TK6A45DA(STA4,Q,M)-VB Product details
Back to previous pageProduct introduction：
You are designing a high-reliability switching power supply and need to handle a 650V bus high voltage, but also control conduction losses and temperature rise. Ordinary MOS tubes either lack sufficient voltage resistance or have high on-resistance. VBsemi TK6A45DA is designed for this purpose—it uses planar technology to achieve 650V withstand voltage, 10A continuous current capability, and an on-resistance of 830mΩ (at 10V drive) in a TO220F package, providing a solid and reliable switching core for high-power, high-voltage applications, allowing industrial-grade power supply design to no longer compromise.
