SSM3J351R-VB Product details
Back to previous pageProduct introduction：
Struggling with high power consumption and limited layout space in negative voltage power management? Let the VBsemi SSM3J351R-VB solve your problems! This P-MOSFET in a SOT23-3 package, despite its small size, can handle a continuous current of -4.5A with an ultra-low on-resistance of 70mΩ, resulting in lower heat generation compared to similar devices. Leveraging Trench technology, it offers fast switching and low losses. With a -60V voltage rating, it confidently handles industrial control, communication power supplies, and various demanding scenarios, making it a "reliable choice" for analog and power design engineers.
