FDV303N

FDV303N Description

The FDV303N from onsemi is an N-channel MOSFET designed for low-voltage, high-efficiency switching applications. With a drain-to-source voltage (Vdss) of 25V and a continuous drain current (Id) of 680mA, this surface-mount device is optimized for compact, power-sensitive designs. It features a low on-resistance (Rds(on)) of 450mΩ at 4.5V gate drive, ensuring minimal conduction losses. The MOSFET operates with a gate threshold voltage (Vgs(th)) as low as 1.5V, making it compatible with low-voltage logic circuits. Packaged in SOT-23 and supplied in Tape & Reel (TR), it is ideal for automated assembly processes.

FDV303N Features

• Low Gate Charge (Qg): 2.3nC at 4.5V enables fast switching, reducing power losses in high-frequency applications.
• Low Input Capacitance (Ciss): 50pF at 10V minimizes drive requirements, improving efficiency.
• Wide Gate-Source Voltage Range (Vgs): ±8V ensures robust operation under varying conditions.
• High Power Dissipation: 350mW (Ta) allows reliable performance in thermally constrained environments.
• RoHS3 & REACH Compliant: Meets environmental and regulatory standards for global use.
• Moisture Sensitivity Level (MSL) 1: Suitable for extended storage without requiring baking.

FDV303N Applications

The FDV303N excels in portable electronics, power management, and load switching, including:

• Battery-Powered Devices: Efficient power switching in smartphones, wearables, and IoT sensors.
• DC-DC Converters: Low-loss synchronous rectification in step-down/step-up converters.
• Signal Switching: High-speed toggling in analog/digital multiplexers.
• Motor Control: Driver circuits for small brushed DC motors.
  Its compact SOT-23 package and low Rds(on) make it superior to bulkier alternatives in space-constrained designs.
