BUK7619-100B,118-VB Product details
Back to previous pageProduct introduction：
**Product Introduction** You are designing a high-power DC-DC converter or motor drive module, facing a 100V bus voltage and 70A-level current demands. Ordinary MOSFETs either have insufficient voltage tolerance or alarmingly high conduction losses. The VBsemi BUK7619-100B,118-VB is designed for this—it perfectly integrates 100V voltage tolerance, 70A current-carrying capability, and an on-resistance of only 20mΩ into a TO263 package, making industrial-grade power supply design both efficient and reliable.
