2. TOLERANCE AND VOLTAGE DESIGNATION
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. MAXIMUM ZENER CURRENT RATINGS (I
ZM
)
Values shown are based on the JEDEC rating of 400mW where the actual zener voltage (V
Z
) is known at the operation point, the
zener current may be increased and is limited by the derating curve.
