140 °C/W - Limits junction rise to ≤125°C at 0.89 W dissipation on FR-4 PCB with minimum pad layout. |
| AEC-Q101 Qualified | Validated for automotive temperature cycling (−55°C to +150°C) and HTRB stress - required for engine control and ADAS power stages. |
Pinout & Package
Package: TSSOP-8L (3.0 mm × 4.4 mm × 1.0 mm), molded green compound, UL 94V-0 rated, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | Source 1 (S1) | Common source node for Channel 1; tied internally to Pin 4 in standard layout. |
| 4 | Drain 1 (D1) | High-side output terminal for Channel 1; electrically isolated from D2. |
| 5, 6, 7 | Source 2 (S2) | Common source node for Channel 2; independent of S1 for dual-load isolation. |
| 8 | Drain 2 (D2) | High-side output terminal for Channel 2; enables independent switching of two loads. |
| G1 | Gate 1 | Control input for Channel 1; requires separate gate resistor to prevent oscillation. |
| G2 | Gate 2 | Control input for Channel 2; fully independent timing and drive capability. |
Key Features
| Feature | Design Value |
|---|---|
| Low RDS(on) matching | ≤10% inter-channel variation ensures balanced current sharing in parallel load control. |
| Logic-level gate drive | VGS(th) max = 1.2 V - compatible with 3.3 V microcontrollers without level-shifting circuitry. |
| Fast switching with low Qgd | Qgd = 1.25 nC - reduces Miller plateau time and improves EMI profile in high-dV/dt environments. |
| Integrated body diode | VSD = 0.7 V @ 1.7 A - supports freewheeling in buck converters and reverse-current blocking in USB PD power paths. |
Applications
| Automotive LED Headlamp Driver | USB-C Power Delivery Load Switch |
|---|---|
Use Scenario: Dual-channel current regulation for high-beam/low-beam LED strings in modern vehicle lighting modules. IC Role / Device Role / Timing Role: Dual N-MOSFET switch controlling independent LED channels with PWM dimming and short-circuit protection.

IC Role / Device Role / Timing Role: Dual-channel high-side switch with integrated current sensing feedback via RDS(on) monitoring. Use Value: 6.7 A rating handles 2 A inductive loads with 3× surge margin; low leakage (<1 μA IDSS) prevents false triggering during sleep mode. | Use Scenario: Secondary-side synchronous rectification in 12 V input, 3.3/5 V output isolated flyback converters for telecom power supplies. IC Role / Device Role / Timing Role: Dual N-MOSFET replacing Schottky diodes to reduce conduction loss and improve efficiency above 75% load. Use Value: 19 mΩ RDS(on) cuts rectifier loss by >60% vs. 40 V/3 A Schottky; fast tf = 6.1 ns suppresses ringing during zero-cross transitions. |
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 |
|---|---|---|---|
| DMN2041LTS-13 | RDS(on) = 24 mΩ @ 4.5 V (vs. 19 mΩ); same package and pinout. | Slightly higher conduction loss limits use in high-current (>5 A) continuous duty cycles. | Select when cost sensitivity outweighs 260 mW/channel efficiency penalty at full load. |
| SI6926ADQ-T1-GE3 | Higher VDSS = 30 V; RDS(on) = 22 mΩ @ 4.5 V; Qg = 7.5 nC (vs. 5.2 nC). | Better transient tolerance but slower switching and higher gate drive demand. | Prefer for 24 V industrial systems where 30 V rating justifies added switching loss and driver complexity. |
Compared with DMN2040LTS-13, DMN2041LTS-13 trades lower cost for reduced efficiency at high current, while SI6926ADQ-T1-GE3 offers wider voltage margin at the expense of increased gate charge and thermal overhead-making DMN2040LTS-13 optimal for space-constrained 12 V automotive and USB-C power switches requiring minimal drive strength and best-in-class RDS(on).

FAQ
What is the maximum continuous drain current per channel at 100°C ambient?
At TA = 100°C, the DMN2040LTS-13 delivers 3.2 A per channel (derated from 4.9 A at 70°C using RθJA = 140 °C/W and TJ(max) = 150°C). This assumes FR-4 PCB with minimum recommended copper pad area per datasheet Figure 11 transient thermal curve.
Does the device support bidirectional current flow between drains?
No-drains D1 and D2 are electrically isolated. Current flows only from drain to source in each channel. However, the integrated body diodes allow reverse current from source to drain (S→D), enabling freewheeling in inductive loads when the MOSFET is off.
Can DMN2040LTS-13 be used in linear (analog) regulator applications?
It is not recommended: the device lacks guaranteed Safe Operating Area (SOA) curves for linear mode, and its RDS(on) variation with temperature (±15% over −55°C to +125°C) introduces instability in precision analog biasing. Use dedicated LDOs or linear regulators instead.
Is the TSSOP-8L package lead-free and RoHS-compliant?
Yes-the DMN2040LTS-13 is lead-free by design and RoHS-compliant per EU Directive 2011/65/EU, with no intentionally added lead and "Green" molding compound meeting UL 94V-0 flammability rating. Moisture sensitivity level is rated at Level 1 per J-STD-020.
