1N4565AUR-1 thru 1N4584AUR-1 are CDI low current temperature compensated zener reference diodes, packaged as DO-213AA with leads, suitable for surface mounting, working current range is 0.5-4.0mA.
The CDLL4565‑CDLL4584A series are surface‑mount, lead‑less Zener reference diodes with low‑current operating ranges from 0.5 mA to 4 mA. They are offered in hermetically sealed DO‑213AA, MELF, SOD‑80, and LL34 packages and are designed for operation from –65 °C to +175 °C.
Key electrical specifications include a reverse leakage current of 2 µA at 25 °C with a 3 V reverse bias, a DC power dissipation of 500 mW at +50 °C, and a power‑derating factor of 4 mW/°C above +50 °C. Temperature coefficient data and Zener impedance curves are provided for design reference.
