Description
Marked "16N65MF" on the package with a "PY" logo, this is a 16N65MF-family N-channel power MOSFET, a common generic part number produced by multiple Asian semiconductor manufacturers. It's housed in the isolated TO-220MF (Modified F-pack) package, a two-pin-plus-tab variant commonly used to allow direct heatsink mounting without a separate insulating pad.

The 16N65MF is built for offline switch-mode power supply applications, offering the standard feature set common to this class of 650V super-junction/planar MOSFET: low gate charge for faster switching, low input capacitance (Ciss) to reduce driving losses, 100% avalanche testing for ruggedness, and improved dv/dt capability for robustness against fast voltage transients.
