Product details
Overview
DMN2450UFB4Q-7B from Diodes Incorporated is an AEC-Q101 qualified N-channel enhancement-mode MOSFET in X2-DFN1006-3 package, designed for low-voltage load switching with 20V VDSS, 0.4Ω RDS(ON) @ 4.5VGS, and 1.0A continuous drain current at +25°C - deployed in automotive body control modules, USB power switches, and portable battery management systems.
For engineers reviewing the DMN2450UFB4Q-7B datasheet, DMN2450UFB4Q-7B pinout, DMN2450UFB4Q-7B application, or DMN2450UFB4Q-7B equivalent, key selection criteria include gate threshold voltage (0.5–0.9V), ultra-small 0.6mm² footprint, ESD-protected gate, thermal resistance (129°C/W on 25mm² copper), and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This MOSFET employs a trench-gate process to achieve low RDS(ON) while maintaining fast switching (tD(ON) = 5.3ns, tF = 6.6ns) and low gate charge (Qg = 0.6nC @ 4.5V). Its 0.4mm profile and NiPdAu-plated terminals support fine-pitch PCB assembly and high-reliability solder joints.
The device integrates an ESD-protected gate structure and intrinsic body diode (VSD = 0.7–1.2V @ 150mA), enabling bidirectional current handling in reverse-battery protection and hot-swap circuits without external components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 20V - Supports 12V automotive and 5V/3.3V logic-supplied systems with margin against transients. |
| RDS(ON) | 0.4Ω @ VGS = 4.5V - Enables <100mW conduction loss at 500mA, critical for thermally constrained space-constrained designs. |
| ID (max) | 1.0A @ TA = +25°C - Sustains full-rated current in ambient-cooled applications like USB-C PD load switches. |
| VGS(TH) | 0.5–0.9V - Ensures reliable turn-on with 1.8V/2.5V/3.3V GPIOs, eliminating need for level-shifting drivers. |
| Qg | 0.6nC @ VGS = 4.5V - Reduces gate drive power and enables >1MHz PWM operation in DC-DC post-regulators. |
| RθJA | 129°C/W (with 25mm² copper) - Allows 0.9W power dissipation in compact layouts without forced air or heatsinks. |
| Ciss | 56pF - Minimizes capacitive loading on driving microcontrollers and reduces EMI during edge transitions. |
Pinout & Package
Package: X2-DFN1006-3 (1.0 × 0.6 × 0.4 mm), molded green compound, UL 94V-0 rated, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Source) | Source terminal (S) | Low-side return path; internally connected to exposed thermal pad for enhanced heat transfer to PCB. |
| Pin 2 (Gate) | Control input (G) | ESD-protected gate node; requires no external series resistor for typical 3.3V MCU drive due to low Qg. |
| Pin 3 (Drain) | Power output (D) | High-current output node; connects to load or supply rail; optimized for minimal parasitic inductance in DFN layout. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-small footprint | 0.6mm² area - 13× smaller than SOT-23, enabling dense integration in wearable and ADAS sensor modules. |
| AEC-Q101 qualification | Validated for automotive temperature range (−55°C to +150°C) and PPAP-capable manufacturing per IATF 16949. |
| Low-profile height | 0.4mm max - Compatible with stacked PCB assemblies and conformal coating processes in infotainment head units. |
| ESD-protected gate | HBM ≥2kV - Eliminates need for external gate protection in production lines handling unshielded PCBs. |
| Halogen- and antimony-free | <900ppm Br, <900ppm Cl, <1000ppm Sb - Meets automotive OEM green material specifications (e.g., GMW3172, Ford WSS-M99P9999-A1). |
Applications
| Automotive Body Control Module | USB Type-C Power Delivery Switch |
|---|---|

Use Scenario: Low-side power switch for interior lighting, mirror heaters, and door lock actuators in 12V vehicle architectures. IC Role / Device Role / Timing Role: Load switch controlling 12V supply to resistive loads up to 10W, with fast turn-off (<25ns fall time) to suppress inductive kickback. Use Value: 0.4Ω RDS(ON) limits self-heating to <5°C rise at 1A, avoiding thermal derating in sealed junction boxes. |
Use Scenario: VBUS enable/disable switch in USB-C receptacles supporting 3A/20V PD profiles. IC Role / Device Role / Timing Role: High-side or low-side power path controller with 20V rating and sub-1V gate threshold for direct MCU control. Use Value: 0.4mm profile allows placement under USB-C connector footprint, reducing board layer count in thin mobile accessories. |
| Portable Battery Management System | Industrial IoT Sensor Node Power Gate |
|
Use Scenario: Reverse-battery and overcurrent protection in Li-ion-powered handheld tools and medical monitors. IC Role / Device Role / Timing Role: Bidirectional load switch leveraging intrinsic body diode for reverse-polarity blocking and low-loss forward conduction. Use Value: VGS(TH) ≤0.9V ensures turn-on even at end-of-discharge (2.8V cell), preserving system uptime during brownout conditions. |
Use Scenario: Power gating of wireless transceivers (BLE/Zigbee) and analog front-ends in battery-operated edge nodes. IC Role / Device Role / Timing Role: Low-quiescent-load power switch enabling <1μA shutdown current when paired with high-impedance gate drive. Use Value: 100nA IDSS at 20V ensures <10nW leakage per switch, extending 10-year battery life in LPWAN deployments. |
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 |
|---|---|---|---|
| DMN2058UFB4-7 | 20V VDSS, 0.35Ω RDS(ON) @ 4.5VGS, but only qualified to industrial grade (−40°C to +125°C), not AEC-Q101. | Lacks automotive qualification and PPAP documentation; unsuitable for OEM Tier-1 BOMs requiring change control traceability. | Select when cost sensitivity outweighs automotive compliance requirements and thermal margin exceeds 0.35Ω performance. |
| AO3414 | 20V VDSS, 0.042Ω RDS(ON) @ 4.5VGS, but in larger SOT-23 package (2.9 × 1.3 × 1.0 mm) and non-AEC-Q101. | Higher RθJA (200°C/W) and larger footprint limit use in space-constrained automotive modules. | Prefer where lower conduction loss justifies larger PCB area and non-automotive qualification is acceptable. |
Compared with DMN2058UFB4-7 and AO3414, the DMN2450UFB4Q-7B uniquely balances AEC-Q101 compliance, 0.4mm profile, and 0.4Ω RDS(ON) - making it the only option meeting automotive mechanical, thermal, and qualification constraints simultaneously.

FAQ
Is DMN2450UFB4Q-7B suitable for hot-swap applications?
Yes. Its low RDS(ON) (0.4Ω @ 4.5VGS), fast switching (tF = 6.6ns), and integrated ESD protection make it well-suited for hot-swap circuits in USB-C and PCIe add-in cards. The 20V VDSS provides margin against inrush-induced overshoot, and the 0.4mm profile supports tight placement near connectors.
What is the maximum allowable gate-source voltage for safe operation?
The absolute maximum VGS is ±12V per the datasheet's Maximum Ratings table. Operation beyond this risks permanent gate oxide damage. For robust 3.3V or 5V MCU drive, no external gate resistor is required due to low Qg (0.6nC) and built-in ESD protection.
Does the X2-DFN1006-3 package require special PCB layout considerations?
Yes. The exposed thermal pad must be connected to a minimum 25mm² copper pour using at least four thermal vias (0.3mm diameter) to achieve the 129°C/W RθJA. Pad dimensions follow Diodes' recommended layout: 0.45 × 0.55 mm for solder mask opening and 0.6 × 1.2 mm for copper land.
How does the device perform at elevated junction temperatures?
RDS(ON) increases by ~25% from 25°C to 125°C at VGS = 4.5V (Figure 5), remaining within 0.5Ω. Gate threshold voltage decreases slightly (0.5–0.9V range narrows), ensuring consistent turn-on behavior across −55°C to +150°C operating range per AEC-Q101 stress testing.
