产品简介：
VBsemi VB2290A is a single P-type field effect transistor with negative drain-source voltage (-20V) and small drain current (-4A) characteristics. Its gate-source voltage range is ±20V, the threshold voltage is -0.8V, and it adopts trench structure technology. When the gate-source voltage is 2.5V, the on-resistance is 89mΩ; when the gate-source voltage is 4.5V, the on-resistance is 60mΩ; when the gate-source voltage is 10V, the on-resistance is 47mΩ. The product is packaged in SOT23-3 and has a small size, making it suitable for use in space-constrained applications.
