| ZMY1 THRU ZMY100 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 E24 standard. Smaller voltage tolerances and other Zener voltages are available upon request. These diodes are also available in the DO-41 case with the type designation ZPY1 ... ZPY100. 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.

Hence, the index of all characteristics and maximum ratings should be "F" instead of "Z". Connect the cathode terminal to the negative pole For devices in glass case MELF with higher Zener voltage but same power dissipation see types ZMU100 ...
