Product details
Overview
DMN3012LEG-13 from Diodes Incorporated is a dual-channel 30V N-channel enhancement-mode MOSFET in PowerDI3333-8 package, featuring Q1 with RDS(ON) = 12 mΩ @ VGS = 5 V, ID = 15 A and Q2 with RDS(ON) = 6 mΩ @ VGS = 5 V, ID = 15 A, optimized for synchronous rectification in high-efficiency DC-DC converters.
For engineers reviewing the DMN3012LEG-13 datasheet, DMN3012LEG-13 pinout, DMN3012LEG-13 application, or DMN3012LEG-13 equivalent, this dual MOSFET supports low-loss power conversion in compact point-of-load regulators, battery-powered systems, and USB-C PD power stages where thermal performance and gate drive efficiency are critical.
Technical Context
This device integrates two independent N-channel MOSFETs-Q1 (higher threshold, 1–2.1 V) and Q2 (lower threshold, 0.75–1.15 V)-in a single PowerDI3333-8 thermally enhanced package with exposed die clip. Each channel is rated for 30 V VDSS, ±10 V VGSS, and supports continuous drain currents up to 20 A (Q1) and 20 A (Q2) at TC = 25°C.
Q1 and Q2 exhibit distinct dynamic characteristics: Q1 has Ciss = 650–850 pF and Qg = 4.7–6.1 nC; Q2 has higher capacitance (Ciss = 1137–1480 pF) and charge (Qg = 9.7–12.6 nC), enabling optimized timing control in asymmetric synchronous buck topologies where Q2 serves as the low-side switch.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 30 V - Maximum blocking voltage for both channels; suitable for 24 V input rails and 5 V/3.3 V output stages. |
| RDS(ON) Q1 / Q2 | 12 mΩ / 6 mΩ @ 5 V - Enables <1.8 W conduction loss per channel at 15 A, reducing thermal load in space-constrained PCBs. |
| Qg Q1 / Q2 | 4.7–6.1 nC / 9.7–12.6 nC - Low-to-moderate gate charge enables efficient 1–2 MHz switching with standard gate drivers. |
| tR/tF Q1 / Q2 | 2.7 ns / 3.5 ns rise; 2.3 ns / 2.9 ns fall - Fast edge rates minimize switching transition losses in high-frequency converters. |
| RθJC | 9.5 °C/W - Direct thermal path from junction to case allows >1.4 W continuous dissipation at TC = 70°C without heatsink. |
| UIS Rating | 34 A / 50 A avalanche current - 100% production-tested ruggedness supports reliable operation under inductive load transients. |

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 |
|---|---|---|---|
| DMN3022LSD-13 | Single-channel 30 V, 2.2 mΩ @ 5 V; no integrated dual topology or asymmetric thresholds. | Requires two discrete devices to match DMN3012LEG-13's integration; increases board area and layout complexity. | Select when ultra-low RDS(ON) is prioritized over space savings and gate drive coordination. |
| SiR872DP-T1-GE3 | 30 V dual N-channel with matched 3.5 mΩ RDS(ON); higher Qg (15.5 nC) and larger PowerPAK® 1212-8 package. | Better conduction loss but slower switching and 3× larger footprint; unsuitable for sub-10 mm² designs. | Prefer for high-current (>25 A) industrial supplies where thermal margin outweighs size constraints. |
Compared with DMN3022LSD-13 and SiR872DP-T1-GE3, DMN3012LEG-13 uniquely balances asymmetric RDS(ON), low gate charge, and minimal 3.3 mm × 3.3 mm footprint-enabling compact, high-frequency synchronous converters without sacrificing ruggedness or thermal headroom.

FAQ
What is the maximum continuous drain current rating for each channel at TC = 70°C?
Q1 supports 16 A and Q2 supports 16 A continuous drain current at case temperature 70°C, as specified in the Absolute Maximum Ratings table. These values assume proper PCB thermal design with ≥1 inch² of 2 oz copper connected to the exposed drain pad.
Can DMN3012LEG-13 be used in a synchronous boost converter configuration?
Yes-Q1 and Q2 can be configured as high-side and low-side switches respectively in a synchronous boost topology. Their 30 V VDSS, low RDS(ON), and fast switching enable efficient 12 V-to-24 V conversion up to 500 kHz, provided gate drive voltage exceeds VGS(TH) margins for both channels.
Is the exposed thermal pad electrically isolated or connected internally?
The exposed pad is internally connected to both MOSFET drains and must be soldered to a common PCB copper pour serving as both thermal sink and drain node. It is not electrically isolated and must be routed accordingly to avoid short circuits in multi-rail systems.
Does DMN3012LEG-13 require gate resistors for stable operation?
Gate resistors are recommended: 2 Ω for Q1 and 1 Ω for Q2, based on typical test conditions in the datasheet. These values dampen ringing, control dV/dt, and prevent shoot-through in synchronous topologies while maintaining <7.7 ns tD(ON) and <9.6 ns tD(OFF).
