Product Introduction
VBR9N1219 is a high-performance N-type MOSFET in TO-92 package. Its drain-source withstand voltage (VDS) is 20V, which is suitable for low-voltage applications. The maximum gate-source voltage of this MOSFET is ±12V, ensuring safety under various working conditions. Its threshold voltage (Vth) is 0.6V, indicating that it can be effectively turned on even at low gate voltage. The on-resistance (RDS(ON)) of VBR9N1219 is 25mΩ (VGS = 2.5V), 21mΩ (VGS = 4.5V) and 18mΩ (VGS = 10V) at different gate voltages, providing very low on-resistance and high efficiency. Its maximum continuous drain current (ID) is 4.8A, which is suitable for medium current applications. The use of Trench technology further improves its switching performance and reliability.
