SIJ420DP-T1-GE3-VB Product details
Back to previous pageProduct introduction：
You are designing a high power density DC-DC converter with extremely limited board space, yet it needs to continuously carry tens of amperes of load current. Traditional MOSFETs either have packages that are too large or suffer from troublesome conduction losses. VBsemi SIJ420DP-T1-GE3-VB is designed to solve this exact problem—based on Trench technology, it integrates 30V withstand voltage, 90A ultra-high current capability, and an on-resistance as low as 2.8mΩ into an LFPAK56 (PowerPAK SO-8 compatible) package, providing an extremely efficient power switching solution for server power supplies, power tools, and automotive electronics.
