BUK661R6-30C,118-VB Product details
Back to previous pageProduct introduction：
You are designing a high power density, high-current power module where even the copper traces on the PCB need to be thickened, yet you still have to handle continuous currents of tens of amperes. Ordinary MOSFETs either have high conduction losses or complex thermal designs. The VBsemi BUK661R6-30C,118-VB is designed for this purpose—it packs 30V voltage tolerance, a massive 260A current capacity, and an on-resistance of only 1.4mΩ into the industry-standard TO263 package, allowing high-power conversion and battery protection designs without compromise.
