AG508EGD3HRBTL-VB Product details
Back to previous pageProduct introduction：
Imagine this: You are designing a high-power battery management system or motor drive module that needs to handle a continuous current of up to 40A, while also facing the stringent requirements of negative voltage topologies. Ordinary P-channel MOS transistors either have excessive on-resistance, leading to severe heat generation, or insufficient voltage withstand capability, causing worry. VBsemi AG508EGD3HRBTL-VB is designed for precisely this—it combines -40V withstand voltage, -40A current carrying capacity, and an on-resistance as low as 17mΩ within the robust TO252 package, making high-power P-channel switch design effortless.
