Product details
Overview
DMN2019UTS from Diodes Incorporated is a 20V N-channel enhancement-mode MOSFET in TSSOP-8 package, optimized for low RDS(on) (18.5 mΩ @ VGS = 10 V) and fast switching in load-switch applications. It delivers 5.4 A continuous drain current at 25°C, supports 2 kV ESD protection, and meets AEC-Q101 for automotive-grade reliability.
For engineers reviewing the DMN2019UTS datasheet, DMN2019UTS pinout, DMN2019UTS application, or DMN2019UTS equivalent, key selection criteria include gate threshold voltage (0.35–0.95 V), RDS(on) vs. VGS performance down to 1.8 V, thermal resistance (RθJA = 161 °C/W), and dual-channel internal configuration for compact power routing.
Technical Context
This MOSFET integrates two independent N-channel channels in a single TSSOP-8 die, sharing source terminals (S1/S2) and gate terminals (G1/G2) as shown in the internal schematic. Its low gate charge (Qg = 8.8 nC @ VGS = 4.5 V) and fast switching times (tD(off) = 562 ns) enable high-efficiency DC-DC and load-switch control with minimal drive loss.
The device operates across –55°C to +150°C, with RDS(on) normalized to 1.4× at 125°C (VGS = 4.5 V), and features a body diode with VSD = 0.7–1.0 V @ IS = 1 A. Its 26 °C/W junction-to-case thermal resistance supports localized heat dissipation in space-constrained PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 20 V - Maximum drain-source blocking voltage for 12 V rail switching and USB PD input stage protection |
| RDS(on) @ VGS = 4.5 V | 21 mΩ - Enables ≥95% efficiency in 3.3 V/5 V load switches at 5 A with <0.5 W conduction loss |
| ID continuous @ 25°C | 5.4 A - Supports dual-rail hot-swap or redundant power path designs without external heatsinking |
| Qg | 8.8 nC - Reduces gate driver power demand and enables direct MCU GPIO driving at ≤10 MHz PWM |
| RθJA | 161 °C/W - Requires minimum 2 oz copper pad layout per AP02001 for safe 0.78 W operation at ambient ≤70°C |
| ESD rating | 2 kV HBM - Eliminates need for external TVS in consumer-grade portable power management interfaces |
| AEC-Q101 qualified | Yes - Validated for automotive body electronics, infotainment power sequencing, and ADAS subsystems |
Pinout & Package
Package: TSSOP-8, surface-mount, green molding compound (UL 94V-0), 0.039 g mass, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | Source 1 (S1) | Common source node for first N-channel channel; tied internally to Pin 4 (S2) for dual-channel parallel use |
| 4 | Source 2 (S2) | Shared source terminal with S1; enables synchronous dual-path conduction or independent sourcing when isolated |
| 5, 6 | Drain 1 (D1) | Primary drain connection for Channel 1; electrically isolated from D2 (Pins 7 & 8) for split-load routing |
| 7, 8 | Drain 2 (D2) | Independent drain for Channel 2; allows separate load control or current sensing per channel |
| G1 (Pin 1 top mark) | Gate 1 | Control input for Channel 1; driven independently or paralleled with G2 for combined switching |
| G2 (Pin 2 top mark) | Gate 2 | Control input for Channel 2; decoupled gate capacitance (Ciss = 143 pF total) minimizes crosstalk |
Key Features
| Feature | Design Value |
|---|---|
| Dual N-channel topology | Two independent 20 V/5.4 A switches in one TSSOP-8 footprint-reduces board area by 40% vs. discrete dual-MOSFET solutions |
| Low RDS(on) at 2.5 V drive | 24 mΩ @ VGS = 2.5 V enables direct interfacing with 2.5 V logic and low-voltage microcontrollers |
| Fast turn-off delay | tD(off) = 562 ns ensures precise timing control in synchronous buck converters and active OR-ing circuits |
| Thermally robust construction | RθJC = 26 °C/W allows direct thermal coupling to inner-layer copper planes for sustained 0.78 W dissipation |
| Automotive-qualified reliability | AEC-Q101 qualification confirms stable parametric performance after 1000-hour HTOL and temperature cycling stress |
Applications

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 |
|---|---|---|---|
| DMN2022UTS-13 | RDS(on) = 22 mΩ @ 4.5 V; higher Qg (10.2 nC); same TSSOP-8 pinout | Lower efficiency at high current; slower switching due to increased gate charge | Select when cost sensitivity outweighs 5% conduction loss penalty and 15% longer tD(off) |
| SI6926ADQ-T1-GE3 | Single-channel 30 V/6.5 A; RDS(on) = 20 mΩ @ 4.5 V; no dual-source integration | Requires two devices and extra PCB area for dual-path function; lacks shared-source optimization | Choose only if legacy design uses SO-8 footprints and dual-channel integration is not required |
Compared with DMN2019UTS, DMN2022UTS offers lower cost but sacrifices 10% switching speed and 2.5% conduction efficiency; SI6926ADQ requires double the layout area and discrete gate drive coordination, increasing BOM count and signal integrity risk.

FAQ
Is DMN2019UTS pin-compatible with standard TSSOP-8 MOSFETs?
No-DMN2019UTS has a proprietary dual-channel pinout: Pins 1–4 are S1/S2/G1/G2, while Pins 5–8 are D1/D1/D2/D2. Standard single-channel TSSOP-8 MOSFETs assign Gate to Pin 1 and Drain to Pin 8, making direct replacement impossible without PCB redesign.
Can DMN2019UTS operate reliably at 125°C junction temperature?
Yes-the device is rated for TJ = –55°C to +150°C and maintains RDS(on) within 1.4× nominal at 125°C (VGS = 4.5 V). Derating to 3.7 A continuous drain current at 70°C ambient ensures safe operation under full thermal load.
What is the significance of the dual-source (S1/S2) connection in the internal schematic?
The internal tie between S1 (Pins 1–3) and S2 (Pin 4) creates a common-source node for both channels, enabling synchronous switching with one gate drive or independent sourcing when external isolation is applied via PCB routing-critical for current-sharing and fault containment.
Does DMN2019UTS require external gate resistors for typical 3.3 V MCU drive?
No-its low input capacitance (Ciss = 143 pF) and 202 Ω gate resistance allow direct connection to 3.3 V GPIOs driving ≤10 mA peak. For >1 MHz PWM, a 10 Ω series resistor is recommended to damp ringing without compromising rise time (tr = 78 ns).
