Product details
Overview
DMN2027LK3-13 from Diodes Incorporated is a 20V N-channel enhancement-mode MOSFET in TO252-3L package, featuring RDS(on) = 21 mΩ @ VGS = 10 V, 17.0 A continuous drain current at TA = 25°C, and fast switching with tr = 22.3 ns and Qg = 9.1 nC - deployed in DC-DC converters and LED backlighting power stages.
For engineers reviewing the DMN2027LK3-13 datasheet, DMN2027LK3-13 pinout, DMN2027LK3-13 application, or DMN2027LK3-13 equivalent, key selection criteria include low-voltage gate drive compatibility (RDS(on) = 27 mΩ @ VGS = 4.5 V), thermal performance on 25 mm × 25 mm 1 oz FR4 (RθJA = 58.4 °C/W), and body diode recovery (trr = 121 ns, Qrr = 583 nC).
Technical Context
This MOSFET employs planar trench-gate technology to achieve low RDS(on) while maintaining controlled gate charge (Qg = 9.1 nC @ VGS = 4.5 V) and fast turn-on/turn-off times (tD(on) = 5.4 ns, tD(off) = 18.7 ns). Its VGS(th) range of 0.6–2.0 V enables reliable logic-level and PWM-driven operation.
The integrated body diode exhibits VSD = 0.89 V @ IS = 10 A and trr = 121 ns under standardized conditions (dI/dt = 100 A/µs), supporting synchronous rectification and freewheeling in buck and boost topologies without external diode supplementation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 20 V - supports input rails up to 16 V with 20 % margin for transient spikes in portable power systems. |
| RDS(on) | 21 mΩ @ VGS = 10 V - delivers ≤ 3.6 W conduction loss at 17 A, enabling high-efficiency 12 V input DC-DC stages. |
| ID (continuous) | 17.0 A @ TA = 25°C - sustains full-load current on standard PCB layouts without forced airflow. |
| Qg | 9.1 nC @ VGS = 4.5 V - reduces gate driver power demand and enables efficient 500 kHz–1 MHz switching in compact converters. |
| tr/tf | 22.3 ns / 12.6 ns - minimizes switching transition losses and EMI generation in high-frequency power stages. |
| VGS(th) | 0.6–2.0 V - ensures robust turn-on with 3.3 V or 5 V logic-level gate drivers, eliminating need for level-shifting circuitry. |
| RθJA | 58.4 °C/W (25 mm × 25 mm 1 oz FR4) - defines thermal derating to 11.6 A at TA = 70°C for unheatsinked designs. |
Pinout & Package
Package: TO252-3L (DPAK), surface-mount, molded plastic case with UL 94V-0 rating, matte tin-plated copper leadframe, and moisture sensitivity level 1 per J-STD-020D.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| D (Drain) | Main power output terminal | Connected to PCB copper pour for thermal dissipation; electrically tied to source of upstream switch in half-bridge configurations. |
| S (Source) | Reference node for gate control and current sensing | Provides return path for load current and serves as common reference for gate driver IC feedback loops. |
| G (Gate) | Control input for channel conduction | Receives low-impedance PWM signal; requires <10 Ω series resistance to damp ringing due to Ciss = 857 pF. |
Key Features
| Feature | Design Value |
|---|---|
| Low RDS(on) at 4.5 V gate drive | 27 mΩ enables direct interfacing with 3.3 V microcontrollers and PMICs without gate boosting. |
| Fast body diode recovery | trr = 121 ns and Qrr = 583 nC reduce reverse recovery losses in synchronous rectifier applications. |
| Optimized gate charge profile | Qgd/Qg = 35 % ensures stable Miller plateau behavior and mitigates shoot-through risk in bridge circuits. |
| RoHS-compliant "Green" construction | Halogen-free, antimony-free molding compound meets EU environmental compliance requirements for industrial and consumer products. |
Applications
| LED Backlighting | DC-DC Buck Converter |
|---|---|
|
Use Scenario: Driving parallel strings of white LEDs in LCD monitor backlight units with PWM dimming at 200 Hz–20 kHz. IC Role / Device Role: Low-side switching element controlling current through LED string via constant-current regulator feedback loop. Use Value: 21 mΩ RDS(on) limits conduction loss to <0.4 W at 15 A, reducing thermal stress on compact PCBs without heatsinks. |
Use Scenario: High-efficiency 12 V-to-3.3 V point-of-load converter delivering up to 15 A to FPGA or SoC core rails. IC Role / Device Role: Synchronous rectifier in buck topology, replacing Schottky diode to improve efficiency by 3–5 % at full load. Use Value: Fast tf = 12.6 ns and low Qrr minimize dead-time losses and voltage overshoot during body-diode commutation. |
| Power Management IC Interface | USB-C Power Delivery Sink |
|
Use Scenario: Load switch controlled by PMIC enable signals in multi-rail embedded systems requiring inrush current limiting. IC Role / Device Role: Single-pole, single-throw power switch placed between battery and subsystem rail (e.g., display, audio codec). Use Value: VGS(th) = 0.6–2.0 V guarantees turn-on with 1.8 V or 3.3 V enable outputs, eliminating external level shifters. |
Use Scenario: Input protection and load switching in USB-C PD sink designs accepting up to 20 V input with programmable current limits. IC Role / Device Role: Reverse-polarity and overcurrent protection switch placed before PD controller and buck converter input. Use Value: 20 V VDSS and 46.8 A pulsed ID support safe operation across full USB-C PD voltage range (5–20 V) with margin. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN2026LK3-13 | RDS(on) = 18 mΩ @ VGS = 10 V; higher ID = 18.5 A; identical TO252-3L package and pinout. | Better conduction efficiency in thermally constrained 12 V input converters where <0.5 W loss reduction matters. | Select when board layout allows same footprint and thermal margin is tight; verify gate drive capability for lower VGS(th) min. |
| SI2302DS-T1-GE3 | RDS(on) = 35 mΩ @ VGS = 4.5 V; SOT-23 package; lower ID = 2.6 A; significantly smaller size and cost. | Suitable for <2 A loads in space-constrained portable devices but not drop-in for 15 A applications. | Choose only for low-current (<3 A), low-power auxiliary rails where TO252 thermal mass is unnecessary. |
Compared with DMN2027LK3-13, DMN2026LK3-13 offers lower conduction loss at equal gate voltage but requires validation of gate drive strength due to tighter VGS(th) distribution, while SI2302DS-T1-GE3 trades current capacity and thermal robustness for miniaturization - making it unsuitable for primary power stage replacement.

FAQ
Is DMN2027LK3-13 suitable for 3.3 V gate drive?
Yes. With VGS(th) as low as 0.6 V and RDS(on) = 27 mΩ @ VGS = 4.5 V, the device fully enhances using standard 3.3 V logic outputs. Gate charge Qg = 5.2 nC @ VGS = 2.5 V confirms strong sub-4.5 V drive capability, though conduction loss increases ~28 % versus 10 V drive.
What is the maximum safe operating temperature for continuous use?
The junction temperature must not exceed 150°C. At TA = 70°C on a 25 mm × 25 mm 1 oz FR4 board, the device supports 11.6 A continuous drain current (derated from 17.0 A at 25°C) based on RθJA = 58.4 °C/W and PD = 2.14 W max. Thermal design must ensure ambient + (I2R × RθJA) ≤ 150°C.
Does DMN2027LK3-13 include an integrated body diode?
Yes. It features a monolithic parasitic body diode with VSD = 0.89 V @ IS = 10 A and reverse recovery time trr = 121 ns. This diode supports freewheeling and synchronous rectification but is not rated for avalanche energy; repetitive operation must stay within SOA limits shown in the datasheet.
Can DMN2027LK3-13 replace older DMP2027LK3 variants?
No. DMN2027LK3-13 is a distinct part with updated process and characterization. While both share TO252-3L packaging and similar RDS(on), the DMN version specifies tighter VGS(th) (0.6–2.0 V vs. older 1.0–2.5 V), improved Qrr, and revised thermal ratings. Cross-referencing requires full electrical and thermal validation per application.
