TK9P65W,RQ-VB Product details
Back to previous pageProduct introduction：
TK9P65W is a Single N-MOS optimized for high-voltage power switching applications, using SJ_Multi-EPI super-junction multi-epitaxial technology to achieve a balance between low on-resistance and low switching loss at a 650V withstand voltage level. The TO252 package combines heat dissipation capability with mounting convenience, and the combination of 8A continuous current capacity and 560mΩ on-resistance makes it a reliable choice for high-voltage applications such as switching power supplies, industrial control, and new energy auxiliary power supplies, especially suitable for scenarios with strict requirements for voltage margin and system stability.
