The document contains the maximum ratings, electrical characteristics, and parameters of a series of diode products manufactured by CDI Diodes. These diodes have different rated voltages and currents, suitable for various application scenarios.
The CDI handbook covers the 1N5518 through 1N5546D series of Zener diodes. It lists maximum ratings, electrical parameters, and mechanical design details for each part number.
Key sections include maximum ratings such as junction temperature and power dissipation, detailed electrical characteristics at 25 °C, and design data like case type, lead material, and thermal resistance. Graphs illustrate Zener impedance versus operating current.

The diodes operate from –65 °C up to +175 °C.
The maximum DC power dissipation is 500 mW at a case temperature of +50 °C.
The forward voltage is limited to 1.1 V maximum at 200 mA.
Thermal resistance is 250 °C/W maximum when the lead length is 0.375 in.
