Note:
1) Tolerance and voltage designation
Tolerance designation- the type numbers listed have zener voltage min/max limits as shown.
2) Reverse zener voltage (VZ) Measurement
Reverse zener voltage is measured under pulse conditions such that Tj is no more than 2OC above
TA
3) Zener impedance (ZZ) derivation
ZZT and ZZK are measured by dividing the ac voltage drop across the device by the ac current
applied. The specified limits are for IZ(ac)=0.1 IZ(dc) with the ac frequency=1.0KHz.
