Features
ZMM5225 THRU ZMM5262
SILICON PLANAR ZENER DIODES
Silicon Planar Zener Diodes
Standard Zener voltage tolerance is 20%. Add suffix A
for 10% tolerance and suffix B for 5% tolerance.
Other tolerances, non standard and higher Zener voltages
upon request.
These diodes are also availabel in DO-35 case with the type
designation 1N5225 thru 1N5262.
These diodes are delivered typed.

Notes:
(1) The Zener Impedance is derived from the 60Hz AC voltage which results when an AC current having an RMS value
equal to 10% of the Zener current (IZT or IZK) is superimposed on IZT or IZK. Zener Impedance is measured at two
points to insure a sharp knee on the breakdown curve and to eliminate unstable units.
(2) Valid provided that electrodes are kept at ambient temperature.
(3) Measured under thermal equilibrium and DC test conditions.
