MELF
FEATURES
♦ Silicon Planar Power Zener Diodes
♦ For use in stabilizing and clipping circuits with high
Cathode Mark

♦ Standard Zener voltage tolerance is ±10%. Add suf-
fix “A” for ±5% tolerance. Other Zener voltages and
tolerances are available upon request.

NOTES:
(1) The Zener impedance is derived from the 1KHZ 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 at a distance of 10mm from case are kept at ambient temperature
)
(3) Measured under thermal equilibrium and DC test conditions
