MBR340 Preferred Device Axial Lead Rectifier This device employs the Schottky Barrier principle in a large area metaltosilicon power diode. Stateoftheart geometry features epitaxial construction with oxide passivation and metal overlap contact. Ideally suited for use as rectifiers in lowvoltage, highfrequency inverters, free wheeling diodes, and polarity MBR340 ELECTRICAL CHARACTERISTICS (T = 25C unless otherwise noted) (Note 3) L Characteristic Symbol Max Unit Maximum Instantaneous Forward Voltage (Note 4) v V F (i = 1.0 Amp) 0.500 F (i = 3.0 Amp) 0.600 F (i = 9.4 Amp) 0.850 F Maximum Instantaneous Reverse Current Rated dc Voltage (Note 4) i mA R T = 25C 0.60 L T = 100C 20 L 3.
