About this product
Description
Marked "K40A10N1" on the package with Toshiba's logo, this is Toshiba's TK40A10N1 , part of their U-MOS IV power transistor series. It is an N-channel enhancement mode MOSFET built in a fully isolated TO-220SIS (TO-220F equivalent) plastic package, designed specifically for low-voltage, high-current switching applications.
It features an extremely low drain-source on-resistance ( $R_{DS(ON)}$ ), low gate charge ( $Q_g$ ), and excellent switching speed, making it exceptionally well-suited for efficient power conversion and motor drive circuits.
