Product details
Overview
DMC2004VK-7 from Diodes Incorporated is a complementary pair enhancement-mode MOSFET in a single SOT563 package, integrating an N-channel (20 V, 670 mA) and P-channel (−20 V, −530 mA) device with ultra-low gate threshold voltage (VGS(TH) < 1 V for both channels), low RDS(ON) (0.4 Ω @ 4.5 V for Q1; 0.7 Ω @ −4.5 V for Q2), and ESD-protected gates. It enables compact bidirectional switching in space-constrained DC-DC converters and load switches.
For engineers reviewing the DMC2004VK-7 datasheet, DMC2004VK-7 pinout, DMC2004VK-7 application, or DMC2004VK-7 equivalent, key selection criteria include dual-channel complementary operation in one ultra-small footprint, sub-1 V gate drive compatibility with 1.8 V logic, and validated thermal performance on FR-4 with 2 oz copper.
Technical Context
This dual MOSFET implements independent N- and P-channel enhancement-mode transistors sharing a common source configuration per channel (S1/S2 tied internally to respective sources), enabling half-bridge or complementary switching without external interconnects. Its low input capacitance (Ciss = 150 pF / 175 pF) and fast switching speed support high-frequency operation up to 1 MHz in synchronous buck regulators.
The device operates across −55 °C to +150 °C with JEDEC-qualified reliability and features ESD protection on all gates (HBM > 2 kV). Thermal resistance is 281 °C/W (steady-state, minimal pad) and 129 °C/W (with 1-inch² copper plate), allowing 450 mW continuous dissipation under standard layout conditions.

Equivalent & Alternatives
The following parts are listed as comparable options for similar complementary MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMC2400UV-7 | Higher RDS(ON) (0.65 Ω N / 1.0 Ω P @ ±4.5 V); same SOT563 package | Lower drive strength; suited for ≤300 mA loads where cost optimization is critical | Select when thermal budget allows higher conduction loss and gate drive voltage ≥2.5 V |
| DMN2004LK-7 | Single N-channel only (20 V, 670 mA); same RDS(ON), same package | Cannot replace complementary function; requires external P-FET for bidirectional control | Choose only if design uses separate gate control for each channel and needs matched N-FET performance |
Compared with DMC2400UV-7 and DMN2004LK-7, the DMC2004VK-7 uniquely delivers matched low-threshold complementary switching in one package-enabling true 1.8 V–driven half-bridge operation without layout compromise or BOM expansion.

FAQ
What is the maximum continuous drain current for each channel at +85°C?
The N-channel (Q1) supports 480 mA and the P-channel (Q2) supports −380 mA at TA = +85°C with standard FR-4 PCB layout (2 oz copper, minimum pad). These values reflect derating due to thermal resistance (RθJA = 281 °C/W) and ensure junction temperature remains below 150°C under steady-state operation.
Is DMC2004VK-7 qualified for automotive use?
The base DMC2004VK-7 is not AEC-Q101 qualified, but Diodes offers the automotive-grade DMC2004VK-Q variant-identical die and package, manufactured in IATF 16949-certified facilities, with full PPAP documentation and AEC-Q101 stress testing. Customers requiring automotive qualification must specify the Q-suffix part number.
Can the N- and P-channel sources be connected externally?
No-S1 (N-source) and S2 (P-source) are physically separate terminals with no internal connection. They are electrically isolated and must be routed independently on PCB. This allows flexible topologies including high-side N-FET + low-side P-FET configurations without shared source constraints.
What is the recommended gate resistor value for 1 MHz switching?
A 10 Ω series gate resistor is recommended for 1 MHz operation with 3.3 V drive, balancing switching speed (trise/tfall ≈ 15 ns) and ringing suppression. Lower values (≤5 Ω) increase EMI risk; higher values (>22 Ω) degrade efficiency due to extended transition times and increased switching loss.
