TOPSwitch-IIoffline PWM switch700 V MOSFETTO-220/3legacy product

TOP225YN is a legacy TOPSwitch-II offline PWM switch for isolated or non-isolated switched-mode power supplies, integrating a 700 V MOSFET and control/protection functions in a TO-220/3 package.

Best for

  • Maintenance of existing TOPSwitch-II offline power supplies
  • Flyback or forward converter designs already qualified with TOP225YN

Avoid if

  • New designs requiring an actively recommended component
  • Designs without verified drain-clamp and transformer-saturation margins

Check before use

  • 700 V drain rating and transient clamp margin
  • 2.00 A typical current-limit suitability
  • TO-220/3 source-connected tab and PCB thermal layout
  • Current procurement and compliance status
