Description:25 V, 0.50 A continuous, 1.5 A Peak. ; Compact industry standard SC70-6 surface mount package. ; RDS(ON) = 0.45 Ω @ VGS= 4.5 V, ; Gate-Source Zener for ESD ruggedness (>6kV Human Body Model). ; RDS(ON) = 0.60 Ω @ VGS= 2.7 V. ; Very low level gate drive requirements allowing direct operation in 3 V circuits (VGS(th) <1.5 V).
The maximum junction temperature of the FDG6303N is 150°C. However, it's recommended to keep the junction temperature below 125°C for reliable operation.
To ensure proper biasing, connect the gate pin to a voltage source that is at least 2V higher than the source pin, and the drain pin should be connected to a voltage source that is at least 1V higher than the gate pin. Additionally, ensure the gate-source voltage (Vgs) is within the recommended range of 2V to 10V.
To minimize parasitic inductance and capacitance, use a compact PCB layout with short leads and minimize the distance between the drain, gate, and source pins. Use a ground plane under the device to reduce inductance and ensure good thermal conduction. Avoid using vias under the device and keep the PCB traces as short and wide as possible.
To protect the FDG6303N from ESD, handle the device by the body or use an anti-static wrist strap or mat. Ensure the PCB is designed with ESD protection in mind, such as using ESD protection diodes or resistors. Store the device in an anti-static bag or container when not in use.
To ensure proper thermal management, use a heat sink with a thermal resistance of less than 10°C/W. Apply a thin layer of thermal interface material (TIM) between the device and heat sink. Ensure good airflow around the device and heat sink to prevent thermal hotspots.
