where [z.sub.g]--the grid impedance, [Z.sub.gm] = [square root of [R.sup.2.sub.g] + [x.sup.2.sub.g]]--the magnitude of the grid impedance, [[phi].sub.dg] = [[phi].sub.gi] + [[phi].sub.zg]--the phase of the voltage drop in the grid impedance, [[phi].sub.zg] = arctan([x.sub.g]/[R.sub.g])--the phase angle generated by the grid impedance.
This provides a significant advantage, the company said, since most components have connectors and sockets with little, if any, room for checking a voltage drop with the component installed.
Typical forward voltage drop is between 0.33 and 0.41 V, while the use of nickel silicide junctions reportedly eliminates switching losses and enhances the devices' suitability for use in small-sized, high frequency magnetic components.
As shown by the modeling results: increasing the load-switching source, the transition process brings override (voltage drop) is not greater than 10%, but the system is stabilized, if a sufficient source of power.
Features include a capacitance test capability from 1,000 pF to 10,000 mF, diode polarity and voltage drop measurement, and programmable high-voltage ramp time.
