π-MOS IV MOSFETs Toshiba π-MOS IV MOSFETs are low-voltage, single N-channel MOSFETs ideal for switching regulator applications. These devices feature low drain-source ON-resistance, high forward transfer admittance, and low leakage loss. These Toshiba devices are offered in 3-pin, through-hole TO-220SIS (JEITA SC-67) and TO-3P(N) (JEITA SC-65) packages.
