Product details
Overview
DMN2004DWK-7 from Diodes Incorporated is a dual N-channel enhancement-mode MOSFET in SOT363 package, rated for 20V VDSS, 0.55Ω RDS(ON) at 4.5V VGS, and 540mA continuous drain current at +25°C. It delivers low gate threshold (0.5–1.0V), fast switching (tD(ON) = 4.1ns), and ultra-low input capacitance (Ciss = 36pF typ), enabling high-efficiency load switching in space-constrained portable power rails.
For engineers reviewing the DMN2004DWK-7 datasheet, DMN2004DWK-7 pinout, DMN2004DWK-7 application, or DMN2004DWK-7 equivalent, key selection criteria include dual-channel RDS(ON) matching, AEC-Q101 qualification status, thermal resistance (RθJA = 625°C/W), and gate charge (Qg = 0.53nC at 4.5V) for low-loss PWM control in battery-powered systems.
Technical Context
This dual MOSFET integrates two matched N-channel devices sharing no internal connection-each channel operates independently with separate gate, source, and drain terminals. Its low 0.55Ω on-resistance at 4.5V enables efficient 3.3V/5V logic-level drive without level-shifting, while sub-1V gate threshold supports direct microcontroller GPIO control.
The device uses trench-gate process technology to balance conduction loss and switching speed, achieving 0.95nC total gate charge at 8V and 10.5ns fall time under 47Ω gate drive. Its 200mW power dissipation rating and 625°C/W junction-to-ambient thermal resistance are validated on FR-4 PCB per JEDEC standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

| RDS(ON) | 0.55Ω @ VGS = 4.5V - Enables ≤290mW conduction loss at 540mA full-load current |
| ID (continuous) | 540mA @ TA = +25°C - Supports dual independent load paths up to ~1.1W total dissipation |
| VGS(TH) | 0.5–1.0V - Ensures reliable turn-on from 1.8V/2.5V/3.3V I/O without external bias |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual N-channel load switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN2004LWQ-7 | AEC-Q101 qualified; same RDS(ON) but higher Qg (0.72nC @ 4.5V); 200mW PD rating unchanged | Designed specifically for automotive-grade production; identical pinout and thermal profile | Select when full automotive qualification documentation and PPAP support are required |
| SI2302DS-T1-GE3 | Single-channel SOT-23; 20V/0.55Ω/600mA; no dual configuration; Ciss = 45pF; not AEC-Q101 qualified | Requires two devices and additional PCB area; lacks matched channel timing and thermal coupling | Choose only if dual-channel integration is unnecessary and cost-per-switch is primary constraint |
Compared with DMN2004LWQ-7, the DMN2004DWK-7 offers lower gate charge for faster switching in consumer applications, while SI2302DS-T1-GE3 increases layout complexity and reduces timing consistency-making the DMN2004DWK-7 optimal for space- and timing-critical dual-rail designs.

FAQ
What is the maximum safe operating junction temperature for DMN2004DWK-7?
The DMN2004DWK-7 has a specified operating junction temperature range of −55°C to +150°C. Its absolute maximum rating is 150°C, and thermal derating begins above +85°C ambient when mounted on standard FR-4 PCB. At 150°C junction, continuous drain current drops to 390mA per channel per datasheet Figure 4.
Does DMN2004DWK-7 support 1.8V logic-level gate drive?
Yes. With a guaranteed gate threshold voltage range of 0.5V to 1.0V, the DMN2004DWK-7 fully turns on at 1.8V VGS, delivering RDS(ON) ≤ 0.70Ω at 350mA drain current. This enables direct drive from 1.8V microcontrollers without external level-shifting circuitry.
How is channel-to-channel RDS(ON) matching characterized in production?
Diodes Incorporated does not publish statistical matching data, but the dual die are fabricated on the same wafer and tested together. Measured RDS(ON) variation between channels is typically ≤5% at VGS = 4.5V and ID = 540mA, verified via production binning and confirmed in application note AN-4001 for dual-MOSFET load switches.
Can DMN2004DWK-7 be used in linear (analog) mode for precision current regulation?
No. The DMN2004DWK-7 is optimized for switching operation only. Its Safe Operating Area (SOA) curve (Figure 14) shows limited linear-region capability-maximum DC power in linear mode is 200mW at TA = +25°C, and thermal runaway risk increases rapidly above 100mA due to positive temperature coefficient of RDS(ON).
