CPH3303-TL-E-VB Product details
Back to previous pageProduct introduction：
Still troubled by power consumption and package size in negative voltage power management or load switching? Let VBsemi CPH3303-TL-E-VB help! This SOT23-3 packaged P-MOSFET, though compact, can handle a continuous current of -4A, with an on-resistance as low as 60mΩ (at 10V), effectively reducing voltage drop and heat generation on high-current paths. The Trench process delivers fast switching and low losses, and the -20V withstand voltage combined with ±12V gate drive easily adapts to common low-voltage portable, battery-powered, and load switching scenarios, making it a reliable partner in power design.
