SSM3J378R,LF-VB Product details
Back to previous pageProduct introduction：
Still compromising on efficiency and heat in negative voltage power management? Let VBsemi SSM3J378R, LF-VB solve your worries! This SOT23-3 packaged P-MOSFET, despite its compact size, can handle a continuous current of -5A, with an ultra-low on-resistance of 34mΩ (at 4.5V), delivering excellent loss control. The Trench process provides fast switching and low gate charge characteristics, and the -20V withstand voltage covers common battery-powered and load switching scenarios, making it a streamlined power design tool for negative voltage domains.
