Notes : 1. TOLERANCE AND TYPE NUMBER DESIGNATION (VZ)
The type numbers listed have a standard tolerance on the nmial zener voltage of ±5%.
2. SPECIAL AVAILABLE INCLUDE
Nomial zener voltages shown and tighter voltage, for detailed information on price, availability and delivery,
contact your nearest Taiwan Semiconductor representative.
3. ZENER VOLTAGE (VZ) MEASUREMENT
The zener voltage (VZ) is tested under pulse condition. The measured VZ is guaranteed to be within
specification with device junction in thermal equilibrium.
4. ZENER IMPEDANCE (ZZ) DERIVATION
The 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(IZT or IZK) is superimposed to IZT or IZK.
