4N80 MOSFET in a TO-252 (DPAK) package is a surface-mount, high-voltage N-channel power transistor designed to handle up to 800V and 4A for efficient power switching
Pin Configuration (TO-252 / DPAK)
- Pin 1 (Gate): Controls the turning on and off of the MOSFET.
- Pin 2 (Drain): The main high-voltage terminal connected to the load (electrically tied to the large central mounting tab).
- Pin 3 (Source): The return path terminal for the drain current.
Common Applications
- Switch-mode power supplies (SMPS)
- High-voltage isolated DC-DC converters
- Small offline power adapters and LED driver
