Available as “HR” (high reliability) screened per MIL-PRF-19500, JANTX level. Add “HR” suffix to base part number.
Available as non-RoHS (Sn/Pb plating), standard, and as RoHS by adding “-PBF” suffix. Part numbers listed indicate a tolerance of ±20% with guaranteed limits on only, VZ, IR and
VF.
Devices with guaranteed limits on all six parameters are indicated by suffix A for ±10% tolerance, suffix B for a ±5% tolerance, suffix C for a 2% tolerance and suffix D for a 1%
tolerance.

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.)
