*JEDEC Registered Data
NOTES:
1.
The JEDEC type numbers shown with an A suffix have a 5% tolerance on nominal zener voltage. No suffix signifies a 10% tolerance,
C signifies 2%, and D signifies 1% tolerance. Also add a P suffix for designating plastic construction (or G suffix for glass body).
2.
The Zener impedance is derived from the 60 Hz ac voltage that results when an ac current having an rms 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 ensure a sharp knee on the
breakdown curve and eliminate unstable units. See MicroNote 202 for zener impedance variation with different operating currents.
3.
The reverse surge current is measured at 25
C ambient using a square wave or equivalent half-sine wave pulse 1/120 second duration
superimposed on I
ZT
.
4.
Zener voltage (V
Z
) is measured at T
L
= 25oC (+8, -2oC) and 90 seconds after application of dc current.
