Product details
Overview
DMN2990UDJQ-7 from Diodes Incorporated is a dual N-channel enhancement-mode MOSFET in SOT963 package, rated for 20V VDSS, 0.99Ω RDS(ON) at 4.5V VGS, and 450mA ID at +25°C - designed for ultra-compact power switching in space-constrained DC-DC converters and analog switches.
For engineers reviewing the DMN2990UDJQ-7 datasheet, DMN2990UDJQ-7 pinout, DMN2990UDJQ-7 application, or DMN2990UDJQ-7 equivalent, this device supports low-voltage logic-level drive (VGS(TH) ≤ 1.0V), delivers fast switching (tF = 6.4ns), and operates reliably across –55°C to +150°C with AEC-Q101 qualification.
Technical Context
This dual MOSFET integrates two matched N-channel channels in a single ultra-small 1mm × 1mm SOT963 package, sharing no internal connection between channels - enabling independent control of two low-side switching paths. Its 1.0V max gate threshold allows direct interfacing with 1.2V/1.8V logic families without level shifting.
The device exhibits low dynamic parameters: Ciss = 27.6pF, Qg = 0.5nC, and tD(ON) = 4.0ns, supporting high-frequency operation up to several MHz in buck converter topologies while maintaining low conduction loss at sub-500mA loads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 20V - supports input rails up to 18V in industrial and automotive auxiliary power domains |
| RDS(ON) @ 4.5V | 0.99Ω max - enables <100mW conduction loss at 320mA, critical for thermally limited PCB layouts |
| VGS(TH) max | 1.0V - ensures full enhancement with 1.2V CMOS outputs, eliminating need for gate boosters |
| ID @ 25°C | 450mA continuous - sufficient for LED drivers, sensor biasing, and low-power load switching |
| Ciss | 27.6pF - minimizes gate drive power and improves EMI behavior in high-dV/dt environments |
| TJ range | –55°C to +150°C - qualified per AEC-Q101, suitable for under-hood and industrial control applications |
| PD | 350mW - defined on FR-4 with minimum pad layout, aligning with 0.45mm profile thermal constraints |
Pinout & Package
SOT963 is a 6-pin ultra-thin leadless package (1.0mm × 1.0mm × 0.45mm max height) with exposed thermal pad not connected internally; terminals are matte tin annealed over copper leadframe, solderable per MIL-STD-202.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| G1 | Gate of Channel 1 | Independent control input for first N-MOSFET; referenced to S1 |
| S1 | Source of Channel 1 | Low-side return path for Channel 1; electrically isolated from S2 |
| D1 | Drain of Channel 1 | Switched output node for Channel 1; no internal connection to D2 |
| G2 | Gate of Channel 2 | Independent control input for second N-MOSFET; referenced to S2 |
| S2 | Source of Channel 2 | Low-side return path for Channel 2; electrically isolated from S1 |
| D2 | Drain of Channel 2 | Switched output node for Channel 2; no internal connection to D1 |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent N-channel topology | Enables two separate low-side switches in one footprint - reduces board area by >60% vs. discrete SOT-23 pairs |
| Ultra-low VGS(TH) | 1.0V max threshold ensures reliable turn-on with 1.2V/1.8V I/O, avoiding gate undervoltage failure in battery-powered systems |
| Low RDS(ON) at 1.5V VGS | 2.4Ω at 1.5V enables functional switching even during brown-out conditions down to 1.5V supply |
| ESD-protected gate | Withstands ≥2kV HBM - eliminates need for external gate protection in handheld and portable designs |
| AEC-Q101 qualified | Validated for automotive temperature cycling, humidity, and mechanical stress - supports PPAP documentation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-side switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN2053UVTQ-7 | Higher RDS(ON) (1.4Ω @ 4.5V), same SOT963, VDSS = 20V | Lower efficiency at >200mA; better suited for cost-sensitive non-automotive use | Select when thermal margin exceeds 100°C/W and AEC-Q101 is not required |
| FDMA1023NZ | Single-channel, WDFN-6 (1.5mm × 2.0mm), RDS(ON) = 0.75Ω @ 4.5V, VDSS = 20V | Requires two devices for dual function; larger footprint but higher current rating (600mA) | Select when higher current per channel (>450mA) or separate thermal pads are needed |
Compared with DMN2990UDJQ-7, DMN2053UVTQ-7 trades lower cost for reduced efficiency and no AEC-Q101 validation, while FDMA1023NZ offers higher per-channel current at the expense of board area and dual-function integration.

FAQ
What is the maximum continuous drain current per channel at +70°C ambient?
At TA = +70°C, the DMN2990UDJQ-7 supports 350mA continuous drain current per channel when VGS = 4.5V, as specified in the Absolute Maximum Ratings table. This derating reflects thermal limitations of the 350mW power dissipation capability in the SOT963 package under typical PCB conditions.
Does the SOT963 package include an exposed thermal pad?
No - the SOT963 package used for DMN2990UDJQ-7 has no internal thermal pad connection. Thermal performance relies entirely on conduction through the six perimeter terminals and PCB copper area, with RθJA = 360°C/W measured on FR-4 with minimum recommended pad layout.
Can both channels be paralleled to increase current capacity?
No - the DMN2990UDJQ-7 channels are electrically isolated with separate source, drain, and gate terminals. Paralleling would require external wiring that introduces mismatched parasitics and uncontrolled current sharing; Diodes does not characterize or recommend this configuration.
Is the body diode forward voltage specified, and what is its relevance?
Yes - the source-drain diode forward voltage is specified as VSD = 0.6V (typ) at IS = 150mA and VGS = 0V. This parameter matters in bidirectional current paths or freewheeling applications, such as synchronous rectification in low-duty-cycle boost converters where reverse conduction occurs.
