NOTE 1:
The electrical characteristics are measured after allowing the device to stabilize for
20 seconds when mounted with a 9.525 mm (3/8") minimum lead length from the case.
NOTE 2:
The zener impedance is derived from the 50 Hz AC voltage, which results when AC current
having an RMS value equal to 10% of the DC zener current (I
or I
) is superimposed
on I
or I
Zener impedance is measured at two points to insure a sharp knee on the
breakdown curve, thereby, eliminating unstable units.
NOTE 3: Temperature coefficient (

Test conditions for temperature coefficient are as follows.
