Short PDF datasheet, 34.5 KB, for the 1N4728 Zener diode, the first and lowest voltage member of the 1N47xx 1 W Zener family. The document gives the nominal Zener voltage, test current, dynamic impedance and leakage figures needed when replacing a failed clamp or reference diode. Technicians also use it to confirm the package outline and cathode band orientation before fitting a part. Open it in any PDF reader, and note that suffix letters such as A change the voltage tolerance compared with the plain type.
