TK8A50DA(STA4,Q,M)-VB Product details
Back to previous pageProduct introduction：
Are you designing a high-reliability switching power supply, but facing 650V surge impacts on the high-voltage side while needing to maintain a 10A current output capability? Ordinary MOSFETs either lack sufficient voltage withstand capability or have high conduction losses. The VBsemi TK8A50DA is designed for this – it integrates 650V drain-source voltage, 10A current capability, and 830mΩ on-resistance into a reinforced insulated TO220F package, making high-voltage power supply design more composed and safe.
