STM4635-VB Product details
Back to previous pageProduct introduction：
Still troubled by low efficiency and high heat generation in negative voltage power conversion? Let VBsemi STM4635-VB solve your worries! This single P-channel MOS tube in SOP8 package confidently handles demanding loads with -40V withstand voltage and -16.1A high current capability. Its on-resistance is as low as 10mΩ @ 10V, significantly reducing heat generation. The Trench process gives it excellent switching characteristics and low loss performance. With a wide drive range, it becomes a reliable 'power cornerstone' in the hands of engineers, whether for battery management or motor control.
