Taiwan Semiconductor
Notes:
1. Tolerance and voltage designation : the type numbers listed have Zener voltage as shown
2. Specials available include, nominal zener voltages between the voltages shown and tighter voltage, for detailed
3. Zener voltage (VZ) measurement, the zener voltage is measured under pulse condicitons such that TJ is no
more than 2oC above TA
4. Zener impedance (ZZ) derivaton, 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) is superimposed to IZT
