TK125A60Z1,S4X-VB Product details
Back to previous pageProduct introduction：
TK125A60Z1,S4X-VB is a Single N-MOS deeply optimized for high-voltage power switching scenarios. The SJ_Multi-EPI (super junction multi-epitaxial) process balances low conduction losses with high switching speed, and the TO220F fully encapsulated package provides good heat dissipation performance and electrical insulation reliability. The combination of 600V voltage resistance, 20A current carrying capacity, and 150mΩ on-resistance makes it a cost-effective power switch option for switching power supplies, industrial control, and new energy applications, especially suitable for systems with strict requirements for high-voltage margins and thermal reliability.
