LD1003S

PWRLITE LD1003S High Performance N-Channel POWERJFETTM with Schottky Diode 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 www.DataSheet4U.com ™ 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.
