2. TOLERANCE AND TYPE NUMBER DESIGNATION (V
Z
)
The type numbers listed have a standard tolerance on the nominal zener voltage of
±
5%.
3. ZENER VOLTAGE (V
Z
) MEASUREMENT
The zener voltage (V
Z
) is tested under pulse condition. The measured
V
Z
is guaranteed to be within specification with device
junction in thermal equilibrium.
4. ZENER IMPEDANCE (Z
Z
) DERIVATION
Z
ZT
and
Z
Zk
are measured by dividing the AC voltage drop across the device by the AC current applied. The specified limits are
for I
Z(AC)
= 0.1
I
Z(DC)
with AC frequency = 60Hz.
5. TEMPERATURE COEFFICIENT (θ
VZ)
Test conditions for temperature coefficient are as follows:
A. I
ZT
= 7.5mA, T1 = 25℃, T2 = 125℃ (1N5221B through 1N5242B)
B.
