NOTE
1: Table as shown lists type numbers, which indicate a tolerance of 20% with guaranteed limits on only Vz, I
R
, and V
F
. Devices with
guaranteed limits on all six parameters are indicated by suffix "A" for 10%, "B" for 5%, "C" for 2%, and "D" for 1% tolerance
NOTE
2: The electrical characteristics are measured after allowing the device to stabilize for 20 seconds.
NOTE
3: Temperature coefficient (
VZ
). Test conditions for temperature coefficient are as follows:
a. I
ZT
= 7.5mA, T
I
= 25
o
C T
