FDS8333C is listed in the FET, MOSFET Arrays range at ChipApex. The manufacturer field lists onsemi. Its product description is MOSFET N/P-CH 30V 4.1A 8SOIC. Review the specifications below when checking this part for your BOM.
The FDS8333C is a dual N and P-Channel PowerTrench MOSFET manufactured by Fairchild Semiconductor. It utilizes an advanced trench process to minimize on-state resistance while maintaining superior switching performance. The device features a drain-source voltage of 30V for both channels. The N-channel (Q1) supports a continuous drain current of 4.1A with an RDS(on) of 80mΩ at VGS=10V, while the P-channel (Q2) supports 3.4A with an RDS(on) of 130mΩ at VGS=-10V. Packaged in an SO-8 surface mount format, it offers low gate charge and high power handling capability suitable for battery-powered applications.
Verify the manufacturer origin as Fairchild Semiconductor or its successor entity onsemi. Confirm the specific ordering suffix matches the required reel size and tape width specifications. Ensure the component marking aligns with the official datasheet documentation to prevent counterfeit substitution during acquisition.
Select this component when space constraints preclude larger packages like SO-8 or TSSOP-8 but higher power dissipation than smaller alternatives is needed. Evaluate thermal resistance requirements based on the specific copper pad area available on the PCB layout. Consider the gate threshold voltage characteristics for compatibility with the intended logic drive levels.
This part belongs to the PowerTrench family of MOSFETs designed for efficiency. It serves as a compact solution for applications requiring both N-channel and P-channel switching capabilities without occupying excessive board real estate. The design targets scenarios where minimizing inline power loss is critical alongside rapid switching speeds.
