The type numbers listed have zener voltage as shown.
Nominal zener voltages between the voltages shown and tighter voltage, for detailed information on price, availability and delivery,
contact you nearest Tak Cheong representative.
The zener voltage is measured under pulse conditions such that T
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
