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 coefficient (α
VZ
). Test conditions for temperature coefficient are a follows:
a. I
ZT
= 7.5 mA, T
1
= 25°C,
T
2
= 125°C (1N5221A, thru 1N5242A, B.)
b. I
ZT
= Rated I
ZT
, T
1
= 25°C,
T
2
= 125°C (1N5243A, B thru 1N5281A, B.)
Device to be temperature stabilized with current applied prior to reading breakdown voltage at the specified ambient temperature.
