• HIGH VOLTAGE - FOR OFF-LINE SMPS
• ULTRA FAST SWITCHING FOR OPERATION
AT<100KHz
• EASY DRIVE - FOR REDUCED COST AND
SIZE
INDUSTRIAL APPLICATIONS:
• SWITCH MODE POWER SUPPLIES
• MOTOR CONTROLS
N - channel enhancement mode POWER MOS field
effect transistor. Easy drive and very fast switch-
ing times make this POWER MOS transistor ideal
for high speed switching applications.
Typical applications include switching power sup-
plies, uninterruptable power supplies and motor
speed control.
