PDF datasheet of 64.7 KB covering Zener diodes from 1N4728A to 1N4754A, a subset of the 1 W axial Zener series. Each type number maps to a nominal Zener voltage, given in the table together with test current, maximum impedance and leakage values. In repair work the sheet helps decode the marking on a failed Zener used as a voltage clamp, bias reference or overvoltage protector and choose an equivalent. Any PDF viewer opens it, and power dissipation and voltage tolerance should be checked before substitution.
