BSS138-T-VB Product details
Back to previous pageProduct introduction：
Still troubled by high voltage drop and high control power consumption in low-voltage signal switches? VBsemi BSS138-T-VB is here to help! This SOT23-3 packaged N-MOSFET, compact yet capable of handling 60V voltage and 0.3A current switching tasks, features an ultra-low on-resistance of 2.8Ω @ 10V. With Trench technology for fast switching and low losses, it is especially suitable for logic level shifting, signal switching, and low-power load driving—making it the "worry-free choice" for embedded and portable device designs.
