Power MOSFET, P Channel, 20V, 4.2A, 0.052 ohm, SOT-23, Surface Mount
Diodes Inc. P-Channel MOSFET, 20V, 4.2A, low 0.052ohm Rds(on). Ideal for power management, DC-DC converters & motor control. SOT-23 package.
The DMG2305UX-7 is a P-channel enhancement mode MOSFET engineered for high-efficiency power management.
It is specifically designed to minimise on-state resistance (RDS(on)) while maintaining superior switching performance. This combination makes it an excellent choice for applications where both power efficiency and fast operation are critical.
Key Features & Benefits
- Low On-Resistance: Features a static drain-source on-resistance of just 40mohm (typical), reducing power loss and heat generation during operation.
- Fast Switching Speed: Enables efficient performance in high-frequency circuits.
- Low Input Capacitance: Contributes to the fast switching characteristics and reduces driver power requirements.
- Robust Electrical Ratings: Capable of handling a drain-source voltage of -20V and a continuous drain current of -4.2A under specified conditions.
- Compact SOT-23 Package: The surface-mount design allows for high-density PCB layouts, saving valuable board space.
Typical Applications
This MOSFET is ideally suited for a variety of modern electronic designs, including:
- LED backlighting drivers and controls
- General power management functions
- DC-DC converters for voltage regulation
- Motor control circuits
With its wide operating temperature range of -55°C to +150°C, it is reliable for use in demanding environments. Its electrical characteristics, including a pulsed drain current of -15A and a maximum gate threshold voltage of -0.9V, provide designers with a versatile and high-performance component for their power electronics projects.
