Notes:
1. TOLERANCE AND VOLTAGE DESIGNATION
The type numbers listed have zener voltage as shown.
2. ZENER VOLTAGE (V
Z
) MEASUREMENT
The zener voltage is measured under pulse conditions such that T
J
is no more than 2°C above T
A.
3. ZENER IMPEDANCE (Z
Z
) DERIVATION
Zener impedance is derived from the 60-cycle ac voltage, which results when an ac current having an RMS value equal to 10% of the
dc zener current (I
ZT
) is superimposed to I
ZT
.
