SQM120N04-1M7L_JE3-VB Product details
Back to previous pageProduct introduction：
You are designing a high-power DC-DC converter or motor drive module, facing continuous surge currents of tens of amperes and strict heat dissipation constraints. Ordinary MOSFETs either have high conduction losses or take up too much space, compromising power density. VBsemi SQM120N04-1M7L_JE3-VB is designed for this—it integrates 40V withstand voltage, 280A ultra-high current capacity, and an on-resistance as low as 1.4mΩ in a TO263 high-current package, freeing high-power designs from heating and space concerns.
