Diodes Incorporated DMN2004VK-7B

Overview

DMN2004VK-7B from Diodes Incorporated is a dual N-channel enhancement-mode MOSFET in SOT563 package, rated for 20 V V_DSS, 540 mA continuous drain current at 25°C, and 0.4 Ω typical R_DS(ON) at V_GS = 4.5 V. It features ESD-protected gates, ultra-low input capacitance (150 pF), and fast switching (t_R = 13.3 ns), targeting compact load-switching and power management in space-constrained portable electronics.

For engineers reviewing the DMN2004VK-7B datasheet, DMN2004VK-7B pinout, DMN2004VK-7B application, or DMN2004VK-7B equivalent, key selection criteria include its dual-channel layout in 1.6 mm × 1.6 mm SOT563, low 0.5 V gate threshold enabling 1.8 V logic drive, and thermal resistance of 500 °C/W - critical for battery-powered wearables and IoT sensor nodes requiring high efficiency at low voltage.

Technical Context

This dual MOSFET integrates two independent N-channel devices sharing no internal connection - each channel operates with identical electrical characteristics and separate gate, source, and drain terminals. Its low 0.5 V minimum V_GS(TH) ensures reliable turn-on with 1.8 V and 2.5 V microcontroller I/O, while 250 mW total power dissipation is defined under JEDEC-standard FR-4 PCB conditions with 2 oz copper.

The device uses a "Green" halogen- and antimony-free molding compound (UL 94V-0), with matte tin-annealed terminals solderable per MIL-STD-202 Method 208. Moisture sensitivity level is J-STD-020 Level 1, eliminating bake requirements prior to reflow.

Key Specifications

Pinout & Package

SOT563 is a 6-pin ultra-small surface-mount package (1.60 mm × 1.60 mm × 0.60 mm) with dual-drain-exposed configuration. Pin 1 and Pin 4 are Gate terminals; Pins 2 & 5 are Source; Pins 3 & 6 are Drain - each channel occupies pins 1–2–3 and 4–5–6 respectively.

FAQ

What is the maximum continuous drain current for each channel at 85°C ambient?

Each channel supports 390 mA continuous drain current at TA = +85°C, as specified in the Absolute Maximum Ratings table. This derating reflects thermal limits under JEDEC-standard FR-4 PCB conditions (2 oz copper, minimum pad layout). Actual current capability depends on PCB copper area, airflow, and adjacent heat sources.

Does DMN2004VK-7B support 1.8 V logic-level drive without external level shifting?

Yes. With a guaranteed V_GS(TH) range of 0.5–1.0 V and R_DS(ON) = 0.55 Ω max at V_GS = 1.8 V and I_D = 350 mA, the device fully enhances using standard 1.8 V GPIO outputs - confirmed by datasheet Figure 7 and Electrical Characteristics table.

Is the SOT563 package lead-free and RoHS-compliant?

Yes. DMN2004VK-7B is fully lead-free and compliant with EU RoHS directives 2002/95/EC, 2011/65/EU, and 2015/863/EU. The package uses matte tin-annealed terminals over copper lead frame and a halogen- and antimony-free "Green" molding compound meeting UL 94V-0 flammability rating.

Can both channels be paralleled to increase current handling?

No. The datasheet specifies independent operation only - no internal matching or thermal coupling guarantee exists between channels. Paralleling would cause current imbalance due to V_GS(TH) and R_DS(ON) tolerances (±20% typical), risking thermal runaway. Use a single-channel part rated for higher current instead.
