SSM3J371R,LF-VB Product details
Back to previous pageProduct introduction：
Still worried about heat generation and board space in low-voltage power management? Let VBsemi SSM3J371R, LF-VB solve your worries! This SOT23-3 packaged P-MOSFET, though the size of a grain of rice, can handle -5A current, with an on-resistance as low as 34mΩ, offering superior power performance compared to similar devices. The Trench process provides sharp switching characteristics and low losses, and the -20V withstand voltage easily covers typical low-voltage scenarios such as portable devices, battery protection, and load switching, making it a flexible power switch tool in the hands of engineers.
