**SSN3043-VB MOSFET Product Introduction**
SSN3043-VB is a high-efficiency single P-channel MOSFET in a small SOT723-3 package, designed for low voltage and low current applications. Its drain-source voltage (Vds) is -20V, and the gate-source voltage (Vgs) can withstand ±20V, which is suitable for use in medium and low power circuits. The threshold voltage (Vth) of this MOSFET is -0.45V, which can ensure startup and operation at a lower gate voltage. Its on-resistance (Rds(on)) is 380mΩ at Vgs = 10V and 456mΩ at Vgs = 4.5V, providing good current conduction performance, and the maximum drain current (Id) is -0.78A, which is suitable for low-power load switches, power management and other low-power applications. SSN3043-VB uses Trench technology, has excellent switching characteristics, effectively reduces switching losses, and improves work efficiency.
