Product details
Overview
DMC2004DWK-7 from Diodes Incorporated is a complementary pair enhancement-mode MOSFET in a single SOT-363 package, integrating an N-channel (20 V, 540 mA, RDS(on) = 0.4 Ω @ VGS = 4.5 V) and P-channel (–20 V, –430 mA, RDS(on) = 0.7 Ω @ VGS = –4.5 V) device with ultra-low gate threshold voltage (±1.0 V), ESD-protected gates, and low input capacitance for compact load-switching and level-shifting circuits.
For engineers reviewing the DMC2004DWK-7 datasheet, DMC2004DWK-7 pinout, DMC2004DWK-7 application, or DMC2004DWK-7 equivalent, key selection criteria include dual-channel complementary operation, sub-1V VGS(th), thermal resistance of 500 °C/W, and compatibility with 1.8 V logic-level drive in space-constrained portable and battery-powered systems.
Technical Context
This dual MOSFET implements a matched complementary pair topology-Q1 (N-channel) and Q2 (P-channel)-with independent gate control, enabling bidirectional switching, half-bridge configurations, and rail-to-rail signal inversion without external bias networks. Its ±1.0 V gate threshold allows direct interfacing with 1.8 V and 2.5 V microcontrollers.
The device operates across –65 °C to +150 °C, supports fast switching via low Ciss (150 pF / 175 pF), low Coss (25 pF / 30 pF), and exhibits minimal leakage (<1 µA IDSS, ±1 µA IGSS), making it suitable for always-on power management nodes requiring low quiescent current.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | N-ch: 20 V; P-ch: –20 V - supports dual-rail operation up to ±20 V supply, compatible with USB-powered and Li-ion battery systems. |
| RDS(on) | N-ch: 0.4 Ω @ 4.5 V; P-ch: 0.7 Ω @ –4.5 V - enables <100 mW conduction loss at 500 mA, critical for thermally constrained PCB layouts. |
| VGS(th) | N-ch: 0.5–1.0 V; P-ch: –0.5 to –1.0 V - ensures reliable turn-on with 1.8 V GPIO, eliminating need for level shifters in modern MCU interfaces. |
| PD | 250 mW @ TA = 25 °C - defines maximum continuous power dissipation on standard FR-4; derates linearly above 25 °C per 500 °C/W θJA. |
| Ciss | N-ch: 150 pF; P-ch: 175 pF - limits gate drive current demand and propagation delay in high-frequency switching (e.g., PWM dimming, DC-DC sync rectification). |
| Tj/TSTG | –65 to +150 °C - qualifies for extended industrial and automotive under-hood ambient conditions when mounted per JEDEC standards. |
Pinout & Package
SOT-363 (SC-70-6) ultra-small surface-mount package: 2.2 mm × 1.35 mm × 0.95 mm, molded plastic body with UL 94V-0 rating, matte tin-plated Alloy 42 leadframe, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (S1) | N-channel source | Common source node for N-MOS; tied to ground or low-side reference in half-bridge or load-switch topologies. |
| 2 (G1) | N-channel gate | Direct logic-level control input; ESD-protected, requires no external gate resistor for ≤1 MHz switching. |
| 3 (D1) | N-channel drain | Switched output node; connects to load or high-side rail; shares internal die substrate with S2 in complementary pair layout. |
| 4 (D2) | P-channel drain | Shared drain terminal with D1 - enables common-drain (source-follower) configuration or dual-switch parallel routing. |
| 5 (G2) | P-channel gate | Inverted logic control input; driven low to turn on P-MOS; compatible with open-drain or push-pull drivers. |
| 6 (S2) | P-channel source | Connected to positive supply rail in high-side switch applications; forms complementary output pair with S1. |
Key Features
| Feature | Design Value |
|---|---|
| Complementary Pair Integration | Single SOT-363 package contains matched N- and P-channel MOSFETs with symmetrical VGS(th) magnitude, reducing board area by >40% vs. discrete solutions. |
| Low-Voltage Gate Drive | VGS(th) ≤ ±1.0 V enables full enhancement with 1.8 V I/O, eliminating level translators in wearables, IoT sensors, and Bluetooth modules. |
| ESD-Protected Gates | HBM rating ≥2 kV (per JESD22-A114) - protects against handling damage during SMT assembly and field operation without external TVS. |
| Ultra-Low Leakage | IDSS ≤ ±1 µA and IGSS ≤ ±1 µA at rated VDS/VGS - maintains standby current below 2 µA in always-on battery monitoring circuits. |
Applications
| USB Port Power Switching | Li-ion Battery Protection Circuit |
|---|---|
|
Use Scenario: Controlling power delivery to downstream USB peripherals while enforcing overcurrent and reverse-polarity protection. IC Role / Device Role / Timing Role: Dual-MOSFET load switch implementing back-to-back configuration to block reverse current and enable/discharge control. Use Value: Sub-1V VGS(th) ensures full turn-on from 3.3 V USB VBUS; RDS(on) < 0.7 Ω limits voltage drop to <350 mV at 500 mA, preserving bus compliance. |
Use Scenario: Isolating cell terminals during charging/discharging to prevent overvoltage, overdischarge, and short-circuit faults. IC Role / Device Role / Timing Role: Complementary pair used as charge/discharge FETs in integrated protection IC auxiliary paths or discrete BMS designs. Use Value: Matched RDS(on) and thermal tracking between N- and P-channels ensure balanced current sharing and consistent trip timing under fault conditions. |
| Low-Power Sensor Node Power Gating | 1.8 V Logic-Level Signal Inversion |
|
Use Scenario: Enabling/disabling power to MEMS accelerometers, temperature sensors, or RF transceivers during sleep cycles in wireless sensor networks. IC Role / Device Role / Timing Role: High-side (P-ch) and low-side (N-ch) switch pair controlling VDD rail to subsystems with independent gate control. Use Value: Total gate leakage <2 µA preserves battery life over multi-year deployments; SOT-363 footprint fits within 3 mm² PCB area budget. |
Use Scenario: Converting 1.8 V CMOS logic outputs to inverted signals for clock gating, reset synchronization, or interface matching. IC Role / Device Role / Timing Role: Complementary inverter stage with rail-to-rail swing, driven directly from MCU GPIO without pull-ups or level shifters. Use Value: Propagation delay <15 ns (typ.) and low Ciss support >10 MHz toggle rates; matched thresholds minimize dead-time uncertainty. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar complementary MOSFET switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMC2004LSD-7 | Same SOT-363 package but uses logic-level N/P pair with higher RDS(on) (N: 0.65 Ω, P: 1.2 Ω @ ±4.5 V); no ESD protection specified. | Lower cost alternative where ESD immunity is not required and 30% higher conduction loss is acceptable. | Select when BOM cost reduction outweighs gate robustness and thermal margin requirements. |
| DMN2004LFD-7 | Discrete N-channel only (20 V, 540 mA, RDS(on) = 0.4 Ω), same package; lacks integrated P-channel and complementary pairing. | Requires external P-MOS and gate control logic, increasing component count and layout complexity for bidirectional functions. | Choose only if design mandates asymmetrical channel sizing or independent thermal management of each FET. |
Compared with DMC2004LSD-7 and DMN2004LFD-7, the DMC2004DWK-7 uniquely delivers factory-matched complementary characteristics, ESD-hardened gates, and lowest combined RDS(on) in SOT-363-making it optimal for space- and reliability-critical dual-switch applications.

FAQ
What is the maximum continuous drain current for each channel at 85°C?
The N-channel supports 390 mA and the P-channel supports –310 mA at TA = 85°C, per the Absolute Maximum Ratings table. These values reflect thermal derating from the 540 mA/–430 mA ratings at 25°C, based on the device's 500 °C/W junction-to-ambient thermal resistance and FR-4 PCB mounting conditions.
Can DMC2004DWK-7 be used in a back-to-back configuration for AC signal switching?
No - the internal schematic shows shared drain (D1/D2) connection, not isolated channels. The device is designed for DC load switching and level translation, not bidirectional AC blocking. For true back-to-back operation, two discrete MOSFETs with independent drain terminals are required.
Is the SOT-363 package lead-free and RoHS compliant?
Yes - DMC2004DWK-7 uses matte tin-plated Alloy 42 leadframes and is fully RoHS 3 compliant (2015/863/EU), halogen- and antimony-free ("Green"), with no purposely added lead and UL 94V-0 flammability rating per the Mechanical Data section.
Does this part meet AEC-Q101 qualification for automotive use?
No - the datasheet explicitly states that automotive-qualified versions require specific change control (AEC-Q101, PPAP, IATF 16949 manufacturing), and DMC2004DWK-7 is listed as a "NEW PRODUCT" without AEC designation. It is rated for industrial temperature range (–65 °C to +150 °C) but not qualified for automotive stress testing.
