Zener Impedance is measured at two points to insure a sharp knee on the breakdown curve and to eliminate unstable units. 2) 3) 4) Valid provided that electrodes are kept at ambient temperature. Measured under thermal equilibrium and DC test conditions. Tested with pulses tp = 20 ms. ZMM5221...ZMM5264 |
