Description

The DMG2302UKQ-7 is a N-channel enhancement-mode MOSFET from Diodes Incorporated, designed for low-voltage, high-efficiency power switching applications. Key features include:
- 30V drain-source voltage (V_DS)
- 5.8mΩ ultra-low on-resistance (R_DS(on)) at 10V gate drive
- High current capability (60A pulsed, 30A continuous)
- Compact PowerDI^®5 package for space-constrained designs
- Optimized for synchronous rectification, DC-DC converters, and motor control
It operates with a logic-level gate drive (2.5V threshold), making it suitable for battery-powered and portable devices. The low gate charge (Q_G) and fast switching enhance efficiency in high-frequency applications.
Ideal for:
- Power management (e.g., load switches, buck/boost converters)
- USB power delivery
- Industrial and automotive systems
