ZMM51 - General Semiconductor, Inc.

FEATURES

♦Silicon Planar Zener Diodes

♦In Mini-MELF case especially for automatic insertion.

♦The Zener voltages are graded according to the

international E 24 standard. Smaller voltage

tolerances and other Zener voltages are available

upon request.

♦These diodes are also available in DO-35 case with the type

designation ZPD1 … ZPD51.

NOTES:

(1) Tested with pulses tp= 5 ms

(2) Valid provided that electrodes are kept at ambient temperature

(3) The ZMM1 is a silicon diode operated in forward direction. Hence, the index of all parameters should be “F” instead of “Z”

Connect the cathode electrode to the negative pole
