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
Nominal zener voltage is measured with the device junction in the thermal equilibrium at the lead temperature (T
L
) at 30°C
±1°C
and 3/8” lead length.
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
)
This data was calculated using nominal voltages. The maximum current handling capability on a worst case basis is limited
by the actual zener voltage at the operation point and the power derating curve.
