Zener Impedance is measured at two points to insure a sharp knee on the breakdown curve and to eliminate unstable units. 2) Valid provided that electrodes are kept at ambient temperature. 3) Measured under thermal equilibrium and DC test conditions. 155ITT SEMICOND/ INTERMETALL bLE D MM 4682711 0003219 O54 MISSI ZMM5225 . . .
