RD3G08DBLHRBTL-VB Product details
Back to previous pageProduct introduction：
Imagine: You are designing a high-power DC-DC converter or power tool power supply that needs to withstand current surges of hundreds of amperes while controlling conduction losses and temperature rise. Ordinary MOS tubes either have insufficient voltage tolerance or high on-resistance, leading to increasingly larger heatsinks. The VBsemi RD3G08DBLHRBTL-VB is born to solve this problem—it integrates 40V withstand voltage, 120A high current capability, and an ultra-low on-resistance of only 1.6mΩ into the TO252 package, allowing high-power designs to no longer compromise on heat generation and space.
