Product Summary

The W20NK50Z is an N-channel 500V-0.23Ω-20A TO-220/TO-247 zener-protected supermesh power MOSFET. The W20NK50Z is obtained through an extreme optimization of ST well established strip-based PowerMesh layout. Applications of the W20NK50Z include: high current, high speed switching, ideal for off-line power supplies, adaptors and PFC.
