FDG6303N

FET, MOSFET Arrays Overview

The FDG6303N is a dual N-channel digital FET manufactured by onsemi. It integrates two N-channel MOSFETs with built-in gate drive circuitry, including pull-down resistors and Zener diodes for gate protection. The device operates with a drain-source voltage (Vds) of 25 V and supports a continuous drain current (Id) of 680 mA. Key electrical parameters include a maximum on-resistance (Rds(on)) of 450 mΩ at Vgs = 4.5 V, a gate charge (Qg) of 2.3 nC, and a threshold voltage (Vgs(th)) of 650 mV. It features rise and fall times of 8.5 ns, a power dissipation (Pd) of 900 mW, and operates within a temperature range of -55°C to +150°C.

FET, MOSFET Arrays Procurement Notes

Verify the manufacturer marking and date code against official onsemi documentation to ensure authenticity. Confirm that the component matches the SSOT-6 package specifications and RoHS compliance status required for your assembly process. Cross-reference the part number with authorized distributors to avoid counterfeit sources.

FET, MOSFET Arrays Selection Notes

Select this component when a dual N-channel switch with integrated gate protection is needed in a small footprint. Ensure the application voltage does not exceed 25 V and the current demand remains below 680 mA. Consider the thermal constraints given the 900 mW power dissipation limit in the SSOT-6 package.

FET, MOSFET Arrays Part Context

The FDG6303N belongs to onsemi's Digital FET family, which combines MOSFETs with control logic. This series is designed to replace discrete MOSFETs and gate drive components, reducing board space and design complexity. It is commonly used in applications where simple on/off control is sufficient without complex PWM requirements.

FET, MOSFET Arrays Replacement Considerations
