2. TOLERANCE AND VOLTAGE DESIGNATION (V
Zt
)
Tolerance designation – the type numbers listed have zener voltage min/max limits as shown. Device tolerance of
±2%
are
Indicated by a “B” instead of a “C”. Zener voltage is measured with the device junction thermal equilibrium at the temperature
of 30°C
±1°C
and 3/8” lead length.
3. 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.
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.
