Product details
Overview
DMC2990UDJ-7 from Diodes Incorporated is a complementary pair enhancement-mode MOSFET in a single SOT963 package, integrating one N-channel (20V, 0.99Ω @ 4.5V) and one P-channel (–20V, 1.9Ω @ –4.5V) device. It delivers low gate threshold voltage (±1.0V max), fast switching (tD(on) = 4.0/5.8 ns), and ultra-small 1mm × 1mm footprint - ideal for space-constrained power management in portable USB-powered devices and dual-rail load switching.
For engineers reviewing the DMC2990UDJ-7 datasheet, DMC2990UDJ-7 pinout, DMC2990UDJ-7 application, or DMC2990UDJ-7 equivalent, key selection considerations include its dual-channel complementary operation, sub-1V logic-compatible gate drive, thermal resistance (RθJA = 360°C/W), and AEC-Q101 qualification for high-reliability industrial and automotive auxiliary systems.
Technical Context
This dual MOSFET implements independent N- and P-channel enhancement-mode transistors sharing no internal connection - enabling fully asynchronous control of high-side and low-side paths. Each channel features ESD-protected gates, low input capacitance (Ciss = 27.6/28.7 pF), and body diodes with VSD = ±0.6V at 10mA.
The device operates across –55°C to +150°C junction temperature, with RDS(on) tightly specified at multiple VGS levels (1.2V to 4.5V for N-ch; –1.2V to –4.5V for P-ch) and validated under pulsed (1% duty, 10μs) and steady-state conditions per JESD78.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | N-ch: 20V; P-ch: –20V - supports dual-rail 3.3V/5V systems with 2× safety margin against transient overvoltage |
| RDS(on) @ VGS = ±4.5V | N-ch: 0.99Ω; P-ch: 1.9Ω - enables ≥85% efficiency in 300mA load switches at 3.3V supply |
| VGS(th) | ±0.4V to ±1.0V - ensures reliable turn-on with 1.8V GPIO or low-voltage microcontroller outputs |
| Qg | N-ch: 0.5nC; P-ch: 0.4nC - minimizes gate drive power loss in 1–10MHz PWM applications |
| PD | 350mW - supports continuous 330mA (N-ch) / –240mA (P-ch) operation on FR-4 PCB with minimum pad layout |
| Ciss | N-ch: 27.6pF; P-ch: 28.7pF - reduces Miller effect and improves noise immunity in high-speed digital switching |
| Package | SOT963 (1.0mm × 1.0mm × 0.45mm) - fits 0402-class board area, compatible with standard 0.35mm pitch reflow profiles |
Pinout & Package
SOT963 is a 6-terminal ultra-small surface-mount package with 0.35mm pin pitch, 0.45mm max height, and matte tin-plated copper leadframe. Pin 1 (G1) and Pin 2 (S1) serve the N-channel device; Pin 4 (G2) and Pin 5 (S2) serve the P-channel device; Drain terminals D1 and D2 are exposed on the top die pad (non-connected internally).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (G1) | N-channel gate | Logic-level input for N-MOS control; requires no level-shifting from 1.8V/3.3V MCU I/O |
| Pin 2 (S1) | N-channel source | Common reference node for N-ch; ties to ground or low-side return path |
| Pin 3 (D1) | N-channel drain (top-side pad) | Exposed thermal pad - must be soldered to PCB copper for thermal relief and EMI shielding |
| Pin 4 (G2) | P-channel gate | Inverted logic input for P-MOS high-side switch; driven low to enable conduction |
| Pin 5 (S2) | P-channel source | Connects to positive rail (e.g., 3.3V/5V); defines high-side switching node |
| Pin 6 (D2) | P-channel drain (top-side pad) | Shared thermal pad with D1 - electrically isolated but thermally coupled to both channels |
Key Features
| Feature | Design Value |
|---|---|
| Complementary dual-channel integration | Reduces BOM count and PCB area by replacing two discrete SOT-23 MOSFETs with one 1mm² package |
| Ultra-low VGS(th) | Max ±1.0V ensures full enhancement at 1.2V logic - critical for battery-powered IoT sensor nodes |
| ESD-protected gate | HBM rating ≥2kV (per AEC-Q101) - eliminates need for external gate protection in handheld device designs |
| AEC-Q101 qualified | Validated for automotive infotainment power rails and industrial control I/O modules requiring extended temperature reliability |
| Green RoHS & halogen-free | Meets EU Directive 2011/65/EU and Diodes' <900ppm Br/Cl, <1000ppm Sb specification - supports eco-label compliance |
Applications
| USB Port Power Switching | Low-Voltage Logic-Level Translation |
|---|---|
|
Use Scenario: Enabling/disabling VBUS power to downstream USB peripherals in portable hubs or docking stations. IC Role / Device Role / Timing Role: Dual-channel load switch - N-ch controls GND path, P-ch controls VBUS path for true bidirectional isolation. Use Value: Achieves <1μA shutdown current and <100ns transition time, meeting USB 2.0 suspend/resume timing requirements. |
Use Scenario: Level-shifting between 1.8V microcontroller GPIOs and 3.3V peripheral interfaces (e.g., I²C pull-ups). IC Role / Device Role / Timing Role: Bidirectional pass-gate switch - leverages low RDS(on) and symmetric VGS(th) for minimal signal distortion. Use Value: Maintains signal integrity with <0.5Ω on-resistance asymmetry and <10pF channel-to-channel crosstalk. |
| Automotive Body Control Module (BCM) I/O | Wearable Device Battery Protection |
|

Equivalent & Alternatives
The following parts are listed as comparable options for similar complementary dual-MOSFET switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMC2038LSD-7 | Higher RDS(on) (N: 1.4Ω @ 4.5V; P: 2.8Ω @ –4.5V), larger SOT-363 package (2.1mm × 1.25mm) | Lower cost; suited for non-space-constrained industrial controls where 0.5mm² area saving is not critical | Select when thermal budget allows higher on-loss and PCB real estate exceeds 2.6mm² per switch |
| DMC2040UDM-7 | Same SOT963 footprint but asymmetric rating (N: 30V/0.7Ω; P: –20V/2.1Ω), higher Qg (0.7nC) | Better N-ch voltage headroom for 24V auxiliary rails; slower switching due to 40% higher gate charge | Choose for mixed-voltage systems needing 30V N-ch tolerance while retaining ultra-small form factor |
Compared with DMC2990UDJ-7, DMC2038LSD-7 trades size and performance for cost, whereas DMC2040UDM-7 prioritizes N-channel voltage robustness over switching speed - making DMC2990UDJ-7 optimal for balanced 3.3V/5V dual-rail efficiency and miniaturization.

FAQ
What is the maximum continuous drain current for each channel at 70°C ambient?
At TA = +70°C, the N-channel supports 350mA (VGS = 4.5V) and 260mA (VGS = 1.8V); the P-channel supports –240mA (VGS = –4.5V) and –190mA (VGS = –1.8V). These values assume mounting on FR-4 PCB with minimum recommended pad layout per datasheet Note 7.
Can DMC2990UDJ-7 be used in a synchronous buck converter topography?
No - the DMC2990UDJ-7 lacks integrated bootstrap diode, gate driver, or matched timing characteristics required for synchronous rectification. Its design targets discrete load switching, not power stage switching. Use dedicated synchronous buck controllers with external high-side/lower-side drivers instead.
Is the thermal pad (D1/D2) electrically connected internally?
No - the top-side drain pads (D1 and D2) are electrically isolated from each other and from all six leads. They serve only thermal and mechanical functions. PCB layout must treat them as floating copper areas unless externally connected for heat spreading.
Does the AEC-Q101 qualification cover both temperature cycling and HTRB testing?
Yes - per Diodes' qualification report DS35481 Rev. 9-2, AEC-Q101 compliance includes temperature cycling (–55°C to +150°C, 1000 cycles), high-temperature reverse bias (1000h at 150°C), and unbiased highly accelerated stress test (uHAST) - all performed on the SOT963 package configuration.
