A unique manufacturing process allows Knox Semiconductor to supply a range of Low Voltage Diodes having
Very Low Impedances at Low Current Levels. These remarkably sharp breaking diodes have the lowest values
of impedance ever achieved at the 250µA level. These devices will find wide use in any application where low
currents and low impedances are desired.
