ZMM1B...ZMM200B
SILICON PLANAR ZENER DIODES
in MiniMELF case especially for automatic insertion. The Zener
voltages are graded according to the international E 24
standard. Smaller voltage tolerances and higher Zener voltages
are upon request.
LL-34
These diodes are also available in DO-35 case with the type
designation BZX55B
