NOTE 1: The electrical characteristics are measured after allowing the device to stabilize
for 20 seconds when mounted with a 3/8” minimum lead length from the case.
NOTE 2: The zener impedance is derived from the 60HZ ac voltage, which results when an ac current having an r.m.s. value equal to 10% of the DC zener current
(I
ZT
or I
ZK
) is superimposed on I
ZT
or I
ZK
. Zener impedance is measured at two points to insure a sharp knee on the breakdown curve, thereby eliminating unstable units.
NOTE 3: Temperature
