Description:

This is an electronic component called a MOSFET — think of it as a high-power electronic switch. It's used inside circuits to turn power on/off very quickly and control high voltage/current, without needing a mechanical switch. It's commonly found inside power supplies, inverters, welding machines, induction cookers, and other high-power electronic equipment.

Key Details:

• Brand: Toshiba (genuine)
• Part Number: K065N65Z
• Type: N-Channel Power MOSFET
• Package: TO-247 (3-pin, with metal tab for heatsink mounting)
• Voltage Rating: 650V (the "65" in the name typically indicates this)
• Use: Switching power supplies, inverters, motor drives, induction heating, welding equipment

Why it's useful:

This component handles high voltage and current efficiently while generating less heat, making it ideal for power electronics that need to run reliably for a long time — like SMPS (switch mode power supplies), UPS systems, inverter ACs, and industrial power circuits.

Physical Features:

✅ 3 metal legs (Gate, Drain, Source) for circuit board or wire mounting
✅ Metal tab with mounting hole for attaching a heatsink (helps dissipate heat)
✅ Genuine Toshiba branding and batch code printed on the body

Package Includes: 

• 1x Toshiba K065N65Z Power MOSFET
