Product details
Overview
DMN2710UT-7 from Diodes Incorporated is an N-channel enhancement-mode MOSFET in SOT523 package, rated for 20V VDSS, 0.45Ω RDS(ON) @ 4.5V VGS, and 0.87A continuous drain current at 25°C - optimized for ultra-compact load switching in space-constrained DC-DC converters.
For engineers reviewing the DMN2710UT-7 datasheet, DMN2710UT-7 pinout, DMN2710UT-7 application, or DMN2710UT-7 equivalent, key selection criteria include low-voltage gate drive compatibility (1.8V–4.5V), sub-1Ω on-resistance across temperature, ESD-protected gate, and thermal performance under FR-4 PCB mounting conditions.
Technical Context
This MOSFET employs a planar trench-gate process to achieve low RDS(ON) while maintaining fast switching (tD(ON) = 4.9ns, tF = 174ns) and low gate charge (Qg = 0.6nC). Its 0.14Ω typical RDS(ON) at 4.5V enables high-efficiency operation in battery-powered systems.
The device features integrated ESD protection (HBM >2kV), ultra-low input capacitance (Ciss = 42pF), and guaranteed gate threshold voltage range of 0.5–1.0V - supporting reliable turn-on with weak-drive controllers and enabling use in low-power always-on circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 20V - supports 12V rail switching and 5V/3.3V logic-level power domains without derating. |
| RDS(ON) @ 4.5V | 0.45Ω max - delivers ≤0.35W conduction loss at 0.87A, critical for thermally limited SOT523 footprint. |
| ID (25°C) | 0.87A - sufficient for USB port power switches and sensor bias rails in portable electronics. |
| Qg | 0.6nC - enables fast, low-energy gate driving with microcontroller GPIOs or low-current drivers. |
| Ciss | 42pF - minimizes Miller effect and improves noise immunity in high-frequency switching nodes. |
| VGS(TH) | 0.5–1.0V - ensures robust turn-on with 1.8V I/O systems and reduces risk of partial conduction during brown-out. |
| PD (FR-4) | 0.32W - defines maximum steady-state power dissipation on standard PCB layout per JEDEC standards. |
Pinout & Package
SOT523 is a 3-pin ultra-small surface-mount package (1.60 × 1.60 × 0.75 mm) with gull-wing leads, designed for high-density PCB layouts and automated placement. Thermal resistance is 395°C/W (steady-state, minimum pad) and 241°C/W (with 1-inch² copper thermal bias).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| G (Gate) | Control terminal | Accepts 0–4.5V logic signals; ESD-protected; requires <0.6nC charge for full turn-on. |
| S (Source) | Reference node | Common return path for load current; tied to system ground or low-side reference in high-side configurations. |
| D (Drain) | Power output | Switches up to 20V supply; conducts bidirectionally when body diode forward-biased (VSD = 0.7–1.2V). |
Key Features
| Feature | Design Value |
|---|---|
| Low RDS(ON) at 2.5V VGS | 0.6Ω max - enables direct drive from 2.5V microcontrollers without level-shifting circuitry. |
| Ultra-small SOT523 footprint | 1.6mm × 1.6mm area - saves >60% board space vs. SOT23, critical for wearables and hearing aids. |
| ESD-protected gate | HBM >2kV - eliminates need for external gate protection in production assembly and field operation. |
| Low leakage | IDSS ≤100nA @ 20V - preserves battery life in always-on standby modes (e.g., RTC backup, sensor wake-up). |
| Green, RoHS-compliant | Halogen- and antimony-free (<900ppm Br/Cl, <1000ppm Sb) - meets automotive and medical regulatory requirements. |
Applications
| Battery-Powered Load Switch | USB Port Power Control |
|---|---|
|
Use Scenario: Enabling/disabling power to Bluetooth LE modules or sensors in coin-cell–powered IoT nodes. IC Role / Device Role / Timing Role: Low-side load switch controlled by MCU GPIO; operates in static on/off mode with <1μs response. Use Value: Achieves <100nA total system quiescent current in off-state due to ultra-low IDSS and gate leakage. |
Use Scenario: Controlling VBUS power delivery to downstream USB peripherals in portable hubs or docking stations. IC Role / Device Role / Timing Role: High-speed enable switch with fast turn-off (tF = 174ns) to prevent backfeed during hot-plug events. Use Value: Prevents bus contention and ensures USB-IF compliance via controlled rise/fall times and low Coss. |
| DC-DC Converter Synchronous Rectifier | Always-On Sensor Bias Rail |
|
Use Scenario: Replacing Schottky diodes in 3.3V buck converter outputs for wearables and medical patches. IC Role / Device Role / Timing Role: Synchronous rectifier driven by controller's complementary PWM signal; handles reverse recovery (tRR = 88ns). Use Value: Reduces conduction loss by 40% vs. 0.3V Schottky, improving efficiency from 88% to 92% at 200mA load. |
Use Scenario: Providing stable 1.8V bias to MEMS accelerometers or temperature sensors in industrial monitoring nodes. IC Role / Device Role / Timing Role: Low-dropout pass element in LDO-like configuration; gate driven by precision voltage reference. Use Value: Maintains <±0.5% regulation over -40°C to +85°C due to flat RDS(ON) vs. temperature curve (Fig. 6). |
Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel load switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN2004LK-7 | Higher RDS(ON) (0.8Ω @ 4.5V), larger SOT23 package, higher Qg (1.2nC) | Less suitable for space-constrained designs; better thermal margin for 1.2A loads | Select when board area allows SOT23 and higher current capability is needed over compactness. |
| AO3400A | Lower VDSS (30V), higher RDS(ON) (0.042Ω @ 10V but 0.8Ω @ 2.5V), no ESD rating specified | Requires 10V gate drive for optimal RDS(ON); unsuitable for 1.8V logic interfaces | Choose only if 30V rating is mandatory and gate drive ≥4.5V is guaranteed; avoid for low-voltage systems. |
Compared with DMN2710UT-7, DMN2004LK-7 trades size for thermal headroom, while AO3400A sacrifices low-voltage drive capability for higher breakdown voltage - making DMN2710UT-7 uniquely suited for miniaturized, battery-critical 20V load switching.

FAQ
What is the maximum safe operating junction temperature for DMN2710UT-7?
The absolute maximum junction temperature is +150°C, and the device is characterized across -55°C to +150°C. At 150°C, RDS(ON) increases by ~1.6× versus 25°C (per Fig. 6), so thermal design must ensure TJ stays below this limit under worst-case ambient and power dissipation.
Can DMN2710UT-7 be used in a high-side switch configuration?
Yes, but requires gate drive ≥VIN + VGS(TH). Since VGS(TH) max is 1.0V and VDSS is 20V, it supports high-side use up to 19V input with appropriate level-shifted gate control - however, its SOT523 thermal limits restrict sustained high-side current to ≤0.5A without enhanced cooling.
Is the DMN2710UT-7 qualified for automotive applications?
No - the datasheet explicitly states that automotive qualification (AEC-Q101) requires special change control and PPAP capability, and DMN2710UT-7 is not listed as AEC-qualified. It is intended for commercial/industrial applications only.
What is the recommended PCB pad layout for optimal thermal performance?
Per Diodes' SOT523 layout guide, use a 1.29mm × 0.40mm copper pad for each terminal, with 0.70mm X1 spacing and 1.80mm Y1 overall length. For improved thermal dissipation, connect the source pad to ≥1-inch² internal copper plane using multiple vias - achieving RθJA = 241°C/W instead of 395°C/W.
