| ZMU100 THRU ZMU180 ZENER DIODES MELF FEATURES Silicon Planar Power Zener Diodes For use in stabilizing and clipping circuits with higher power rating. The Zener voltages are graded according to the international E 12 standard. Smaller voltage tolerances are available upon request. These diodes are also available in the DO-41 case with the type designation ZPU100 ... ZPU180. Cathode Mark .102 (2.6) .094 (2.4) .022 (0.55) .205 (5.2) .189 (4.8) Dimensions are in inches and (millimeters) MECHANICAL DATA Case: MELF Glass Case Weight: approx. 0.25 g MAXIMUM RATINGS Ratings at 25C ambient temperature unless otherwise specified.
