| PWRLITE LD1010D High Performance N-Channel POWERJFETTM with PN Diodes 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 The Power JFET transistor from Lovoltech is a device that presents a Low Rdson allowing for improved efficiencies in DCDC switching applications. The device is designed with a low threshold such that drivers can operate at 5V, which reduces the driver power dissipation and increases the overall efficiency. 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.
