FDS86242 NChannel MOSFET 150V, 4.1A, SO8, 10pcs per lot Overview A compact NChannel MOSFET designed for mediumvoltage switching and power management in surface mount applications. The device delivers 150V blocking capability, a continuous current rating of 4.1A at ambient, and defined power dissipation limits for reliable thermal planning. Key benefits voltage switching: 150V rating lets you handle highervoltage rails and loads without needing larger discrete components. Practical current capacity: 4.1A continuous current at ambient conditions fits many power switching and load control tasks. Clear thermal limits: 2.5W power dissipation at ambient temperature and 5W at case temperature allow straightforward thermal design and heatsinking choices. Spacesaving package: Surface mount 8SO package reduces PCB footprint and is compatible with standard SO8 layouts for automated assembly. Consistent, repeatable parts: Supplied as 10 pieces per lot for batch assemblies or spare inventory. Important specifications Model: FDS86242 Type: NChannel MOSFET Maximum drainsource voltage: 150V Continuous current: 4.1A at Ta (ambient) Power dissipation: 2.5W at Ta, 5W at Tc (case) Package: Surface mount 8SO (SO8) Pack quantity: 10pcs per lot Typical applications and use scenarios DCDC converters and power rails: Use as a switching element in voltage stepdown converters or synchronous buck stages where 150V blocking is required. Motor control and driver circuits: Suitable for switching and lowside or side control of small DC motors and actuators in industrial or automotive electronics. LED drivers and lighting control: Implement as a switching transistor in voltage LED driver stages or dimming circuits that require compact surface mount components. Design notes Verify thermal management based on the specified 2.5W at ambient and 5W at case ratings. Use appropriate PCB copper, thermal vias, or heatsinking for sustained power operation. Compatible with standard SO8 footprints and common MOSFET gate driver circuits. Check gate drive voltage and switching speed requirements in your design to ensure performance.
