FEATURES
Trench Power JFET with low threshold voltage Vth. Device fully “ON” with Vgs = 0.7V Optimum for “Low Side” Buck Converters Optimized for Secondary Rectification in isolated DC-DC Low Rg and low Cds for high speed switching No “Body Diode”; extremely low Cds Added Fast Recovery Schottky Diode in same package DESCRIPTION
Lower threshold produces faster turn-on/turn-off, which minimizes the required dead time. The transistor “No Body Diode” provides a very low associated parasitic capacitance Cds. A Schottky Diode is added for applications where a freewheeling diode is required. Ringing is also reduced so that a lower voltage device may be a better solution. APPLICATIONS
