TK20P04M1,RQ(S-VB Product details
Back to previous pageProduct introduction：
Imagine: You are designing a high-power DC-DC converter or motor drive module that needs to handle surge currents up to 50A, while also controlling heat dissipation and board space. Ordinary TO-252 package MOS transistors often struggle to balance conduction loss and heat dissipation. VBsemi TK20P04M1,RQ(S-VB is designed for this—it uses Trench technology to perfectly combine 40V withstand voltage, 55A continuous drain current, and an ultra-low on-resistance of 12mΩ in a TO252 package, making high-current power supply design more relaxed and efficient.
