Product introduction：
1. Product Introduction:
SM2329PSA-VB is a single P-channel MOSFET in SOT23-3 package, suitable for the voltage range of VDS to -20V. It adopts Trench technology to provide efficient power switching performance. The VGS voltage of this MOSFET can reach ±12V, and the threshold voltage Vth is -0.8V, which means it can work at a lower gate-source voltage. Its on-resistance (RDS(ON)) performs well at different VGS: 80mΩ at VGS=2.5V, 65mΩ at VGS=4.5V, and 60mΩ at VGS=10V, which is suitable for use in circuits with low voltage and high efficiency requirements. The maximum current carrying capacity is -4A, making it suitable for multiple low-voltage power management and load control applications.
