BUK9508-55A,127-VB Product details

Product introduction:

You are designing a high-power DC-DC converter or motor drive module. Facing a 60V bus voltage and hundreds of amperes of current demand, ordinary MOS tubes either have excessive conduction losses or inadequate thermal performance. VBsemi BUK9508-55A,127-VB is designed for this—it uses a TO220 package to integrate 60V withstand voltage, 120A current capacity, and an on-resistance of only 5mΩ, freeing high-current power designs from heating and voltage drop concerns.
