The RD2.0UM to RD39UM series are 2-pin Ultra Super Mini Mold Package zener diodes possessing an allowable power dissipation of 150 mW.
The RD2.0UM to RD39UM series are 2‑pin ultra‑super‑mini molded zener diodes with a maximum power dissipation of 150 mW. They are offered in a compact 30 × 30 × 0.75 mm ceramic package and are suitable for constant‑voltage, constant‑current, waveform clipping, and surge‑absorbing circuits.
The sheet provides detailed electrical characteristics for each voltage grade, including Zener voltage ranges, dynamic impedance, and reverse current. Typical characteristic curves, transient thermal impedance, and surge reverse power ratings are also included to aid designers in selecting the appropriate part for their applications.
