BZX85 Series VZ Range: 3.6 to 200 Volts Features Silicon Planar Power Zener Diodes. For use in stabilizing and clipping circuits with high power rating. The Zener voltages are graded according to the international E 24 standard. Replace suffix "C" with "B" for ±2% tolerance. Other voltage tolerances and other Zener voltages are available upon request. Mechanical Data Case: DO-41Glass Case Weight: approx. 0.35g Maximum Ratings and Thermal Characteristics (TA=25oC unless otherwise noted) Parameter Symbol Value Unit Zener current (see Table "Characteristics") Power dissipation at Tamb=25oC Ptot 1.3 (1) Thermal resistance junction to ambient air RθJA 130 (1) Junction temperature Storage temperature range Notes: Tj TS W o C/W 175 o C -55 to +175 o C 1.
