2SK3404-Z-E1-AZ-VB Product details
Back to previous pageProduct introduction：
You are designing a high-power DC-DC converter or motor drive module, where the PCB needs to handle currents up to 50A while controlling conduction loss and temperature rise. Ordinary MOSFETs either have high on-resistance or insufficient heat dissipation. The VBsemi 2SK3404-Z-E1-AZ-VB is designed for this purpose—it combines a 30V withstand voltage, 50A current capability, and an on-resistance of only 12mΩ in a TO263 heat-dissipating package, making high-current power supply designs both efficient and reliable.
