SQ3985EV-T1_GE3-VB Product details
Back to previous pageProduct introduction：
Still troubled by power consumption and space issues in negative voltage power management? Let VBsemi SQ3985EV-T1_GE3-VB help! This SOT23-6 packaged dual P-channel MOS transistor integrates two independent P-MOS transistors, saving board-level area while easily handling load switches, battery protection, and other low-voltage scenarios with its -4A current capability and low on-resistance as low as 75mΩ. Trench technology ensures fast switching and low loss. -20V withstand voltage combined with ±12V drive perfectly fits common portable and industrial control equipment. It is a 'dual-channel tool' for low-voltage negative power supply design.
