Notes:
1. TOLERANCE AND TYPE NUMBER DESIGNATION (VZ)
The type numbers listed have zener voltage min/max limits as shown.
2. SPECIALS AVAILABLE INCLUDE
Nominal zener voltages between the voltages shown and tighter voltage, for detailed information on price, availability and delivery,
contact you nearest Tak Cheong representative.
3. ZENER VOLTAGE (VZ) MEASUREMENT
The zener voltage (VZ) is tested under pulse conditions such that TJ is no more than 2℃ above TA.
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 on IZT or IZK.
