Zener diode datasheet covering the range from 1N4728A to 1N4764A, an 88.2 KB PDF. This 1 W axial Zener series spans a wide range of nominal voltages, each part number corresponding to a specific Zener voltage listed in the electrical table. Technicians use it to identify the voltage of a marked Zener, confirm test current and dynamic impedance, and pick a replacement for a clamp or reference circuit. It opens in any PDF reader, and the tolerance suffix on the actual part should be compared with the table.
