(2) The Zener impedance is derived from the 1KHZ AC voltage which results when an AC current having an RMS value equal to 10% of the Zener current (IZT or IZK) is superimposed on IZT or IZK. Zener impedance is measure at two points to insure a sharp knee on the breakdown curve and to eliminate unstable units. (3) Maximum surge current: Surge current is a non-repetitive,8.3ms pulse width square wave or equivalent sine-wave superimposed on IZT per JEDEC method. (4) Valid provided that electrodes at a distance of 10 mm from case are kept at ambient temperature. 2/3 1SMA4738A thru 1SMA4764A Surface Mount Zener Diodes Vz Range:8.2 to 100V Power Dissipation:1W Ratings and Characteristic Curves (at 25°C unless otherwise specified) Package Outline Dimensions SMA in inches(millimeters) www.goodarksemi.com 3/3 Doc.US1SMA47xxAxGD4.0 .
