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 at a distance of 10mm from case are kept at ambient temperature (3) Measured under thermal equilibrium and DC test conditions 元器件交易网www.cecb2b.com RATINGS AND CHARACTERISTIC CURVES 1N4728 THRU 1N4764 1N4728 ... 1N4764 元器件交易网www.cecb2b.com
