Product details
Overview
DMP2004VK from Diodes Incorporated is a dual P-channel enhancement-mode MOSFET in SOT563 package, rated for -20V V(BR)DSS, 0.9Ω RDS(ON) @ VGS = -4.5V, and -0.53A continuous drain current at +25°C. It serves as a compact, low-threshold load switch or synchronous rectifier in space-constrained portable power systems.
For engineers reviewing the DMP2004VK datasheet, DMP2004VK pinout, DMP2004VK application, or DMP2004VK equivalent, key selection criteria include gate threshold voltage below -1.0V, dual-channel isolation, low input capacitance (175 pF), and compatibility with 2.5V–4.5V logic-level drive in battery-powered DC-DC converters and charging circuits.
Technical Context
This dual MOSFET integrates two independent P-channel devices sharing no internal connection-each with separate source, drain, and gate terminals. Its VGS(th) of -0.5V to -1.0V enables reliable turn-on from low-voltage microcontrollers, while low RDS(ON) and fast switching support high-efficiency buck converter topologies.
The device features integrated ESD protection diodes on each gate, low leakage (<±1.0 µA IGSS), and thermal resistance of 312°C/W (RθJA) on FR-4 PCB. Its SOT563 footprint supports high-density layout in portable adapters where board area and thermal dissipation are tightly constrained.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| V(BR)DSS | -20 V - Maximum drain-source blocking voltage before avalanche conduction |
| RDS(ON) | 0.9 Ω @ VGS = -4.5V - On-resistance enabling <430 mA continuous conduction with <180 mW conduction loss |
| ID (max) | -0.53 A @ TA = +25°C - Continuous drain current rating under standard PCB mounting conditions |
| VGS(th) | -0.5 to -1.0 V - Gate threshold ensures full enhancement with 2.5V logic-level drivers |
| Ciss | 175 pF - Input capacitance limiting gate drive energy and influencing switching speed |
| PD | 400 mW - Total power dissipation limit defining safe operating area on FR-4 board |
| RθJA | 312 °C/W - Junction-to-ambient thermal resistance determining temperature rise per watt |
Pinout & Package
SOT563 is a 6-pin, surface-mount plastic package measuring 2.2 mm × 1.7 mm × 0.5 mm (L × W × H), with lead-free matte tin finish over copper leadframe and moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| G1 | Gate of Q1 | Independent control terminal for first P-channel MOSFET; requires negative bias relative to S1 |
| S1 | Source of Q1 | Reference node for Q1; tied to higher potential in high-side switch configuration |
| D1 | Drain of Q1 | Current output path for Q1; connects to load or inductor in buck stage |
| G2 | Gate of Q2 | Independent control terminal for second P-channel MOSFET; electrically isolated from G1 |
| S2 | Source of Q2 | Reference node for Q2; may be connected separately or paralleled depending on circuit topology |
| D2 | Drain of Q2 | Current output path for Q2; supports dual-switch or redundant load management functions |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent P-channel structure | Enables two separate high-side switches in one 2.2 mm × 1.7 mm footprint without shared source/drain coupling |
| Low gate threshold voltage | VGS(th) ≤ -1.0 V ensures full turn-on with 2.5V I/O rails, eliminating need for charge pumps in portable systems |
| ESD-protected gates | Integrated gate protection diodes withstand ≥2 kV HBM, reducing external ESD component count in handheld designs |
| Low input capacitance | Ciss = 175 pF minimizes gate drive power and propagation delay in 1–2 MHz DC-DC switching |
| Green, RoHS-compliant construction | Halogen- and antimony-free molding compound (<900 ppm Br/Cl, <1000 ppm Sb) meets IPC-1752A environmental reporting requirements |
Applications
| Battery Charging Control | USB Power Delivery Switching |
|---|---|
Use Scenario: Dual-path charging circuit managing primary and backup Li-ion cells in wearables. IC Role / Device Role / Timing Role: High-side load switch controlling charge current direction and isolating cells during fault conditions. Use Value: Low RDS(ON) reduces voltage drop across switch, preserving charging efficiency; dual channels allow independent enable/disable of parallel charging paths. | Use Scenario: USB-C port power routing in portable monitors with dual-input capability (AC adapter + laptop PD). IC Role / Device Role / Timing Role: Bidirectional high-side switch selecting between upstream power sources while maintaining reverse-current blocking. Use Value: VGS(th) < -1.0 V ensures clean turn-on from 3.3V USB-PD controller GPIOs; low leakage (<1 µA) prevents standby current drain. |
| Portable DC-DC Converter | Low-Voltage Load Management |
Use Scenario: Synchronous buck converter in Bluetooth earbud charging case delivering 3.3V/500mA from 7.4V battery. IC Role / Device Role / Timing Role: Upper switch in dual-MOSFET synchronous rectification stage, driven by PWM controller. Use Value: Fast switching (low Ciss/Coss) supports >1.5 MHz operation; low RDS(ON) limits conduction loss to <120 mW at full load. | Use Scenario: Power gating for BLE SoC peripherals (sensor hub, display driver) in smartwatch firmware-controlled sleep modes. IC Role / Device Role / Timing Role: Independent load switch enabling software-selectable power domains with minimal quiescent current. Use Value: Dual-channel isolation allows simultaneous control of two subsystems; low IGSS (<1 µA) extends battery life during deep-sleep states. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual P-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMG2302UK-7 | RDS(ON) = 0.75 Ω @ VGS = -4.5V; VGS(th) = -0.7 to -1.3 V; same SOT563 package | Higher gate threshold spread may require tighter VGS control in low-voltage logic interfaces | Preferred when lower RDS(ON) is critical and gate drive can accommodate wider VGS(th) tolerance |
| AO6401 | RDS(ON) = 0.75 Ω @ VGS = -4.5V; VGS(th) = -0.5 to -1.2 V; SOT23-6 package (larger footprint) | Larger SOT23-6 footprint increases PCB area use but improves thermal dissipation margin | Chosen when thermal performance takes priority over board space and layout density |
Compared with DMG2302UK-7 and AO6401, DMP2004VK offers the tightest VGS(th) upper limit (-1.0 V max) and smallest footprint, making it optimal for ultra-compact 2.5V–3.3V logic-driven load switching where gate drive margin and board area are constrained.

FAQ
What is the maximum continuous drain current for DMP2004VK at +70°C ambient?
At TA = +70°C, the maximum continuous drain current is -0.44 A when VGS = -4.5V and -0.35 A when VGS = -2.5V. This derating reflects junction temperature limits under standard FR-4 PCB mounting with minimum pad layout, where thermal resistance rises with ambient temperature.
Can DMP2004VK be used in a synchronous buck converter's high-side position?
Yes - its -20V V(BR)DSS, low RDS(ON), and fast switching characteristics make it suitable for high-side switching in buck converters up to ~1.5 MHz. Gate drive must provide sufficient negative voltage swing (≥ -4.5V) relative to source, and layout must minimize source inductance to avoid shoot-through risk.
Is the SOT563 package lead-free and RoHS compliant?
Yes - DMP2004VK uses matte tin annealed over copper leadframe and green molding compound meeting EU RoHS Directive 2011/65/EU, with no intentionally added lead, halogens, or antimony. Moisture sensitivity level is rated at Level 1 per J-STD-020.
How are the two MOSFETs internally connected in DMP2004VK?
The two P-channel MOSFETs (Q1 and Q2) are fully isolated - no internal connection exists between their drains, sources, or gates. Pinout confirms independent G1/S1/D1 and G2/S2/D2 terminals, enabling flexible configurations including dual high-side switches or independent load controls.
